How Anterior Crossbite Severity Relates to Appearance-Based Bullying in School-Age Children: Evidence from the ROMA...

This study examined the prevalence of anterior crossbite in school-age children, investigated the frequency of appearance- related bullying, and determined whether crossbite severity correlates with bullying exposure among children aged 8-12 years.

A cross-sectional study involved 2,080 children from public schools in Damascus, using random cluster sampling.Anterior crossbite and other occlusal issues were assessed using the ROMA Index. Dental appearance-related bullying was evaluated using a modified Olweus Bully/Victim Questionnaire; children reporting bullying two or more times monthly were classified as victims.Bullying types-teasing, name-calling, social exclusion, and physical aggression-were documented along with occurrence settings. Severity scores were calculated by summing numerical codes for each bullying type. Relationships between occlusal characteristics and bullying were analyzed using Chi-square tests, Cramer's V, and logistic regression, adjusting for age and gender.

Of 2,080 children aged 8 to 12 years, 19.6% had anterior crossbite, and 34.4%reported dental appearance-related bullying. Multivariable binary logistic regression revealed that all forms of malocclusion, particularly those involving an anterior crossbite, were associated with a significantly higher likelihood of experiencing bullying (p < 0.001), and that bullying intensity increased proportionally with crossbite severity. Teasing and mockery emerged as the most common forms of victimization. Although specific patterns of bullying exhibited considerable variability across different occlusal traits (p < 0.001), the locations where these incidents occurred-primarily in school playgrounds-did not reveal significant differences among the various groups (p = 0.120).

Anterior crossbite severity serves as a meaningful correlate for appearance-based bullying in children, extending beyond simple dental concerns. Incorporating crossbite severity screening into school-based prevention programs offers a practical strategy to address both oral health and psychosocial well-being in childhood.
