Author(s): Remmiya Mary Varghese*, Sharon Keziah V


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.
Results: The overall prevalence of crossbite was found to be 8:30%. The most common age group affected was 16-30 yrs Old.
Posterior crossbite was more prevalent with 72%. There was a higher frequency of unilateral crossbite. There was a
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
this study.
