Abstract
Linguoverted mandibular canine teeth (LMC) are a common cause of class 1 malocclusion, which may result in a traumatic occlusion. When deciduous LMC are diagnosed, extraction is commonly performed to alleviate traumatic occlusion. This retrospective study was designed to observe the outcome of the permanent dentition in dogs with a class 1 malocclusion receiving treatment for deciduous LMC. Medical records from a veterinary dental referral hospital were used to identify patients that underwent extraction of deciduous LMC's prior to the eruption of the permanent mandibular canine teeth. The permanent occlusion was then evaluated once the permanent mandibular canine teeth were erupting. Of the 28 dogs identified and treated for deciduous LMC's, 78.6% (22/28) had a normal permanent occlusion. The 6 patients identified with permanent LMC's were all diagnosed when the patients were between 20 and 29 weeks of age. Of these 6 patients, 5 received gingivectomy and gingivoplasty treatment to correct the permanent LMC. Treatment was declined by the pet owner of the sixth patient. Overall, the majority of dogs in this study with a class 1 malocclusion and deciduous LMC's treated with extractions prior to the eruption of the permanent mandibular canine teeth had a normal permanent occlusion.

Abstract
Background: Osteochondromas of the mandibular condyle show facial asymmetry and malocclusion. Because condylar osteochondromas are generally resected in a preauricular approach with risks of facial nerve injury and visible scar, the authors report endoscopically assisted intraoral resection of osteochondroma of the mandibular condyle with a piezoelectric surgical device.Case presentation: A 38-year-old woman presented with malocclusion and facial asymmetry caused by deviation of the chin to the left. Computed tomography showed a hyperdense, well-circumscribed mass arising from the medial aspect of the right mandibular condyle with resorption of the skull base. The patient underwent an endoscopically-assisted intraoral condylectomy with a piezoelectric surgical device. The postoperative course was uneventful without trismus, malocclusion, or facial asymmetry, and there was no recurrence 4 years after surgery.Conclusion:Endoscopically assisted intraoral resection of osteochondroma of the mandibular condyle with a piezoelectric surgical device is a minimally invasive and safe surgery.

Abstract
A fracture of the mandibular condyle is a common fracture of the mandible. After the diagnosis has been made, there are various treatment options: wait and see, conservative or surgical. Which of these treatment options is best depends on several different factors and is often the subject of debate. A common complication of a fracture of the mandibular condyle is malocclusion. Malocclusion can cause problems - even in the long term - for which the patient often requires secondary treatment.

Abstract
INTRODUCTION Orthodontic discrepancies are a common finding in patients with supernumerary teeth (ST). The presence of a ST can cause a number of orthodontic discrepancies, including delayed eruption or retention of adjacent teeth, crowding, spacing, and abnormal root formation. The aim of the present study was to assess the effect of extraction of an anterior supernumerary tooth on the underlying orthodontic discrepancies without additional treatment for a 6-month period. METHODS This was a prospective, longitudinal, observational, study. It included 40 participants with orthodontic malocclusions due to maxillary anterior supernumeraries. We examined the changes in the crowding and excessive space in the anterior and posterior segments on cast models. RESULTS In the group that presented with crowding, a statistically significant decrease of 0.95 ± 0.17 mm (P < 0.001) was found between T0 and T1. Of the participants, three exhibited full self-correction. The excessive space at T0 (3.06 mm) decreased by 1.78 ± 0.19 mm to T1 (1.28 mm) in the anterior segment. Seven participants showed full self-correction of the diastemas after the 6-month observation period. CONCLUSION The results imply that orthodontic treatment can be postponed for at least 6 months after the extraction of the supernumerary tooth as potential self-correction can be expected. This natural alleviation of the malocclusions may make the orthodontic treatment simpler, shorten the treatment time and decrease overall appliance wear time.

Abstract
Caudal malocclusions in cats may result in a variety of traumatic lesions affecting the soft tissues of the ipsilateral mandible such as fovea, gingival cleft, and proliferative lesions. Fifty-one cats diagnosed with a traumatic caudal malocclusion were compared with a control hospital population and evaluated for prevalence with respect to breed and sex. Twenty-two cats that were treated had radiographic, clinical findings, and the outcome of treatment (extraction or odontoplasty) recorded. Maine Coon, Persian, and male neutered cats were overrepresented while Domestic Shorthairs were underrepresented within the study population. Radiographically, 50% of the fovea lesions had an area of decreased bone density in the region of the lesion and none of these had evidence of periodontal disease. All gingival cleft lesions had radiographic changes consistent with periodontal disease. 15.4% of proliferative lesions presented with radiographic changes, with only half of those presenting with both radiographic and clinical evidence of periodontal disease. Eleven cats were treated by odontoplasty and eleven by extraction. One cat treated by odontoplasty developed new lesions caudally, and another had persistence of the initial lesions. Two cats in the extraction group developed new lesions rostral to the extracted teeth. In most instances, odontoplasty or extraction resulted in successful soft tissue lesion resolution. In rare cases, additional treatment was necessary due to either persistence or development of new lesions.

Abstract
The development of the craniomandibular system is guided by genetic interactions and environmental factors, including specific habits such as breastfeeding, bottle feeding, thumb sucking and the use of pacifiers. These habits can have a considerable impact on the growth of the developing jaws and can lead to malocclusion in children. This review aims to investigate potential associations between non-nutritive sucking habits (NNSHs) and malocclusions compared to the presence of nutritive sucking habits (NSHs). To carry out this systematic review, we followed the PRISMA protocol and performed a bibliographic search of the existing literature until April 2023 in the following electronic databases: Medline, PubMed, The Cochrane Library and Embase. Out of a total of 153 records, we included 21 studies. We found that the chances of diagnosing a malocclusion were higher for children with bottle nutrition when compared to breast-fed children. Breastfeeding provides protection against malocclusions. In the same manner, persistent NNSH habits appeared to be associated with increased chances of having malocclusions. The longer the child was breastfed, the shorter the duration of the pacifier habit and the lower the risk of developing moderate/severe malocclusions. The duration of the habits has a positive influence on the appearance of occlusion defects.

Abstract
INTRODUCTION This study performed a 3-dimensional analysis of tooth movement during orthodontic retention to assess the effectiveness of double retention (fixed and removable) in preventing undesired tooth movement. METHODS One hundred randomly selected patients were included at the initiation of double orthodontic retention with fixed retainers and vacuum-formed splints (recommended to be worn 22 h/d) in both arches. Intraoral scans were performed directly (T0), 1 month (n = 88), 3 months (T2) (n = 78), and 6 months (T3) (n = 66) after retainer bonding. Nine reference points were marked on each tooth in every patient. Subsequent scans were superimposed, and point displacement was calculated. Statistical analysis was performed using the R statistical software (version 4.2.2; R Core Team, Vienna, Austria). RESULTS Sample size calculation determined at least 55 patients were needed. The total dropout between T0 and T3 was 34 patients (did not show up for appointment). The median absolute displacement value of a single point between T0 and T3 was 0.015 mm. The most stable teeth were mandibular central incisors, whereas the least stable were mandibular molars. Most tooth displacements occurred between T0 and T2, then slowed down significantly. CONCLUSIONS Double orthodontic retention prevents major tooth displacements in most patients during the first 6 months of retention; however, larger, unpredictable single-tooth displacement may occur in individual patients.

Abstract
BACKGROUND Numerous studies have demonstrated a high likelihood of malocclusions resulting from non-nutritive sucking. Consequently, quantifying the impact of pacifiers can potentially aid in preventing the development or exacerbation of malocclusions and guide the design of improved performance pacifiers. METHODS This work proposes and assesses a computational methodology that can effectively gather crucial information and provide more precise data regarding the consequences of non-nutritive pacifier sucking. The computational framework utilized is based on solids4Foam [1, 2], a collection of numerical solvers developed within the OpenFOAM® computational library [3]. The computational model focuses on the palate of a six-month-old baby and incorporates various components such as palate tissues, pacifier and tongue, and considers the negative intraoral pressure generated and the tongue displacement. Different models were tested, each offering varying levels of detail in representing the palate structure. These models range from a simplified approach, with one tissue, to a more intricate representation, involving up to five different tissues, offering a more comprehensive palate model compared to existing literature. RESULTS The analysis of results involved examining the distribution of stress on the palate surface, as well as the displacement and forces exerted on the dental crowns. By comparing the obtained results, it was possible to evaluate the precision of the approaches previously described in the literature. The findings revealed that the predictions were less accurate when using the simplified model with a single tissue for the palate, which is the most common approach proposed in the literature. In contrast, the results demonstrated that the palate model with the most intricate structure, incorporating five different tissues, yielded distinct outcomes compared to all other combinations. CONCLUSIONS The computational methodology proposed, employing the most detailed palate model, has demonstrated its effectiveness and necessity in obtaining accurate data on the impact of non-nutritive sucking habits, which are recognized as a primary contributor to the development of dental malocclusions. In the future, this approach could be extended to conduct similar studies encompassing diverse pacifier designs, sizes, and age groups. This would foster the design of innovative pacifiers that mitigate the adverse effects of non-nutritive sucking on orofacial structures.

Abstract
BACKGROUND Nutritive sucking and nonnutritive sucking (NNS) may affect the craniofacial development, differently. AIM AND OBJECTIVES We investigated associations between NNS habits (NNSHs), developing malocclusion, and various feeding practices in 3-6-year-old children. METHODOLOGY A sample of 350 children 3-6-year-old from various preschools were selected for this case-control study (94 with NNSH and 256 without NNSH). NNSH (outcome) and feeding practices and developing malocclusions (exposures) were assessed using a structured study tool. RESULTS The prevalence of NNSH in 3-6-year-old children was 26.8%. The odds (95% [confidence interval (CI)]) of boys compared to girls having NNSH were 0.66 (0.4121-1.706) (P = 0.0290). The overall prevalence of developing malocclusion in 3-6-year-old children was 34.01% out of which open bite was most commonly reported with 12.57% followed by spacing 8.5%, increased overjet 6.8%, crowding 2.2%, posterior crossbite and rotation 1.4%, and overbite 1.14%. Breastfeeding was found to be the most commonly used mode of feeding reported by 53.42% of mothers. It was found that the odds (95% [CI]) of subjects having NNSH were 0.66 (0.4694-0.9460) (P < 0.0001) who were not breastfed as compared to those who were breastfed. Among developing malocclusions, increased overjet with P = 0.0019, open bite with P = 0.0416, and spacing with P = 0.0243 were found to be associated with feeding practices. CONCLUSION The prevalence of NNSH and developing malocclusions (increased overjet, open bite, and spacing) was 26.8% and 34.01%, respectively. Breastfeeding played a protective role against developing NNSH.

Abstract
BACKGROUND Panfacial bone fractures pose intricate challenges because of severe fragmentation and the loss of landmarks. Surgeons use a variety of reduction techniques, including bottom-up and top-down approaches. This single proportional meta-analysis explores sequencing differences and complications between oral and maxillofacial surgery surgeons (OMSs) and plastic and reconstructive surgeons (PRSs) in treating panfacial bone fractures. METHODS The PubMed and Scopus databases were searched systematically, and we compiled 14 studies published between 2007 and 2023 involving 1238 patients. A systematic review of the included studies was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, and data on the reduction techniques; total complication rates; and rates of malocclusion, enophthalmos, infection, asymmetry, and esthetic complications were collected. RESULTS The bottom-up technique was the most prevalent for both types of surgeons (57.1%, 8 out of 14). Malocclusion rates (I2 = 0% for OMSs and 41% for PRSs) were similar between the groups (p = 0.72), but PRSs tended to have a lower enophthalmos rate (I2 = 0% for OMSs and 32% for PRSs) than OMSs (p < 0.01). Infection rates remained consistent across all studies. However, high heterogeneity was observed for the total complication rate (I2 = 94% for OMSs and 85% for PRSs) and asymmetry and esthetic complications (I2 = 88% for OMSs and 92% for PRSs), making direct comparison between the two groups inconclusive. CONCLUSIONS In this study, the differences in surgical techniques and levels of interest have a greater impact on the outcomes of the panfacial bone fracture than the surgeon's specialty. However, more in-depth studies are needed to accurately pinpoint panfacial bone fracture reduction trends and differences in postoperative complications in the two expert groups.

Abstract
This report describes the successful treatment of an adult case of unilateral posterior crossbite caused by maxillary transverse deficiency with miniscrew-assisted rapid palatal expansion (MARPE). A female patient aged 35.5 years presented with masticatory disturbance, facial asymmetry, and unilateral posterior crossbite. She was diagnosed with unilateral posterior crossbite with a skeletal Class III jaw-base relationship and high mandibular plane angle. Her maxillary right and mandibular bilateral second premolars were congenitally absent, and the maxillary left second premolar was impacted. After the improvement of the posterior crossbite with MARPE, 0.018″ slot lingual brackets were placed on the maxillary and mandibular dentition. The total active treatment period was 22 months, and acceptable occlusion with a functional Class I relationship was achieved. Pretreatment and posttreatment cone-beam computed tomography images showed the disarticulation of the midpalatal suture after MARPE, and changes in the dental and nasomaxillary structures, nasal cavity, and pharyngeal airway. The case results demonstrate that MARPE produces greater skeletal expansion with minimal buccal tipping of the molars. MARPE may be effective for the treatment of maxillary transverse deficiency in adult patients.

Abstract
BACKGROUND A study is made of posterior crossbite in deciduous dentition and its possible association to extrinsic factors (bad oral habits). METHODS A total of 1168 Spanish children between 3 and 6 years of age were included in the study. Exploration of the oral cavity was performed to assess the presence of crossbite (uni- or bilateral and/or functional), and a questionnaire was administered to the parents or caregivers to determine the presence of bad oral habits and their duration. RESULTS In occlusion, 19.7% of the cases (n = 230) presented uni- or bilateral posterior crossbite. On adopting centric relation confronting the midlines, crossbite persisted in 165 children, indicating that 65 cases were due to premature contacts (functional crossbite). The identified favoring factors were pacifier use, thumb sucking, oral breathing and tongue thrusting or immature swallowing. DISCUSSION Most studies in the literature report a relationship between posterior crossbite and bad oral habits. The proportion of posterior crossbites identified in our study (16.6%) is consistent with the data published by authors such as Kobayashi, Limeira or Paolantonio, among others, but differs from the results of Zhifei Zhou, Peres or Germa. In coincidence with most studies, we recorded a statistically significant association between posterior crossbite and bad oral habits. CONCLUSIONS Bad oral habits favor the appearance of posterior crossbite, and the duration of the habit, its intensity (in the case of thumb sucking) and type (in the case of pacifier use) act as influencing factors. Functional study characterized the types of posterior crossbites and identified those attributable to premature contacts. This aspect has not been addressed by previous studies, and we consider the findings to be very interesting for analyzing and identifying the features of true crossbites.

Abstract
BACKGROUND Malocclusion is a multifactorial condition associated with genetic and environmental factors. The purpose of this study was to investigate the prevalence of occlusal traits, oral habits, and nose and throat conditions by age and to assess the association between malocclusion and its environmental factors in Japanese preschool children. METHODS A total of 503 Japanese children (258 boys and 245 girls aged 3-6 years) were recruited. Occlusal traits were assessed visually to record sagittal, vertical, and transverse malocclusion, and space discrepancies. Lip seal was recorded by an examiner, and oral habits (finger sucking, lip sucking or lip biting, nail biting, chin resting on a hand) and nose and throat conditions (tendency for nasal obstruction, allergic rhinitis, palatine tonsil hypertrophy) were assessed by a questionnaire completed by the parents. The prevalence of each item was calculated, and binary logistic regression was used to examine the factors related to malocclusion. RESULTS 62.0% of preschool children in the present study exhibited malocclusion, and 27.8% exhibited incompetent lip seal. Nail biting was the most frequent oral habit with a prevalence of 18.9%. Nasal obstruction was recorded in 30.4% of children. The results of binary logistic regression showed that incompetent lip seal was significantly related to malocclusion, and that nail biting was significantly negatively related. CONCLUSIONS Incompetent lip seal is significantly associated with malocclusion, but nail biting may not necessarily be a deleterious habit for the occlusion in Japanese preschool children.

Abstract
PURPOSE Using network meta-analyses (NMA) has become increasingly valuable as it enables the comparison of interventions that have not been directly compared in a clinical trial. To date, there has not been a NMA of randomized clinical trials (RCT) that compares all types of treatments for mandibular condylar process fractures (MCPFs). The aim of this NMA was to compare and rank all the available methods used in the treatment of MCPFs. METHODS Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, a systematic search was conducted in 3 major databases up to January 2023 to retrieve RCTs that compared various closed and open treatment methods for MCPFs. The predictor variable is treatment techniques: arch bars (ABs) + wire maxillomandibular fixation (MMF), rigid MMF with intermaxillary fixation screws, AB + functional therapy with elastic guidance (AB functional treatment), AB rigid MMF/functional treatment, single miniplate, double miniplate, lambda miniplate, rhomboid plate, and trapezoidal miniplate. Postoperative complications were the outcome variables and included occlusion, mobility, and pain, among other things. Risk ratio (RR) and standardized mean difference were calculated. Version 2 of the Cochrane risk-of-bias tool and Grading of Recommendations, Assessment, Development, and Evaluations system were used to determine the certainty of the results. RESULTS The NMA included a total of 10,259 patients from 29 RCTs. At ≤6 months, the NMA revealed that the use of 2-miniplates significantly reduced malocclusion compared to rigid MMF (RR = 2.93; confidence interval [CI]: 1.79 to 4.81; very low quality) and functional treatment (RR = 2.36; CI: 1.07 to 5.23; low quality).Further, at ≥6 months, 2-miniplates resulted in significantly lower malocclusion compared to rigid MMF with functional treatment (RR = 3.67; CI: 1.93 to 6.99; very low quality).Trapezoidal plate and AB functional treatment were ranked as the best options in 3-dimensional (3D) plates and closed groups, respectively.3D-miniplates (very low-quality evidence) were ranked as the most effective treatment for reducing postoperative malocclusion and improving mandibular functions after MCPFs, followed closely by double miniplates (moderate quality evidence). CONCLUSIONS This NMA found no substantial difference in functional outcomes between using 2-miniplates versus 3D-miniplates to treat MCPFs (low evidence).However, 2-miniplates led to better outcomes than closed treatment (moderate evidence).Additionally, 3D-miniplates produced better outcomes for lateral excursions, protrusive movements, and occlusion than closed treatment at ≤6 months (very low evidence).

Abstract
BACKGROUND Orthodontic treatment is a long process that requires patient cooperation. Risks of side effects such as caries formation, periodontal problems, and root resorption increases as well as problems in patient cooperation arises with longer treatments. Several different techniques were developed that may shorten the treatment time. OBJECTIVE The aim of this study was to evaluate the effectiveness of micro-osteoperforations (MOPs) performed during the alignment stage. TRIAL DESIGN Randomized controlled trial. METHODS Twenty-eight subjects who had crowding in the mandibular arch were included in the study. The first group (4 boys and 10 girls, mean age = 17.21 ± 3.76 years) was treated with MOP (MOP) and the second group (8 boys and 6 girls, mean age = 15.29 ± 1.77 years) was treated without MOP (control). Cephalometric variables, periodontal parameters, Little irregularity index, alignment duration, patient satisfaction, and ease of operation were evaluated. The level of statistical significance was P ≤ 0.05. RESULTS Alignment duration was shorter (P = 0.000) in the MOP group (105.57 ± 18.34 days) compared to control group (135.86 ± 15.12 days). Alleviating of the crowding was more in the MOP group, compared to the control group in all time points. The pain level in the MOP group in the first appointment was higher compared to control group (P = 0.002). There was no significant difference between the groups in cephalometric parameters. Higher increases were found for gingival index (P = 0.008) and bleeding index (P = 0.039) in the control group compared to MOP group at the end of treatment. LIMITATIONS The study was a single-centre study. CONCLUSION Alignment stage was shortened with MOP application. There was no difference between groups for patient satisfaction and pain level except for the first appointment. No difference was observed between the groups regarding cephalometric values. Clinically insignificant inflammation was observed in periodontal tissues for both groups. REGISTRATION This study was registered at the Clinical Trials Registry (ClinicalTrials.gov NCT03652454).

Abstract
BACKGROUND The application of orthodontic forces causes root resorption of variable severity with potentially severe clinical ramifications. OBJECTIVE To systematically review reports on the pathophysiological mechanisms of orthodontically induced inflammatory root resorption (OIIRR) and the associated risk factors based on in vitro, experimental, and in vivo studies. SEARCH METHODS We undertook an electronic search of four databases and a separate hand-search. SELECTION CRITERIA Studies reporting on the effect of orthodontic forces with/without the addition of potential risk factors on OIIRR, including (1) gene expression in in-vitro studies, the incidence root resorption in (2) animal studies, and (3) human studies. DATA COLLECTION AND ANALYSIS Potential hits underwent a two-step selection, data extraction, quality assessment, and systematic appraisal performed by duplicate examiners. RESULTS One hundred and eighteen articles met the eligibility criteria. Studies varied considerably in methodology, reporting of results, and variable risk of bias judgements.In summary, the variable evidence identified supports the notion that the application of orthodontic forces leads to (1) characteristic alterations of molecular expression profiles in vitro, (2) an increased rate of OIIRR in animal models, as well as (3) in human studies. Importantly, the additional presence of risk factors such as malocclusion, previous trauma, and medications like corticosteroids increased the severity of OIIRR, whilst other factors decreased its severity, including oral contraceptives, baicalin, and high caffeine. CONCLUSIONS Based on the systematically reviewed evidence, OIIRR seems to be an inevitable consequence of the application of orthodontic forces-with different risk factors modifying its severity. Our review has identified several molecular mechanisms that can help explain this link between orthodontic forces and OIIRR. Nevertheless, it must be noted that the available eligible literature was in part significantly confounded by bias and was characterized by substantial methodological heterogeneity, suggesting that the results of this systematic review should be interpreted with caution.

Abstract
BACKGROUND Clinicians agree that obtaining and retaining good treatment results for missing maxillary central incisors owing to trauma is not easy. Management of adult patients with permanent maxillary central incisor loss who visit the clinic with high expectations for aesthetics and function pose a significant diagnostic dilemma. Therefore, esthetic and functional outcomes should be taken into consideration when deciding the proper treatment method. The treatment described in this study aimed to reestablish smile esthetics by proposing an effective multidisciplinary clinical approach that includes orthodontic-prosthetic-periodontal procedures, optimally reduced lip protrusion, center dental midlines, and establishment of stable occlusion. CASE PRESENTATION The patient was a 19-year-old adult female with bimaxillary arch protrusion who had been wearing removable dentures for several years since the loss of her maxillary central permanent incisors. A multidisciplinary treatment including the extraction of two mandibular primary premolars was adopted. The treatment plan consisted of orthodontic space closure by shifting the adjacent teeth towards the central incisor spaces combined with appropriate morphologic remodeling and gingival reshaping to obtain good aesthetic and functional results. The duration to complete the orthodontic treatment was 35 months. Clinical and radiographic results after treatment suggested smile harmony with an improvement in the facial profile, good function of the occlusion, and a positive effect on bone remodeling in the area of the missing incisors during orthodontic tooth movement. CONCLUSIONS This clinical case illustrated the necessity for using multidisciplinary methods involving orthodontic, prosthodontic, and periodontic procedures to treat an adult female patient with bimaxillary arch protrusion and long-term absence of anterior teeth due to severe trauma.

Abstract
BACKGROUND Deviation from a normal bite can be defined as malocclusion. Orthodontic treatment takes 20 months on average to correct malocclusion. Accelerating the rate of tooth movement may help to reduce the duration of orthodontic treatment and associated unwanted effects including orthodontically induced inflammatory root resorption (OIIRR), demineralisation and reduced patient motivation and compliance. Several non-surgical adjuncts have been advocated with the aim of accelerating the rate of orthodontic tooth movement (OTM). OBJECTIVES: To assess the effect of non-surgical adjunctive interventions on the rate of orthodontic tooth movement and the overall duration of treatment. SEARCH METHODS An information specialist searched five bibliographic databases up to 6 September 2022 and used additional search methods to identify published, unpublished and ongoing studies. SELECTION CRITERIA We included randomised controlled trials (RCTs) of people receiving orthodontic treatment using fixed or removable appliances along with non-surgical adjunctive interventions to accelerate tooth movement. We excluded split-mouth studies and studies that involved people who were treated with orthognathic surgery, or who had cleft lip or palate, or other craniofacial syndromes or deformities. DATA COLLECTION AND ANALYSIS Two review authors were responsible for study selection, risk of bias assessment and data extraction; they carried out these tasks independently. Disagreements were resolved by discussion amongst the review team to reach consensus. MAIN RESULTS: We included 23 studies, none of which were rated as low risk of bias overall. We categorised the included studies as testing light vibrational forces or photobiomodulation, the latter including low level laser therapy and light emitting diode. The studies assessed non-surgical interventions added to fixed or removable orthodontic appliances compared to treatment without the adjunct. A total of 1027 participants (children and adults) were recruited with loss to follow-up ranging from 0% to 27% of the original samples. Certainty of the evidence For all comparisons and outcomes presented below, the certainty of the evidence is low to very low. Light vibrational forces Eleven studies assessed how applying light vibrational forces (LVF) affected orthodontic tooth movement (OTM). There was no evidence of a difference between the intervention and control groups for duration of orthodontic treatment (MD -0.61 months, 95% confidence interval (CI) -2.44 to 1.22; 2 studies, 77 participants); total number of orthodontic appliance adjustment visits (MD -0.32 visits, 95% CI -1.69 to 1.05; 2 studies, 77 participants); orthodontic tooth movement during the early alignment stage (reduction of lower incisor irregularity (LII)) at 4-6 weeks (MD 0.12 mm, 95% CI -1.77 to 2.01; 3 studies, 144 participants), or 10-16 weeks (MD -0.18 mm, 95% CI -1.20 to 0.83; 4 studies, 175 participants); rate of canine distalisation (MD -0.01 mm/month, 95% CI -0.20 to 0.18; 2 studies, 40 participants); or rate of OTM during en masse space closure (MD 0.10 mm per month, 95% CI -0.08 to 0.29; 2 studies, 81 participants). No evidence of a difference was found between LVF and control groups in rate of OTM when using removable orthodontic aligners. Nor did the studies show evidence of a difference between groups for our secondary outcomes, including patient perception of pain, patient-reported need for analgesics at different stages of treatment and harms or side effects. Photobiomodulation Ten studies assessed the effect of applying low level laser therapy (LLLT) on rate of OTM. We found that participants in the LLLT group had a statistically significantly shorter length of time for the teeth to align in the early stages of treatment (MD -50 days, 95% CI -58 to -42; 2 studies, 62 participants) and required fewer appointments (-2.3, 95% CI -2.5 to -2.0; 2 studies, 125 participants). There was no evidence of a difference between the LLLT and control groups in OTM when assessed as percentage reduction in LII in the first month of alignment (1.63%, 95% CI -2.60 to 5.86; 2 studies, 56 participants) or in the second month (percentage reduction MD 3.75%, 95% CI -1.74 to 9.24; 2 studies, 56 participants). However, LLLT resulted in an increase in OTM during the space closure stage in the maxillary arch (MD 0.18 mm/month, 95% CI 0.05 to 0.33; 1 study; 65 participants; very low level of certainty) and the mandibular arch (right side MD 0.16 mm/month, 95% CI 0.12 to 0.19; 1 study; 65 participants). In addition, LLLT resulted in an increased rate of OTM during maxillary canine retraction (MD 0.01 mm/month, 95% CI 0 to 0.02; 1 study, 37 participants). These findings were not clinically significant. The studies showed no evidence of a difference between groups for our secondary outcomes, including OIIRR, periodontal health and patient perception of pain at early stages of treatment. Two studies assessed the influence of applying light-emitting diode (LED) on OTM. Participants in the LED group required a significantly shorter time to align the mandibular arch compared to the control group (MD -24.50 days, 95% CI -42.45 to -6.55, 1 study, 34 participants). There is no evidence that LED application increased the rate of OTM during maxillary canine retraction (MD 0.01 mm/month, 95% CI 0 to 0.02; P = 0.28; 1 study, 39 participants ). In terms of secondary outcomes, one study assessed patient perception of pain and found no evidence of a difference between groups. AUTHORS' CONCLUSIONS: The evidence from randomised controlled trials concerning the effectiveness of non-surgical interventions to accelerate orthodontic treatment is of low to very low certainty. It suggests that there is no additional benefit of light vibrational forces or photobiomodulation for reducing the duration of orthodontic treatment. Although there may be a limited benefit from photobiomodulation application for accelerating discrete treatment phases, these results have to be interpreted with caution due to their questionable clinical significance. Further well-designed, rigorous RCTs with longer follow-up periods spanning from start to completion of orthodontic treatment are required to determine whether non-surgical interventions may reduce the duration of orthodontic treatment by a clinically significant amount, with minimal adverse effects.

Abstract
Infraocclusion is a local etiologic factor of malocclusion that can have deleterious effects on normal dental development. Therefore, early recognition and diagnosis are the two most important factors in the management of infraocclusion. The purpose of this case report is to describe the management of a patient who was diagnosed at seven years of age with an eruption disturbance, whose severe sequela could have been prevented had the infraocclusion been diagnosed early.

Abstract
The definition for a normal mandibular position in orthodontic regime includes two perspectives: an occlusion with maximum contacts with Class I inter-digitation, and an integrated relation between the components within temporomandibular joint (TMJ). Any displacement or deviation of the mandible from its normal position may result in anomalies in occlusion. Mandibular displacement can occur due to either physiological or pathological factors. The physiological deviation of the mandible at sagittal dimension is often caused by the phenomenon where the mandible moves forward or backward to coordinate and match the transverse width with the upper dentition. The physiological deviation of the mandible at transverse dimension, on the other hand, is mainly generated by the scenario where the mandible relocates its position to avoid some regional occlusal irregularities. The pathological deviation of the mandible at sagittal dimension is often taking place when condylar resorption progresses, leading the mandible to retrude backwards. Nevertheless, if the pathological degrading or hyperplasia of the condyles between two sides are unparalleled and asymmetrical, mandibular shift at transverse dimension would occur. The therapeutic restoration of the malpostioned mandible aims to relocate the deviated lower jaw into its relatively normal position, enabling a subsequent correction of the malocclusion. Bite registration and recording based on mandibular re-localization remain the vital and critical procedures in clinical practice. With the advent of clear aligner orthodontics, the clear versions of orthopedic modalities, namely, S8, S9 and S10, are specifically designed to alleviate mandibular displacement, therefore escalating the treatment efficacy by repositioning the mandible and correcting the individual teeth simultaneously. Condylar endochondral ossification triggered by mandibular repositioning not only consolidates the restorative posture of the mandible, but more importantly, repairs the deteriorating condyles and subsequently relieves temporomandibular disorder (TMD) conditions.

Abstract
BACKGROUND Autologous platelet-rich concentrates (PRCs) are recently used as a local biological substance in orthodontics to accelerate the rate of tooth movement. OBJECTIVES This systematic review aimed to evaluate the effects of PRCs on the rate of orthodontic tooth movement (OTM). SEARCH METHODS Unrestricted search of five electronic databases supplemented by the manual and gray literature search were undertaken in March 2022. SELECTION CRITERIA Randomized controlled trials (RCTs) evaluating the effect of PRCs on the rate of OTM with their side effect were included in this systematic review. DATA COLLECTION AND ANALYSIS Data items were extracted by two authors using a pre-piloted extraction form. Similar outcomes within a comparable time frame were synthesized in a meta-analysis. RESULTS Fourteen studies were deemed eligible for inclusion and seven RCTs were pooled in a meta-analysis. Canine retraction rate was higher in the side of PRCs injection than the control side by 0.28 mm/month (95% CI: 0.16-0.40, I2 = 95.6 per cent, P < 0.001, 345 patients) in the first 4 months after PRCs injection. There was no statistically significant difference between the PRCs side and the control side regarding molar anchorage loss (MAL) (MD = 0.03 mm, 95% CI: -0.18 to 0.24, I2 = 46.3 per cent, P = 0.78, 44 patients), canine rotation (MD = -0.19o, 95% CI: -1.95 to 1.57, I2 = 45.4 per cent, P = 0.96, 48 patients), or en-masse retraction. Likewise, there was no difference between both groups in terms of the duration of de-crowding. The mandibular canine retraction was statistically higher on the PRCs side than on the control side by 0.17 mm/month (P < 0.001, one trial). Regarding root resorption, there was no statistically significant difference between the experimental and control sides within the follow-up time. Mild pain scores were reported by the patients in the first 24 hours after injections. CONCLUSIONS Low-level evidence indicates that the effect of PRCs on OTM is minor and clinically insignificant. The findings should be interpreted with caution due to the inherent limitations in the included RCTs. REGISTRATION PROSPERO (CRD42022300026).

Abstract
Oral habits, such as mouth breathing, sucking, and lip and tongue habits, are important factors that lead to malocclusion. The abnormal pressure will disrupt the muscle balance of the oral and maxillofacial complex and interfere with the normal development of the maxillofacial complex. Therefore, early diagnosis and successful treatment of oral habits are pivotal to the early treatment of malocclusion. This paper discusses the malocclusion caused by children's oral habits and the corresponding intervention methods.

Abstract
OBJECTIVES To evaluate the relationship between dental malocclusion and speech to understand the etiology of speech sound disorders (SSD) in schoolchildren and to make a correct diagnosis and treatment plan. MATERIALS AND METHODS Articulation and dental occlusion, oromyofunctional evaluation with orofacial praxis and musculature, resting tongue position, and swallowing pattern were analyzed in 290 schoolchildren between the ages of 4 and 7 years. Statistical tests were considered significant for P < .05. RESULTS A significant association between dental malocclusions (Angle Class II and III, anterior open bite, edge-to-edge bite, overjet and anterior crossbite) and phonetic alterations (P = .008) was observed. Sigmatisms and rhotacisms were the most frequent disorders. Malocclusions also showed a significant association with oral habits and with orofacial praxis and muscle activity. CONCLUSIONS The presence of malocclusion can cause imbalances in the functions involved in the stomatognathic system. Awareness of this relationship in young children would help professionals to implement preventive measures for the optimum development of children's oral health.

Abstract
AIM Dental malocclusions present the third-highest prevalence among oral pathologies. The occlusion is evaluated in primary, mixed and permanent dentition. Most orthodontic patients are treated in the early permanent dentition. Early detection of dental anomalies is important to prevent complications and can have short- and long-term benefits. The aepidemiological data on the prevalence of malocclusion are an important determinant in planning appropriate orthodontic services. Dentists have the responsibility to recognise, diagnose, and treat or refer anomalies. Data from previous studies showed that the incidence of malocclusions expands from 11% to 93%. The aim of the study is to find out the prevalence and types of malocclusions in schoolchildren during four school years and how they were registered by four general dentists in their offices. METHODS The research was conducted over four consecutive school years during systematic examinations of schoolchildren from 1st to 9th grade. All primary schools (15 schools) in the area of Health Center Murska Sobota, Slovenia were included in the study. Dentists registered the presence and type of malocclusion. They prepared statistical data on the percentage of children with malocclusion and the percentage of represented malocclusion, as well as the statistical difference between genders. CONCLUSION There is a high percentage of malocclusion in 9th graders (15-year-old), about 50%, and a low number of children undergoing orthodontic therapy.

Abstract
Infraocclusion is a phenomenon that the relative occlusal growth of a tooth stops after the period of active eruption and then the tooth becomes depressed below the occlusal plane. Infraocclusion occurred more commonly in children and the mostly affected teeth were the primary mandibular second molars. The occlusal problem caused by infraocclusion may progressively worsen with age. This review summarizes the etiology, diagnosis and treatment of infraoccluded second primary molars, so as to provide reference for the dental clinicians.

Abstract
The effect of severely compromised teeth on masticatory function has not been properly evaluated in previous studies, as they were often considered equivalent to the healthy tooth or excluded as if absent in the dentition. Hopeless teeth, which refer to non-salvageable teeth that require extraction, can interfere with masticatory function. As posterior occlusion is directly related to the masticatory function, we evaluated pairs opposing posterior teeth (POPs) that reflect the arrangement as well as the number of remaining posterior teeth. This study investigated the relationship of a hopeless tooth to handgrip strength according to POPs in the elderly. This cross-sectional study used data from the Korea National Health and Nutrition Examination Survey (KNHANES). Among the data of 23,466 participants from 2015 to 2018, participants aged 60 years or older (n = 4,729) were included. In males with POPs scores of 0-7, considered poor posterior occlusion, the association with low handgrip strength persisted in the multivariate logistic regression model adjusted for all confounding variables. The odds ratio (OR) in the absence of hopeless teeth (OR = 1.91, 95% CI: 1.02-3.59) increased in the presence of a hopeless tooth (OR = 2.78, 95% CI: 1.42-5.47). Even with POPs scores of 8-11, considered good posterior occlusion, the association was significantly high in the presence of a hopeless tooth (OR = 2.82, 95% CI: 1.06-7.52). In females, the association disappeared in adjusted models. The fewer pairs of natural posterior teeth with occlusion, the greater the risk of low handgrip strength. Dentition containing hopeless teeth increases the risk of low handgrip strength, even in dentition with sufficient posterior occlusion. Preserving the posterior teeth in a healthy condition through personal oral hygiene and regular dental management is essential for maintaining components of physical function such as handgrip strength.

Abstract
The abnormal growth of the craniofacial bone leads to skeletal and dental defects, which result in the presence of malocclusions. Not all causes of malocclusion have been explained. In the development of skeletal abnormalities, attention is paid to general deficiencies, including of vitamin D3 (VD3), which causes rickets. Its chronic deficiency may contribute to skeletal malocclusion. The aim of the study was to assess the impact of VD3 deficiency on the development of malocclusions. The examination consisted of a medical interview, oral examination, an alginate impression and radiological imaging, orthodontic assessment, and taking a venous blood sample for VD3 level testing. In about 42.1% of patients, the presence of a skeletal defect was found, and in 46.5% of patients, dentoalveolar malocclusion. The most common defect was transverse constriction of the maxilla with a narrow upper arch (30.7%). The concentration of vitamin 25 (OH) D in the study group was on average 23.6 ± 10.5 (ng/mL). VD3 deficiency was found in 86 subjects (75.4%). Our research showed that VD3 deficiency could be one of an important factor influencing maxillary development. Patients had a greater risk of a narrowed upper arch (OR = 4.94), crowding (OR = 4.94) and crossbite (OR = 6.16). Thus, there was a link between the deficiency of this hormone and the underdevelopment of the maxilla.

Abstract
BACKGROUND The purpose of this systematic review was to analyze the available literature about the influence of breastfeeding in primary and mixed dentition on different types of malocclusions. METHODS Preferred Reporting Items for Systematic Reviews and Meta-Analyses Protocols (PRISMA-P) guidelines were used to perform the present review. The following electronic databases were searched: Pubmed, Evidence-Based Medicine Reviews (EBMR), Embase, Cochrane Library, Medline, Web of Science and Ovid. RESULTS A primary research found a total of 279 articles. Two more papers were also considered from the gray literature. Two hundred sixty-three articles were excluded as they were deemed irrelevant on the basis of: duplicates, title, abstract, methods and/or irrelevant contents. Eighteen papers were selected and included in the qualitative analysis. CONCLUSIONS breastfeeding is a positive factor that seems to reduce the incidence of posterior crossbite, skeletal class II and distoclusion in primary and mixed dentition. A sort of positive relationship between months of breastfeeding and risk reduction seems to exist. More longitudinal research is needed to avoid bias in the results, with data collected prospectively on the months of exclusive breastfeeding, by means of specific questionnaires and successive clinical evaluation of the occlusal condition at the primary dentition, mixed dentition and permanent dentition stages.

Abstract
Our study is based on the hypothesis that the prevalence of malocclusions in children is higher in the mining areas from North-Western (NW) Romania than in other geographic areas. We also considered that the distribution of the different types of malocclusions can be correlated with environmental factors. Therefore, the main purpose of the current study was to assess the prevalence of malocclusions in children from the mining areas in NW Romania. Another purpose was to establish the influence of certain environmental factors such as gender, geographical area of origin, and ethnicity on the distribution of malocclusions in order to provide an epidemiological reference for the planning of preventive and treatment programs adapted to the particularity of the mining areas. This cross-sectional study was performed in 2015-2016. The study batch consisted of 960 children from the mining areas, aged 7-14 years, in the period of mixed dentition and early permanent dentition. The clinical examination was conducted by a single examiner, an orthodontic specialist (TBI), in order to avoid inter-operator bias. Occlusion was registered according to Bjoerk. Occlusal clinical signs were followed for the determination of malocclusions. Most children had malocclusions (93.5%). The percentage of anomalies was significantly higher in subjects from Rosia Montana, in girls, and in the Romanians. Data showed that Angle Class I was the most prevalent malocclusion (60.21%), followed by crowding (47.5%), midline shift (43.33%), and deep bite (28.65%). The independent association between ethnicity and total malocclusions shows that the Romanian subjects presented a 3.31 higher chance of developing malocclusions than the Romani ones. The presence of malocclusions was independently influenced by all the studied environmental factors, namely gender, geographical area, and ethnicity. Our results could be relevant for oral health policy-making, i.e., planning preventive and treatment measures of malocclusions, adapted to the peculiarity of the studied mining areas.

Abstract
BACKGROUND Thalassaemia is a quantitative abnormality of haemoglobin caused by mutations in genes controlling production of alpha or beta globins. Abnormally unpaired globin chains cause haemolytic anaemia by causing membrane damage and cell death within organ systems and destruction of erythroid precursors in the bone marrow. The life-long management of the general health effects of thalassaemia in affected individuals is a highly challenging issue in and of itself; and failure to deal with dental and orthodontic complications in people with thalassaemia exacerbates the public health, financial and personal burden posed by the condition. There exists a lack of evidence-based guidelines for care-seekers and providers to best deal with such dental and orthodontic complications in thalassaemia, which this review seeks to address. OBJECTIVES The main objective of this review was to assess different methods to treat dental and orthodontic complications in people with thalassaemia. SEARCH METHODS We searched the Cochrane Cystic Fibrosis and Genetic Disorders Group's Haemoglobinopathies Trials Register, compiled from electronic database searches and handsearching of journals and conference abstract books. We searched the reference lists of relevant articles and reviews.Date of last search: 01 August 2019.We also searched nine online databases (PubMed, Google Scholar, ClinicalTrials.gov, WHO International Clinical Trials Registry Platform, Literature in the Health Sciences in Latin America and the Caribbean database, African Index Medicus, Index Medicus for South East Asia Region, Index Medicus for the Eastern Mediterranean Region, Indexing of Indian Medical Journals). We searched the reference lists of relevant articles and reviews and contacted haematologists, experts in fields of dentistry, organizations, pharmaceutical companies and researchers working in this field.Date of last search: 22 July 2019. SELECTION CRITERIA We searched for published or unpublished randomised controlled trials for treatment of dental and orthodontic complications in individuals diagnosed with thalassaemia, irrespective of phenotype, severity, age, gender and ethnic origin. DATA COLLECTION AND ANALYSIS Two review authors independently screened 35,202 titles from search results. We identified four unique randomised controlled trials, of which one seemed potentially relevant. Based on closer inspection, the trial was found not to be eligible for inclusion. MAIN RESULTS We did not find any relevant trials for inclusion in the review. AUTHORS' CONCLUSIONS We were unable to draw any conclusions due to the lack of available data and trials. This review highlights the need for conducting and appropriate reporting, of high-quality randomised controlled trials investigating the effectiveness of various treatment modalities for dental and orthodontic complications in people with thalassaemia.

Abstract
The aim of this study was to determine the differences in arch length, inter-canine distance, inter-premolar distance, intermolar distance and arch shape between dental discrepancies (crowding and spacing) in a sample of dental casts from the Afro-Colombian population of San Basilio de Palenque. An analytical, cross-sectional study was conducted on a convenience sample of 63 subjects aged 11 to 57years, of Afro-Colombian origin, with full dentition from first molar to first molar, without extensive caries or restorations, and excluding casts with defects due to loss. The differences between arch (upper and lower) variables were analyzed according to dental discrepancies. Plaster models digitalized with a TR1OS3 Mono scanner with exactitude (6.9 ± 0.9 pm) and precision (4.5 ± 0.9 pm) were analyzed with Orthonalyzer software. Statistical analyses were done on SPSS software (Version 20 for Windows) and Real Statistics. Spacing discrepancy of68.25% was found for upper arch and 66.66% for lower arch; crowding discrepancy of 19.04% for upper arch and 20.63% for lower arch, and an adequate ratio of 12.69% for both arches. No statistically significant difference (p>0.05) was found between arch parameters except for inter-premolar distance on the lower arch. The most frequent arch shape in the population was oval for both upper arch, with 76.19%, and lower arch, with 71.42%. Tooth size was larger in males than females but the difference was not statistically significant.

Abstract
Interceptive orthodontics is intended to optimize dentofacial growth and development. This treatment concept attempts to prevent or minimize dental development abnormalities while enabling craniofacial growth modification. Utilizing preventative holistic concepts, it also focuses on habit intervention. Interceptive orthodontics in children entails monitoring for a variety of conditions, including excessive space, severe crowding, open or deep bites, anterior and/or posterior crossbites, severe overjet, and abnormal eruption patterns. This article will review the etiologies of these clinical presentations, categorizing them into three groupings: abnormalities in development, craniofacial growth alterations, and oral habits. The prevention of orthodontic issues also will be discussed.

Abstract
Radicular cysts arising from primary teeth are uncommon and, when present as large lesions, may adversely affect the underlying permanent teeth. The purpose of this paper is to describe the management of a very large atypical radicular cyst involving the primary dentition of a nine-year-old boy and causing extensive tooth displacement with transposition of the permanent maxillary left canine between the bicuspids. The root apex of the canine was close to the median level of the lateral border of the nasal cavity and showed incomplete root formation and signs of dilacerations in its apical third. Marsupialization was successfully performed, followed by long-term orthodontic treatment. This interdisciplinary management facilitated the lesion resolution for repositioning of the canine into functional occlusion.

Abstract
Malocclusion is a worldwide dental problem that influences the affected individuals to varying degrees. Many factors contribute to the anomaly in dentition, including hereditary and environmental aspects. Dental caries, pulpal and periapical lesions, dental trauma, abnormality of development, and oral habits are most common dental diseases in children that strongly relate to malocclusion. Management of oral health in the early childhood stage is carried out in clinic work of pediatric dentistry to minimize the unwanted effect of these diseases on dentition. This article highlights these diseases and their impacts on malocclusion in sequence. Prevention, treatment, and management of these conditions are also illustrated in order to achieve successful oral health for children and adolescents, even for their adult stage.

Abstract
Objective: To assess the validity of the 5-year index by subjecting study models at the age of 5 years to both the 5-year index and the Goslon yardstick, and then relating these results to the Goslon ratings at 10 years. Design: Retrospective study. Setting: Sahlgrenska University Hospital, Gothenburg, Sweden. Patients: Study models of 94 patients with unilateral cleft lip and palate (UCLP) were evaluated at the ages of 5 and 10 years. The dental arch relationships were judged and categorized by using the Goslon yardstick for the 10-year models and both the Goslon yardstick and the 5-year index for the 5-year models. Results: When used for 5- and 10-year models, the Goslon yardstick showed a kappa score of 0.539 (weighted kappa = 0.579) with a moderate strength of agreement. However, 5-year index scores at 5 years compared with the Goslon scores at 10 years showed a kappa score of only 0.043 (weighted kappa = 0.090), showing poor strength of agreement. Goslon scores at 10 years showed improvement in 14 cases when graded by the same Goslon yardstick at 5 years, whereas there was improvement in 23 cases when the 5-year models were graded by the 5-year index (actual improvement in scores in UCLP cases is highly unlikely). Conclusions: Although use of the Goslon yardstick at 5 years has demonstrated some inherent flaws in its use at that age, these drawbacks are fewer than those when the 5-year index is used at 5 years of age.

Abstract
Objective: To evaluate the dental arch relationships for a consecutive series from Goteborg, Sweden, who had delayed hard palate closure. Design: Retrospective study. Setting: Sahlgrenska University Hospital, Goteborg, Sweden. Patients: The dental study models of 104 consecutive unilateral cleft lip and palate subjects. The study cohort was born between 1979 and 1994. Longitudinal records were available at ages 5 (n = 94), 10 (n = 97), 16 (n = 59), and 19 years (n = 46). Five assessors rated models according to the GOSLON Yardstick on two separate occasions each. Interventions: These patients had been operated upon according to the Goteborg protocol of delayed hard palate closure (at age 8 years). Results: 85% of subjects were rated in groups 1 and 2 (excellent or very good outcome), 12% were rated in group 3 (satisfactory), and 3% were assigned to group 4 (poor). No patients presented in Group 5 (very poor). Weighted kappa statistics for double determination of Yardstick allocation for five assessors demonstrated values between .65 and .90 for interrater agreement (good/very good) and between .70 and .90 for intrarater agreement (very good). Conclusions: Delayed hard palate closure as practiced in Goteborg since 1979 has produced the best GOSLON Yardstick ratings in a consecutive series of patients ever recorded worldwide, since the Yardstick was first used in 1983. However, it is noteworthy that a new protocol has been introduced in Goteborg since 1994, in which hard palate closure is done at 3 years due to concerns regarding speech.

Abstract
Objective Evaluation of the effect of infant orthopedics (IO) on the occlusion of the deciduous dentition in patients with unilateral cleft lip and palate (UCLP). Design Prospective, two-arm, randomized, controlled clinical trial with three participating cleft palate centers (Dutchcleft). Setting Cleft Palate Centers of the University Medical Center Nijmegen, Academic Center of Dentistry Amsterdam, and Dijkzigt University Hospital Rotterdam, The Netherlands. Patients Children with complete UCLP (n = 54) were included. Interventions In a concealed allocation procedure, half of the patients was randomized to wear a plate till surgical closure of the soft palate (IO+), and the other half (IO−) did not have a plate. Mean Outcome Measures Dental arch relationships were assessed at 4 and 6 years of age with the 5-year-old index; the Huddart-score; and measurements of overjet, overbite, and sagittal occlusion. Results There were no significant differences found between the IO+ and IO− groups for the 5-year-old index; the Huddart-score; and overjet, overbite, and sagittal occlusion. Conclusions IO had no observable effect on the occlusion in the deciduous dentition at 4 and 6 years of age. Considering the occlusion only, there is no need to perform IO in children with UCLP.

Abstract
Objective To compare dental arch relationships up to age 17 in individuals with complete unilateral cleft lip and palate (UCLP) treated at five European centers. Design Longitudinal cohort study, where results were previously reported at 9 years and follow-up measurements were obtained for 12 and 17 years. Setting Multidisciplinary cleft services in Northern Europe. Subjects 127 consecutively treated individuals with repaired UCLP. Main outcome measure Panel rating of dental arch relationship. Results The results revealed that at 17 years of age three of the centers had better ratings in dental arch relationship (means scores: 1.7, 1.9, and 2.2, respectively) than the other two centers (3.3, 3.4) at statistically significant levels (p < .01 to p < .001). Conclusion The results confirm that systematic differences in dental arch relationships may occur between different cleft centers, but do not allow specific causal factors to be identified.

Abstract
Objective To evaluate dental arch relationships and dimensions, relative to an age matched noncleft sample, in Caucasian 3-year-old children with repaired unilateral cleft lip (UCL) or unilateral cleft lip and palate (UCLP). Design Prospective, cross-sectional, case-control study performed in Scotland, U.K. Participants Eleven children with repaired unilateral cleft lip, 16 children with repaired unilateral cleft lip and palate, and 78 children as controls. Main Outcome Measures Dental arch relationships and linear arch dimensions. Results Prevalence of Class III incisor relationship was 31.3% in children with unilateral cleft lip and palate compared with 9.1% in children with unilateral cleft lip. A buccal crossbite was present in 36% of children with unilateral cleft lip, compared with 75.6% of children with unilateral cleft lip and palate. Mean linear maxillary arch dimensions did not differ significantly between children with unilateral cleft lip and the controls. Except for second intermolar width, statistically significant differences existed in mean linear maxillary arch dimensions between the unilateral cleft lip and the unilateral cleft lip and palate groups; the mean linear maxillary arch dimensions were significantly greater in the control group than in the unilateral cleft lip and palate group. The mean cleft-affected anterior quadrant length appeared to be the arch dimension with the greatest power of discrimination among the three groups. There were no significant differences in mean linear mandibular arch dimensions among the three groups. Conclusions Anterior crossbite was almost three times more common in the unilateral cleft lip and palate group than in the unilateral cleft lip group. Mean linear maxillary arch dimensions differed significantly between the unilateral cleft lip and palate group and the control group. There were no significant differences in mean linear maxillary arch dimensions between unilateral cleft lip and controls or between mean linear mandibular arch dimensions for unilateral cleft lip, unilateral cleft lip and palate, and controls.

Abstract
Objective The treatment of a patient with a complete unilateral left cleft lip and palate, agenesis of the left upper second premolar, and a severely malformed left upper lateral incisor is reported. Treatment included placement of an autologous bone graft from the left iliac crest into the alveolar cleft at 8 years of age and transplantation of a lower premolar into the reconstructed alveolar process at 10 years of age. During the succeeding orthodontic treatment, the dental arches were aligned and corrected toward a Class I molar occlusion. One year after the end of treatment, the status of the transplanted premolar was good.

Abstract
Objective Unfortunately, not all patients receive the benefits of a well-trained, experienced, multidisciplinary cleft team, and a significant number of patients reach adulthood with severe neglected cleft related problems. The vast majority of this group have made their way through several surgical procedures, usually performed by different surgeons in different centers, and still carry the original cleft stigmata aggravated by variable degrees of maxillary hypoplasia, fistulae, scarring, muscle pull, soft tissue tension, lost teeth, dental adaptation, and instability of bony fragments. Adult patients who reach this stage with their original deformities have, in most instances, lost their best opportunity to be properly treated. With this assumption in mind, an aggressive surgical plan focused mainly on the deformities that can objectively achieve functional and aesthetical improvement should be individualized for each patient. In this article, experience with 38 consecutive adult patients with cleft managed following a two-stage protocol used at our cleft clinic for the last 4 years is presented. Conclusion An algorithm to help definitively solve these deformities is suggested.

Abstract
OBJECTIVES To evaluate prevalence, distribution, and sexual dimorphism of dental anomalies (DA) among different skeletal malocclusions (SM) and growth patterns (GP) under the hypothesis that specific clinical patterns exist and may indicate common etiological roots. MATERIALS AND METHODS A total of 1047 orthodontic records of patients older than 8 years were evaluated. The SN-GoGn angle was used to classify GP (hypodivergent, normal, and hyperdivergent), and the ANB angle was used to verify SM (Angle Classes I, II, and III). These assessments were done from lateral cephalometric radiographs. DA were diagnosed using panoramic radiographs by one calibrated investigator. Odds ratios, chi-square, and Student's t-tests were used. RESULTS Of the subjects, 56.7% were female, with mean age of 16.41 (±10.61) years. The prevalence of DA was 15.7%. Impaction and tooth agenesis were the most prevalent DA, with relative frequencies of 14.4% and 9.7%, respectively. DA were most prevalent in Class III SM (80.8%) and in hypodivergent GP (82.5%), although this was not statistically significant. Tooth agenesis ( P < .01) and microdontia ( P = .025) were significantly more common among hypodivergent GP and Class III SM, respectively. CONCLUSIONS The results of this study support the idea that DA are preferentially associated with certain patterns of malocclusion.

Abstract
INTRODUCTION The present study analyzed the characteristics of malocclusions, occlusal traits among Special Health care Needs (SHCN) children with Down syndrome (DS) and autism disorder (AD) in Riyadh City, Kingdom of Saudi Arabia. MATERIALS AND METHODS A total of 100 DS and 100 AD children from five rehabilitation centers in and around Riyadh, Kingdom of Saudi Arabia, were included in the study. Any children with history of ongoing medical treatment, extraction, or orthodontic treatment were excluded from the study. Out of the 200 patients examined, 131 were males and 69 were females and the age of the children ranged from 6 to 14 years. The children were examined for malocclusion characteristics using the Angle's classification of malocclusion, and also other occlusal traits, such as overjet, overbite, cross bite, and open bite were also determined. The data obtained were analyzed using Statistical Package for the Social Sciences, version 16 to generate descriptive statistics for each variable. RESULTS The analyzed data of the right and left permanent molar relation showed higher incidence of class III malocclusion (66%) in DS children as compared with (3-4%) AD children. The AD children presented with higher percentage of class I malocclu-sion (40-41%) as compared with (10-14%) DS children. During examination of the primary molars, the analyzed data showed that left primary molar had more mesial shift in AD children as compared with DS children. CONCLUSION Down syndrome children had high incidence of class III malocclusion and autistic children had high incidence of class I malocclusion. Overall, the DS children were more prone to malocclusion. CLINICAL SIGNIFICANCE This study provides database for health professionals in Saudi Arabia in regard to malocclusion of autis-tics and DS patients.

Abstract
The aim of this systematic review and meta-analysis was to examine the current evidence on the possible effects of breastfeeding on different malocclusion traits in primary and mixed dentition. A systematic search was made in three databases, using terms related to breastfeeding and malocclusion in primary and mixed dentition. Of the 31 articles that met the inclusion criteria and were included in the qualitative analysis, nine were included in the quantitative analysis. The quality of the 31 observational studies was moderate to high on the Newcastle-Ottawa Scale. It was found that the odds ratio for the risk of posterior crossbite was 3.76 (95% CI 2.01-7.03) on comparing children who had not been breastfed, with those breastfed for over six months, and rose to 8.78 (95% CI 1.67-46.1) when those not breastfed were compared to those breastfed for over twelve months. The odds ratio for class II malocclusion in children breastfed for up to six months compared to those breastfed for over six months was 1.25 (95% CI 1.01-1.55). Lastly, children who were breastfed for up to six months had an odds ratio of 1.73 (95% CI 1.35-2.22) for non-spaced dentition compared to those who were breastfed for over six months.
