The aim was to examine the relationship between orthodontic treatment need and Oral Health-Related Quality of Life (OHRQoL) among Lithuanian adolescents aged 11⁻18 across gender and age groups. A representative cross-sectional study of 911 adolescents aged 11⁻18 (mean (M) = 15.53; Standard Deviation (SD) = 1.52) was conducted in 26 public schools. The schoolchildren completed the Child Perceptions Questionnaire to evaluate their OHRQoL. The Index of Orthodontic Treatment Need (IOTN) was used to evaluate the severity of malocclusion. The strength of association between variables was evaluated via negative binomial regression estimating the ratio of sum score means (RSSM). A worse OHRQoL score was associated with a higher grade of IOTN; however, only the Emotional and Social wellbeing domains were significantly affected by malocclusion (RSSM = 1.158; 95% Confidence Interval (CI): 1.083⁻1.237 and RSSM = 1.205; 95% CI: 1.114⁻1.304, respectively). The significant association was identified only among females (RSSM = 1.264; 95% CI: 1.176⁻1.359). A significant association was observed in all age groups for Emotional and Social well-being domains but only in the oldest age group for Oral Symptoms and Functional Limitations domains.
Malocclusion has a negative impact on the OHRQoL of young people with emotional and social aspects being the most affected. Girls and older adolescents suffered from malocclusion more than boys and their younger counterparts.
研究立陶宛 11-18 岁青少年在不同性别和年龄组中，正畸治疗需求与口腔健康相关生活质量（OHRQoL）之间的关系。采用横断面研究方法，对 26 所公立学校的 911 名 11-18 岁青少年（平均年龄（M）=15.53，标准差（SD）=1.52）进行了代表性研究。采用儿童感知问卷（Child Perceptions Questionnaire）评估儿童 OHRQoL，采用正畸治疗需求指数（Index of Orthodontic Treatment Need，IOTN）评估错牙合畸形严重程度。采用负二项回归评估变量之间的关联强度，估计总分均值比（ratio of sum score means，RSSM）。结果显示，OHRQoL 评分越差，IOTN 等级越高；但仅情绪和社交健康维度受到错牙合畸形的显著影响（RSSM=1.158，95%置信区间（CI）：1.083-1.237 和 RSSM=1.205，95%CI：1.114-1.304）。这种显著关联仅在女性中存在（RSSM=1.264，95%CI：1.176-1.359）。在所有年龄组中，情绪和社交健康维度均存在显著相关性，但在年龄较大的组中，口腔症状和功能受限维度也存在显著相关性。
错牙合畸形对年轻人的 OHRQoL 有负面影响，情绪和社交方面受影响最大。女孩和年龄较大的青少年比男孩和年龄较小的青少年更容易受到错牙合畸形的影响。
