Abstract
INTRODUCTION: With an estimated 878 million cases worldwide in 2015, molar incisor hypomineralization (MIH) is a growing issue. Early detection and management require knowledge and application of good clinical practices. The aim of the study was to evaluate the knowledge, attitudes, and practices of French dentists regarding MIH. METHOD: A self-administered questionnaire was distributed to different groups of practitioners between 30 January and 27 March 2023, including members of the French dental practice-based research network, members of the social network "French pediatric dentists," and members of the professional social network LinkedIn (LinkedIn, Sunnyvale, California, United States). The data from 311 questionnaires were analyzed. RESULTS: Around 277 (89%) practitioners were familiar with MIH, 180 (58%) were perfectly aware of the clinical features of MIH, and 193 (62%) reported being able to clinically identify MIH. Nearly 100% (310) of dentists cited "environmental pollutants" as the most frequent etiological factor. Glass ionomer is the most used restorative material. CONCLUSION: Education regarding MIH must be improved among dentists to correctly detect, treat, or refer patients. It would seem useful to carry out an MIH prevalence study in France.
