The objective of this study was to assess the negative impact of dental caries on the OHRQoL of 8- to 10-year-old Brazilian children.
This population-based case-control study involved 546 children (8-10 years old), 182 cases with a high negative impact on OHRQoL and 364 controls with a low negative impact on OHRQoL. Children's OHRQOL was measured using the Child Perceptions Questionnaire (CPQ8-10). Cases and controls (1x2 ratio) were individually matched by school and gender. Dental caries experience, malocclusion, and traumatic dental injuries were used as independent variables. Dental examinations were carried out at school during daytime hours by two calibrated examiners (Kappa = 0.93-interexaminer and 0.95- intraexaminer). The data were analyzed by descriptive statistics, conditional bivariate and multiple logistic regression, with the significance level set at 5%.
There was no significant difference in traumatic dental injuries and malocclusion between the case and control groups (p>0.05). Children with DMFT/dmft ≥3 had a 2.06-fold (95%CI = 1.28-3.31, p = 0.003) greater chance of experiencing a high negative impact on OHRQoL than those with DMFT/dmft = 0.
Children with high dental caries experience are more likely to present a high negative impact on OHRQoL than those with no dental caries experience.
本研究的目的是评估龋齿对8至10岁巴西儿童口腔健康相关生活质量（OHRQoL）的负面影响。
这项基于人群的病例对照研究纳入了546名儿童（8至10岁），其中182例对OHRQoL有高度负面影响，364例对OHRQoL有低度负面影响。使用儿童感知问卷（CPQ8 - 10）来测量儿童的OHRQoL。病例和对照（1:2比例）按学校和性别进行个体匹配。将龋齿经历、错牙合畸形和牙外伤作为自变量。由两名经过校准的检查者（检查者间kappa值 = 0.93，检查者内kappa值 = 0.95）在白天于学校进行牙科检查。数据通过描述性统计、条件二元和多元逻辑回归进行分析，显著性水平设定为5%。
病例组和对照组在牙外伤和错牙合畸形方面无显著差异（p>0.05）。与DMFT/dmft = 0的儿童相比，DMFT/dmft≥3的儿童对OHRQoL产生高度负面影响的可能性高2.06倍（95%CI = 1.28 - 3.31，p = 0.003）。
与无龋齿经历的儿童相比，龋齿经历多的儿童对OHRQoL产生高度负面影响的可能性更大。
