Prevalence and Clinical Presentation of Molar Incisor Hypomineralisation Among School Children in Chennai, India

Abstract

Background:Molar incisor hypomineralization is the term for hypomineralization of one to four first permanent molars with or without concurrent involvement of the permanent incisors (MIH). Aim: This study's objective is to evaluate the incidence of MIH and its clinical manifestation among schoolchildren in Chennai, India. Materials and Methods:The sample size for this study included 54 participants, ranging in age from 7 to 17.The diagnostic standards suggested by EAPD were applied. According to how serious the flaws were, MIH was divided into three categories: mild, moderate, and severe. Results and Discussion: Therefore the results showed that MIH had moderate prevalence (46.1%) among the subjects.With p values of 0.01 and 0.05, respectively, the connection of sex with tooth and prevalence was significant. Females (51.85%) were more to MIH than males (48.15%) among the 11-17 years age group.  Conclusion: Therefore, it can be concluded that the severe clinical presentation of MIH highlights the need to gain knowledge on prevalence and clinical occurrence in school children.
