Orthodontic treatment need in higher primary schoolchildren of Central Bengaluru, India

Abstract

Aims and Objective:The aim of this study was to evaluate the orthodontic treatment need in 11–14-year-old schoolchildren of Central Bengaluru, India, using the index of orthodontic treatment need (IOTN) and to analyze the treatment needs between males and females and correlation between the esthetic to aesthetic (AC) and dental health component (DHC) of IOTN.Materials and Methods:The sample comprised 500 schoolchildren (187 females and 313 males) who had not undergone orthodontic treatment. No radiographs, study casts, were used; IOTN was calculated from clinical examination and photographs. The data were analyzed using SPSS 20 IBM version.Results:The results for DHC were as follows: 12% students in no need, 52.5% students in little need, 20.5% students in moderate or borderline, 11.5% students in severe need, and 3.5% students were in the category of very severe need for treatment. On evaluating AC components, 91.6% were in the category of no or little need, 2% students in moderate need, and 6.4% in great need category. Mild positive correlation (r = 0.153) between DHC and AC of IOTN was observed. The difference between the IOTN values of boys and girls was not statistically significant.Conclusions:More than 50% of the population in our study showed little/no need category which undergoes undiagnosed and may not seek dental treatment at right time to prevent the future complications. This study provides baseline data on the need and demand for orthodontic treatment among the sample which is important for planning public orthodontic and dental services.

The Need for Orthodontic Therapy forChildren and Adolescents in the Health Center Mostar According to the IOTN Index

“…With regard to a moderate need for therapy, there were slightly fewer males (23.9%) than females (30%), while in the category of those who needed or necessarily required therapy, there were fewer male (19.5%) than female (26.7%) respondents. Most studies did not find a statistically significant difference in the need for therapy between genders (8,9). By comparison, a study conducted 10 years ago in Bosnia and Herzegovina found a statistical difference between girls and boys according to the dental component of this index (6).…”

The IOTN in latest studies – a literature review

“…Takie właśnie właściwości posiada wskaźnik IOTN, który jest na tyle obiektywny, że pozwala porównać potrzeby lecznicze w zależności od różnych czynników, takich jak np. płeć czy wiek (10,25,40).…”

“…In epidemiological studies on the prevalence of malocclusions and the orthodontic treatment needs, it is essential to use indices that are as little subjective as possible and allow comparisons between different populations (14). The IOTN has such properties, and it is objective enough to compare treatment needs according to various factors, such as gender or age (10,25,40).…”

Pooled prevalence estimates of malocclusion among Indian children and adolescents: a systematic review and meta-analysis

“…The total sample size obtained from 10 primary studies was more than nine thousand [49][50][51][52][53][54][55][56][57][58]. Overall pooled prevalence for any type of treatment need arising from malocclusion was 60.4% (CI 49.2, 71.1).…”
