Abstract

PURPOSE

To determine the prevalence of molar-incisor hypomineralization (MIH) in children and possible factors associated with this disorder.

METHODS

This was a cross-sectional observational study of 594 11- to 14-year-olds from Teresina, Piauí, Brazil. The diagnosis of MIH was made based on criteria set by the European Academy of Pediatric Dentistry. To investigate possible associated factors, mothers completed a questionnaire. A descriptive analysis of the data, chi-square, Mann-Whitney, and Fisher tests and Poisson regression (PR) were performed.

RESULTS

The prevalence of MIH was 18.4 percent (95 percent confidence interval [CI] equals 15.20 to 21.50). The maxillary molars were the teeth most affected by MIH (36.1 percent). MIH patients showed a higher number of mean DMF-T (PR equals 2.18; 95 percent CI equals 1.46 to 2.85) than those not affected by the condition. There was an association between MIH and preterm birth (PR equals 1.76; 95 percent CI equals 1.22 to 2.12) and between MIH and respiratory distress at birth (PR equals 1.83; 95 percent CI equals 1.25 to 2.18).

CONCLUSIONS

The prevalence of MIH in schoolchildren was 18.4 percent. Those with MIH had a greater mean DMF-T than those without MIH. Preterm birth and respiratory distress were associated with MIH.

摘要

目的

确定儿童磨牙-切牙矿化不全（MIH）的患病率以及与该疾病相关的可能因素。

方法

这是一项对来自巴西皮奥伊州特雷西纳市的594名11至14岁儿童进行的横断面观察性研究。MIH的诊断基于欧洲儿童牙科学会设定的标准。为调查可能的相关因素，母亲们填写了一份问卷。对数据进行了描述性分析、卡方检验、曼-惠特尼检验、费舍尔检验和泊松回归（PR）分析。

结果

MIH的患病率为18.4%（95%置信区间[CI]为15.20至21.50）。上颌磨牙是受MIH影响最严重的牙齿（36.1%）。与未受该疾病影响的患者相比，MIH患者的平均龋失补牙面数（DMF-T）更高（PR = 2.18；95% CI为1.46至2.85）。MIH与早产之间存在关联（PR = 1.76；95% CI为1.22至2.12），MIH与出生时呼吸窘迫之间也存在关联（PR = 1.83；95% CI为1.25至2.18）。
