Abstract
The ideal sagittal position of the maxilla is highly subjective in orthognathic surgical treatment planning. There is no consensus on an analysis to predict the ideal sagittal position of the maxilla. The objective of this study was to determine the preferred maxillary position in relation to the forehead shape, in the Southern Chinese population. The maxilla position of eight patients was simulated based on Steiner's analysis (SA), glabella vertical (GV), Andrews' Element II (AE2), and the Barcelona reference (BR). The simulations were then used in an electronic survey, where respondents ranked the images for each patient from to 1-4 (most to least attractive). A total of 128 responses were collected from dental professionals and laypersons. The most preferred to the least preferred simulation was as follows (mean rank scores for the male and female patients in parenthesis): BR (males 2.06; females 1.98), GV (males 2.11; females 2.21), SA (males 2.59; females 2.40), and AE2 (males 3.24; females 3.41). There was no significant difference in the results according to the sex, age group, or profession of the respondents. The Barcelona reference and glabella vertical are useful in predicting the ideal maxillary position in patients with a flat forehead, and the Barcelona reference is the most preferred in patients with a rounded forehead.

Abstract
BACKGROUND The establishment of good facial esthetics is one of the main objectives of complete denture construction. Unfortunately, it may be the caused issue for patients having a prominent premaxilla due to excessive lip support by the labial flange of the maxillary denture. Open-face dentures (OFD) may suggest suitable prosthetic management for these patients. However, clinical evidence regarding the efficiency of OFD is scarce. METHODS A total of 38 completely edentulous participants having prominent premaxilla and skeletal class I Angle's classification were enrolled in this study. Each participant received a mandibular complete denture and 2 opposing maxillary dentures; conventional (CD) and open-face (OFD). On the day of denture insertion, the participants were divided into 2 groups; CD-OFD and OFD-CD where CD-OFD group was instructed to use the mandibular denture and the maxillary CD for 3 months and then to use the maxillary OFD for another 3 months after a wash-out period of 2 weeks. While group OFD-CD was instructed to use the mandibular denture and the maxillary OFD for 3 months then to use the maxillary CD for another 3 months after a wash-out period of 2 weeks. The dislodging force of the maxillary dentures was evaluated using the universal testing machine and the patient perception of retention, esthetics, and comfort was evaluated using the Visual Analogue Scale (VAS). Evaluation was carried out 1 day, 1 month, and 3 months after denture insertion. The Student t-test was used to compare the 2 maxillary dentures and the intervals for each denture were compared by using the ANOVA test with repeated measures followed by a Post Hoc test (adjusted Bonferroni) for pairwise comparison. RESULTS The significance of the obtained results was judged at the 5% level (P value). The dislodging force and patient perception of retention did not show significant differences between the 2 dentures, while the perception of esthetics showed significant differences throughout the follow-up period. Perception of comfort showed an insignificant difference only at the 3-month interval. CONCLUSIONS Open-face maxillary dentures can be a suitable alternative for patients with prominent premaxilla to achieve satisfactory retention, aesthetics, and comfort.

Abstract
This study aimed to compare the functional and esthetic results in patients following mandibular reconstruction with a free fibula flap (FFF) by virtual surgical planning (VSP) versus the conventional technique. Patients who had undergone mandibular reconstruction with a FFF by VSP or the conventional technique were retrospectively assessed. The two groups were compared regarding functional and esthetic variables with appropriate scales preoperatively, intraoperatively, and postoperatively. Twenty-four patients were evaluated in two groups: conventional (n = 8) and VSP (n = 16). The mean amount of mandibular asymmetry was 2.62 mm (SD = 1.59) in the conventional group and 1.19 mm (SD = 1.32) in the VSP group. Of the patients who underwent conventional surgery, 12.5% had mandibular asymmetry of <2 mm and 87.5% had asymmetry of 2-5 mm. Of the VSP patients, 61.5% had mandibular asymmetry of <2 mm and 38.5% had mandibular asymmetry of 2-5 mm (p = 0.03). The mean difference in size of mandibular angle on the surgical and control sides was not significantly different between the two groups (p = 0.62). The difference in mean length of the mandibular body on the surgical side relative to the control side was not significant between the two groups (p = 0.75). Differences in functional variables between the two groups were not significant. Within the limitation of the study, it seems that the VSP technique resulted in better facial symmetry and superior esthetic outcomes compared with the conventional technique.

Abstract
INTRODUCTION The goal of lower-extremity reconstructions is primarily to salvage the leg; however, esthetic outcomes are also important. This study aimed to assess the impact of a lower extremity free tissue transfer regarding social functioning, patient-reported esthetic outcomes, and possible differences between fasciocutaneous vs. muscle flaps. MATERIAL AND METHODS For this cross-sectional multicenter study, patients operated between 2003 and 2021, with a minimum follow-up of 12 months, were identified. Outcomes were obtained from 89 patients. Patient-reported outcomes were assessed using a questionnaire containing 5-point Likert scale questions grouped in three groups: aspect of the reconstructed leg, the aspect of the donor site, and the negative impact on social functioning. Physical functioning and mental health were assessed with the Short-Form-36. RESULTS The overall score for negative impact on social functioning was 22.2. This was 46.7 for the esthetic satisfaction of the reconstructed leg and 57.1 for the donor site. No significant differences were seen between patients who underwent a reconstruction with a fasciocutaneous flap compared to a muscle flap. Secondary surgical procedures for improving the esthetic aspect were performed in 12% of the patients in the fasciocutaneous group and 0% in the muscle group. CONCLUSION Our results show that the most optimal esthetic outcome is not defined by the type of flap. We found a strong correlation between physical functioning and the negative impact on social functioning that a reconstructed lower extremity may have. The result of this study can be taken into consideration during the shared decision-making process of choosing the most optimal reconstruction.

Abstract
INTRODUCTION Esthetics plays a crucial role in orthodontics and many other dental and medical fields. To date, no study has assessed the combined effects of the 3 facial features 'facial height, gingival display (GD), and buccal corridor size (BC)' on facial/smile beauty. Therefore, this study was conducted for the first time. METHODS In this psychometric diagnostic study, beauty of 27 randomized perceptometric images of a female model with variations in facial heights (short, normal, long), gingival displays (0, 2, 4, 6 mm), and buccal corridor sizes (2%, 10%, 15%, 20%, 25%) were evaluated by 108 judges (36 orthodontists, 36 dentists, 36 laypeople) using a 5-scale Likert scale (1 to 5). Combined effects of facial heights, GDs, BCs, judges' sexes, ages, and jobs, and their 2-way interactions were tested using a mixed-model multiple linear regression and a Bonferroni test. Zones of ideal features were determined for all judges and also for each group using repeated-measures ANOVAs and the Bonferroni test (α=0.05). RESULTS Judges' sex but not their age or expertise might affect their perception of female beauty: men gave higher scores. The normal face was perceived as more beautiful than the long face (the short face being the least attractive). Zero GD was the most attractive followed by 4 mm; 6 mm was the least appealing. BCs of 15% followed by 10% were the most attractive ones, while 25% BC was the worst. The zone of ideal anatomy was: long face + 0mm GD + 15% BC; normal face + 2mm GD + 15% BC; long face + 2mm GD + 15% BC; normal face + 0mm GD + 15% BC. CONCLUSIONS Normal faces, zero GDs, and 15% BCs may be the most appealing. Facial heights affect the perception of beauty towards GDs but not BCs.

Abstract
BACKGROUND This study aimed to evaluate the use of fat grafting enriched with platelet-rich plasma through a computerized-assisted mapping for esthetic restoration in progressive hemifacial atrophy (Parry-Romberg disease). METHODS This prospective study was conducted on 53 patients presented by Parry-Romberg disease and was corrected by facial fat grafting (FFG) enriched with platelet-rich plasma (PRP). A computerized software program was used to design a detailed map to achieve clinical symmetry with fat grafting application, as the anatomical subunits direct 3-dimensional volumetric symmetric, and compartments direct isolated recipient-specific grafting. Also, volumetric asymmetry was assessed through outlines of facial contour, projection, and proportions for both sides and comparing the mirror image of unaffected side as a template. RESULTS Objective ultrasound and photogrammetric measurements showed a significant improvement in facial symmetry postoperatively compared to preoperative (P < 0.05), with no significant differences between 12 and 18 months after surgery. The FACE-Q score regarding comparison before surgery and 18 months after surgery showed a statistically significant improvement in all modules (P < 0.001) with overall satisfaction concerning outcome of 82.7 ± 0.8. CONCLUSION Enriched fat grafting with platelet-rich plasma (PRP) is a good alternative to reconstruct soft tissue defects for patients with progressive hemifacial atrophy (Parry-Romberg disease) with a minimally invasive approach and low complications. It provides volumetric replacement, enhancement of skin texture, and improvement of hyperpigmentation with restoration of facial contour for an esthetic pleasing appearance. Isolated replacement in accordance with the anatomical facial subunits and fat compartments allows three-dimensional reconstruction and maximizes fat retention.

Abstract
OBJECTIVE To describe, according to the CARE guidelines, an easily reproducible technique using two local muscle flaps to reduce the unsightly retromandibular hollow left by total parotidectomy for cancer. CASE DESCRIPTION A 40-year-old Caucasian male with T3N1M0 temporal skin melanoma was managed by skin resection, conservative total parotidectomy and ipsilateral level II-IV selective lymph-node dissection. Two rotational muscle flaps were taken from the ipsilateral posterior belly of the digastric and sternocleidomastoid muscles. Postoperative course was uneventful, with 3 days' hospital stay, without facial or spinal palsy. At 3 days, 3 months and 9 months postoperatively, the appearance of the parotid region was similar to the non-operated contralateral region. CONCLUSION Easy to perform and without associated scars, the approach described here should be included in the armamentarium available to the head and neck surgeon to avoid an unsightly hollow after total parotidectomy for cancer, in an effort to improve quality of life.

Abstract
The popularity of esthetic medicine is growing every year, also among patients with autoimmune inflammatory rheumatic diseases (AIRD). The objective of this study was to evaluate the safety of esthetic medicine (AM) procedures in patients with AIRD. A semi-structured, anonymous questionnaire regarding rheumatic and concomitant diseases and AM procedures was distributed among adult patients hospitalized in the rheumatology department or attending outpatient clinic in the National Institute of Geriatrics, Rheumatology, and Rehabilitation, Warsaw. The main outcome was the occurrence of an adverse event. A number of 512 patients took part in the survey and 15 were excluded (AM procedure preceded the diagnosis of AIRD). The study group consisted of 497 patients, of whom 47 had undergone AM procedures. The procedures performed included: tattooing (22 patients), piercing (16 patients), hyaluronic acid (7 patients), botulinum toxin (5 patients) injections, laser procedures (6 patients), plastic surgery (4 patients), mesotherapy (3 patients) and others. The vast majority of patients had these performed during remission or low disease activity. 70.2% of patients received treatment with disease-modifying antirheumatic drugs (DMARDs) during the AM procedure, with TNF-alfa inhibitors being the most common (63.6%). Adverse events occurred in 15% of patients. All were mild and transient site reactions. Most patients would like to repeat the AM procedure in the future. The use of esthetic medicine procedures in patients with AIRD, including those treated with biologic DMARDs, was associated with a risk of mild site reactions. Most of the patients expressed satisfaction with the results of the AM procedure.

Abstract
OBJECTIVES This study investigated age-related differences in nasal morphometry and the degree of changes within an individual over at least a 10-year period by pairing previous and recent three-dimensional reconstructed computed tomography (CT) images. METHODS Forty-eight adult Korean patients who underwent at least two CT scans of the nasal region with an interval of at least 10 years were selected. Patients were categorized into six subgroups according to sex and age (20-39 years, 40-49 years, and ≥50 years) at the time of initial imaging. Eight nasal parameters were measured on the initial and recent images, and paired comparisons between the two images were performed based on the data. The differences in the degree of change by age were also analyzed. RESULTS Over an average image interval of 12 years, men exhibited an increase in the nasofrontal angle (3.2°±5.4°, P=0.041), profile nasal length (1.7±1.7 mm, P=0.002), and nasal bridge height (1.2±1.6 mm, P=0.002). Conversely, they showed a decrease in the nasofacial angle (-2.3°±2.9°, P=0.010). Women also demonstrated an increase in the nasofrontal angle (2.5°±5.2°, P=0.010), profile nasal length (1.4±1.9 mm, P<0.001), and nasal bridge height (1.3±1.6 mm, P<0.001). However, they exhibited a decrease in the nasofacial angle (-2.0°±2.1°, P<0.001), glabella angle (-9.1°±9.8°, P<0.001), and pyriform angle (-8.5°±10.1°, P<0.001). With the exception of the nasal bridge height (P=0.036) and pyriform angle (P=0.022), the degree of changes in most parameters did not show significant differences across age groups. CONCLUSION Our findings indicate that the aging nose exhibits a greater nasal length with inferior angulation of the nasal tip, with an increase in the nasofrontal angle, profile nasal length, and nasal bridge height, along with a decrease in the nasofacial angle. The degree of most nasal morphologic changes demonstrated no significant differences by specific age group.

Abstract
PURPOSE This study aims to evaluate the accuracy of different shade selection techniques and determine the matching success of crown restorations fabricated using digital shade selection techniques. MATERIALS AND METHODS Teeth numbers 11 and 21 were prepared on a typodont model. For the #11 tooth, six different crowns were fabricated with randomly selected colors and set as the target crowns. The following four test groups were established: Group C, where the visual shade selection was performed using the Vita 3D Master Shade Guide and the group served as the control; Group Ph, where the shade selection was performed under the guidance of dental photography; Group S, where the shade selection was performed by measuring the target tooth color using a spectrophotometer; and Group I, where the shade selection was performed by scanning the test specimens and target crowns using an intraoral scanner. Based on the test groups, 24 crowns were fabricated using different shade selection techniques. The ΔE values were calculated according to the CIEDE2000 (2:1:1) formula. The collected data were analyzed by means of a one-way analysis of variance. RESULTS For the four test groups (Groups C, Ph, S, and I), the following mean ΔE values were obtained: 2.74, 3.62, 2.13, and 3.5, respectively. No significant differences were found among the test groups. CONCLUSION Although there was no statistically significant difference among the shade selection techniques, Group S had relatively lower ΔE values. Moreover, according to the test results, the spectrophotometer shade selection technique may provide more successful clinical results.

Abstract
INTRODUCTION Division of the suspensory ligament of the penis has emerged as a popular surgical approach for penile lengthening, but accurate preoperative predictions of lengthening outcomes remain elusive. This study aimed to identify readily measurable anatomical parameters associated with post-ligamentolysis penile length gain, facilitating more reliable preoperative estimations. METHODS An experimental cross-sectional study was performed on 16 adult cadavers. Data collected before dissection included: age at death, ethnicity, height, length of the penis before dissection and width of the suspensory ligament of penis. Following the complete dissection of the suspensory ligament of penis, the depth of the pubic symphysis and the penile length after the procedure were measured. The absolute and relative length differences pre- and post-ligamentolysis were calculated. Correlation coefficients were used to study relations between these variables. RESULTS Penile length increased uniformly after complete division of the suspensory ligament (average gain: 26.38 mm, SD = 14.83 mm; range 4-60 mm). Pearson correlation revealed a significant negative correlation between pre-ligamentolysis penile length and post-ligamentolysis increase (r = - 0.601; p = 0.014), suggesting greater gains in individuals with shorter pre-ligamentolysis lengths. Age, ligament width, and pubic arch depth showed no significant correlations. Ethnicity did not impact post-ligamentolysis length increase (t = - 0.135; p = 0.894). CONCLUSIONS This study highlights the potential to predict penile length gain post-ligamentolysis through measurable anatomical parameters. The ability to anticipate the outcome of this procedure could empower surgeons to provide informed counseling, potentially elevating patient satisfaction. An experimental cross-sectional study was performed to investigate the outcomes of penile lengthening surgery Penile lengthening was achieved in all subjects via complete dissection of the suspensory ligament of the penis Penile length increase may be predicted preoperatively using easily measurable anatomical parameters NO LEVEL ASSIGNED: This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Abstract
AIM To evaluate the surface electromyography (sEMG) activity of the superficial masseter and anterior temporalis muscles at rest, during maximum voluntary clenching (MVC), and mastication, over 6 months of wearing clear thermoplastic or wrap-around retainers. Furthermore, the patients' oral health-related quality of life was assessed using the Oral Impacts on Daily Performance (OIDP) index at 6 months. MATERIALS AND METHODS Sixty patients aged 14-39 years (19 males/41 females) who received upper and lower retainers after finishing orthodontic treatment were recruited. The patients were randomly divided into a clear thermoplastic retainer group (n = 30) or a wrap-around retainer group (n = 30). The sEMG activity was recorded at retainer delivery (T0), after 3 months (T1), and after 6 months of wearing (T2). The OIDP index was evaluated at T2. RESULTS None of the sEMG parameters for the masseter and temporalis muscles were different between the two groups at T0, T1, or T2. Over the period of 6 months, both masticatory muscles in both groups demonstrated increased sEMG activity during MVC and mastication; however, only the temporalis muscle demonstrated decreased normalized sEMG activity at rest (P < 0.05). The frequency and severity of the OIDP in the eating aspect at T2 was low and similar in both groups. CONCLUSIONS sEMG activity of the two masticatory muscles tended to increase during MVC and mastication, while temporalis muscle activity tended to decrease at rest during the observation period, regardless of retainer type. Notably, these sEMG changes did not affect the patients' subjective masticatory function.

Abstract
Background The clinical teaching of esthetic implant-supported restoration of the atrophic maxilla is challenging due to the complexity and unpredictability of bone and soft tissue augmentation. The traditional problem-based learning and case-based learning method (PBL-CBL method) with a full digital workflow (digital PBL-CBL method) provides the students a chance to view clinical cases in a more accurate and measurable way. The aim is to evaluate the effectiveness of the new digital PBL-CBL method in teaching complex implant cases in esthetic area. Materials & Methods A full digital workflow of dental implant therapy was established for patients with severely atrophic anterior maxilla. The digital data of cases done in the new workflow was used as teaching materials in digital PBL-CBL teaching. Fifty-four postgraduate students were randomly selected and divided into three groups, including traditional PBL-CBL group (students taught in a PBL-CBL method with no digital cases), digital PBL-CBL group (students taught in a PBL-CBL method with full digital cases) and control group (students taught in didactic teacher-centered method). After training for three months, a study of the students' opinions on the corresponding teaching method was carried out through a feedback questionnaire. A theory test was used to evaluate students' mastery of knowledge about tissue augmentation and esthetic implant restoration. A case analysis was used to determine whether students could apply the knowledge to problem solving. Results The digital PBL-CBL method resulted in a higher rate of satisfaction than the traditional PBL-CBL method and the didactic teacher-centered method in all items except for "This approach decreases extracurricular work". Case analysis scores of the digital PBL-CBL group were significantly higher than that of the traditional PBL-CBL group and the control group. For the theory test, the digital PBL-CBL group (61.00 ± 6.80) but not traditional PBL-CBL group (55.22 ± 9.86) obtained a significant higher score than the control group (45.11 ± 12.76), although no significant difference was found between the digital PBL-CBL group and the traditional PBL-CBL group. Conclusion Compared with other methods, students taught with the digital PBL-CBL method showed higher satisfaction and better performance in acquisition of academic knowledge and ability in solving practical clinical problems. The digital PBL-CBL method provided a promising alternative for teaching complex implant cases at the anterior maxilla.

Abstract
BACKGROUND The evaluation of the facial profile of skeletal Class II patients with camouflage treatment is of great importance for patients and orthodontists. The aim of this study is to explore the key factors in evaluating the facial profile esthetics and to predict the posttreatment facial profile esthetics of skeletal Class II extraction patients. METHODS 124 skeletal Class II extraction patients were included. The pretreatment and posttreatment cephalograms were analyzed by a trained expert orthodontist. The facial profile esthetics of pretreatment and posttreatment lateral photographs were evaluated by 10 expert orthodontists using the visual analog scale (VAS). The correlation between subjective facial profile esthetics and objective cephalometric measurements was assessed. Three machine-learning methods were used to predict posttreatment facial profile esthetics. RESULTS The distances from lower and upper lip to the E plane and U1-APo showed the stronger correlation with profile esthetics. The changes in lower lip to the E plane and U1-APo during extraction exhibited the stronger correlation with changes in VAS score (r = - 0.551 and r = - 0.469). The random forest prediction model had the lowest mean absolute error and root mean square error, demonstrating a better prediction accuracy and fitting effect. In this model, pretreatment upper lip to E plane, pretreatment Pog-NB and the change of U1-GAll were the most important variables in predicting the posttreatment score of facial profile esthetics. CONCLUSIONS The maxillary incisor protrusion and lower lip protrusion are key objective indicators for evaluating and predicting facial profile esthetics of skeletal Class II extraction patients. An artificial intelligence prediction model could be a new method for predicting the posttreatment esthetics of facial profiles.

Abstract
This case report describes our treatment of a persistent periantral abscess in a 35-year-old woman. The abscess developed following a zygoma-reduction surgery, during which a preexisting fungal ball had not been addressed. Our comprehensive treatment approach included functional endoscopic sinus surgery, fungal ball removal, abscess drainage, and debridement. Two weeks postoperatively, the patient's symptoms had resolved. A 6-month postoperative follow-up revealed no signs of recurrence or complications, and the patient reported satisfactory functional and aesthetic results. This case underscores the importance of thorough preoperative evaluations and raises awareness about the potential risks of untreated asymptomatic pathologies, which can potentially progress and lead to further complications.

Abstract
OBJECTIVES To evaluate in vitro the effects of sodium fluoride (F) and nano-sized sodium trimetaphosphate (TMPnano) added to a 35% hydrogen peroxide (H2O2) bleaching gel on the color alteration, enamel mechanical and morphological properties, and H2O2 transamelodentinal diffusion. MATERIALS AND METHODS Bovine enamel/dentin discs (n = 180) were divided according to the bleaching gel: 35% H2O2 (HP); 35% H2O2 + 0.1% F (HP/F); 35% H2O2 + 1% TMPnano (HP/TMPnano); 35% H2O2 + 0.1% F + 1% TMPnano (HP/F/TMPnano) and 35% H2O2 + 2% calcium gluconate (HP/Ca). The gels were applied 3 times by 40 min; once each 7-day. The Commission Internationale de l'Eclairage (CIE) L*a*b* total color alteration (ΔE), color alteration by CIEDE2000 (ΔE00), whitening index (ΔWID), surface (SH) and cross-sectional hardness (ΔKHN), surface roughness (Ra), and transamelodentinal diffusion were determined. Enamel surfaces were evaluated by Scanning Electron Microscopy (SEM) and X-ray Dispersive Energy (EDX). Data were submitted to ANOVA, followed by the Student-Newman-Keuls test (p <0.05). RESULTS ΔE, ΔE00, and ΔWID were similar among the gels that promoted a bleaching effect after treatment (p <0.001). Mineral loss (SH and ΔKHN), Ra, and H2O2 diffusion were lower for HP/F/TMPnano; the HP and HP/Ca groups presented the highest values (p <0.001). For SEM/EDX, surface changes were observed in all bleached groups, but less intense with TMPnano. CONCLUSIONS Gels containing F/TMPnano do not interfere with the bleaching effect and reduce enamel demineralization, roughness, H2O2 diffusion, and morphological changes. CLINICAL RELEVANCE Whitening gels containing F/TMPnano can be used as a new strategy to increase safety and maintain clinical performance.

Abstract
Nowadays, aesthetic concerns have gained attention, especially by patients looking for a less invasive alternative to minor facial corrections. Polymethylmethacrylate (PMMA) is widely used as a soft tissue filler; the demand for this polymer has increased, and along with it, there are some reports of adverse reactions. Such adverse reactions stem from consequences of immune and inflammatory reactions to PMMA. Some animal models have been used to unravel the causes of these reactions, among other factors involving the management of PMMA. The aim of this study was to determine the immunogenic profile of PMMA implantation in different anatomical planes of mice, over up to 360 experimental days. In this study, BALB/c mice were divided into 30 groups for immune evaluation of the interaction between the organism and the polymer; 2% PMMA was implanted subcutaneously, 10% intramuscularly and 30% in periosteal juxtaposition and followed during five experimental days (7, 30, 90, 180 and 360 days after implantation-DAI). Pro- and anti-inflammatory cytokines (IL-2, IL-4, IL-6, IFN-gamma, TNF, IL-17A, IL-10 and TGF-beta) were quantified in all experimental days. There was no statistical difference between the groups analyzed considering the evaluated parameters. Therefore, at all implanted depths, PMMA behaved inertly in a murine model.No Level Assigned This journal requires that authors assign a level of evidence to each submission to which Evidence-Based Medicine rankings are applicable.

Abstract
This case series describes the soft tissue changes following extraction treatment in two patients with diverse lip thickness, but with similar baseline parameters including: labial competence, soft tissue profile, patient's age, extraction protocol, methods of anchorage, malocclusion, crowding, treatment appliance and mechanics. The same treatment plan involved upper first premolar extractions and lingual appliance combined with skeletal anchorage. The lip thickness played a crucial role in these cases, since a similar change of the incisor position leads to a different profile variation. This difference could be explained by the differing initial lip thicknesses as the patient with thin lips showed a more pronounced profilometric change. The choice of the ideal treatment plan must be tailored to the individual patient, taking into account not only initial skeletal and dental factors but also soft tissue factors, as well as the treatment goals.

Abstract
PURPOSE The aim of current study was to evaluate percentage root coverage (RC%) in isolated Miller class III/RT2 labial gingival recession (GR) associated with malaligned mandibular anteriors, using interdisciplinary periodontal-orthodontic treatment as compared to mucogingival surgery alone. METHODS Thirty-six systemically healthy patients having isolated Miller class III/RT2 GR with respect to malaligned mandibular anteriors, were randomly divided into test group: mucogingival surgery using subepithelial connective tissue graft followed by orthodontic treatment and control group: mucogingival surgery alone. Primary clinical parameters included (RC%), recession depth, keratinized tissue width, mid-labial clinical attachment level, interdental clinical attachment level (iCAL), periodontal phenotype (PP), gingival thickness (GT), root coverage esthetics score (RES) and hypersensitivity. Total duration of follow up was 12 months. RESULTS Mean RC% was significantly more achieved in test group (66.67%±40.82%) in comparison to control group (39.93%±31.41%) at the end of study (P=0.049). Further, complete root coverage was attained in 5/8 cases of test group versus 1/2 cases of control group after 3/12 months respectively. RES and hypersensitivity, showed statistically significant improvement after complete follow up period in both the groups. An ideal RES score of 10 was achieved in 4/7 cases of test group while in 1/2 cases of control group after 3/12 months respectively. Correlation analysis revealed significant negative correlation between RC% and iCAL. Correlation of RC% with GT and PP was non-significant. CONCLUSIONS Interdisciplinary periodontal-orthodontic approach may be more beneficial in terms of achieving improved RC%, esthetic and resolution of hypersensitivity in the management of Miller class III/RT2 GR in malaligned mandibular anteriors.

Abstract
PURPOSE This in vivo study aims to assess the pink esthetic score in the anterior maxilla after computer-guided immediate implant installation and fully digital immediate temporalization with and without grafting the jumping gap with a mixture of 1:1 autogenous and xenograft particulates. MATERIALS AND METHODS Twenty-four patients with non-restorable upper anterior teeth in the aesthetic zone have undergone a traumatic extraction for the non-restorable tooth followed by immediate implant placement using a 3D-printed surgical guide according to prosthetically driven implant placement. The patients were divided into two groups. The study group received the dental implant after grafting the jumping gap with 1:1 autogenous and xenograft particulates, while the control group received the dental implant without grafting the jumping gap. Each patient received a digitally fabricated, immediate, nonfunctional temporary prosthesis. The esthetic outcome was compared between the two groups using the pink esthetic score at implant insertion and after 6 months of follow-up. Statistical comparisons were carried out between the studied groups using the Mann-Whitney U test. RESULTS Immediately postoperatively, there was no statistically significant difference between the median PES in the two groups (P-value = 0.746). After six months, the study group showed a statistically significantly higher median PES than the control group (P-value = 0.048). CONCLUSIONS Grafting the jumping distance in the immediate implant protocol helps achieve a better esthetic outcome. CLINICAL RELEVANCE The use of immediate guided implant placement along with grafting the jumping gap followed by immediate digital temporalization guarantees a better esthetic outcome while preserving time, cost, and the number of clinical visits. TRIAL REGISTRATION The study was registered on clinicaltrials.gov with registration number NCT04096209. (19/9/2019).

Abstract
BACKGROUND Melanoma and non-melanoma skin cancer are significant causes of mortality. Previous studies regarding skin cancer education in nonmedical professionals have shown increases in favorable attitudes and likelihood of approaching clients about concerning lesions with training. However, few studies have investigated the use of estheticians in skin cancer screening. OBJECTIVES The objective of this study was to develop an education course to train estheticians to recognize concerning lesions, to assess the baseline knowledge of estheticians toward skin cancer detection, and to determine the effect that our curriculum has on lesion detection. METHODS We administered an education course and corresponding cross-sectional surveys to estheticians to evaluate current knowledge and assess for improvements in attitudes and behaviors regarding skin cancer detection. RESULTS Of 504 estheticians, most estheticians (85-98%) indicated the correct level of concern for "extremely concerning" lesions on pre- and post-training surveys. Estheticians were more likely to recommend that their client see a medical professional if they previously attended a course on skin cancer (p = 0.012) or had greater than 1 year of work experience (p < 0.001). After completion of the training module, most participants felt "very comfortable," suggesting that clients see a doctor for a suspicious lesion. CONCLUSION Our findings suggest that estheticians are capable of indicating the appropriate level of concern for abnormal lesions. Estheticians may serve as a valuable screening partner for dermatologists in the detection of skin cancer.

Abstract
Background Facial asymmetry is one reason orthodontic patients seek treatment. This study assessed the effect of mandibular asymmetry on facial esthetics and treatment needs perceived by laypersons, orthodontists, and maxillofacial surgeons. Materials and Method In this descriptive cross-sectional study, the frontal image of a model was captured and symmetrized from the facial midline using Adobe Photoshop software. The mandible was rotated 0°-8° with 1° intervals. Images were presented to 41 laypersons, 39 orthodontists, and 29 surgeons using an online questionnaire. The observers rated each image's esthetics with a 0-100 Visual Analog Scale and determined their treatment need by choosing one of the following three choices: No need for treatment, needs treatment, acceptable, but better to be treated. Analysis of variance for repeated measurements model. The regression method, Kruskal-Wallis analysis, was used for statistical analysis and the level of significance was set as P < 0.05. Results The images with 0° and 1° rotation received the highest esthetic rates among all three groups, while the images with 8° rotation were the least attractive ones. Furthermore, the image esthetic ratings significantly affected their treatment need. Mandibular asymmetry diagnosis threshold was 1° for orthodontists, and 3° for both laypersons and surgeons. The treatment need threshold was 5°, 6°, and 7° for surgeons, orthodontists, and laypersons, respectively. Conclusion The esthetics of images decreased when mandibular asymmetry increased. Treatment need was also related to increased asymmetry. Orthodontists were the most sensitive group in diagnosis, while surgeons were the most sensitive ones when it came to treatment.

Abstract
Discoloration poses a significant esthetic issue, and parents' opinions and emotional states may vary regarding different types of discoloration, such as molar incisor hypomineralization, caries or chromogenic bacteria. This study aimed to assess parent's emotional state and attitudes towards discoloration in primary and permanent teeth. A two-part questionnaire was designed, consisting of questions about demographic data and simulated visuals of different primary and permanent teeth discoloration conditions. The Visual Analog Scale (VAS) was used to determine the emotional state, while parents' attitudes towards dental consultation for each simulated visual were determined using statements such as "Absolutely yes"; "Yes"; "I don't have an idea"; "No"; "Absolutely no". The simulated visuals included cases of "caries with cavitation", "yellow-brown hypomineralized area", "white hypomineralized area" and "chromogenic bacteria". The questionnaire was distributed to 300 parents through online communication channels. Categorical variables were analyzed using Pearson chi-square, with statistical significance set as p < 0.05. A total of 230 parents completed the questionnaire. The highest VAS scores and the highest percentage of "Absolutely yes" responses were observed for "caries with cavitation" in both primary (77.8%, 81.7%) and permanent (60.4%, 94.3%) teeth. Additionally, statistically significant differences were found in the VAS scores for chromogenic bacteria (p = 0.04), caries with cavitation (p = 0.005), white hypomineralized area (p = 0.01) and yellow-brown hypomineralized area (p = 0.02). Comparatively, parental preferences showed statistically significant differences for chromogenic bacteria (p = 0.01), caries with cavitation (p = 0.01), yellow-brown hypomineralized area (p = 0.01) and white hypomineralized area (p = 0.004). Parents displayed stronger emotional responses towards "caries with cavitation" compared to hypomineralization and chromogenic bacteria discolorations and expressed a positive attitude towards seeking dental consultation.

Abstract
BACKGROUND Currently, safe practice in the UK esthetics industry is largely reliant on self-regulatory bodies. If these bodies do not maintain high standards of safety guidelines and properly accredit practitioners, patient safety may be at risk. To our knowledge, no studies have addressed cosmetic self-regulatory bodies and their websites on Google, the most commonly used information source. This study aimed to map self-regulatory bodies on Google and evaluate their roles in the current UK esthetics industry. METHOD We conducted a systematic search of Google Search results using eight search terms. The first 100 search results were screened against our eligibility criteria. We searched each website of a self-regulatory body for their requirements to join registers, membership fees, and features listed on the UK government's criteria for an effective self-regulatory body. RESULTS We identified 22 self-regulating bodies for the UK esthetics industry. Only 15% of registers required an in-person assessment of cosmetic skills to qualify for membership. Of the self-regulatory bodies, 65% did not set clear standards and guidelines for practice. No qualifications were required by 14% of surgical and 31% of non-surgical bodies. The mean membership fee was £331. CONCLUSION This study uncovered important information about the self-regulation of the esthetics industry in the UK. A significant majority of self-regulatory bodies did not meet best practices, potentially putting patients at risk. We recommend further studies screening a higher number of pages in a Google Search to scope all other existing self-regulatory bodies, due to the creation of Google "filter bubbles."

Abstract
BACKGROUND The aim of this study was to assess the esthetic perceptions of orthodontists, prosthodontists and laypersons with regard to different vertical positions of the maxillary central incisors related to lateral incisors for different facial vertical height cases. SUBJECT AND METHODS Frontal full-face photographs showing social smiles of three adult women aged between 18 and 25 years were used. Vertical position of the maxillary central incisor was changed (intruded or extruded) with 0.5 mm increments according to the reference gingival line resulting five images for each woman in a full-face view yielding a total of 15 images. A visual analog scale was placed below each smile to allow the raters to evaluate the attractiveness of each smile independently. One-way analysis of variance was used to determine whether there was a difference between more than two independent groups in terms of quantitative variables. Comparisons of more than two dependent groups were examined with repeated measures one-way ANOVA. The significance level was taken as 0.05 for all analyses. RESULTS For increased facial vertical height, the highest scores for orthodontists were given to the 0.5 mm extruded (64.18 ± 26.36), for prosthodontists to the control (57.28 ± 19.80), and for layperson to the 1 mm extruded (61.27 ± 25.98) central incisor position. For decreased facial vertical height, the highest scores were obtained at the 0.5 mm intrusion with an increasing pattern from orthodontists to laypersons (63.95 ± 22.08 for orthodontists, 79.87 ± 21.43 for prosthodontists, and 79.88 ± 19.17 for laypersons). All three rater groups gave the highest scores to the 0 mm (control) smile design for normal facial vertical height. When these scores were compared among the groups, laypersons gave significantly higher scores compared to orthodontists (p < 0.001) and prosthodontists (p = 0.005). CONCLUSIONS The facial vertical height significantly affected the perception of smile esthetics. Keeping the distance between the central and lateral incisors longer than 1 mm in individuals with increased facial height may be important in terms of increasing patient satisfaction in terms of clinical aesthetics. On the contrary, keeping the distance between the central and lateral incisors shorter than 1 mm may create a more esthetically acceptable result in individuals with short facial height.

Abstract
Background Human teeth and nails have demonstrated similar factors genetically, embryologically, and morphologically. The fingernail form may be used as a post-extraction guide for selecting the tooth form. Aim To evaluate the correlation between the maxillary left central incisor tooth form with the left index, middle, and ring fingernails in the Saudi Arabian population. Materials and Methods A descriptive cross-sectional study with purposive sampling was done among 200 Saudi participants. The maxillary left central incisor and the left index, middle, and ring fingernail were scanned using an intraoral scanner. The 3D digital images were converted to 3D models. The tooth form (tooth length, tooth width, and tooth shape) and nail form (nail length, nail width, and nail shape) were measured using the CAD software. Pearson's correlation coefficient and T-test were used for statistical analysis (P < 0.05). Result A significant correlation exists between tooth length and nail length, with a maximum correlation toward index nail length (P = 0.015). A significant correlation exists between tooth width and nail width, with a maximum correlation toward ring nail width (P = 0.002). A significant correlation exists between tooth length and nail length in females with a maximum correlation toward index nail length in females (P = 0.001). The mean percentage of similarity between tooth and nail shape (index, middle, and ring) in males and females shows a highly significant difference between them (P = 0.001). The results indicate that the tooth and nail shape are similar (70 to 90%) based on the criteria set by the software. Conclusion A definite correlation exists between maxillary central incisor tooth form and fingernail form. The fingernail form may be used as a post-extraction guide for selecting the maxillary central incisor tooth form in the Saudi Arabian population.

Abstract
PURPOSE The objective of this study was to compare patient-reported outcomes (PROs) of peri‑implant soft tissue inflammation and aesthetics around single-tooth implants in the anterior maxillary region with three different implant-abutment interface designs. METHODS Participants were randomized to one of three different types of implant-abutment interface designs [Conical (CI), flat-to-flat (FI), and Platform Switched (PS)]. Implants and provisional crowns with prefabricated titanium abutments were placed 5 months following extraction and/or ridge augmentation. Permanent ceramic crowns with zirconia abutments were placed after 12 weeks. To assess PROs, appearance and inflammation questionnaires were completed from provisional crown placement to the 3-year follow-up. RESULTS Tooth appearance at the 3-year follow-up revealed a difference amongst CI, FI and PS implants (p=0.049; Kruskal-Wallis test). PS was rated better than FI (p=0.047) at 1 year for appearance of soft-tissue and satisfaction with colour. There were no differences for self-consciousness, smile and pain/discomfort while eating/hard food items. CONCLUSIONS Although participants tended to rate the health of mucosa around PS implants as slighty better than the other two implant systems, the differences were minimal and inconsistent. Thus, patient satisfaction in terms self-perceived gingival health and esthetics was high for all 3 systems tested, suggesting that patients are unable to detect mucosal inflammation. CLINICAL SIGNIFICANCE Patients find it difficult to perceive mucosal inflammation; hence, it is recommended that patients attend implant follow-up visits, even if they do not perceive inflammation. The study suggests that there is a relationship between the PROs and the clinical outcomes of tested implants.

Abstract
Background Gingival recession is defined as the apical migration of gingival margin to the cementoenamel junction. Recently, amnion membrane, the third-generation membrane which is a placental-derived tissue, has been introduced. Materials and Methods Study included 45 subjects with age group of 20-60 years of both genders. Patients with Miller's Class I and Class II gingival recession were selected for the study. The progress was assessed at baseline one, three, and six months observation interval through clinical parameters RD, RW, PD, and CAL at the end of six months. Results Recession depths in the first, third, and sixth month were 1.82 ± 0.442, 1.31 ± 0.47 mm, and 0.91 ± 0.29, respectively, which showed a significant reduction from the baseline. Recession widths in the first, second, and third weeks were 3.04 ± 0.442 mm, 1.31 ± 0.47 mm, and 1.49 ± 0.59 mm, respectively. There was a statistically significant reduction (P > 0.005) when compared to the baseline. Pocket depths in the first, third, and sixth month were 0.93 ± 0.447, 0.42 ± 0.50, and 0.24 ± 0.43 (P > 0.005) which is significant when compared to baseline. Clinical attachment levels in the first, third, and sixth month were 2.73 ± 0.751, 1.78 ± 0.70, and 1.18 ± 0.53 (P > 0.005) which is significant compared to six months. Conclusion Within the limitations of the present study, the data obtained by periodic assessment of the clinical parameters indicate the use of amnion membrane and hyaluronic acid, and proper technique may thus be the panacea for root coverage procedure.

Abstract
Aim This study was conducted to observe and assess the dental and facial parameters of esthetics in children with healthy dentition and evaluate whether they are comparable to those of adults. Materials and methods An observational study included 70 children with ages ranging from 5 to 6 years who had come to the Department of Pediatric & Preventive Dentistry, Institute of Dental Studies & Technologies, Ghaziabad, Uttar Pradesh, India, with intact primary dentition. Standardized photographs of the children were taken and evaluated. Their facial and dental parameters were recorded and compared to that of those of adults. Result The relation of tooth and facial components was established, and it was found that they were not in the same proportion as those of adults. Conclusion The proportions of facial and dental parameters of esthetics of children at 6 years of age are different from those of adults. Clinical significance Since esthetic rehabilitation of primary teeth is becoming an important requisite of successful dental treatment, it is important to establish a standard guideline of dental and facial parameters for children for prosthetic rehabilitation.

Abstract
OBJECTIVES This study aimed to qualitatively and quantitatively assess the masking efficacy and color stability of resin infiltration on post-orthodontic ICL after 1 year. MATERIALS AND METHODS In 17 adolescents, 112 ICL (ICDAS-1: n = 1; ICDAS-2: n = 111) in 112 teeth were treated by resin infiltration (Icon, DMG) 3 to 12 months after bracket removal. The etching procedure was performed up to 3 times. Standardized digital images were taken before treatment (T0), 7 days (T7) and 12 months (T365) after treatment. Outcomes included the evaluation of the color differences between infiltrated and healthy enamel at T0, T7, and T365 by quantitative (colorimetric analysis (ΔE), ICDAS scores) and qualitative methods (5-point Likert scale (deteriorated (1), unchanged (2), improved, but not satisfying (3), improved and no further treatment required (4), completely masked (5)).) Differences between time points were analyzed by using Friedman test (ΔΕ) and chi-square tests (ICDAS). RESULTS The median color difference (25th/75th percentiles) between carious and healthy enamel at baseline (ΔΕ0) was 10.2(7.7/13.6). A significant decrease was observed 7 days after treatment (ΔΕ7 = 3.1(1.8/5.0); p < 0.001; ICDAS; p < 0.001). No significant changes based on ΔΕ (p = 1.000), and ICDAS grade (p = 0.305) were observed between T7 and T365 (ΔΕ12 = 3.4 (1.8/4.9)). Furthermore, at T365 four experienced dentists classified 55% and 39% of the lesions as "improved and no further treatment required" and "completely masked," respectively (Fleiss kappa: T365 = 0.851 (almost perfect)). CONCLUSION Resin infiltration efficaciously masked post-orthodontic ICL 7 days and 12 months after treatment. These results for most of the teeth could not only be observed by quantitative but also by qualitative analysis. CLINICAL RELEVANCE Resin infiltration efficaciously masks post-orthodontic initial carious lesions. The optical improvement can be observed directly after treatment and remains stable for at least 12 months.

Abstract
BACKGROUND Surgical incision designs are considered closely correlated to gingival papilla of dental implants. This study aims to explore whether different incision techniques for implant placement and second stage surgery affect gingival papilla height. METHODS Cases using different incision techniques (intrasulcular incisions or papilla sparing incisions) between November 2017 and December 2020 were selected and analyzed. A digital camera was used to capture images of gingival papilla at different time points. Ratio of papilla height to crown length using different incision techniques were measured and statistically compared. RESULTS A total of 115 papillae (68 patients) were eligible according to the inclusion/exclusion criteria. The average age was 39.6 years. Decreased postoperative papilla height were observed after implant placement surgery in all groups without statistical difference. However, for second stage surgery, intrasulcular incisions lead to more atrophy in gingival papilla compared to papilla sparing incisions. CONCLUSIONS Selection of incision techniques in implant placement surgery does not significantly affect papilla height. For second stage surgery, intrasulcular incisions significantly leads to more papilla atrophy compared with papilla sparing incisions. Trial registration KQCL2017003.

Abstract
Background Present study was performed to assess the biologic width relocation by performing aesthetic crown lengthening with the help of Chu aesthetic gauges. Methods The study included 192 teeth from 17 individuals, of which 64 teeth underwent crown lengthening (Treated site- TS) and 128 of which shared a proximal surface (Adjacent site -AS, Non-Adjacent site- NAS) with the surgery site. The clinical parameters Plaque index (PI), gingival index (GI), gingival margin position (PGM), relative attachment level (RAL), bone sounding (BS), biological width (BW), and probing depth (PD) were recorded. The clinical recordings were made at three different times: at baseline, 3 and 6 months post-operatively. Statistical analysis was performed using one way ANOVA and for pair wise comparisons post hoc Tukey test was used. Data was expressed in mean and standard deviations. P < 0.05 was considered statistically significant. Results PI and GI showed significant difference (p = 0.000*) at all time intervals. PGM and RAL were significant from baseline to 3 months, baseline to 6 months (p = 0.000*) while non-significance (p > 0.05) was recorded at 3-6 months comparison for PGM, RAL, BS, BW and PD. Conclusion Present study concluded that usage of Chu Aesthetic gauges help in controlled removal of soft and hard tissues, biologic width and gingival margin position got stabilized within 3 months and final prosthesis can be advised after 3 months of surgery.

Abstract
OBJECTIVES The aim of this study was to investigate differences in clinical and esthetic outcomes in the treatment of multiple gingival recession types 1 and 2, using the modified coronally advanced tunnel technique (MCAT) combined with subepithelial connective tissue graft (SCTG), with or without cross-linked hyaluronic acid (HA). MATERIALS AND METHODS A total of 24 patients with 266 multiple gingival recessions (GR) were enrolled in the study (133 recessions per group). MCAT was combined with SCTG and HA on the test side, while MCAT with SCTG was used on the control side. Clinical parameters were measured at baseline and 6 months post-operatively. Visual analogue scales (VAS) and questionnaires were used to assess patient-rated outcomes, and the root coverage esthetic score (RES) was used for professional esthetic evaluation. RESULTS No significant improvement in root coverage was observed as a result of adding HA. After 6 months, mean root coverage (MRC) was 85% for SCTG + HA group and 83% for SCTG group (p = 0.9819). Complete root coverage (CRC) was observed in 91% (test) and 93% (control) of the cases (p = 0.9001). Professional assessment of soft tissue texture (STT) using RES showed a significant difference (0.94 versus 0.69, p = 0.0219) in favor of the experimental group. CONCLUSIONS Both treatments were similarly effective in treating multiple GRs and led to comparable improvements in clinical parameters. However, application of HA improved the appearance of soft tissue texture. CLINICAL RELEVANCE Adjunctive application of HA in the MCAT + SCTG procedure may improve STT results.

Abstract
White spot lesions (WSLs) are sites of enamel surface and subsurface demineralization that increases tissue porosity and affects the teeth appearance. The resin infiltration technique proved to be a valid alternative to arrest caries lesion progression and to masking a color change in noncavitated WSLs. Thus, this study aims to report a clinical case of anterior WSLs treated with resin infiltration technique with an 8-year follow-up. The resin infiltration protocol was performed in an 18-year-old female patient presenting WSLs on the maxillary right lateral incisor, left central incisor, and left canine. The protocol followed the manufacturer's recommendations. The patient reported satisfaction with the smile appearance, at the end of the appointment. Infiltrated areas remained unchanged after an 8-year follow-up, showing an acceptable result for the patient's esthetic desires. After 8 years of evaluation, the resin infiltration technique proved to be a resistant and reliable alternative in preventing caries progression and in color masking WSLs.

Abstract
Background Facial aging is associated with the loss of soft tissue fullness. Perioral signs of facial aging can add years to individuals' appearances and even affect their facial expressions in smiling and nonsmiling images. Aims To evaluate the influence of the nasolabial fold on the visual perception of esthetics and age in the elderly, eye-tracking and a visual analog scale were used. Material and Methods This study applied a cross-sectional study using 40 laypeople. Facial images of an elderly woman were modified to include facial expression lines such as nasolabial folds and marionette lines with no folds, intermediate, and accentuated depths folds. Eye tracking was implemented to measure the average number of fixations. Heat maps and dot maps were generated using eye-tracking software. A visual analog scale of attractiveness and age perception questionnaire were also incorporated into the study. Statistical analysis was performed using a significance of (P<0.05). Results The majority of visual attention was paid to the eye and mouth areas. In the images with no folds, the right eye attracted a greater degree of fixation. In the images in which nasolabial folds were accentuated, the mouth area served as an area of high fixation. No statistical difference was observed between the groups in which smiling images were viewed. Nonsmiling images demonstrated significant differences between groups for variables including time until first fixation, complete fixation time, and number of fixations on the eyes and hemifaces. Old age and diminished attractiveness were associated with attenuated nasolabial folds, especially in nonsmiling images. Conclusion The facial lines and expressions of elderly female individuals were assessed by laypeople using eye-tracking, showing that the deeper one's nasolabial folds, the more aged and less attractive one appears, especially in nonsmiling images. Smiling pictures were perceived to be more attractive and youthful; these perceptions should be considered in the search for improved esthetic results, whether in dental or facial esthetic treatments.

Abstract
Background The study aimed to perform a cross-sectional comparative assessment of the content and quality of information available on the treatment of depression over websites in English and Hindi language. Materials and Methods We screened the first 50 links obtained on searching for depression treatment on Google, and selected 72 (44 in English; 28 in Hindi) websites. They were evaluated for coverage of different aspects of depression, quality of treatments mentioned, esthetics, and interactivity. Results A significantly lesser number of Hindi websites discussed the minimum duration of treatment needed for a depressive episode (36% vs. 79%), possible side effects of treatment (18% vs. 77%), discussed suicidality in depression explicitly (25% vs. 57%), or recommended consultation with a mental health professional (11% vs. 43%). English websites more commonly mentioned psychotherapy (86% vs. 64%), electroconvulsive therapy (64% vs. 21%), and social support measures (59% vs. 32%) for depression treatment. Whereas, Hindi websites more commonly mentioned Ayurvedic/herbal medicines (46% vs. 16%), and yoga (29% vs. 4%) for treatment. Lastly, the esthetics score for English websites was significantly higher than for Hindi websites. A significantly greater number of Hindi websites were owned by commercial entities. Conclusion This is the first study to systematically compare online information on depression treatment in English and Hindi language websites, and identify areas for further improvement in the overall quality of online information in Hindi. There is a need for the creation of credible and accessible online resources in regional languages like Hindi for the promotion of depression literacy among the general public by government and non-profit professional organizations.

Abstract
OBJECTIVE To evaluate the influence of Bichat's ball removal on postoperative inflammatory parameters (pain, edema, and trismus), facial volume reduction, facial esthetic satisfaction, and oral health-related quality of life. MATERIAL AND METHODS A single-arm clinical trial with 21 patients undergoing Bichat's ball removal. The following parameters were assessed at baseline and up to 3 months postoperatively: Visual Analogue Scale pain scores (0-10), rescue medication consumption, mouth opening, AM-Tr, AM-CEO, AM-NA, AM-CL, and AM-PM measurements, Oral Health Impact Profile (OHIP)-14 QoL scores, and satisfaction with facial esthetics (FACE-Q Satisfaction with Facial Appearance Overall Scale (SFAOS). X2, analysis of variance-repeated measures/Bonferroni, or Friedman/Dunn tests were used (p < 0.05, SPSS v20.0). RESULTS Peak pain occurred after 2 h and, 10 h later, the levels returned to baseline values (p < 0.001). Rescue medication consumption peaked in the first 24 h reducing significantly after 72 h (p < 0.001). Mean mouth opening decreased after 24 h and returned to baseline levels after 1 month, and all linear facial measures reduced significantly after 1 or 3 months (p < 0.05). OHIP-14 scores and FACE-Q SFAOS scores showed significant improvement after 1 month (p < 0.001), but patients aged > 25 years showed a significant reduction in FACE-Q SFAOS at the end of the study (p = 0.006). CONCLUSIONS Surgical removal of the Bichat's ball induces a mild inflammatory process controlled by rescue medication, significantly reduces face volume, and improves QoL and satisfaction with facial esthetics 3 months postoperatively. However, the efficacy of this procedure in patients > 25 years old is questionable. CLINICAL RELEVANCE Evaluate the effectiveness of bichectomy in terms of clinical effects and impact on quality of life.

Abstract
Background This study aimed to investigate whether the alignment of the teeth while smiling alters the visual perception by laypeople using eye tracking. Methods Facial images (two males and two females) were digitally edited to show a smile pattern with aligned teeth and one with crowded teeth. Sixty laypeople were selected to observe the images. The number of fixations, fixation duration, and time until the first fixation were recorded using an eye-tracking system. The results were qualitatively calculated with dot maps. Numerical data were analyzed using an independent Student's t test. Results There were no significant differences in fixation duration and the number of fixations in the crowded smile, mainly that of the male. The fixation times for the teeth were significantly different when the participants viewed the male subjects with a crowded smile (P<0.05). Dot maps showed greater attention to the smile with crowded teeth in both genders. Conclusion The crowded maxillary incisor smile attracted more visual attention to males from laypeople.

Abstract
PURPOSE Orbital epitheses replace a missing eyeball and surrounding soft tissue. Perception of epithesis in public gaze and the attention areas on the face are of interest. This study aimed to examine the differences in perception of orbital epitheses by prosthodontists, dentistry students, and laypeople with an objective evaluation tool that utilized eye-tracking technology. MATERIALS AND METHODS Twenty-four frontal facial images of 12 patients who had orbital epitheses were viewed by 81 observers (prosthodontists, dentistry students, laypeople) in random order for 5 seconds each. Gaze data were analyzed. Kruskal-Wallis H test with Bonferroni correction was used to compare parameters in groups and areas of interest. RESULTS First fixation duration at the mouth for symmetrical images were 0.30, 0.28, and 0.25 seconds for prosthodontists, students, and laypeople, respectively. Fixation duration at the mouth for the laypeople (0.27 second) was shorter than students (0.29 second) and prosthodontists (0.31 second) at symmetrical images. Time to the first fixation to epithesis, nose, and eye was significantly lower than the forehead and mouth for all groups. Fixation count at epithesis was 6.36 for prosthodontists, 5.64 for students, and 5.34 for laypeople. CONCLUSION Eyes were of most significant interest for all observer groups in symmetrical images. Individuals dealing with dentistry, especially prosthodontists, paid more attention to the mouth region along with the eyes in symmetrical images, considering fixation duration and fixation count. Attention directed to epithesis by all groups was verified with objective and measurable criteria. Prosthodontists' attention to epithesis and mouth was evident considering the four parameters measured.

Abstract
A goal of modern dentistry is to make an esthetic outcome as one of the major modalities in dental treatment. In recent years, more emphasis has been given to esthetic parameters, especially in the anterior regions. The aim of this study was to evaluate the presence of change in pink and white esthetics scores after giving crowns in a single tooth. Subjects for this retrospective study were chosen by randomization from June 2019 to May 2020. A total of 120 subjects were selected which were equally divided with respect to age and gender. The analysis was done with a photographic assessment. The study test was done using paired t-test, and the correlation was evaluated using the Chi-square test. In this study, we observed that there is an increase in pink and white esthetic scores (WES) after the prosthesis is delivered. There was a clinical and statistically significant difference seen with the WES and total score, whereas only clinical but no statistical difference was seen with the pink esthetic score. After giving crowns, there is an increase in overall esthetic score. It is important to have certain standardized indices to score esthetics by which the overall esthetic outcomes can be improved. One such popular index is the pink and white esthetic index, which scores the soft and hard tissue.

Abstract
Background and objectives Effective way to prevent mesial drift after the early loss of primary first molars is by inserting a durable space maintainer. Several space maintainers are available; fixed nonfunctional (FNF) space maintainer (crown and loop) is commonly used when abutment teeth need full-coronal restoration. Disadvantages of crown and loop space maintainer are nonfunctional, nonesthetic, and fracture of solder loop. To overcome this drawback, new design of fixed functional cantilever (FFC) space maintainer (crown and pontic) using bis-acrly composite resin. The study evaluated the longevity and acceptance of an FFC and compared it with a FNF space maintainer. Materials and methods A total of 20 healthy children, aged 6-9 years, were selected having bilateral premature loss of lower deciduous first molars. FFC space maintainer in one quadrant and FNF space maintainer in the other was cemented. The subject's acceptance of treatment was checked using a visual analog scale after the treatment completion. Criteria for complication leading to the failure was assessed in both the designs in the 3rd, 6th, and 9th month. Cumulative success longevity was obtained at a 9 month evaluation. Results Patient acceptability was greater in group I (FFC) in comparison to group II (FNF). In group I, fracture of the crown and pontic was the common complication leading to failure, followed by attrition of the crown and loss of material due to abrasion. In group II, fracture of the solder joint was the common complication leading to failure, followed by slippage of the loop gingivally and cement loss. The longevity of groups I and II were 70 and 85%, respectively. Conclusion FFC can be considered a viable alternative to conventional FNF space maintainers.

Abstract
BACKGROUND Lateral midface fractures occasionally require open reduction and internal fixation to restore function and facial symmetry. However, some patients retain facial asymmetry despite undergoing surgery due to hard tissue displacement or soft tissue sagging. This study aimed to determine the influence of soft tissue sagging on the postoperative facial symmetry. METHODS We examined the medical records of 590 patients who underwent planned plate removal after lateral midface or zygomatic bone fractures. After applying the inclusion and exclusion criteria, we analyzed 106 cases of lateral midface fractures for hard tissue displacement and soft tissue sagging using pre- and postoperative radiological imaging and postoperative face scanning. RESULTS We observed significantly larger soft tissue sagging (p < 0.001) and hard tissue displacement (p = 0.006) on the fractured side than on the non-fractured side. There was no correlation between differences in the soft tissue sagging and those in the hard tissue displacement (|rho|=0). Linear regression analysis showed no statistical influence of sex or age group on the soft tissue sagging and hard tissue displacement. CONCLUSION Therefore, we recommend treating soft tissue sagging as a discrete aspect of midfacial fracture treatment to achieve optimal postoperative facial symmetry. From a clinical perspective, we recommend better soft tissue management during open fracture treatment than focusing mainly on the reduction of bony hard tissues.

Abstract
Buccal fat pad removal or bichectomy is an esthetic surgical procedure that is gaining notoriety and increasing number worldwide. This paper aims to discuss the effectiveness of bandage in bichectomy postoperative concerning major complications like bleeding and subcutaneous emphysema. This is a retrospective case series according to PROCESS guidelines of 643 bichectomy surgeries performed by two different surgeons with the same technique from January 2018 until December 2020. Effectiveness of bandage is evaluated in complications rate decrease with statistical tests (p < 0.05). A literature review was performed to sediment knowledge about this theme. Female patients search for buccal fat pad removal more for esthetic reasons and male patients for functional purposes. Bichectomy has a low incidence of major complications, and this incidence decreases more with a bandage use (95%CI). Bandages are effective in the decrease of major complications related to bichectomy.

Abstract
OBJECTIVE A great number of patients are completely satisfied with a regular denture, on the other hand, numerous patients are still not satisfied with their denture functions despite proper denture manufacture in relation to prosthetic standards. AIM To estimate the parameters of satisfaction for patients to improve the health care quality of patients and evaluate the effect of the adaptation period. MATERIALS AND METHODS A total of 136 patients who participated in this study were patients with complete dentures (CD), after placement of the CD, the patients were asked some questions (about esthetics, phonetics, comfort, quality of fit, and the masticatory efficiency) and the satisfaction of patients was evaluated by using Likert's scale, then recorded four readings, first at the placement visit, second after 1 month, third after 45 days, and last after 2 months. RESULTS The female patients' satisfaction related to phonetics was about 37.8% at the placement visit, but about 91.2% after 2 months; the male patients' satisfaction related to phonetics was about 44% at the placement visit, then 94.6% after 2 months; the female patients' satisfaction as related to esthetics was about 56.6% at the placement visit, but was about 89.8% after 2 months; the male patients' satisfaction as related to esthetics was about 68% at the placement visit, but about 89.4% after 2 months. CONCLUSION The satisfaction of the patient with their CD is affected by many factors such as phonetics, esthetics, comfort levels, the quality of fitness of the denture, and the mastication. The differences between gender in satisfaction in all parameters were non-significant, that is, p > 0.001. The adaptation period has an effect on the satisfaction rate of the completely edentulous patient with their CD.

Abstract
OBJECTIVES The aim of this study is to analyze the esthetic perception of selected canine features, namely crown length, shade, inclination, and angle of incisal edge tip. MATERIALS AND METHODS The anterior maxillary teeth of a Central European woman were photographed and digitally modified in order to investigate esthetic perceptions of the above four categories. Three groups of examiners with different levels of experience in the field of dentistry (laypersons/inexperienced dental students, advanced dental students, dentists) evaluated the photographs twice with the help of visual analogue scales. RESULTS The best-evaluated canines have approximately the same length as the central incisor, have the same shade as the other anterior teeth, are best embedded in a lighter overall tooth shade, are neutral to slightly palatal inclined, and have a right angled to rounded incisal edge (≥ 90°). The canines evaluated as least esthetic, however, are longer than the central incisors, darker, inclined labially, and have a tapered incisal edge. No significant differences could be found between the evaluations of the groups with regard to the four feature categories. CONCLUSIONS Laypersons, advanced dental students, and dentists generally evaluate according to the same esthetic standards. Gender does not have a significant influence on evaluation. Clear definitions of esthetically favored shades, incisal edge shapes, inclination, and lengths of the canines can be given. CLINICAL RELEVANCE Since the esthetics of the smile line play a critical role for patients, dentists, dental technicians, and their supplying industry, knowledge of the esthetically preferred morphology of canines is essential. CLINICAL SIGNIFICANCE The aim of this study is to give clear definitions of esthetically favored shades, incisal edge shapes, and lengths of the canines, as the esthetics of the smile line play a critical role for patients, dentists, dental technicians, and their supplying industry (e.g., denture tooth manufacturers). Precise knowledge of esthetic preferences is important in clinical practice for both dentists and dental technicians, for example, in order to adequately advise patients regarding esthetic corrections. Also, in the case of missing teeth, this knowledge is essential for optimal and satisfactory restorations. Thus, this study can contribute to the satisfaction of general practitioners and patients.

Abstract
A common etiology of excessive gingival display is hypermobile upper lip, which can be managed by non-surgical and surgical approaches. Among the surgical options, lip repositioning surgery is a relatively simple procedure with minimal complications. Since the original description of the technique almost 50 years ago, several minor and major modifications have been introduced. The available evidence indicates that, when applied to properly diagnosed cases, the technique is effective in reducing gingival display and results in improved smile esthetics and high patient satisfaction. This article reviews the various techniques and modifications and summarizes the reported outcomes of the procedure.

Abstract
Formation of black triangles due to the loss of interdental papilla is one of the utmost perplexing esthetic problems of the periodontium. Many surgical and nonsurgical treatment options have been researched upon to obtain complete papillary fill, but minimally invasive procedures have always been the choice of treatment both for the operator as well as the patient. This article describes the use of injectable platelet-rich fibrin (i-PRF) as a novel nonsurgical technique for the reconstruction of deficient interdental papilla. This is probably the first article that describes the use of i-PRF for the nonsurgical treatment of black triangles. Six sites with the presence of deficient interdental papilla in four patients were selected for this case series. After completion and reevaluation of scaling and root planing, autologous i-PRF was injected at the base of the interdental papilla using the insulin syringe. Photographs obtained before the treatment and at 1, 3, and 6 months after the intervention were assessed by Image J software along with clinical measurements. The use of novel nonsurgical injectable PRF technique allows clinician to successfully treat deficient interdental papilla.
