J World Fed Orthod 2024; 13:72-77. [PMID: 37985293 DOI: 10.1016/j.ejwf.2023.10.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2023] [Revised: 10/27/2023] [Accepted: 10/27/2023] [Indexed: 11/22/2023]
Abstract
OBJECTIVES The aim of this study was to assess subjectively and objectively, at which timepoint the patient undergoing fixed orthodontic treatment will have maximum pain during the initiation of orthodontic treatment. MATERIALS AND METHOD A total of 22 patients (21 ± 2.7 years, [15 female and 7 male]) requiring extraction of maxillary first premolar participated in the study. Following bonding, an initial archwire of 0.016" NiTi was placed with a distal force of 100 g applied to the canines. The concentration of prostaglandin E2 (PGE2) in the gingival crevicular fluid was assessed at four time points: 1 hour before (T0); 24 hours (T1); 48 hours (T2); 72 hours (T3) after initial archwire placement. The pain intensity was recorded with visual analog scale. RESULTS The concentration of PGE2 increased from T0 to T1. The highest concentration was observed at T2 following which there was a mild decline at T3. Statistically significant difference in the PGE2 concentration was observed between T0 to T1 and T1 to T2. The visual analogue scale (VAS) scores increased from T0 to T1. The highest score was observed at T2 followed by a decline at T3. A statistically significant difference in the VAS score was noted between T0 to T1 and T2 to T3. On correlating PGE2 and VAS score, a weak negative correlation was noted between T0 to T1 and no correlation was noted between T1 to T2 and T2 to T3. CONCLUSION The patients experience maximum pain between 24 hours (T1) and 48 hours (T2) following initial archwire placement. The highest concentration of PGE2 and VAS score was observed at 48 hours (T2).

Abstract
Multiple sclerosis is a chronic inflammatory disease that affects the central nervous system and can cause various types of pain including ongoing extremity pain, Lhermitte's phenomenon, trigeminal neuralgia, and mixed pain. Neuropathic pain is a major concern for individuals with multiple sclerosis as it is directly linked to myelin damage in the central nervous system and the management of neuropathic pain in multiple sclerosis is challenging as the options available have limited efficacy and can cause unpleasant side effects. The literature search was conducted across two databases, PubMed, and Google Scholar. Eligible studies included clinical trials, observational studies, meta-analyses, systematic reviews, and narrative reviews. The objective of this article is to provide an overview of literature on pharmacological and non-pharmacological strategies employed in the management of neuropathic pain in multiple sclerosis. Pharmacological options include cannabinoids, muscle relaxants (tizanidine, baclofen, dantrolene), anticonvulsants (benzodiazepines, gabapentin, phenytoin, carbamazepine, lamotrigine), antidepressants (duloxetine, venlafaxine, tricyclic antidepressants), opioids (naltrexone), and botulinum toxin variants, which have evidence from various clinical trials. Non-pharmacological approaches for trigeminal neuralgia may include neurosurgical methods. Non-invasive methods, physical therapy, and psychotherapy (cognitive behavioral therapy, acceptance and commitment therapy and mindfulness-based stress reduction) may be recommended for patients with neuropathic pain in multiple sclerosis. The choice of treatment depends on the severity and type of pain as well as other factors, such as patient preferences and comorbidities. There is a pressing need for healthcare professionals and researchers to prioritize the development of better strategies for managing multiple sclerosis-induced neuropathic pain.

Wang S, Ko CC, Chung MK. Nociceptor mechanisms underlying pain and bone remodeling via orthodontic forces: toward no pain, big gain. FRONTIERS IN PAIN RESEARCH 2024; 5:1365194. [PMID: 38455874 PMCID: PMC10917994 DOI: 10.3389/fpain.2024.1365194] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/03/2024] [Accepted: 02/12/2024] [Indexed: 03/09/2024] Open
Abstract
Orthodontic forces are strongly associated with pain, the primary complaint among patients wearing orthodontic braces. Compared to other side effects of orthodontic treatment, orthodontic pain is often overlooked, with limited clinical management. Orthodontic forces lead to inflammatory responses in the periodontium, which triggers bone remodeling and eventually induces tooth movement. Mechanical forces and subsequent inflammation in the periodontium activate and sensitize periodontal nociceptors and produce orthodontic pain. Nociceptive afferents expressing transient receptor potential vanilloid subtype 1 (TRPV1) play central roles in transducing nociceptive signals, leading to transcriptional changes in the trigeminal ganglia. Nociceptive molecules, such as TRPV1, transient receptor potential ankyrin subtype 1, acid-sensing ion channel 3, and the P2X3 receptor, are believed to mediate orthodontic pain. Neuropeptides such as calcitonin gene-related peptides and substance P can also regulate orthodontic pain. While periodontal nociceptors transmit nociceptive signals to the brain, they are also known to modulate alveolar bone remodeling in periodontitis. Therefore, periodontal nociceptors and nociceptive molecules may contribute to the modulation of orthodontic tooth movement, which currently remains undetermined. Future studies are needed to better understand the fundamental mechanisms underlying neuroskeletal interactions in orthodontics to improve orthodontic treatment by developing novel methods to reduce pain and accelerate orthodontic tooth movement-thereby achieving "big gains with no pain" in clinical orthodontics.

Abstract
Pain relief is an integral component of any orthodontic procedure given its high association with patient compliance and treatment adherence. A transdermal drug delivery system (TDDS) is a non-invasive method of drug delivery through the skin surface that can spread the medication throughout the dermis at a predetermined rate to produce a local or systemic effect. It might be used in place of hypodermic injections and the oral medication route. A transdermal analgesic, often known as a pain reliever patch, is an adhesive patch that contains medication to treat mild-to-severe pain. Many opioids and non-steroidal anti-inflammatory drugs are currently available as patches. TDDS offers many benefits over the conventional medication delivery method. The non-invasive transdermal route or therapy has features such as excellent bioavailability, stable medication plasma concentration, and no first-pass metabolism effect. This review aims to explore the available evidence on the use of transdermal patches for pain relief in orthodontic procedures and possibly suggest recommendations based on the findings.

Abstract
BACKGROUND Orthodontic treatment is a time-consuming and highly technique-sensitive clinical procedure. A patient's comprehension and compliance with oral hygiene instructions and appliance maintenance are critical to the success of orthodontic treatment. This study was performed to assess the knowledge, attitude and practice of patients seen at government orthodontic clinics in the Federal Territories of Kuala Lumpur and Putrajaya towards orthodontic treatment. METHODS A validated, bilingual, self-administered questionnaire comprising fifteen questions across the domains of Knowledge, Attitude and Practice was used and responses were assessed with 3 responses; one correct, one incorrect and one reflecting uncertainty. 507 patients from five orthodontic centres participated in this study. Data was analysed using SPSS. Continuous data was summarised as mean and standard deviation or median and inter-quartile range, as appropriate. Categorical data was summarised as frequency and percentage, then univariable analysis was carried out with Pearson's chi-square test or Fisher's exact test, as appropriate. RESULTS The mean age of respondents was 22.5 years (SD ± 2.8). A majority of respondents were female (64.1%) and from the lowest income bracket or B40 group (71%). Overall, for the knowledge domain, a majority of the respondents got all questions correct. 69.4% of patients were aware that incomplete treatment could lead to worsening of their malocclusion. 80.9% of respondents were aware of the need for a retainer upon completion of their orthodontic treatment. For the attitude section, 64.7% felt that they had to wait a very long time to see the orthodontist. In the Practice domain, the majority only got two of the five questions correct. Only 39.8% of respondents made an effort to alter dietary habits all of the time. In general, females and those with tertiary education fared better for all three domains. CONCLUSIONS The orthodontic patients in the Federal Territories of Kuala Lumpur and Putrajaya possess good knowledge about their treatment however their attitude and orthodontic related practices need to be improved.

Pain and discomfort perception during miniscrew-anchored maxillary protraction: secondary data analysis of a randomized clinical trial. Angle Orthod 2023; 93:490739. [PMID: 36795039 PMCID: PMC10117207 DOI: 10.2319/092022-655.1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2022] [Accepted: 12/01/2022] [Indexed: 02/17/2023] Open
Abstract
OBJECTIVES To compare the perception of pain and discomfort of patients and guardians during treatment between miniscrew-anchored maxillary protraction (MAMP) therapy using Hybrid (HH) and Conventional Hyrax (CH) expanders. MATERIALS AND METHODS Group HH was composed of 18 subjects (8 female, 10 male; initial age: 10.80 years) with Class III malocclusion treated with a hybrid expander in the maxilla and two miniscrews in the anterior region of the mandible. Class III elastics were used from maxillary first molar to mandibular miniscrews. Group CH was composed of 14 subjects (6 female, 8 male; initial age: 11.44 years) treated with a similar protocol except for conventional Hyrax expander. Pain and discomfort of patients and guardians were assessed using a visual analog scale immediately after placement (T1), after 24 hours (T2), and 1 month after appliance installation (T3). Mean differences (MD) were obtained. Intergroup and intragroup timepoint comparisons were performed using independent t-tests, analysis of variance for repeated measures and Friedman test (P < 5%). RESULTS Both groups demonstrated similar levels of pain and discomfort with a significant decrease after 1 month of appliance placement (MD: 4.21; P = .608). Compared to patient perceptions, guardians reported a higher level of pain and discomfort at all timepoints (MD, T1: 13.91, P < .001; T2: 23.15, P < .001; T3: 9.35, P = .008). CONCLUSIONS MAMP therapy with HH and CH produced similar levels of pain and discomfort after appliance installation until 1 month after treatment. Pain and discomfort may not influence the choice between HH and CH expanders.

Abstract
OBJECTIVE We aimed to assess whether personality traits affect the relationship between malocclusion and the psychosocial impact of dental aesthetics and whether they act as its mediators or moderators. SETTINGS AND SAMPLE POPULATION The cross-sectional study included 252 participants with permanent dentition (62% female) aged 12-39 years. MATERIALS AND METHODS The Big Five Inventory, the Psychosocial Impact of Dental Aesthetics Questionnaire and the Index of Complexity, Outcome and Need were used. Moderation and mediation were tested by hierarchical stepwise multiple linear regression. RESULTS Malocclusion was the most significant predictor of dental self-confidence (DSC), aesthetic concern (AC), social impact (SI) and psychological impact (PI), accounting for 12%-28% of respective variability (P < .05). Adult age, male sex and higher neuroticism and agreeableness were additional predictors of higher DSC (P < .05). Adolescent age was a predictor of higher AC, SI and PI, and female sex of higher AC and PI (P < .05). Mediation by personality traits was not proven, however, openness, agreeableness and neuroticism were moderators. A tendency of decrease in AC was associated with an increase in malocclusion complexity in adolescents lower in openness and decrease in SI in adolescents with lower agreeableness. There was also a tendency of higher increase of AC associated with an increase of malocclusion degree in adults higher in neuroticism. CONCLUSION In adolescents, openness and agreeableness moderate the relationship between malocclusion and AC and SI, respectively. Neuroticism is a moderator of the association between malocclusion and AC in adults.

Abstract
Patients’ decisions regarding orthodontic treatment are influenced by a variety of factors, such as their subjective opinions of how their oral cavity looks, age, gender, educational level, and income. The present study aimed to measure the orthodontic treatments needs for the Saudi Arabian population, and also to report potential barriers towards it. It is an observational study with cross sectional design. Data was collected from nationals and residents living in Saudi Arabia and who are at least 18 years old. A total of 1184 adult patients (880 females and 304 males) were included in this study. The population for the study was reached and chosen using a non-probability snowball sampling method. A validated and reliable questionnaire was distributed to the participants electronically through google form. Inferential statistics was applied using Pearson Chi Square test. p value < 0.05 was considered significant. The majority of the sample (73.2%) exhibited a favorable attitude toward orthodontic treatment. Most participants including male and female gender wanted orthodontic treatment primarily to have their protruding teeth fixed. The proportion of persons who cited chewing difficulty as the reason they needed orthodontic treatment was strongly influenced by the monthly income variable (p = 0.005). Cost and time of orthodontic therapy were the biggest obstacles to undergoing treatment, accounting for 34.5% and 19.5%, respectively. There was highly significant difference between the underlying medical conditions and the age and monthly income variables (p = 0.000). Based on the findings of the present study, it can be concluded that protruding teeth are the most important treatment needs perceived by the Saudi population, followed by spacing in between teeth, crowding of teeth, and unaesthetic smile. Cost of the orthodontic treatment was identified as the most significant barrier to the treatment needs, followed by long duration of orthodontic treatment, and pain.

Abstract
This within subject clinical experiment assessed oral health impacts before and after Invisalign orthodontic treatment and their relationships with personality characteristics. 50 patients (26 females and 24 males; mean age = 27.62 ± 8.25 years, SE = 1.17, 95% CI = 24.71–29.89 years) were assessed before and after treatment with Invisalign orthodontic treatment. Treatment clinical success was evaluated according defined clinical guidelines. Oral health impacts before and after Invisalign orthodontic treatment were measured via the Oral Health Impact Profile (OHIP). Personality features were measured via the NEO Five-Factor Inventory (NEO-FFI). Probability of α = .05 was utilized to identify significant findings. Females scored less OHIP scores after treatment (had less negative impacts) in comparison to baseline OHIP scores (t = 3.782, df = 25, P = .001, 95% CI of mean difference = 2.750–9.327). Among males, openness scores (R2 = .911, B = 5.235, 95% CI for B = 0.062–10.407, t = 2.601, P = .048) were able to predict OHIP scores before treatment; meanwhile, extraversion (R2 = .959, B = − 8.224, 95% CI for B = − 14.605–1.843, t = − 3.313, P = .021), openness (R2 = .959, B = 21.795, 95% CI for B = 10.737–32.853, t = 5.067, P = .004), and conscientiousness (R2 = .959, B = 10.293, 95% CI for B = 4.796–15.790, t = 4.813, P = .005) scores were useful to predict OHIP scores after treatment (R2 = .959, P < .05). NEO-FFI scores were not useful to predict OHIP scores before or after treatment among females (P > .05). These findings demonstrate that oral health impacts of Invisalign orthodontic treatment and personality profiles contribution to oral health impacts were different between genders.

Abstract
OBJECTIVE This prospective study aimed at assessing the effects of anxiety and a follow-up text message on pain perception after the installation of fixed orthodontic appliances and its impact on the patients' routine. METHODS The sample of this study consisted of 103 orthodontic patients, 40 males and 63 females (mean age 20.5 years), distributed in two groups: G1 (n=51), including control patients that did not receive any post-procedure communication; and G2 (n=52), including patients that received a structured text message. In baseline phase, the patients completed a questionnaire to assess their level of anxiety prior to treatment. Pain was assessed by using 100-mm visual analog scale (VAS) in baseline and ten times prospectively in predetermined time points. VAS was also applied to assess the patient's routine alterations caused by the pain. All data were analyzed using ANOVA, Tukey, Mann-Whitney, t-test, chi-square and Spearman's correlation tests. All statistical tests were performed with significance level of 5%. RESULTS Low-level and high-level anxiety was observed in 42.7% and 7.8% of the patients, respectively. Statistically significant correlation was observed between anxiety and pain (p< 0.05). Maximum mean pain intensity was detected in the second treatment day (G1=36.9mm and G2=26.2mm) and was significantly higher in G1. Nearly 53% of the patients in G1 reported alterations in the routine (18.8mm), while in G2 the percentage rate reached 28.8% (9.9mm) (p=0.013). CONCLUSIONS Anxious patients report more pain after the installation of orthodontic appliances. Text messages were effective to reduce pain levels and to decrease the negative effects on patients' daily routine.

Abstract
OBJECTIVES To investigate content of orthodontic-related videos on YouTube to improve the understanding of orthodontic patients' perceptions and treatment experiences. MATERIALS AND METHODS A systematic search was conducted on YouTube on March 20, 2018, and updated on August 4, 2019, to identify all relevant videos using search terms "orthodontic," "orthodontics," "braces," and "orthodontic braces." The data set was captured from YouTube Data API (Application Programming Interface) and stored in an Excel database using a query function written in Python. All videos captured were viewed and categorized by three independent dental investigators using thematic analysis. The top 100 videos (by view count) related to patients' treatment experience were further analyzed using discourse analysis. RESULTS A total of 600 orthodontic videos were screened, and 546 were included in the study. Six main themes were identified: (1) individual review of orthodontic treatment (45.8%, n = 250), (2) entertainment (19.8%, n = 108), (3) education (18.3%, n = 100), (4) advertisements (6.6%, n = 36), (5) time lapse of orthodontic treatment (5.3%, n = 29), and (6) do-it-yourself orthodontics (4.2%, n = 23). Of the top 100 videos related to patient's individual review of treatment, patients' main focuses were on pain (24%), problems with chewing and swallowing (12%), and adhesive removal (10%). CONCLUSIONS Orthodontic-related YouTube videos are diverse in nature. The most common video category was video providing an individual review of orthodontic treatment experience. Other popular video categories included entertainment, education, and advertisements. A range of do-it-yourself YouTube videos were also identified. YouTube may provide an opportunity for orthodontic professionals to disseminate health information.

Abstract
Background The biological responses involved during retention phase have been studied for many years but little is known about the effect of saliva proteome during retention phase of post-orthodontic treatment. This study aims to identify the protein profiles during retention phase in relation to biological processes involved by Liquid Chromatography Mass Spectrometry (LC-MS) approach. Material and Methods A total of 5 ml of unstimulated saliva was collected from each subject (10 non-orthodontic patients and 15 post-orthodontic patients with 6-months retention phase). Samples were then subjected to LC-MS analysis. The expressed proteins were identified and compared between groups. Incisor irregularity for both maxilla and mandible were determined with Little’s Irregularity Index at 6-months retention phase. Results 146 proteins and 135 proteins were expressed in control and 6-months retention phase group respectively. 15 proteins were identified to be co-expressed between groups. Immune system process was only detected in 6-months retention phase group. Detected protein in immune system process was identified as Tyrosine-protein kinase Tec. Statistical significant of incisor irregularity was only found in mandible at 6-months retention phase. Conclusions Our study suggests that immune system process protein which is Tyrosine-protein kinase Tec could be used as biomarker for prediction of stability during retention phase of post-orthodontic treatment. Key words:Orthodontics, proteomics, retention, LC-MS, saliva.

Abstract
Aim The study was done to evaluate the pain perception, attitude, and personality trait of the patient toward orthodontic treatment. Materials and Methods In this cross-sectional questionnaire survey, 100 patients were divided into Group 1, 150 (75 males and 75 females) as untreated group and Group 2, 150 as treated group (75 males and 75 females). Evaluation of the patients was done based on pain perception, attitude, and personality trait. Set of questionnaire was used to assess attitude and pain perception on visual analog scale. The data were tabulated, and statistical evaluation was done using statistical software IBM SPSS Statistics for Windows, (Version 21.0. Armonk, NY: IBM Corp.) using t-test and Tukey's test. Results The mean pain perception for Group 1 was 4.8 ± 1.30 and 4.17 ± 1.58 in Group 2; the difference was not statistically significant (P = 0.26). The mean value for attitude in Group 1 was 3.57 ± 1.21, and in Group 2, it was 3.39 ± 1.60 (P = 0.09). There was statistically significant difference in pain perception between low (L) level to high level (H) neuroticism (P = 0.009). There was significant difference (P = 0.021) in pain for conscientiousness from very low to very high levels which is directly proportional. Conclusion The present study indicated that attitude, personality traits, and pain perception have a definite role in patient cooperation and success of orthodontic treatment.

Abstract
Objective To investigate whether pain catastrophizing and personality traits bias recalled ratings of acute pain in an experimental tonic pain model. Subjects and Setting Fifty-six undergraduates (14 males) recruited from the University of Peradeniya (mean age 21.7 ± 0.8 SD years). Design and Methods Participants completed the Pain Catastrophizing Scale and the Eysenck Personality Questionnaire. They were subjected to two cold pressor tests (dominant and non-dominant hands) and pain threshold, maximum pain intensity, and pain tolerance were recorded. One-week later, the maximum pain intensities of both hands were recalled and percentage distortions in recalling were calculated. Based on a 180 s cutoff, two participants were considered pain-insensitive during the test and were excluded from the analysis. Results The maximum pain intensity was recalled with a moderate accuracy (Intraclass Correlation Coefficients = 0.68 for dominant and 0.59 for non-dominant hands). Hierarchical multiple regression analyses revealed that maximum pain intensity ( P < 0.001) and pain catastrophizing ( P < 0.001) contributed significantly to recalled pain intensity, and only pain catastrophizing contributed significantly ( P < 0.001) to percentage distortion in recalling with positive β-coefficients. Participants who consistently overrated pain for both hands in recalling scored significantly higher on catastrophizing ( P < 0.001). Conclusion This study demonstrated that memory for painful events in healthy subjects was reasonably accurate over a period of 1 week. Pain catastrophizing biased pain recall, whereas among personality traits only neuroticism exhibited a weak positive association with the recalled ratings.

Abstract
OBJECTIVE This questionnaire study aimed to estimate the overall frequencies of positive perception towards orthodontic treatment among adults categorized according to age, sex, and area of living, and to identify barriers or negative perceptions preventing them from receiving orthodontic treatment. METHODS The participants included 598 adults aged over 20 years (230 men and 368 women) who visited the Dental Hospital of Seoul St. Mary's Hospital. The participants' opinions regarding their consideration of receiving orthodontic treatment were recorded using a specially designed questionnaire. RESULTS The overall rate of positive perception towards orthodontic treatment was 48.5%. Compared to adults in their 20s (63.2%), those in their 40s and 50s had a lower percentage of interest in orthodontic treatment (46.2% and 45.1%, respectively; p < 0.05). Overall, women (52.2%) had a higher rate of interest than did men (42.6%; p < 0.05). The area of living had no effect on the percentage of interest. The order of priority of chief complaints differed according to age: protrusion for those in the 20s and 30s, and spacing for those in the 40s to 60s. Overall, the main reason for not seeking treatment was the treatment fee. Respondents aged over 40 considered themselves "too old" for orthodontic treatment. CONCLUSIONS The middle-aged had a relatively high percentage of interest (above 45%) in orthodontic treatment. However, demographic characteristics were not significantly associated with the positive interest. These results highlight the need for educating the middle-aged about the limitations and possibilities of orthodontic treatment to increase its acceptance.

Abstract
Most of the orthodontic patients experience pain during treatment and this significantly influences their attitudes and the approach towards treatment. A number of factors that influence pain response include age, gender, personal pain threshold, mood and stress level of the person, cultural differences and types of orthodontic treatment. Pain is a often overlooked subject by orthodontists, it is nevertheless important to understand the source and mechanism of the pain that occurs during treatment, as well as the methods for managing and controlling this pain. This review attempts to overview the mechanism, duration and current management strategies of orthodontic treatment.

Abstract
Objective: To investigate the intensity of pain adolescent orthodontic patients experience following the insertion of separators. Materials and Methods: Elastomeric separators were placed mesially and distally to the first molars in 62 adolescents (20 male, 42 female, age 12–15 years), and the participants were given self-administrated questionnaires to document perceived pain, pain upon chewing, and the severity of pain's affecting daily life, using a visual analog scale for seven days. Results: The mean perceived pain scores out of 100 on the first 3 days were 54.6 ± 32.7, 51.7 ± 29.9, and 32.3 ± 28.4, respectively; chewing pain scores were: 61.9 ± 35.3, 52.6 ± 30.4, and 39.5 ± 32.1, respectively; the pain's affecting daily life scores were 24.9 ± 35.5, 21.1 ± 30.9, and 11.9 ± 23.7, respectively. A Kruskal–Wallis test showed a statistically significant difference in the reported pain between the three studied parameters. A Mann–Whitney U-test showed an insignificant difference between male and female adolescents. Conclusion: Pain perception varies among adolescent patients, but it decreases significantly after the first 2 days, with no gender differences.

Abstract
AIM To investigate whether pretreatment assessment of experimental pain can predict the level of pain after archwire placement. METHODS One hundred and twenty-one general university students seeking orthodontic treatment were enrolled in this study. A cold pressor test was performed to estimate the pain tolerance of subjects before treatment. Self-reported pain intensity was calculated using a 10 cm visual analog scale during the 7 days after treatment. The relationship between pain tolerance and orthodontic pain was analyzed using Spearman's correlation analysis. RESULTS The maximum mean level of pain intensity occurred at 24 hours after bonding (53.31±16.13) and fell to normal levels at day 7. Spearman's correlation analysis found a moderate positive association between preoperative pain tolerance and self-reported pain after archwire placement (P<0.01). There was no significant difference in pain intensity between male and female patients at any time point (P>0.05). CONCLUSION A simple and noninvasive preoperative sensory test (the cold pressor test) was useful in predicting the risk of developing unbearable pain in patients after archwire placement. Self-reported pain after archwire placement decreased as individual pain tolerance increased.

Abstract
OBJECTIVE To compare personality traits, attitude toward orthodontic treatment, and pain perception and experience before and after orthodontic treatment. MATERIALS AND METHODS One hundred subjects (50 male and 50 female) were included in this study. The mean (SD) age was 17.5 (2.05) years at T1 and 19.15 (2.32) years at T2. The instruments for data collection were questionnaires that included assessment of patients' personality traits, attitudes toward orthodontic treatment, and pain perception/experience. Subjects completed the questionnaires at two different times: before orthodontic treatment (T1) and after fixed orthodontic treatment (T2). Subjects were treated by fixed orthodontic appliances for an average (SD) period of 18.64 (0.35) months. Paired sample t-test and chi-square test were used to detect any differences. RESULTS Significant changes in personality traits were detected after orthodontic treatment irrespective of gender. Neuroticism, openness, agreeableness, and conscientiousness scores were improved (P < .001). A positive attitude toward orthodontic treatment was reported at T1 (4.31 [±1.26]) and improved at T2 (3.98 [±1.16]) irrespective of gender (P < .05). The average (SD) expected pain score (T1) was 4.73 (1.88) and the average (SD) experienced pain score (T2) was 4.63 (1.58). Significant difference in the expected and experienced pain scores was not detected (P = .11). CONCLUSIONS Personality traits and attitude toward orthodontic treatment improved after orthodontic treatment. Reported actual pain experience during orthodontic treatment was similar to that expected before treatment.

Abstract
The purpose of the study was to evaluate whether, in asymptomatic subjects, there are differences in: (i) head posture while sitting and standing still and (ii) trigeminal nerve mechanosensitivity, between those who have a history of using orthodontics and those who do not. The sample consisted of 72 subjects (21 +/- 2.14 years): one group who had used orthodontics in the past (n = 37), and another group who had not had previous orthodontic treatment (n = 35). The authors measured the CranioVertebral Angle (CVA) while the subject was sitting and standing still by means of lateral photographs, and the pressure pain threshold (PPT) of the trigeminal nerve. The orthodontics group showed a more upright position of the head when sitting compared to the non-orthodontics group, with the difference being statistically significant (ANOVA test; p < 0.001; F1,70 = 16.705; R2 = 0.19), but not for the standing position (p = 0.538). The values of the PPT in the trigeminal nerve (supraorbital-V1, infraorbital-V2 and mandibular-V3) were lower on both sides (dominant and nondominant) in the non-orthodontics group. The between-group comparison (ANOVA test) showed statistically significant differences for the trigeminal nerve PPT in its different branches (V1 p = 0.001; F1,70 = 13.012; R2 = 0.15) (V2 p = 0.004; F1,70 = 9.103; R2 = 0.11) (V3 p = 0.005; F1,70 = 8.228; R2 = 0.10). Based on these observations, it was concluded that subjects with a history of orthodontic use show a better sitting craniocervical posture and mechano-sensitivity of the trigeminal nerve branches compared to the group that had not used orthodontics in the past.

Abstract
The importance of the upper airway (nose, pharynx, and larynx) in health and in the pathogenesis of sleep apnea, asthma, and other airway diseases, discussed elsewhere in the Comprehensive Physiology series, prompts this review of the biomechanical properties and functional aspects of the upper airway. There is a literature based on anatomic or structural descriptions in static circumstances, albeit studied in limited numbers of individuals in both health and disease. As for dynamic features, the literature is limited to studies of pressure and flow through all or parts of the upper airway and to the effects of muscle activation on such features; however, the links between structure and function through airway size, shape, and compliance remain a topic that is completely open for investigation, particularly through analyses using concepts of fluid and structural mechanics. Throughout are included both historically seminal references, as well as those serving as signposts or updated reviews. This article should be considered a resource for concepts needed for the application of biomechanical models of upper airway physiology, applicable to understanding the pathophysiology of disease and anticipated results of treatment interventions.

Abstract
OBJECTIVE To investigate the relationship between primary dysmenorrhea (PD) and orthodontic pain in female patients, and to test the hypothesis that the intensity and duration of orthodontic pain could be roughly predicted by severity of PD. MATERIALS AND METHODS One hundred twenty college females were enrolled and put into one of three groups-mild (Mi), moderate (Mo), or severe (S)-according to level of menstrual pain. Intensity of the orthodontic pain was measured by visual analog scale (VAS) on days 1, 2, 4, 7, 14, and 28 after archwire placement. RESULTS As the intensity of orthodontic pain declined with time, the three groups demonstrated different changes during the initial week. Mi had the lowest VAS scores, whereas S possessed the highest scores. In contrast, Mo stayed in between. Significantly positive correlations were found between the severity of PD and the intensity of orthodontic pain at each time point within the first 2 weeks. In addition, though the majority of subjects reported disappearance of pain by the end of the second week in both Mi and Mo, a large proportion of females still perceived pain in S. CONCLUSION Females with higher levels of menstrual pain tended to perceive orthodontic pain with higher intensity and more prolonged duration. Thus, PD could potentially serve as a reference to predict orthodontic pain in clinical settings.

Abstract
Objective. To identify participants' satisfaction with appearance and the desired treatment to improve aesthetics. Materials and Methods. 220 participants (127 males and 93 females, mean age = 21.4 ± 1.5 years) were recruited into the study. A structured questionnaire was used to assess patients' satisfaction with appearance and what treatment they desire to improve aesthetics. Participants scored the level of satisfaction with appearance using visual analogue scale. Results. The VAS mean score of satisfaction with general appearance was 6.8 ± 2.3. Half participants were dissatisfied with tooth appearance and 65.9% were dissatisfied with tooth colour. Higher VAS scores were associated with higher desire for all treatments that improve tooth appearance (P < .05). Dissatisfaction with tooth appearance increased with increased dissatisfaction with teeth colour, feeling of poor tooth alignment, presence of fractured anterior teeth, and increased desire for orthodontic, crowns, and dentures treatments (P < .05). Dissatisfaction with tooth colour was associated with increased desire for tooth whitening and tooth coloured fillings (P < .05). Conclusions. Participants had high levels of dissatisfaction with tooth appearance and tooth colour. Dissatisfaction with tooth colour contributed to the increased dissatisfaction with tooth appearance. Dissatisfaction with tooth appearance, colour, alignment, and condition was significantly related to high desire for aesthetic treatments.

Abstract
OBJECTIVE To evaluate the impact of psychological traits on patients' choice of orthodontic appliances and their adjustability to orthodontic treatment. MATERIALS AND METHODS The sample consisted of 68 adult patients divided into three groups (28 buccal, 19 lingual, and 21 clear aligners). Prior to treatment participants filled out the Brief Symptom Inventory to assess symptoms of mental distress and the Narcissistic Vulnerability Scale to assess narcissistic personality traits. During the first week after appliance delivery and on day 14, patients completed a Health-Related Quality of Life questionnaire to assess their perception of pain and four areas of dysfunction. The correlation between personality traits and patients' reaction to treatment was evaluated. RESULTS Somatization was the only trait that affected the choice of lingual and clear aligner appliance. Reduced self-esteem regulation was associated with increased pain in all patients, while exploitation was associated with pain in lingual patients. Narcissistic vulnerability slightly influenced patients' adaptability to orthodontic appliances. Although adjustability to lingual appliances was the most difficult, only two parameters were affected by personality features. In the buccal group, adjustability was affected by numerous parameters. Adaptation to the clear aligner appliance was relatively uneventful and least affected by psychological features. CONCLUSION Anxious individuals tend to prefer lingual and clear aligner appliances. The selection of lingual and clear aligner appliances governs the patient's response and recovery process, leaving little room for the effect of psychological features. On the other hand, the buccal appliance allows for greater impact of personality traits on adjustability.
