Abstract

OBJECTIVES

The objectives were to investigate the prevalence of the condition, by using transillumination, in a group of children. Analysed the prevalence with regard to gender, jaw affected, and the teeth that exhibited dysplasia most commonly.

METHODS

A sample of 550 children aged 6 to 14 years was selected at the Department of Paediatric Dentistry at the Universitat Internacional de Catalunya, but among those selected only 505 children were eligible for inclusion in the study. The gender and age of the child, number of permanent teeth, number of teeth affected by MIH and their position were registered.

RESULTS

Ninety patients (17.85%) had MIH. Of these, 45 were girls (50%) and 45 were boys (50%). A total of 8062 permanent teeth were observed. Of these, 344 (4.2%) were affected by MIH. Of the teeth affected, 198 (57.7%) were located in the maxilla and 146 (42.4%) in the mandible. This result was statistically significant (P = 0.003).

CONCLUSIONS

The population studied showed a prevalence of MIH of 17.8%. The presence of the defect did not differ according to sex in this population. Defects were more common among teeth in the maxilla.

摘要

目的

通过透照法，调查一组儿童的患病情况。分析性别、受影响的颌骨以及最常见表现出发育不良的牙齿的患病率。

方法

在西班牙加泰罗尼亚国际大学的儿科牙科系选择了 550 名 6 至 14 岁的儿童作为样本，但在这些被选中的儿童中，只有 505 名符合纳入研究的条件。记录了儿童的性别和年龄、恒牙数量、受 MIH 影响的牙齿数量及其位置。

结果

90 名患者（17.85%）患有 MIH。其中，45 名是女孩（50%），45 名是男孩（50%）。共观察到 8062 颗恒牙。其中，344 颗（4.2%）受 MIH 影响。受影响的牙齿中，198 颗（57.7%）位于上颌，146 颗（42.4%）位于下颌。这一结果具有统计学意义（P=0.003）。
