Knowledge and Perceptions on Molar Incisor Hypomineralization among Dental Students in Indonesia

Challenges in managing Molar incisor hypomineralization (MIH) are still apparent. The knowledge and perception of MIH among dental students in Indonesia is currently unknown. This study aimed to analyse knowledge and perception in undergraduate clinical stage and paediatric dentistry postgraduate dental students in Indonesia. A cross-sectional study was conducted by disseminating a self-administered questionnaire about knowledge and perceptions among dental students in four dental schools in Indonesia. Chi-square tests and t-tests were employed to analyse the data. A total of 145 students, 83 undergraduate students and 62 postgraduate students completed the online questionnaire. There was a statistically significant difference in knowledge score between undergraduate and postgraduate students (p<0.05), with scores of 45.1±6.6 and 51.2±5.4 respectively. Most postgraduate students (88.7%) knew that the caries pattern related to MIH is different to the classic caries pattern. Nonetheless only 42.2% of undergraduate students knew. Undergraduate students (67.5%) were unconfident and very unconfident in treating MIH. Almost all students in both groups would like to have further training about MIH. Knowledge and perceptions on MIH still need to be improved. MIH shall be included in the undergraduate curriculum to increase the knowledge, perception, and confidence in managing MIH
