This study aimed to evaluate the impact of dental caries treatment on oral health-related quality of life (OHRQoL) among schoolchildren and the responsiveness of the Child Perceptions Questionnaire (CPQ8-10 ) instrument. Brazilian schoolchildren, 8-10 yr of age, were randomly selected and assigned to two groups--dental caries treatment (DCT) and caries-free (CF)--according to their caries experience [decayed, missing, or filled primary teeth (dmft) and decayed, missing or filled secondary teeth (DMFT) values of ≥ 0]. The CPQ8-10 instrument was administered at baseline and at 4 wk of follow-up (i.e. 4 wk after completion of dental treatment). In the DCT group, increases in CPQ8-10 scores were observed between the baseline and follow-up results. However, longitudinal evaluation of the CF group demonstrated no statistically significant difference in CPQ8-10 scores. Responsiveness of the CPQ8-10 instrument (magnitude of change in CPQ8-10 scores) in the DCT group was greater (effect size >0.7) than in the CF group. The findings of this study show that dental caries treatment has an important impact on OHRQoL of children. The CPQ8-10 was considered an acceptable instrument for longitudinal measurement of changes in OHRQoL.
本研究旨在评估龋齿治疗对学龄儿童口腔健康相关生活质量（OHRQoL）的影响以及儿童感知问卷（CPQ8 - 10）工具的反应性。根据龋齿经历[乳牙龋失补牙数（dmft）和恒牙龋失补牙数（DMFT）值≥0]，随机选取8至10岁的巴西学龄儿童并分为两组——龋齿治疗组（DCT）和无龋组（CF）。在基线期和随访4周时（即牙科治疗完成后4周）使用CPQ8 - 10工具进行评估。在DCT组中，观察到基线期和随访结果之间CPQ8 - 10分数有所增加。然而，CF组的纵向评估显示CPQ8 - 10分数无统计学上的显著差异。DCT组中CPQ8 - 10工具的反应性（CPQ8 - 10分数的变化幅度）大于CF组（效应量>0.7）。本研究结果表明，龋齿治疗对儿童的OHRQoL有重要影响。CPQ8 - 10被认为是纵向测量OHRQoL变化的可接受工具。
