Abstract

AIM: The enamel defects of Molar-Incisor Hypomineralisation (MIH) share clinical characteristics with hypomineralised second primary molars (HSPM) and hypomineralised primary canines (HPC). The main objective of this study is to determine the prevalence of these entities in a population of patients in a hospital dentistry service. The secondary objectives are to know the number and distribution of lesions, classify them according to their degree of severity and to know which dental surfaces are most affected. METHODS: A cross-sectional and observational prevalence study was carried out over a 32-day period, guided by the diagnostic criteria of the European Academy of Paediatric Dentistry (EAPD) together with the descriptive study of the lesions. Healthy patients between 30–42 months and who had all erupted teeth were included. CONCLUSION: The prevalence of HSPM and HPC varies depending on the population studied. It was observed that SPM were affected more often than PC, with the occlusal and buccal surfaces being the most affected, and the majority of the lesions presenting a low degree of severity.
