Molar Incisor Hypomineralization: Awareness among Postdoctoral Dental Residents: A Cross-Sectional Study

Abstract

Background: Molar incisor hypomineralization (MIH) is the presentation of an enamel defect, where incisors and one (or more) molars are affected. Identifying MIH is significant in restoring its visual defect and avoiding pain or other consequences of this condition. The present cross-sectional study aimed to evaluate the awareness, ability, and confidence in identifying MIH among postgraduate residents in the state of Nevada. Methods: This cross-sectional study was conducted among postdoctoral dental residents at the School of Dental Medicine, University of Nevada, Las Vegas. This cross-sectional study used images of cases of MIH and a survey to collect the data. The survey included demographics, educational background, and basic knowledge of MIH. Results: The response rate to the invitation to participate was 91%. The confidence in identifying MIH was 100%, 50%, and 33.3% for pediatric, orthodontic, and general practice residency (GPR). A total of 70% were aware of this anomaly from their predoctoral dental education and indicated the need for further related education. There was 33% confusion with fluorosis and 16.6% with amelogenesis imperfecta. A total of 66.6% of the participants indicated that they require further education relating to MIH. Conclusion: Within the limitations of the present investigation, MIH awareness among the investigated groups varied but was highest amongst the pediatric residents.

Knowledge and Attitudes of a Group of Dental Students in Turkey About Molar Incisor Hypomineralization

“…With regard to this study’s results, all of our students stated that they had difficulty in distinguishing MIH from other dental anomalies, as in similar studies [ 18 , 31 ]. In a study conducted at the University of Nevada School of Dentistry in Las Vegas [ 18 ], postdoctoral dentists reported that they most often confused it with fluorosis, followed by amelogenesis imperfecta, whereas in a similar study in Syria [ 31 ], senior dental students reported that they had the most difficulty distinguishing it from amelogenesis imperfecta and enamel hypoplasia. In our study, the 4 th -year students stated that they confused it with amelogenesis imperfecta and enamel hypoplasia and the 5 th -year students confused it with enamel hypoplasia and amelogenesis imperfecta, respectively.…”

“…This, in turn, leads to poor retentive etching patterns and higher failure rates in adhesive fillings, which, among other factors, makes clinical management of MIH-affected teeth regarding cavity design and material choices a serious issue [ 17 ]. As it is a difficult condition for clinicians to manage, it is crucial for clinicians to develop awareness, identification skills, and knowledge of its treatment to provide efficient and high-quality oral health care to those affected [ 18 ].…”
