Molar-incisor hypomineralisation (MIH) is a global dental problem, yet little is known about the knowledge of the general dental practitioners (GDPs) and dental nurses (DNs) regarding this defect in South East Asia.
To assess and compare the knowledge of the GDPs and DNs in Malaysia regarding the frequency of occurrence of MIH within their practice, its diagnosis, putative aetiological factors and management.
Study design and methods
A questionnaire was distributed to GDPs and DNs during a nationwide dental conference in Melaka, Malaysia and who were asked to answer questions about demographic variables, knowledge, attitudes and practices in the management of MIH.
Descriptive statistics and bivariate analysis were performed. A 5 % level of statistical significance was applied for the analyses.
A response rate of 58.2 % (131/225) was obtained. Most respondents were aware of MIH and encountered it in their practice (GDPs = 82.5 %, DNs = 82.4 %). The condition was observed by respondents less in primary molars compared to first permanent molars. Full agreement between GDPs and DNs did not exist concerning the aetiological factors and management of MIH. Glass ionomer cements were the most popular material used in treating MIH. Most respondents (GDPs = 93 %, DNs = 76.5 %) indicated that they had not received sufficient information about MIH and were willing to have clinical training in the diagnosis and therapeutic modalities of MIH.
MIH is identified and encountered by most respondents. Agreement did not exist between GDPs and DNs concerning MIH frequency of occurrence within their practice, its diagnosis, aetiological factors and management.
