Aims This study aims to find the prevalence of orthodontic treatment need and malocclusion problems in 8–9-year-old schoolchildren in the south of Thailand. Materials and Methods A number of 202 children (100 boys and 102 girls) samples were randomly selected from all schools in Hat Yai District, Songkhla Province, Thailand. A cross-sectional survey of dental health component (DHC) of the Index of Orthodontic Treatment Need (IOTN) and malocclusion problems was investigated by clinical examination and dental model. Results Levels 4 and 5 of orthodontic treatment need according to DHC of IOTN of the sample were presented in 18.8% and 1.49%, respectively. Children who need orthodontic treatment (Grade 2–4) showed more than one highest DHC problem that indicated the level of treatment need (39.68%). Normal occlusion was found at 6.43%. Malocclusions such as Class I, Class II division 1, Class II division 2, and Class III malocclusion were observed in 78.71%, 7.92%, 3.47%, and 3.47%, respectively. Reversed overjet and overjet >9 mm were detected in 5.64% and 1.58%, respectively. Approximately half of the children (46.67%) had overbite >3.5 mm. Conclusions High percentage of children in mixed dentition period who need orthodontic treatment was found in this study. Some children who presented with the orthodontic treatment need Grade 2–4 had more than one DHC problem which identified the grade of treatment need. Class I malocclusion was most frequently found in this group of children.

Introduction: Autism spectrum disorder (ASD) is a group of neurodevelopmental disorders diagnosed by impairments in social interaction and communication with repetitive and restrictive stereotyped behavioral patterns. The Prevalence of autism has been reported to be increased in recent years. This study aimed to assess the prevalence of different types of malocclusion among ASD patients in Isfahan in 2018. Materials & Methods: In a descriptive and cross-sectional trial, 92 ASD patients were studied in the age range of 7-18 years at the center for autism patients in Isfahan. Clinical oral examinations of patients are taken to assess the involved malocclusions (Cl I, Cl II and Cl III malocclusions) and malocclusion traits (deep bite, open bite and cross bite) by an educated dental student under the supervision of an orthodontist under natural light. The data are reported using frequency and percentage indices. Results: Class I malocclusion had the highest prevalence 54.3% (50) among ASD patients and the prevalence of class II and class III were found to be 19.6% (18) and 7.6% (7) respectively. The frequency of malocclusions traits of deep bite, cross bite and the open bite were 27.2% (25), 18.5% (17) and 7.6% (7) respectively. Among of the total patients, 65.2% (60) showed normal bite and 18/5% (17) showed Normal occlusion. Conclusion: ASD patients showed class I, class II and class III malocclusions from the most to least frequency and the most frequent malocclusion traits were also deep bite, cross bite and open bite respectively.

Objectives: To calculate the agreement between the Dental Aesthetic Index (DAI) and the Index of Complexity, Outcome and Need (ICON) in assessing orthodontic treatment need and to determine correlations between the Peer Assessment Rating (PAR) and DAI and ICON scores according to Angle classification among patients referred for orthodontic evaluation. Study Design: This study included 457 randomly selected patients between 9 to17 years of age. Patients were divided into four groups according to Angle classification [Class I (n=154), Class II division 1(Class II/1) (n=155), Class II division 2(Class II/2) (n=52) and Class III (n=96)]. Relationships between PAR scores and ICON and DAI scores were evaluated with the Spearman correlation test. Unweighted kappa statistics were used to analyse agreement between the ICON and DAI on the need for treatment, according to Angle classification. Results: Class I malocclusions scored significantly lower than other Angle classifications in all indices. Both the ICON and DAI showed significant positive correlations with the PAR in the general study population. For Class II/2 patients, no correlation was found between PAR and DAI scores. There was significant agreement between the ICON and DAI on treatment need among Class I, Class II/1 and Class II/2 patients however, no agreement was found for Class III malocclusions. Conclusions: The ICON, DAI and PAR produce similar results and can be used interchangeably for the general orthodontic patient population. However, based on Angle classification, prominent differences exist in scoring certain occlusal features.

Introduction: The purposes of this study were to seek for overall ratio (OR) and anterior ratio (AR) patients data in normal occlusion and Angle’s malocclusion studies, and to assess if such results support Bolton’s standards as general references. Methods: Pubmed, Medline, CENTRAL and Scholar databases were searched up to February 2018 (CRD42018088438). Gray literature was explored through OpenGray. Non-randomized clinical studies, published in English and assessing Bolton’s OR and AR in normal occlusion and Angle’s malocclusion groups (Class I, Class II, Class II division 1, Class 2 division 2, Class III) patients were included. OR and AR means and standard deviations (SD) were collected. Potential covariates (study design, publication year, country where the study was conducted, number of cases, gender, mesiodistal measurement method, and calibration method) were also extracted. The National Health Heart Lung, and Blood Institute’s Quality Assessment Tool for Observational Cohort and Cross-Sectional Studies was used to assess each included studies quality. Pairwise Random-Effects and Multilevel Bayesian Network Meta-Analyses were used to synthesize available data. Results: Fifty-two observational studies were included (8872 participants; male/females 2674/3272; 16 studies lacked gender information). For normal occlusion, global pooled estimates for OR and AR means were 91.74% (95% CI: 91.37-92.10) and 78.24% (95% CI: 77.85-78.63), respectively. We could identify on Angle’s Class III patients meaningful OR and AR mean deviations from normal occlusion (0.89, 95% credible interval [CrI], 0.66-1.12, and 0.66, 95% CrI, 0.38-0.94, respectively), while on Class I patients we found a meaningful mean deviation from normal occlusion only for OR (0.25, 95% CrI, 0.03-0.47). Concerning gender impact, male patients presented higher OR (0.30, 95% CI 0.00-0.59) and AR (0.41, 95% CI 0.00-0.83) mean values than females in Class I. Conclusions: The results show that global pooled OR and AR mean values for normal occlusion patients are slightly above Bolton’s original values. Class I, for OR mean values, and Class III, for both OR and AR, are proportionally larger than normal occlusion patients. Gender had almost no impact on teeth mesiodistal proportion.

ABSTRACT Background Prevalence of malocclusion varies in different parts of a diverse country like India. Aims To determine the prevalence of malocclusion in population of Jaipur city, Rajasthan, India, as well as subjects views regarding the most important factor for seeking orthodontic treatment by patients who have malocclusion. Materials and methods The sample consisted of 700 subjects (373 males and 327 females) with age group of 15 to 30 years. Subjects were randomly selected and none of them had received orthodontic treatment previously. The subjects who showed bilateral Angle's class I molar relationship with acceptable overjet, overbite and well-aligned arches or minimal crowding were considered to have normal occlusion. The subjects with malocclusion were classified into four groups according to Angle's classification, i.e. class I, class II division 1, class II division 2 and class III malocclusions. Results About 74.57% of population was found to have malocclusion. Among these subjects, 52.57% subjects were diagnosed with class I malocclusion, 12.57% with class II division 1 malocclusion, 8% with class II division 2 and remaining 1.42% had class III malocclusion. No statistically significant differences were found between male and female subjects. Conclusion Among class I malocclusion characteristics, Angle's class I type 1 malocclusion was statistically significantly found to be the most prevalent type of malocclusion. As far as the most important factor for seeking orthodontic treatment was determined, a desire of enhancing facial appearance followed by a desire of attaining straight teeth was considered to be the chief motivational factor among this population.

Background: Hypodontia is one of the most common anomalies in dentistry. Hypodontia has a negative impact on oral health-related quality of life with patients best seen in a multidisciplinary clinic to improve treatment outcomes. Aim: To investigate the prevalence of hypodontia and its association with other dental anomalies, as well as malocclusion, and to investigate the treatment planned for patients attending the clinic and whether the type of missing teeth affected the proposed treatment. Materials and Methods: Analysis of consecutive patients attending the hypodontia clinic at a dental hospital between February and November 2020. A total of 100 patients who met the inclusion criteria were identified. Data collected included the following: age/sex; number and type of missing teeth; pre-treatment occlusion; presence of other dental anomalies; and planned treatment. Results: A total of 100 patients (55% female; age range = 7–41 years; mean age = 18 years) were included. Of the cohort, 47% had a class I skeletal relationship and participants were significantly less likely to have a class III skeletal or incisor relationship; 45% had another dental anomaly with the most common being microdontia. Space opening was the preferred treatment option for those managed by orthodontic treatment with resin-bonded bridges most likely to be used for restoration of spaces, 86%. Conclusion: Lower second premolars were the most commonly missing teeth. Participants were significantly less likely to have a class III incisor or skeletal relationship than class I or II. Space opening was the favoured approach for orthodontic treatment, particularly for maxillary lateral incisors.
