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.

Objective: The occlusal features change dynamically in the growing children and any disruption in the complex craniofacial growth process may lead to malocclusion, which is a major concern for the pediatric community because of its effects on dental function and beauty, as well as on the child's psyche. The aim of the present study was to study the prevalence of different occlusal traits in the primary dentition of the randomly selected pre-school children from three to five years in the city of Sana’a, Yemen. Methods: The study includes 1106 pre-school children subjected to a dental examination performed in the school premise, using the Foster and Hamilton criteria for occlusal traits. As well as inter- and intra-calibration tests were conducted for assessing the degree of agreeability. Results: Results of the study showed that the Bilateral flush terminal molar relationship was found in 60%, bilateral mesial step in 27.9%, asymmetrical relationship in 8.5% and distal step in 3.5% of tested children. The Bilateral canine class I was detected in 62.8%, asymmetrical relationship (13.6%), class II (12.5%) and class III (11.1%). Normal over-jet (OJ) of 1-3 mm was identified in 39.2%, decreased OJ <1 mm (32.7%) and edge-to-edge (8.8%). Ideal over-bite (OB) of 1-50% was detected in 64.5% and increased OB of > 50% (19.7%). Conclusion: In conclusion theBilateral flush terminal molar, class I canine relationships, normal overjet (OJ) of 1-3mm were the most commonly found sagittal occlusal traits in the current study. Ideal over-bite (OB) of 1-50% were identified in more than half of the 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.

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.

The nutritional status of children adversely affects their physical and mental growth. This study examined the nutritional status and morbidity pattern of government primary school children in north Kolkata of West Bengal, India. A cross-sectional study was conducted among 10 primary schools using interview techniques and anthropometric and clinical examinations. Of the 502 children, 40.2% children showed poor hygiene. The upper class students showed significantly poorer hygiene than that of lower class students. Anemia rate was 22.3% in these children and class II and III students showed significantly more anemia. Dental caries were found among 29.9% children and class II and III students showed significantly higher rate. About 10.4% children were found with enlarged tonsils and class I and III students showed higher prevalence. A major group of children (39.4%) gave the history of worm expulsion and the infestations of worms were observed significantly higher among lower class students. Vitamin B-complex deficit was observed among 20.7% and the deficiency was markedly observed among class II and IV students. Under-weight children were found in one-third of study population. There was no significant difference in nutrition among the participants from the various classes. There was no case of severe under-nutrition or stunting and wasting found in this study population. The findings of various nutritional status and morbidity patterns in this study highlight the needs to undertake various initiatives in relation to health promotion and prevention in primary schools.South East Asia J Public Health | Jan-June 2012 | Vol 2 Issue 1 | 13-17 DOI: http://dx.doi.org/10.3329/seajph.v2i1.15255

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.

Background:  Trachoma is a contagious infection caused by Chlamydia trachomatis. The disease causes roughness of the inner surface of the eyelids which in turn leads to eye pain, collapse of the outer surface and scratching of the cornea, and ultimately blindness. Objectives: This study was designed to determine Trachoma prevalence and associated risk factors among primary school children in Sana’a city, Yemen. Methods: A cross-sectional study was performed on 991 schoolchildren aged 6-12 years that were chosen from sixteen primary public schools and ten private ones, that are located in five districts in Sana’a city and represent nearly 10% of total number of schools in Sana’a. Child's eye examination was done by trained 12 students of Medicine, according to WHO grading system for trachoma. Data on risk factors and health characteristics of a child were collected using a structured questionnaire and statistical analysis was performed using Epi-Inf version 6. Results:  The gender distribution of study contributors was male 41.7 % and female was 58.3%. The results of independent associated odds ratio analysis discovered that risk factors of contracting Trachoma from the upper to the lower are: Absent of latrine in the house of child  (OR=10.6,  p<0.001), orphan of mother  (OR=4.7,  p<0.001), absent of water in the house of child (OR=3.9, p<0.001), flies in the face (OR=1.9, p=0.005) , No education of the mother (OR=1.7,  p=0.01), No education of the father (OR=1.6, p=0.04), No  face washing with  soap per day (OR=3.1, p=0.001), keeping animals in living house (OR=1.6, p=0.03), and house overcrowding (OR=2.5, p=0.002). Conclusion: Area was identifiedidentify where, at the time of the survey among 10-12 children, as defined by WHO trachoma was a public health problem. As for the loss of the child to his parents, especially the loss of the mother, it is a disaster for the child, so the treatment of causes such as war and poverty for this problem should be a priority in Yemen                    Peer Review History: Received: 15 July 2021; Revised: 9 August; Accepted: 6 September; Available online: 15 September 2021 Academic Editor:  Dr. Sally A.
