The aim of this study was to identify the relationship between Molar Incisor Hypomineralization (MIH) severity and cavitated carious lesions in schoolchildren. This crosssectional study included 506 schoolchildren selected from public schools. The prevalence and severity of MIH was evaluated using the European Academy of Pediatric Dentistry criteria (EAPD), while the prevalence and severity of caries was evaluated by applying the ICDAS (International Caries Detection and Assessment System). The prevalence of MIH was 42.4%, with a severity of 21.7% mild, 7.7% moderate, and 13.0% severe. Prevalence was 61.6% for incipient lesions and 34.0% for cavitated lesions. The prevalence of ICDAS II ≥4 lesions was higher in schoolchildren with MIH than in those without MIH (55.8% vs. 44.2%, p<0.001). In the multinomial model, children with MIH in the moderate/ severe category were more likely (OR=3.28; CI95% 1.01 - 10.6, p<0.048) to present cavitated lesions. The presence of MIH at mild levels was not associated with cavitated carious lesions. A high prevalence of MIH was observed. Moderate and severe levels of MIH were associated with cavitated carious lesions. To prevent dental caries, it is important to identify MIH in children, particularly in the moderate and severe categories.
本研究的目的是确定学龄儿童中磨牙切牙矿化不全（MIH）严重程度与龋洞性龋损之间的关系。这项横断面研究纳入了从公立学校选取的506名学龄儿童。采用欧洲儿童牙科学会标准（EAPD）评估MIH的患病率和严重程度，同时应用国际龋病检测与评估系统（ICDAS）评估龋病的患病率和严重程度。MIH的患病率为42.4%，其中轻度严重程度为21.7%，中度为7.7%，重度为13.0%。初期龋损的患病率为61.6%，龋洞性龋损的患病率为34.0%。患有MIH的学龄儿童中ICDAS II≥4级龋损的患病率高于未患MIH的儿童（55.8%对44.2%，p<0.001）。在多项模型中，中度/重度MIH的儿童出现龋洞性龋损的可能性更大（OR=3.28；95%CI 1.01 - 10.6，p<0.048）。轻度MIH与龋洞性龋损无关。观察到MIH的患病率较高。中度和重度MIH与龋洞性龋损有关。为预防龋齿，识别儿童中的MIH很重要，尤其是中度和重度类型。
