Molar incisor hypomineralisation (MIH) is a significant global health problem frequently encountered by dentists. The aim of this questionnaire-based study was to gain a better understanding of how dentists in the Republic of Ireland perceive and manage MIH. In addition, to compare these findings with results of existing international studies.
Following ethical approval, an online survey was created consisting of 16 questions based on previous surveys regarding perception and treatment of MIH. Photographs and information regarding three specific cases were also included. The questionnaire was distributed by email and the data were analysed using SPSS statistical software.
The total number of respondents was 230, of which 204 were general dentists. The majority of dentists (58%) reported that they observe MIH on a weekly basis. Those dentists exclusively in private practice and respondents aged 36 and older were less likely to note frequent MIH (p = 0.042). The vast majority of respondents felt either confident or very confident in diagnosing MIH (91%). Overall, 71% reported to feel comfortable managing MIH; however, those in private practice only (p = 0.023) and those aged 36 and older (p = 0.011) were less likely to report being comfortable managing MIH. The most commonly cited barrier to care was the child's behaviour, followed by difficulty in achieving local anaesthesia. Composite resin was the most commonly selected material used to restore teeth affected by MIH (84%). In the scenario on cavity design, the results showed a similar number of dentists selected the most conservative and the most aggressive preparation indicating a disparity among choices.
MIH is frequently encountered by Irish general dentists. The overall wide disparity of responses is in line with other studies, and further highlights the need for the development of strong treatment guidelines and continuing dental education to assist dentists in treatment planning for MIH.
磨牙切牙矿化不全（MIH）是全球范围内牙医经常遇到的一个重大健康问题。这项基于问卷调查的研究旨在更好地了解爱尔兰共和国的牙医如何看待和处理MIH。此外，将这些结果与现有国际研究的结果进行比较。
在获得伦理批准后，创建了一项在线调查，该调查由16个基于先前关于MIH认知和治疗的调查的问题组成。还包括三个具体病例的照片和信息。问卷通过电子邮件分发，并使用SPSS统计软件对数据进行分析。
总共有230名受访者，其中204名是普通牙医。大多数牙医（58%）报告称他们每周都会遇到MIH。那些仅从事私人执业的牙医以及36岁及以上的受访者较少注意到频繁出现的MIH（p = 0.042）。绝大多数受访者对诊断MIH感到有信心或非常有信心（91%）。总体而言，71%的受访者报告称对处理MIH感到得心应手；然而，仅从事私人执业的牙医（p = 0.023）和36岁及以上的牙医（p = 0.011）报告称对处理MIH感到得心应手的可能性较小。最常提到的护理障碍是儿童的行为，其次是难以实现局部麻醉。复合树脂是用于修复受MIH影响牙齿的最常用材料（84%）。在窝洞设计的情景中，结果显示选择最保守和最激进预备方式的牙医数量相近，这表明选择存在差异。
爱尔兰普通牙医经常遇到MIH。总体反应的广泛差异与其他研究一致，进一步凸显了制定强有力的治疗指南和持续牙科教育以协助牙医进行MIH治疗计划的必要性。
