Knowledge and management of molar–incisor hypomineralisation amongst dentists in The Netherlands.

Background: Molar–incisor hypomineralisation (MIH) is a frequently encountered dental condition in the clinical setting, and correct diagnosis can influence management outcomes. Aim: To assess the knowledge of and attitudes towards the management of MIH amongst dentists in the Netherlands. Design: The study was conducted as a cross‐sectional web survey. The questionnaire used included questions regarding respondent characteristics, awareness, knowledge and management of MIH and was distributed through the Royal Dutch Association for Dentistry (KNMT) to a random sample of 900 dentists. Variables were analysed using descriptive statistics, and differences between distinct groups of dentists were tested using the chi‐squared test. Results: Respondents consisted of 76.6% general dental practitioners, 9.1% paediatric dentists and 14.3% differentiated (specialist) dentists, with a 25.6% overall response rate. The majority knew the term MIH and its clinical characteristics, and could distinguish MIH from other enamel defects. Regarding aetiological factors, 76.6% reported a genetic component. In an asymptomatic case, 47.3% reported non‐invasive treatments. In a mild symptomatic case, treatments from non‐invasive to invasive were reported (p <.05). In a severe symptomatic case, the majority reported invasive treatments. Two‐thirds of respondents were interested in further clinical training about MIH. Conclusions: Most respondents knew the term MIH and its clinical characteristics and would like further clinical training about MIH. [ABSTRACT FROM AUTHOR]
