Abstract

Purpose: To evaluate perceptions, attitudes, and clinical experience of Brazilian dental practitioners regarding molar incisor hypomineralisation (MIH).

Methods: An online survey with 27 questions, covering professional profile data, perceptions, and knowledge on clinical management of MIH, was employed. Descriptive analyses, chi-square, Fisher's exact, and Cramer's V tests were used.

Results: Sample comprised 100 participants, equally distributed between those working in private or public sectors. Most private sector practitioners had 21-30 years of clinical experience (28%) and master's degree (50%), while most public sector practitioners had 11-20 years of clinical experience (32%) and a PhD degree (32%). Most participants (86%) recognized MIH in their practice. Statistically significant differences were observed in frequency (p = 0.001), incidence (p = 0.039), and lesion type (p = 0.043) between practitioners from both sectors. Uncertainly in management was reported by 49%, mainly in public sector. For mild MIH in incisors, no treatment was chosen (43%), and the treatment longevity was the only significant factor reported (p = 0.012). In cases of mild MIH in first permanent molars (FPMs), 51% of respondents opted to keep the affected tissue and apply fissure sealant. Glass ionomer (GI) restoration was commonly indicated for FPMs with severe MIH with moderate loss of structure and sensitivity (38%). In cases with substantial structural loss and pulpal involvement, the most chosen treatment was endodontic intervention combined with preformed crowns.

Conclusion: Brazilian dental practitioners face MIH in clinical practice. Although, public sector professionals are less confident in diagnosis and treatment, no significant differences in treatment preferences between public and private sector dental practitioners were identified.

巴西牙科医生对臼齿切牙低矿化的看法、态度和临床经验:一项横断面研究。
目的:评估巴西牙科医生对磨牙切牙低矿化(MIH)的看法、态度和临床经验:方法: 采用在线调查的方式,共设置了 27 个问题,涵盖专业概况数据、对 MIH 的看法和临床管理知识。采用描述性分析、卡方检验、费雪精确检验和克拉默V检验:样本由 100 名参与者组成,其中私营和公共部门从业人员各占一半。大多数私营机构从业人员拥有 21-30 年的临床经验(28%)和硕士学位(50%),而大多数公共部门从业人员拥有 11-20 年的临床经验(32%)和博士学位(32%)。大多数参与者(86%)在实践中承认 MIH。两个行业的从业人员在发病频率(p = 0.001)、发病率(p = 0.039)和病变类型(p = 0.043)方面均存在明显的统计学差异。49%的医生表示对治疗方法不确定,主要集中在公共部门。对于门牙轻度MIH,43%的患者没有选择任何治疗方法,而治疗时间的长短是唯一的重要因素(p = 0.012)。对于第一恒磨牙(FPM)的轻度MIH,51%的受访者选择保留受影响的组织并使用窝沟封闭剂。玻璃离聚体(GI)修复通常适用于结构和敏感性中度丧失的重度MIH第一恒磨牙(38%)。在结构严重受损和牙髓受累的病例中,选择最多的治疗方法是牙髓治疗结合预成冠:结论:巴西的牙科医生在临床实践中面临着MIH问题。结论:巴西牙科医生在临床实践中面临着MIH的问题,虽然公共部门的专业人员对诊断和治疗的信心不足,但在治疗偏好方面,公共部门和私营部门的牙科医生没有发现明显的差异。

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.
