Abstract

BackgroundThe study was carried out to determine the prevalence of orthodontic treatment need in children from minority ethnic groups and compare the need to the white population. The second objective was to explore variations in agreement between subjective and objective treatment need in a multiethnic context using the aesthetic component of Orthodontic Treatment Need Index (IOTN AC).MethodsA cross-sectional study in North West London, 14 schools were randomly selected from the 27 schools in the two boroughs of Harrow and Hillingdon. Comparison between objective and subjective treatment need was carried out using IOTN AC index. Clinical orthodontic treatment need was also recorded using the dental health component of Orthodontic Treatment Need Index (IOTN DHC).Results2,788 children were examined and completed the questionnaire. 16% of the study population were already wearing appliances or had finished orthodontic treatment. Of the remaining children; 15% had definite need for treatment using the dental health component of the IOTN. There was no significant variation in the need for orthodontic treatment between different ethnic backgrounds (P > 0.05) whether using the AC or DHC components of the IOTN index. However, poor agreement was detected between professional and subjective assessment of ethnic minority of orthodontic treatment need using IOTN AC index.ConclusionOrthodontic treatment need in children of ethnic minorities does not differ significantly from the vast majority of white children. However treatment need based on aesthetic index continues to vary in all ethnic groups from the professional aesthetic assessment

Highlights

The study was carried out to determine the prevalence of orthodontic treatment need in children from minority ethnic groups and compare the need to the white population
To assess whether the need for orthodontic treatment in ethnic minorities differs from the white population based on the dental health component and on the aesthetic component and, thirdly to test the agreement between normative and perceived need for orthodontic care across all ethnicities
442 children (16%) were undergoing orthodontic treatment during the screening, when recording IOTN AC all children were included to explore the need based on aesthetic grounds irrespective of previous or current orthodontic treatment

Summary

Introduction

The study was carried out to determine the prevalence of orthodontic treatment need in children from minority ethnic groups and compare the need to the white population. The second objective was to explore variations in agreement between subjective and objective treatment need in a multiethnic context using the aesthetic component of Orthodontic Treatment Need Index (IOTN AC). Most orthodontic indices have been primarily based on white populations; this may raise a concern since the demography of the United Kingdom has changed rapidly in the last few decades. To assess whether the need for orthodontic treatment in ethnic minorities differs from the white population based on the dental health component and on the aesthetic component and, thirdly to test the agreement between normative and perceived need for orthodontic care across all ethnicities
