Objective: To assess the prevalence of crossbite among different dentition for orthodontic treatment.
Materials and Methods: 980 subjects (490 men, 490 women) aged 5-45 years were evaluated to determine the prevalence of
crossbite in a South Indian population. The patients were classified accordingly into 3 dentition stages (primary, mixed and
permanent), unilateral or bilateral crossbite, anterior or posterior cross bite. The results were obtained and analysed using
SPSS version 22.

significant association between the type of crossbite and gender, with posterior crossbite more commonly in females,
Conclusion: An increasing prevalence of crossbite was observed from the primary dentition towards permanent dentition in
