Abstract

Aim: Molar-incisor hypomineralization (MIH) is a developmental enamel defect that presents diagnostic and treatment challenges for dental professionals. Understanding the knowledge, perception, attitude, practice, and awareness of MIH is essential for improving its management in pediatric dentistry. This systematic review evaluates the knowledge, perception, attitude, practice, and awareness of MIH among dentists and dental students. Methods: A systematic search was conducted across PubMed, Scopus, ScienceDirect, Web of Science, EBSCO, and Google Scholar following PRISMA guidelines. Cross-sectional studies were included, and the methodological quality was assessed using the Joanna Briggs Institute (JBI) checklist. Results: Out of 2499 identified articles, 38 met the inclusion criteria, comprising 11,129 participants. Data collection was primarily conducted via Email (44.73 %), Google Forms (31.57 %) and direct questionnaire (15.78 %). Most studies assessed knowledge (89.47 %), followed by perception (60.52 %), practice (47.36 %), attitude (34.21 %), and awareness (10.52 %). Pediatric dentists demonstrated higher levels in all domains. Conclusion: The findings indicate a need for improved education and training on MIH. Dental institutions and regulatory bodies may use this informati-on to enhance curricula and clinical guidelines, promoting better MIH management in pediatric dentistry. © 2025 Elsevier B.V., All rights reserved.
