OBJECTIVES: To measure the self-reported frequency and severity of bullying amongst patients referred for orthodontic treatment and to investigate whether there is a relationship between levels of self-reported bullying, malocclusion and need for orthodontic treatment and an individual's self-esteem and oral health-related quality of life (OHRQoL). DESIGN AND SETTING: Cross-sectional study of an adolescent group referred for orthodontic assessment at three UK hospitals. SUBJECTS AND METHODS: Three hundred and thirty-six participants aged between 10 and 14 years were recruited. Validated questionnaires were used to measure the self-reported frequency and severity of bullying, self-esteem and OHRQoL. Orthodontic treatment need was assessed using IOTN. RESULTS: The prevalence of bullying was 12·8%. Being bullied was significantly associated with Class II Division 1 incisor relationship (P = 0·041),increased overbite (P = 0·023),increased overjet (P = 0·001)and a high need for orthodontic treatment assessed using AC IOTN (P = 0·014).Bullied participants also reported lower levels of social competence (P<0·001),athletic competence (P<0·001), physical appearance related self-esteem (P<0·001)and general self-esteem (P<0·001). Higher levels of oral symptoms (P = 0·032),functional limitations (P<0·001), emotional (P<0·001)and social impact (P<0·001) from their oral condition, resulting in a negative impact on overall OHRQoL (P<0·001),were also reported. CONCLUSIONS: Significant relationships exist between bullying and certain occlusal traits, self-esteem and OHRQoL.
