Abstract

PURPOSE

The purpose of this study was to evaluate the prevalence of and relationship between hypomineralized second primary molars (HSPM) and hypomineralized primary canines (HPC) with molar-incisor hypomineralization (MIH) in 1,963 schoolchildren.

METHODS

The European Academy of Paediatric Dentistry (EAPD) criterion was used for scoring HSPM/HPC and MIH. Only children with four permanent first molars and eight incisors were considered in calculating MIH prevalence (n equals 858); for HSPM/HPC prevalence, only children with four primary second molars (n equals 1,590) and four primary canines (n equals 1,442) were considered. To evaluate the relationship between MIH/HSPM, only children meeting both criteria cited were considered (n equals 534), as was true of MIH/HPC (n equals 408) and HSPM/HPC (n equals 360; chi-square test and logistic regression).

RESULTS

The prevalence of MIH was 14.69 percent (126 of 858 children). For HSPM and HPC, the prevalence was 6.48 percent (103 of 1,592) and 2.22 percent (32 of 1,442), respectively. A significant relationship was observed between MIH and both HSPM/HPC (P<0.001). The odds ratio for MIH based on HSPM was 6.31 (95 percent confidence interval [CI] equals 2.59 to 15.13) and for HPC was 6.02 (95 percent CI equals 1.08 to 33.05).

CONCLUSION

The results led to the conclusion that both hypomineralized second primary molars and hypomineralized primary canines are associated with molar-incisor hypomineralization, because children with HSPM/HPC are six times more likely to develop MIH.

摘要

目的

本研究旨在评估1963名学童中矿化不足的第二乳磨牙（HSPM）和矿化不足的乳尖牙（HPC）与磨牙-切牙矿化不全（MIH）之间的患病率及关系。

方法

采用欧洲儿科牙科学会（EAPD）标准对HSPM/HPC和MIH进行评分。计算MIH患病率时仅纳入有四颗恒牙第一磨牙和八颗切牙的儿童（n = 858）；计算HSPM/HPC患病率时，仅纳入有四颗第二乳磨牙的儿童（n = 1590）和四颗乳尖牙的儿童（n = 1442）。为评估MIH/HSPM之间的关系，仅纳入符合上述两项标准的儿童（n = 534），MIH/HPC（n = 408）和HSPM/HPC（n = 360）的情况亦如此（卡方检验和逻辑回归）。

结果

MIH的患病率为14.69%（858名儿童中的126名）。HSPM和HPC的患病率分别为6.48%（1592名中的103名）和2.22%（1442名中的32名）。观察到MIH与HSPM/HPC均存在显著关系（P<0.001）。基于HSPM的MIH优势比为6.31（95%置信区间[CI]为2.59至15.13），基于HPC的MIH优势比为6.02（95%CI为1.08至33.05）。
