Objective: To determine the association between the oral health-related quality of life (OHRQoL), the need for orthodontic treatment and bullying among Brazilian teenagers. Methods: This was a cross-sectional epidemiological study. To assess the malocclusion, the Dental Aesthetic Index was used. And the Oral Health Impact Profile-14 was used to analyze the OHRQoL. The Kidscape questionnaire was used to investigate cases of bullying. The following variables were also included: previous orthodontic treatment and a desire to fix the teeth to improve one’s appearance. Multivariate analysis was performed using logistic regression considering the poor OHRQoL as a response variable. Results: 815 teenagers participated in the study. There was a statistically significant association between oral health-related quality of life and the variables: previous orthodontic treatment (p= 0.0270), desire to fix the teeth (p【摘要】引言：正畸治疗以口腔健康与功能恢复为核心目标，但心理与社会影响最终成为患者寻求治疗的主要动因。研究目的：探究巴西青少年口腔健康相关生活质量（Oral Health-related Quality of Life, OHRQoL）、正畸治疗需求与欺凌行为之间的关联。方法：本研究为横断面流行病学研究。采用牙齿美观指数（Dental Aesthetic Index）评估错颌畸形，使用口腔健康影响程度量表-14（Oral Health Impact Profile-14, OHIP-14）分析口腔健康相关生活质量，通过Kidscape问卷调研欺凌行为发生情况。此外纳入的变量还包括：既往正畸治疗史、为改善外貌而希望矫正牙齿的意愿。以较差的口腔健康相关生活质量作为因变量，采用逻辑回归进行多因素分析。结果：本研究共纳入815名青少年。口腔健康相关生活质量与以下变量存在统计学意义上的显著关联：既往正畸治疗史（p=0.0270）、牙齿矫正意愿（p
