To assess malocclusion and related quality of life among 13- to 19-year-old students in Mysore City.
A total of 900 students aged 13-19 years selected based on multistage stratified random sampling were included in this cross-sectional study. A pre-designed format was used to record the sociodemographic details, oral hygiene practices, personal habits, malocclusion and oral health related quality of life. Malocclusion was assessed using Dental Aesthetic Index (DAI ) and quality of life using Oral Health Impact Profile-14 (OHIP-14). Further, the association between malocclusion and related quality of life was assessed.
Normal or slight malocclusion was seen in 79.2% (n = 713). Definite malocclusion was seen in 12.8%, severe malocclusion in 5.7% and handicapping malocclusion in 2.3% of the subjects. The overall prevalence of malocclusion was found to be 20.8%. Out of the 900 study subjects 46.6% (n = 419) reported that malocclusion had some impact on their oral health related quality of life. The results of logistic regression demonstrated that those with malocclusion experienced a significant impact on quality of life (OR = 16.07, CI = 9.17-28.17).

评估迈索尔市13至19岁学生的错牙合畸形及相关生活质量。
本横断面研究纳入了900名13至19岁的学生，这些学生是基于多阶段分层随机抽样选取的。采用预先设计的表格记录社会人口学细节、口腔卫生习惯、个人习惯、错牙合畸形及口腔健康相关生活质量。使用牙科美学指数（DAI）评估错牙合畸形，使用口腔健康影响程度量表14（OHIP-14）评估生活质量。此外，还评估了错牙合畸形与相关生活质量之间的关联。
79.2%（n = 713）的受试者存在正常或轻度错牙合畸形。12.8%的受试者存在明确的错牙合畸形，5.7%为严重错牙合畸形，2.3%为妨碍性错牙合畸形。错牙合畸形的总体患病率为20.8%。在900名研究对象中，46.6%（n = 419）报告称错牙合畸形对其口腔健康相关生活质量有一定影响。逻辑回归结果表明，有错牙合畸形的人生活质量受到显著影响（OR = 16.07，CI = 9.17 - 28.17）。
