To evaluate the impact of the first six months of orthodontic treatment with fixed appliances on the oral health-related quality of life (OHRQoL) of adolescents, comparing boys and girls, using a specific condition questionnaire.
Cross-sectional.
School of Dentistry of the Federal University of Minas Gerais, Belo Horizonte, Brazil.
Adolescents aged 10-17 years.
Forty-six adolescents participated in this study. Adolescents' OHRQoL was evaluated using the Brazilian version of the questionnaire Impact of Fixed Appliances Measure. This questionnaire comprises 43 questions distributed across nine domains: aesthetics; functional limitation; dietary impact; oral hygiene impact; maintenance impact; physical impact; social impact; time constraints; and travel/cost/inconvenience implications. The answer options follow the Likert scale, in the range of 1-5. A higher score indicates a more negative impact on the OHRQoL. Adolescents' malocclusion was assessed using the Dental Aesthetic Index. Information on family income, adolescents' age and tooth extraction was also collected. A directed acyclic graph was used to identify potential confounders. Statistical analysis involved the chi-square test, the Student's test and the analysis of covariance. The minimal clinically important difference was also calculated.
Of the 46 participants, 25 were girls and 21 were boys. The female adolescents presented a more negative impact from the orthodontic treatment on the quality of life when compared to the male adolescents ( < 0.001), regardless of the influence of the confounding variables. The most negative repercussions were identified in the domains of oral hygiene ( = 0.002), physical impact ( < 0.001) and social impact ( < 0.001).
The impact of the first six months of orthodontic treatment on OHRQoL is more negative in female individuals than in male individuals. The results of this study may be useful for the oral healthcare provider during the counselling of adolescents undergoing fixed appliance therapy.
使用特定情况问卷，评估固定矫治器正畸治疗的前六个月对青少年口腔健康相关生活质量（OHRQoL）的影响，并比较男孩和女孩。
横断面研究。

10 - 17岁的青少年。
46名青少年参与了本研究。使用巴西版的固定矫治器影响测量问卷评估青少年的OHRQoL。该问卷包含43个问题，分布在九个领域：美观；功能限制；饮食影响；口腔卫生影响；维护影响；身体影响；社会影响；时间限制；以及旅行/成本/不便影响。答案选项采用李克特量表，范围为1 - 5。分数越高表明对OHRQoL的负面影响越大。使用牙科美学指数评估青少年的错牙合情况。还收集了家庭收入、青少年年龄和拔牙的信息。使用有向无环图来识别潜在的混杂因素。统计分析包括卡方检验、学生t检验和协方差分析。还计算了最小临床重要差异。
46名参与者中，25名是女孩，21名是男孩。与男性青少年相比，女性青少年在正畸治疗对生活质量的影响方面表现出更负面的影响（P < 0.001），无论混杂变量的影响如何。在口腔卫生（P = 0.002）、身体影响（P < 0.001）和社会影响（P < 0.001）领域发现了最负面的影响。
正畸治疗的前六个月对OHRQoL的影响在女性个体中比男性个体更负面。本研究结果可能对接受固定矫治器治疗的青少年进行咨询时的口腔医疗保健提供者有用。
