Hypomineralised second primary molar (HSPM) is a developmental enamel defect associated with dental caries.
To evaluate the impact of HSPM on oral health-related quality of life (OHRQoL) in preschoolers through hierarchical analysis.
This population-based cross-sectional study assessed 834 5-year-old preschoolers, in Teresina, Piauí, Brazil, using sociodemographic questionnaires and Early Childhood Oral Health Impact Scale (ECOHIS). Dental examination was performed by two calibrated examiners (κ ≥ 0.80) for the diagnosis of HSPM (EAPD), dental caries (dmft and pufa indices), and malocclusion (Foster and Hamilton criteria). Analysis of the determinants of OHRQoL was stratified at three levels (P < .05).
Severe HSPM was associated with OHRQoL in bivariate analysis (P < .05). In adjusted final multivariate analysis (model 1), the presence of dental caries with or without clinical consequences was associated with worse OHRQoL (P < .05). In model 2, after the removal of dental caries, preschoolers with severe HSPM had greater probability of having a negative impact on OHRQoL in the child impact section (RR = 2.14; 95% CI = 1.26-3.65), family impact section (RR = 1.99; 95% CI = 1.16-3.42), and total score (RR = 2.09; 95% CI = 1.25-3.49) of the ECOHIS.
Severe HSPM had a negative impact on the OHRQoL of preschoolers and their families, but the presence of dental caries neutralised this impact.
发育性低矿化第二恒磨牙（HSPM）是一种与龋齿相关的牙釉质发育缺陷。
通过层次分析评估 HSPM 对学龄前儿童口腔健康相关生活质量（OHRQoL）的影响。
本基于人群的横断面研究评估了巴西皮奥伊州特雷西纳的 834 名 5 岁学龄前儿童，使用社会人口统计学问卷和儿童早期口腔健康影响量表（ECOHIS）。两名经过校准的检查者（κ≥0.80）进行了牙科检查，以诊断 HSPM（EAPD）、龋齿（dmft 和 pufa 指数）和错畸形（Foster 和 Hamilton 标准）。OHRQoL 决定因素的分析分为三个层次（P<.05）。
在单变量分析中，严重 HSPM 与 OHRQoL 相关（P<.05）。在调整后的最终多变量分析（模型 1）中，存在有或无临床后果的龋齿与 OHRQoL 较差相关（P<.05）。在模型 2 中，在去除龋齿后，严重 HSPM 的学龄前儿童在儿童影响部分（RR=2.14；95%CI=1.26-3.65）、家庭影响部分（RR=1.99；95%CI=1.16-3.42）和 ECOHIS 的总评分（RR=2.09；95%CI=1.25-3.49）上更有可能对 OHRQoL 产生负面影响。
严重 HSPM 对学龄前儿童及其家庭的 OHRQoL 有负面影响，但龋齿的存在减轻了这种影响。
