BACKGROUND: Although numerous studies have documented malocclusion in various age groups
in India, the literature on the prevalence of malocclusion in mixed dentition is scanty. Dental caries
is another most common condition affecting the general health. However, its association with
malocclusion in mixed dentition is not well known.
AIM: The purpose of this study was to establish the prevalence of malocclusion and its association
with caries experience in 8–9‑year‑old children of Davangere city, South Indian region.
SETTING AND DESIGN: The study design was a cross‑sectional survey.
MATERIALS AND METHODS: A total of 800 children from 350 schools (both males and females)
were randomly selected for the study. t‑test and Chi‑square test were used for statistical analysis.
RESULTS: The overall prevalence of malocclusion among 8–9‑year‑old children was 40.9%. The
most prevalent malocclusion was crowding (11.5%), followed by excessive overjet (9.4%), deep
bite (6.8%), spacing (6.5%), crossbite (4.5%), and open bite (3.2%). Class I molar relationship
prevailed in 95.5% of children.
CONCLUSION: The prevalence of malocclusion in our study was in accordance with the other studies
reported in India, which ranged from 19.6% to 90%. Furthermore, correlation of malocclusion and
dental caries in the primary dentition, although nonsignificant, presented children with malocclusion
to have a higher caries experience than children without malocclusion.
