摘要

背景:第一恒磨牙(FPM)是恒牙列中的第一颗牙齿,在六岁左右出现在口腔中,位于乳牙后面,从而将初级牙列转换为混合牙列。其早期形成是硬牙组织疾病发作的一个危险因素,最常见的是臼齿-切牙矿化度低(MIH)。目的:本研究旨在评估一组罗马尼亚儿童在混合牙列期FPM水平上釉质发育缺陷的矿化度低类型。患者、材料和方法:研究对象为87名患者,44名女性和43名男性,分为以下年龄组:5-6岁、6-7岁、7-8岁、8-9岁、9-10岁、10-11岁、11-12岁和12岁以上。所有儿童都在牙科诊所接受儿科牙医的检查。结果:在受试者中,40.2%的受试者在FPM上表现出低矿化病变。在受影响的儿童中,女孩占62.9%,男孩占37.1%。轻度形式最为普遍,在71.4%的受试者中发现。在受影响的儿童中,22.9%的儿童出现中度形式,5.7%的儿童出现重度形式。MIH患病率随着年龄的增长而显著下降。分别属于8-9岁和10-11岁组的只有两名儿童表现出严重的MIH病变。根据病变的严重程度与年龄的关系,确定了MIH儿童的分布在统计学上的显著差异(p=0.007)。结论:6至7岁的儿童受FPM低矿化的影响最大,这表明需要通过彻底诊断对疾病进行早期管理,以及预防性和拦截性治疗方法。

A clinical and statistical study on enamel hypomineralization of the first permanent molar in the period of mixed dentition.

A clinical and statistical study on enamel hypomineralization of the first permanent molar in the period of mixed dentition.

A clinical and statistical study on enamel hypomineralization of the first permanent molar in the period of mixed dentition.

A clinical and statistical study on enamel hypomineralization of the first permanent molar in the period of mixed dentition.

Background: The first permanent molar (FPM) is the first tooth in the permanent dentition that emerges in the oral cavity, at around the age of six and behind the deciduous teeth, thus converting the primary dentition into a mixed dentition. Its early formation represents a risk factor for the onset of hard dental tissues disorders, the most common being the molar incisor hypomineralization (MIH).

Aim: The aim of the study was to assess the hypomineralization type of developmental defects of enamel at FPM level during the mixed dentition stage, in a group of Romanian children.

Patients, materials and methods: The research was conducted on 87 patients, 44 females and 43 males, divided into the following age groups: 5-6 years, 6-7 years, 7-8 years, 8-9 years, 9-10 years, 10-11 years, 11-12 years and older than 12 years. All children were examined in the dental office by a pediatric dentist.

Results: Of the subjects, 40.2% presented hypomineralization lesions on the FPM. Among the affected children, 62.9% were girls and 37.1% were boys. Mild forms were the most prevalent, being found in 71.4% of the affected subjects. Moderate forms were present in 22.9% and severe forms in 5.7% of the affected children. MIH prevalence significantly decreased with increasing age. Only two children belonging to the group 8-9 years and 10-11 years, respectively, showed severe MIH lesions. Statistically significant differences were determined in what regards the distribution of MIH children according to the severity of the lesions in relation to age (p=0.007).

Conclusions: Children 6- to 7-year-old have been the most affected by FPM hypomineralization, which indicates the need for early management of the disease, through a thorough diagnosis, and preventive and interceptive therapeutic approaches.

期刊介绍: Romanian Journal of Morphology and Embryology (Rom J Morphol Embryol) publishes studies on all aspects of normal morphology and human comparative and experimental pathology. The Journal accepts only researches that utilize modern investigation methods (studies of anatomy, pathology, cytopathology, immunohistochemistry, histochemistry, immunology, morphometry, molecular and cellular biology, electronic microscopy, etc.).
