Prevalence and Associated Factors of Crossbite Malocclusion in Subjects Reporting to A Private Dental Hospital

Abstract

Background: Crossbite is a transverse plane malocclusion that can affect a single tooth or numerous teeth, be bilateral or unilateral, and be anterior or posterior. Aim: To determine the prevalence and associated factors for crossbites among subjects visiting private dental college. Materials and Methods: The case records of patients who came to Saveetha Dental College's OP department for orthodontic treatment were used in this retrospective study. The data on age, gender, type of crossbite and the arch involved in crossbite of the patients was collected and statistical analysis was done. The descriptive statistics and chi square test were performed using SPSS software. Results: In total, 430 people with crossbites took part in the research. Patients with posterior crossbite made up 21% of the total, while those with anterior crossbite made up 79%. The Chi square correlation and the kind and number of teeth implicated in crossbite was not significant (p value >0.05), however the relationship between age and the side of involvement was significant (p value 0.05). There was an association between gender, type of cross bite, and side of cross bite involved (p value <0.05). Conclusion: Adult males had a higher incidence of cross bites than females, and anterior crossbites with unilateral involvement were more common than posterior crossbites.
