Conhecimento e percepções de cirurgiões-dentistas sobre hipomineralização molar-incisivo.

Abstract

Molar-incisor hypomineralization (MIH) is defined as a developmental defect of the attached enamel that affects the first permanent molars and is often associated with the permanent incisors. This study aimed to evaluate the knowledge and perception of dentists about molar-incisor hypomineralization. This is a quantitative and cross-sectional study carried out with dentists working in Ceará. In addition, questions with clinical photos for differential diagnosis with other enamel defects were included. A total of 104 dentists completed the sessions. Most professionals (82.7%) stated that they assist children in their clinical practice. In addition, a significant portion (83.7%) answered that they knew what HMI is. Of the participants who claimed to know, most (81.4%) had contact with the topic in theoretical classes. Of the total participants, more than 60% believe that genetic factors are involved in the etiology of MIH. Only 7 participants responded that they felt “very confident” to carry out the diagnosis of MIH, while most professionals (41.3%) considered themselves “little confident”. Enamel hypoplasia was the most cited clinical condition (62.5%) as being particularly difficult to distinguish from MIH. Most professionals (53.8%) responded that they had treated patients with MIH in clinical practice. Participants reported knowing the HMI, pointed out clinical characteristics related to this disorder, however, the vast majority did not feel enthusiastic about making the diagnosis, denoting the need for greater dissemination and teaching on the subject.
