Abstract

Purpose: The aim of the present was to assess the association between MIH and tooth agenesis (TA) in orthodontic patients from the Federal University of Rio Grande do Norte, Natal, Brazil.

Methods: A cross-sectional study was performed to evaluate the presence of MIH and TA in a sample of 371 pretreatment orthodontic records from patients aged 9-18 years. Statistical analyses were performed using the Chi-square and Fisher's exact tests, and logistic regressions.

Results: There was a statistically significant association between the prevalence of tooth agenesis and MIH. A higher percentage of third molar agenesis, maxillary premolar agenesis, and mandibular second premolar agenesis was observed among children with MIH-affected teeth. Patients with MIH had a 2.43 times greater chance of third molar agenesis, and a 5.88 times higher likelihood of mandibular premolar agenesis.

Conclusion: There is a weak association between MIH and TA. Furthermore, the presence of hypomineralised molars increases the risk of tooth agenesis.

臼齿门牙矿化不足与牙齿缺失之间的关系：一项针对巴西儿童和青少年的横断面研究。

目的：本研究旨在评估巴西纳塔尔北里约格朗德州联邦大学正畸患者中MIH与牙齿缺失（TA）之间的关联：方法：我们进行了一项横断面研究，对 371 名 9-18 岁正畸患者的正畸前记录样本中是否存在 MIH 和牙齿缺失（TA）进行了评估。研究采用卡方检验、费雪精确检验和逻辑回归进行统计分析：结果：在统计学上，牙齿缺失的发生率与MIH之间存在明显的关联。在受MIH影响的儿童中，第三磨牙缺失、上颌前磨牙缺失和下颌第二前磨牙缺失的比例较高。MIH患者第三磨牙缺失的几率是正常人的2.43倍，下颌前磨牙缺失的几率是正常人的5.88倍：结论：MIH与TA之间存在微弱关联。此外，臼齿矿化不足会增加牙齿缺失的风险。

期刊介绍： The aim and scope of European Archives of Paediatric Dentistry (EAPD) is to promote research in all aspects of dentistry for children, including interceptive orthodontics and studies on children and young adults with special needs. The EAPD focuses on the publication and critical evaluation of clinical and basic science research related to children. The EAPD will consider clinical case series reports, followed by the relevant literature review, only where there are new and important findings of interest to Paediatric Dentistry and where details of techniques or treatment carried out and the success of such approaches are given.
