An unusual case of molar incisor hypomineralization with a rare combination of fusion, hypodontia, and ankyloglossia in 11-year-old male

Abstract

Molar-incisor hypomineralization (MIH) is a developmentally acquired dental defect that directly affects the enamel and dentin of one to four first molars, frequently associated with affected incisors. Due to alteration in matrix production, crystal arrangement and formation, enamel matrix secretion a compromised enamel structure may be seen. This condition can also be called a idiopathic enamel hypomineralization. In the article, we report a case of 11-year-old male presenting with typical features of MIH affecting all four permanent molars in combination with fusion of mandibular right permanent central and lateral incisor, hypodontia of mandibular left central incisor and ankyloglossia, and a possible management of the clinical condition.
