Abstract

Background: Molar incisor hypomineralization (MIH) has been recognized as a global dental disorder and concern about this pathology is growing among clinicians around the world.

Objectives: This study aimed to investigate the knowledge and perception of Yemeni dental practitioners in the city of Sana'a in relation to diagnosis, etiological factors and management of MIH.

Materials and Methods: A questionnaire modified from similar previous studies was distributed to 311 Yemeni dentists providing oral health care in Sana'a city. The survey consists of two parts, the first is the demographic-occupational variables that was collected for the participants and the second part included questions related to perception of the diagnosis, possible etiological factors, severity of the condition and management, and the participants ’willingness for advance training in relation to MIH.

Results: The overall response rate is (90%). The majority of respondents came across MIH in their practices (GDPs= 83.2%, SDPs= 90%).Yellow / brown demarcation is feasible as a common clinical symptom. The composite resin was the most used restorative material. The genetic factor was the most specific etiological factor. Most GDPs were significantly uncertain in the diagnosis of MIH compared to SDPs (P = 0.003). Most of the respondents (72.5%) had a low level of knowledge regarding MIH. Participants support the need to assess MIH occurrence and conduct clinical training.

Conclusion: Molar incisor hypomineralization (MIH) is a common dental problem faced by dental practitioners in Sana'a City who have required clinical training regarding diagnosis, etiological factors and MIH management.
