For many years, malocclusions have remained one of the most common dental pathologies in the world. Malocclusions are found in every second child and teenager in the world, and their prevalence does not change depending on the stage of the bite. Having polyetiological causes, malocclusions affect most body systems, which are closely related to the functions of respiration, chewing, swallowing, and speech. Our goal was to obtain up-to-date data on the prevalence of malocclusion in children during the period of mixed and early permanent occlusion. In this study, we examined 674 children aged from 6 to 13 years (with the mean age of 9.2). The examined patients' occlusion was assessed in three planes: sagittal, vertical, and transverse. In the sagittal plane, the occlusion was assessed according to Angle’s classification, children were divided into three groups according to this criterion: class I, class II, class III. The overbite was estimated in the vertical plane. Children were divided into three groups: normal group, overbite, open bite. The overlap in the lateral areas was estimated in the transverse plane. Children were divided into three groups according to this criterion: normal group, bilateral crossbite, unilateral crossbite. In 94.51% of all children aged from 6 to 13 years, living in the city of Kyiv and Kyiv region, there was a malocclusion in one of the three planes, regardless of the gender. Only 5.49% of children did not have a malocclusion. Among the total number of children examined, class I was observed in 324 children, class II in 296 children, class III in 54 children. Among all examined children aged from 6 to 13 years, overbite was diagnosed in 57.27% (386 children). The open bite was determined least often, with the incidence rate of 9.64% (65 children) among the examined 674 children. Unilateral crossbite was observed in 58 children (8.61%) among 674 subjects. In most cases, namely, in 43 children (74.14%) out of 58 children, unilateral crossbite was accompanied by the midline displacement. Bilateral crossbite was detected in 163 children (24.18%) among the total number of respondents. Bite anomalies in sagittal and vertical planes were observed in 444 children (65.88%), 91 children (13.5%) in the sagittal and transverse planes, 43 children (6.38%) in the vertical and transverse planes, and 59 children (8.75%) in all planes. Developing a strategy for early prevention and treatment of malocclusion in children, as well as eliminating bad habits are important factors in combating the growing number of patients with orthodontic pathologies. Our data indicate a high prevalence of malocclusion among children and teenagers and the need to review the prevention management and early treatment of children of this age group.

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.

Abstract Objective: Considering that the available studies on prevalence of malocclusions are local or national-based, this study aimed to pool data to determine the distribution of malocclusion traits worldwide in mixed and permanent dentitions. Methods: An electronic search was conducted using PubMed, Embase and Google Scholar search engines, to retrieve data on malocclusion prevalence for both mixed and permanent dentitions, up to December 2016. Results: Out of 2,977 retrieved studies, 53 were included. In permanent dentition, the global distributions of Class I, Class II, and Class III malocclusion were 74.7% [31 - 97%], 19.56% [2 - 63%] and 5.93% [1 - 20%], respectively. In mixed dentition, the distributions of these malocclusions were 73% [40 - 96%], 23% [2 - 58%] and 4% [0.7 - 13%]. Regarding vertical malocclusions, the observed deep overbite and open bite were 21.98% and 4.93%, respectively. Posterior crossbite affected 9.39% of the sample. Africans showed the highest prevalence of Class I and open bite in permanent dentition (89% and 8%, respectively), and in mixed dentition (93% and 10%, respectively), while Caucasians showed the highest prevalence of Class II in permanent dentition (23%) and mixed dentition (26%). Class III malocclusion in mixed dentition was highly prevalent among Mongoloids. Conclusion: Worldwide, in mixed and permanent dentitions, Angle Class I malocclusion is more prevalent than Class II, specifically among Africans; the least prevalent was Class III, although higher among Mongoloids in mixed dentition. In vertical dimension, open bite was highest among Mongoloids in mixed dentition. Posterior crossbite was more prevalent in permanent dentition in Europe.

The objective of this work was to determine the prevalence of individual traits of malocclusion in a sample of three Brazilian regions orthodontic patients and to detect interregional population differences in the prevalence of certain occlusal characteristics.  The present study was based on the examination of dental casts, intraoral photographs and panoramic radiographs of 947 orthodontic patients from 3 cities: 363 from Fortaleza (CE), 270 from Maringá (PR) and 314 from Bauru (SP), respectively, representing the Northeast, South and Southeast Brazilian regions. The relationship of the first maxillary and mandibular molars according to Angle’s classification, overjet, overbite, crowding, posterior crossbite and maxillary median diastema were examined. The chi-square and ANOVA tests were used to determine potential differences in the distribution of malocclusion when stratified Brazilian regions. Class I malocclusion was found in 499 (52.69%), Class II in 395 (41.71%) and Class III malocclusion in 53 (5,59%) subjects of all examined. Deep overbite (3.59%), midline diastemas (5.17%) and posterior crossbite (4.75%) were observed more frequently in Bauru; however, in Maringá, normal overbite (13.3%) and open bite (4.75%) were more prevalent. The results of this study showed that Class I malocclusion was the most prevalent, followed by Class II and Class III malocclusions. These occlusal relationships evaluated in the three Brazilian regions follow the same pattern of frequency as the result presented by the general population of the sample.

Objective: Malocclusion is every difference in the arrangement of teeth beyond the standard of regular occlusion illustrated by anomalies within the dental arches. The purpose of this study was to measure prevalence of malocclusion between primary school children in Sana’a city Yemen. Methods: A cross sectional study was conducted on 1079 school children (546 girls and 533 boys), their age ranged from 7 to 12 years old from public and private schools selected randomly in Sana'a City, Yemen. The prevalence of malocclusion was investigated according to age, gender and school type based on Angle's classification. Results: The study showed that the overall prevalence of malocclusion among school children was 81.1%, in which Class I normal molar association was found only in 18.9% of school children, while Class I malocclusion included the highest percentage of the sample 70.4%, followed by Class II relation 9.5%, and Class III involved only 1.1%. The most prevalent malocclusion trait was spacing 35.7%, whereas the crowding was present in 30.0% of the sample. The deep bite was present in 10.1% followed by anterior crossbite 8.8%, midline diastema 8.6%, anterior open bite 4.5%, posterior crossbite 4.0%, and the least noted malocclusion trait was posterior open bite 0.4%. Conclusion: In conclusion, there was a high rate of malocclusion in school children and significantly increased with age, class I malocclusion was the most common followed by Class II malocclusion, while Class III was the rear. The most prevalent occlusal problem was spacing, followed by crowding.  Thus, 7-12 year-olds can benefit from interceptive and preventive oral health procedures which may either entirely prevent or reduce the development of serious types of malocclusions afterward in their lives.

Aim. To evaluate the orthodontic treatment effects, performed immediately after adenoidectomy, on lips relation, overjet and class (Angle). Methods. Three groups of patients, aged 6?17 years, were observed: group K - patients with oral respiration caused by adenoidal enlargement; group 1 - patients with adenoidectomy performed five and more years previously; group 2 - patients with one year of orthodontic treatment performed immediately after adenoidectomy. Lips and overjet status and class (Angle) was measured in the examined patients. Results. In all of the three examined groups, there was a statistically highly significant increase (p<0.01) of competent lips. In the patients of group K, the overjet values ranged from 1 mm up to 12 mm where 90% of them had overjet > 4 mm and 6% < 1 mm. The front open bite, low overbite and reversed overjet was found in the patients with low overjet in this group, as well. Overjet values in the patients of group 1 ranged from -2 mm up to 12 mm where 86% had overjet > 4 mm and 10% < 1 mm. Significantly higher increase (p<0.01) of overjet values (1?4 mm in 94% of patients) was observed in the patients of group 2 in comparison to the values found in the patients from groups 0 and 1. Class II (Angle) was recorded in 81% of the patients in group 0, and 79% in group 1, while class I (Angle) was observed 100% only in the patients of group 2. Conclusion. Orthodontic treatment immediately after adenoidectomy was necessary for achieving the competition lips relation, normal overjet and class I (Angle).

ABSTRACT Introduction To assess the positional variations of maxillary first permanent molar in horizontal and vertical plane with respect to infrazygomatic crest (key ridge) in skeletal class I, II and III cases. Materials and methods A total of 103 lateral cephalograms comprising of 40 skeletal class I (control group), 35 class II and 28 class III cases were selected and analyzed. Six parameters were chosen to compare the vertical and the horizontal variations of first permanent molars. Results The angulation of maxillary first molar with respect to key ridge in class II and III was 2.42° and 6.97° as compared to class I which was 5.35°. The mesiobuccal cusp tip of maxillary first molar from key ridge in class II and III was 2.11 and 5.46 mm respectively as compared to class I (1.62 mm). The mesiobuccal root tip of maxillary first molar from key ridge in class II and III was 2.14 and 2.82 mm as compared to class I (1.27 mm). Conclusion The maxillary first molar was not directly under the infrazygomatic crest and was ahead of the key ridge in all the groups. The maxillary first permanent molar was placed more mesially in class II and III cases as compared to the class I cases but, in class III, it was more upright as compared to class I and II.

Introduction: Malocclusion is the improper relationship of maxillary and mandibular teeth. The prevalence of malocclusion varies in different populations of the world.Objective: To study the prevalence of malocclusion in western part of Nepal and to evaluate the gender variation in occurrence of malocclusion.Materials & Method: A total of 1284 subjects were studied. Out of them 656 were male and 628 were female. Intra-oral examination was carried out to assess occlusal types of Class I, II, III according to Angle’s classification of malocclusion, and various occlusal characteristics like crowding, spacing, cross-bite, open-bite and deep bite were recorded. Gender variation in malocclusion characteristics were tested using chi-square test (p<0.05).Result: The present study showed that Class I occlusion type with malocclusion was more prevalent than Class II and Class III malocclusions. Class I was seen in 71.5% , Class II div 1 in 20.7%, Class II div 2 in 3.9% cases and Class III in 4.1% cases. Among the occlusal characteristics; crowding (61.3%), deep bite (29.5%) and spacing (10.5%) were most prevalent.Conclusion: Class I malocclusion was most prevalent type of malocclusion in western Nepalese subjects. There was no significant gender dimorphism between male and female in prevalence of various malocclusion characteristics.

<p><strong>Objective</strong>: To classify the malocclusions and their occlusal and morphofunctional aspects in order to establish possible correlations. <strong>Material and Methods</strong>: The present observational and analytical study was performed within 432 dental records of patients. The patients were aged between 7 and 12 years old (228 males and 204 females) from an Educational Institute in the state of São Paulo, Brazil. The data regarding the malocclusions and the related associations underwent parametric statistical tests for quantitative and qualitative analysis (ANOVA, Tukey test and Chi-square) considering the significance level at 5%. <strong>Results:</strong> Most of the patients had permanent dentition (58.6%), followed by mixed dentition. Angle’s Class II malocclusion was the most prevalent (67.2%), followed by Class I and III. Overbite and anterior open bite represented, respectively, 47% and 7.2% of the vertical discrepancies. The average overbite was 3.08mm, while the average overjet was 4.67mm. Approximately 43,1% of the sample presented moth breathing. Atypical swallowing reached 78.7% of the patients. Statistically significant correlations were observed associating Angle’s Class III malocclusion with anterior cross bite and bilateral posterior cross bite; as well as between Angle’s Class II with overbite, and Angle’s Class I with overbite and atypical swallowing. A correlation was observed between atypical swallowing; the use of pacifiers; and predominant mouth breathing (p&lt;0.001). <strong>Conclusion:</strong> An important correlation was found between the type of malocclusions and the morphofunctional aspects of occlusion in patients aged from 7 to 12 years old, indicating the need for immediate intervention once the diagnosis is established.</p><p> </p><p><strong>Keywords:</strong> Applications of epidemiology, Malocclusion, Child.</p>
