Prevalence of Malocclusion among High School Students in Kathmandu Valley
The malocclusion is a malrelationship between the arches in any of the planes or in which there are anomalies in tooth position beyond the normal limits. The epidemiological data has a key role in planning which varies between different countries, ethnic and age groups. Aims and objective: To find out the prevalence of malocclusion among high school students in three districts of Kathmandu valley. Materials and method: The sample consists of 937 children (537 males and 400 females) with the age groups between 14 and 16 years. The samples were selected voluntarily from seven different schools of Kathamandu valley using multistage sampling technique. This is a quantitative, cross-sectional descriptive study. Results: Normal occlusion is found to be in 27 %. The prevalence of Class I malocclusion is 59% followed by Class II (25%) and Class III (16%). Male to female ratio was found to be 57:43%. Out of two major ethnic groups, 64% of Indo Aryans and 36% of Janajati had malocclusion. Moreover, Class II malocclusion was seen more in Indo Aryans than in Janajati populations. Conclusion: The prevalence of normal occlusion was 27% and malocclusion was found to be 73%. Class I malocclusion is most prevalent followed by Class II malocclusion and the Class III malocclusion showed least prevalence.

Orthodontic Journal of Nepal, 2018
Introduction: Occlusal traits in orthodontic patients have been studied in different parts of Nepal. However, very few data are available on malocclusion in south-eastern region of Nepal.Objective: To assess the pattern of malocclusion occurring in orthodontic patients in south-eastern region of Nepal, and to estimate the age of presentation of Class II malocclusion among the patients.Materials & Method: Data were collected from 150 pre-treatment study models and lateral cephalograms from two orthodontic specialty clinics in Biratnagar. Angle’s classification system was used to determine dental malocclusion and ANB angle was used to determine skeletal malocclusion. Chi square test was used to test the association between dental and skeleton malocclusions.Result: Angle’s Class I malocclusion was found in 95(63.33%), Class II Div 1 in 41(27.33%), Class II Div 2 in 13(8.66%) and Class III in 1(0.66%). Among all subjects; 119 (79.33%) had skeletal Class I, 24(16%) had skeletal Class II ...
Epidemiology of Malocclusion and Assessment of Orthodontic Treatment Need for Nepalese Children
International Scholarly Research Notices, 2014
Objective. To evaluate the prevalence of malocclusion and orthodontic treatment needs among 12- to 15-year-old schoolchildren in eastern Nepal and compare the findings with those of other populations. Methods. Two thousand seventy-four children (1149 males and 925 females) aged between 12 and 15 years were evaluated. Their orthodontic treatment need was assessed using the Index of Orthodontic Treatment Needs (IOTN) (dental health component (DHC)). Angle’s classes of malocclusion were also evaluated. Results. The prevalence of classes I, II, and III was 48.50%, 32.68%, and 4.32%, respectively. The IOTN showed that 21.59% had an extreme treatment need, 24.67% had severe treatment need, 24.07% had moderate treatment need, 14.7% had mild treatment need, and 15.02% had no treatment need. Conclusion. Class I malocclusion is the most common, while class III is the least prevalent in eastern Nepal. The majority of the children need orthodontic treatment.

Introduction: Prevalence of malocclusion and orthodontic treatment need varies according to different region based on ethnic diversity.Objective: To assess the prevalence of malocclusion and orthodontic treatment need amongst patients visiting College of Dental Surgery, Gandaki Medical College, Pokhara, Nepal.Materials & Method: A cross-sectional study based on WHO-Oral Health Survey Basic Methods using Community Periodontal Index (CPI) probe and mouth mirror was conducted. The malocclusion based on Angle’s classification, overjet, overbite, open bite, crowding, spacing and cross bites were recorded. Dental Health Components (DHC) of Index of Orthodontic Treatment Need (IOTN) was recorded. The frequency distribution was calculated and chi square test was used to assess the gender difference.Result: The prevalence of normal occlusion was 5.8%, Angle’s Class I malocclusion was 67.9%, Class II was 19.5% and Class III was 6.8%. Crowding (51.07%) was more common malocclusion trait than s...

Introduction: Malocclusion can be defined as a mal-relation between the dental arches in any planes beyond the normal limits. With the rise in concern about good dental appearance, people compare it with success in different fields of life and are always willing to pursue the orthodontic treatment. Objectives: To determine the prevalence of malocclusion and orthodontic treatment needs according to gender, race and age in mixed dentition of school going children of Dharan, Nepal. Methods: A cross sectional study was conducted among 830 school children from 10 randomly selected schools from January 2017 to December 2017. The type of malocclusion was determined using a structured questionnaire and the orthodontic treatment need was calculated based on Dental Aesthetic Index (DAI). Chi-square test was used to test the associations. Results: The prevalence of Class I, Class II division 1, Class II division 2 and Class III malocclusion was 49.11%, 11.43%, 4.03%, and 12.24%, respectively. ...
The Prevalence Of Malocclusion Among The Local Chandigarh Population – A Hospital Based Study
Objective: The objective of this study was to assess the prevalence of malocclusion specifically Class II div 1, Class II div 2 and Class III in a sample of patients in Chandigarh. Data for the patients of study were retrieved from the patient’s orthodontic records who sought orthodontic treatment at during the period of April 2008 through December 2011. Materials & Method:Atotal of 768 patients were screened. All the subjects had full complement of permanent teeth up to second molars. The patients with the history of previous orthodontic treatment, extractions of permanent teeth other than 3rd molars, mixed dentition, congenital malformations like Cleft lip or/and palate and systemic diseases were excluded from the study. Assigning the subjects to various occlusal traits was based purely on clinical examination, study models, facial photographs, lateral cephalograms and orthopantomograms for assessment. Results: Class II malocclusion was more prevalent than Class III malocclusion. Out of Class II malocclusion, Divison 1 is more common among various types followed by Class II div 2. Females reported more for orthodontic treatment than males. Conclusion: Class II malocclusion is the most common malocclusion seen in the Chandigarh Population with females reporting more for orthodontic treatment than males because of esthetic reasons.

Aim: To determine the prevalence rates of different occlusal characteristics of permanent dentition in 12 to 14 years old children in Bagalkot city and to determine the differences in occlusal characteristics in the same children by age and sex. Materials and methods: A total of 1000 school going children between the age group of 12 to 14 years were selected in the study from Bagalkot city of India. All the occlusal parameters, such as molar relation, canine relation, overjet, overbite and crowding and spacing were recorded in a record sheet. The gender and sex difference was evaluated using Chi-square test. Results: According to the classification of Angle, the prevalence of class I, II and III malocclusions was 17.8, 30.1 and 1.6%, respectively. Ideal occlusion was 3.2% where as normal occlusion was 46.8%. An overjet of at least 4 mm or more was present in 15.2 and 7.2% had a reverse overjet. A total of 9.2 had an increased overbite and 10.6% had open bite. Conclusion: Highly significant (p < 0.001) age differences were found for overjet, overbite and highly significant (p < 0.001) gender differences were found for crowding and spacing. Clinical significance: The study gives the prevalence of malocclusion amongst 12 to 14 years old in urban Indian population. The data can be used for may research projects and gives us a better understanding of malocclusion in urban Indian population.
