Prevalence and factors related to malocclusion, normative and perceived orthodontic treatment need among children and adolescents in Bangladesh

Abstract

Objective: The purpose of the present study was to assess the prevalence of normative and perceived orthodontic treatment need in schoolchildren and adolescents, related risk factors, and children/parent’s aesthetic perception, compared to orthodontist’s opinion, in Dhaka city, Bangladesh. Methods: A random sample of 800 schoolchildren aging 11-15 years was selected from different schools in the city of Dhaka, Bangladesh. The Dental Health Component (DHC) and Aesthetic Component (AC) of the Index of Orthodontic Treatment Need (IOTN) were assessed as normative treatment need. The Decayed, Missing, Filled Teeth (DMFT) index was used to record caries experience. Children were interviewed on the perception of orthodontic treatment need. Parents also completed a questionnaire on the perception of their child’s orthodontic treatment need, assessed by AC/ IOTN. Results: According to the DHC/IOTN, only 24.7% were in the category of definite need (grade 4-5) for orthodontic treatment. A significant difference was found between the clinician/children and clinician/parents perceived AC score of IOTN (p= 0.0001). Multiple logistic regression showed children with a higher DMFT were significantly more likely to need orthodontic treatment, according to the DHC of IOTN. Conclusion: A low proportion of schoolchildren needs normative orthodontic treatment in the city of Dhaka, Bangladesh. Children with a higher DMFT score were significantly more likely to need orthodontic treatment, according to the DHC of IOTN.

“…40 Besides, lower results were reported in Brazil (20.0%) 41 and Bangladesh (24.7%). 21 The difference between our study and others might be due to the ethnicity difference and the use of variable criteria for the classification of the malocclusion.…”

“…[15][16][17][18][19] In Africa, the prevalence of class-I malocclusion was 89%. 20 The prevalence of malocclusion was 24.7% in Malaysia, 21 and 23.7% in Ethiopia. 22 An institutionbased cross-sectional study in children in Southwest Ethiopia found a high prevalence of Overjet (30.8%) and Crowding (23.3%).…”

Effects of scanning parameters reduction in dental radiographs on image quality and diagnostic performance: A randomised controlled trial

“…The demographic data from the current study were in agreement with a study conducted in Singapore, where 55.9% of participants were female (Tan et al, 2019). In Dhaka, Bangladesh, the same trend of gender distribution can also be observed, where about 50.4% of the total number of participants were female (Sultana and Hossain, 2019).…”
