Assessment of malocclusion severity and orthodontic treatment needs in 12–15-year-old school children of Namakkal District, Tamil Nadu, using Dental Aesthetic Index

ABSTRACT Objective: The objective of the study is to assess the prevalence of malocclusion and orthodontic treatment needs among 12-15 years old school children of Udaipur, India. Materials and Methods: A cross-sectional descriptive survey was conducted among 887 subjects aged 12-15 years. The prevalence of malocclusion and orthodontic treatment needs was assessed using dental aesthetic index (World Health Organization, 1997). General information on demographic data was also recorded. Chi-square test, analysis of variance and Scheffe′s test were employed for statistical analysis. Results: Malocclusion and orthodontic treatment need was reported among 33.3% of the study subjects. A significant age and gender difference depicting preponderance among younger age group and a male proclivity was experiential. A significant improvement in anterior crowding and largest anterior maxillary irregularity with age was documented. Males had a significantly higher prevalence of anterior crowding, midline diastema and largest anterior maxillary irregularity than females. Conclusions: The prevalence of malocclusion and orthodontic treatment needs among school children of Udaipur city, Rajasthan, India was found to be 33.3%.A significant age and gender difference was observed in prevalence of malocclusion, crowding and largest anterior maxillary irregularity. Midline diastema showed a significant gender difference. The baseline information outlined in the present study can be appropriately utilized for the future planning to meet the orthodontic treatment need among the population.

Objectives: To assess the severity of malocclusion and orthodontic treatment needs among 12- to 15-year-old school children of Davangere District, India, by using the Dental Aesthetic Index (DAI).Methods: A descriptive cross-sectional study was conducted among 1800 12- to 15-year-old school children of Davangere District, Karnataka, India. Talukas (administrative units in some states in India) were considered clusters. Schools were selected using simple random sampling procedures. The 300 study subjects were selected using systematic random sampling procedures. Data consisting of DAI components were recorded pro forma. The collected data were subjected to statistical analysis. The Chi-square test (X2) was used to compare malocclusion severity. The analysis of variance (ANOVA) test was used to compare the changes in DAI scores and the mean DAI scores between age groups. The Z test was used to compare mean DAI scores between the 2 sexes and between children residing in urban and rural areas.Results: Of the 1800 school children examined, 899 (49.9%) were boys and 901 (50.1%) were girls. Most of the children (79.9%) had DAI scores ≤ 25 with no or minor malocclusion requiring no or little treatment, 15.4% had DAI scores of 26–30 with definite malocclusion requiring elective treatment, 4.2% had DAI scores of 31–35 with severe malocclusion requiring highly desirable treatment, and 0.5% had DAI scores ≥ 36 with handicapping malocclusion requiring mandatory treatment.Conclusions: The majority of the children in our study (79.9%) required no or little treatment; 20.1% had definite malocclusion requiring definite orthodontic treatment.

ABSTRACT Introduction Oral health care in rural areas is limited due to shortage of dental manpower, financial constraints and the lack of perceived need for dental care among rural masses. Aim and Objectives To assess malocclusion and orthodontic treatment needs among 12 and 15 years old rural school children in Kancheepuram district. Materials and Methods Multistage random sampling methodology was employed for the selection of blocks, village panchayats, schools and school children. The final sample size of the study is 1000 which included 500 children from 12 years and 500 from 15 years. The malocclusion was recorded using Dental Aesthetic Index. Results The overall prevalence of malocclusion among both the age groups was 75%. The mean DAI score among the 12 years was 29.1 ± 6.02 and among the 15 years was 28.2 ± 5.45 respectively. Conclusion The results of this study indicate that there is high prevalence of malocclusion among the rural school children.
