Evaluate the impact of the premature loss of primary molars due to caries on oral health-related quality of life (OHRQoL) in schoolchildren.
A cross-sectional study was conducted with children eight to ten years of age at public schools in the city of Florianópolis selected through cluster sampling. The collection of the clinical data occurred in the school setting by four trained and calibrated examiners (Kappa > 0.7) DMFT/dmft index, PUFA/pufa index, accentuated overjet, and anterior open bite. Sex and age of the child and guardian's schooling (classified as ≤ 8 or > 8 years) were collected through a questionnaire answered by the guardians. OHRQoL was assessed using the Child Perceptions Questionnaire 8-10. The data were submitted to bivariate, multivariate, and hierarchical Poisson analyses.
A total of 1456 children participated in the study. The prevalence of premature tooth loss due to caries was 5.8% (n = 85). The prevalence of negative impact on OHRQoL was 47.4% (n = 691). Negative impact on OHRQoL was significantly associated with the premature loss of primary molars (p < 0.001) as well as the sex (girls), guardian's schooling (> 8 years) and the presence of untreated caries (p < 0.001).
The premature loss of primary molars due to caries was associated a negative impact on the OHRQoL of children eight to ten years of age. Negative impact is also associated with untreated caries, sex, and the level of schooling of guardians.
评估因龋齿导致乳牙过早缺失对学龄儿童口腔健康相关生活质量（OHRQoL）的影响。
采用整群抽样法，对弗洛里亚诺波利斯市公立学校8至10岁的儿童进行横断面研究。由四名经过培训且校准合格的检查人员（卡帕值>0.7）在学校环境中收集临床数据，包括DMFT/dmft指数、PUFA/pufa指数、明显的前牙深覆盖和前牙开颌。通过监护人填写的问卷收集儿童的性别、年龄以及监护人的受教育程度（分为≤8年或>8年）。使用儿童感知问卷8 - 10评估OHRQoL。数据进行双变量、多变量和分层泊松分析。
共有1456名儿童参与研究。因龋齿导致的乳牙过早缺失患病率为5.8%（n = 85）。对OHRQoL产生负面影响的患病率为47.4%（n = 691）。对OHRQoL的负面影响与乳牙过早缺失（p < 0.001）、性别（女孩）、监护人的受教育程度（>8年）以及未治疗的龋齿（p < 0.001）显著相关。
因龋齿导致的乳牙过早缺失与8至10岁儿童的OHRQoL负面影响相关。负面影响还与未治疗的龋齿、性别以及监护人的受教育程度有关。
