Background: Molar Incisor Hypomineralization (MIH) is a developmental enamel defect affecting at least one first permanent molar, often accompanied by incisor involvement. It poses diagnostic and therapeutic challenges and may affect the quality of life. This study aimed to assess the knowledge, attitudes, and performance of dental professionals across specialties regarding MIH.
Materials and Methods: This cross-sectional study was conducted in 2024 among 311 dental specialists and residents in Isfahan, Iran. Data were collected using a validated questionnaire covering knowledge, attitude, and performance. The mean scores for participants' knowledge, attitudes, and performance were assessed and reported. The data was analyzed with Chi-square test, independent t-test, and one-way ANOVA (α = 0.05).
Results: The study achieved a response rate of 90.93%, with 98.5% of participants having previously managed patients with MIH. The mean knowledge, attitude, and performance scores were 12.65 ± 2.69 (out of 18), 46.24 ± 3.89 (out of 65), and 13.00 ± 2.85 (out of 20), respectively. Knowledge levels differed significantly across specialties (p = 0.005), with pediatric dentists scoring the highest. Attitude also varied significantly among specialists (p = 0.002), with orthodontists showing the lowest scores. Performance scores were significantly different between groups (p < 0.001), with pediatric dentists performing best.
Conclusion: There is a high prevalence of MIH in all lines of specialty. The overall knowledge level was considered high, with the highest scores achieved by pediatric dentists. The attitude was generally positive, and the overall performance of the participants was relatively desirable, particularly among pediatric dentists.
