Abstract

Objective: To evaluate whether the presence of molar-incisor hypomineralization (MIH) is associated with a greater number of decayed teeth in schoolchildren.

Methodology: A cross-sectional study was conducted with a random sample of 347 children aged from seven to ten years in the Brazilian city of Diamantina. The International Caries Detection and Assessment System (ICDAS) criteria were used to determine the number of teeth with moderate/extensive caries (ICDAS codes 3-6). MIH was assessed according to the criteria of the European Academy of Paediatric Dentistry (EAPD). Sociodemographic data and data regarding children's habits were obtained via a questionnaire sent to parents/guardians. Descriptive analyses, Mann Whitney and Kruskal Wallis tests, and Poisson regression were performed.

Results: The prevalence of MIH was 20.5% and that of moderate/extensive caries was 39.2%. The mean number of teeth with moderate/extensive caries was 1.80 (SD±2.67). The mean number of decayed permanent teeth was 0.69 (SD=1.21), and the mean number of decayed primary teeth was 1.11 (SD=1.89). The number of teeth with moderate/extensive caries was associated with the presence of MIH in children (PR=1.45; 95% CI=1.03-2.04; p=0.031). Furthermore, the number of teeth with moderate/extensive caries was associated with lower monthly family income, high frequency of sugar consumption, and visible plaque (p<0.05).

Conclusion: The presence of MIH is associated with a greater number of decayed teeth in schoolchildren.

Clinical relevance: This study suggests that children with MIH are at higher risk of developing caries, emphasizing the importance of specific preventive care and early treatments for this condition. This can influence clinical practices, public health policies, and parental education.

在7 - 10岁的巴西学童中,臼齿-门牙低矿化与龋齿病变之间是否存在关联?横断面研究。
目的:探讨学童磨牙-门牙低矿化(MIH)是否与大量蛀牙有关。方法:对巴西迪亚曼蒂纳市347名年龄在7至10岁之间的儿童进行了横断面研究。采用国际龋齿检测和评估系统(ICDAS)标准确定中/广泛性龋齿的牙齿数量(ICDAS代码3-6)。根据欧洲儿科牙科学会(EAPD)的标准对MIH进行评估。社会人口统计数据和有关儿童习惯的数据是通过发给父母/监护人的问卷获得的。描述性分析、Mann Whitney和Kruskal Wallis检验和泊松回归。结果:MIH患病率为20.5%,中/广泛性龋患病率为39.2%。中/广泛龋的平均牙数为1.80颗(SD±2.67)。恒牙平均龋数为0.69颗(SD=1.21),乳牙平均龋数为1.11颗(SD=1.89)。儿童中/广泛龋的牙数与MIH的存在相关(PR=1.45;95%可信区间= 1.03 - -2.04;p = 0.031)。此外,患有中度/广泛龋病的牙齿数量与较低的家庭月收入、高的糖消费频率和可见的牙菌斑有关(结论:MIH的存在与学童中更多的蛀牙有关)。临床意义:本研究提示MIH患儿发生龋齿的风险较高,强调了对这种情况进行特殊预防护理和早期治疗的重要性。这可能影响临床实践、公共卫生政策和父母教育。
