A case of molar-incisor hypomineralization with genetic and environmental influences

Abstract

Background: Molar-Incisor Hypomineralization (MIH) is a common childhood dental pathology. This paper describes a case with familial involvement and environmental risk factors. Case Description: A 35-year old female has yellowish-brown opacities present on central and lateral maxillary incisors, right and left maxillary canines, right and left maxillary first molars, and right and left maxillary second molars. A 33-year old male sibling has yellowish-brown opacities on the right and left central and lateral maxillary incisors. The male sibling’s fraternal twin does not have evidence of MIH. A maternal grandmother also had evidence of MIH, though involved teeth are not known. Practical Implications: MIH is a condition with both genetic and environmental components. Practitioners should consider both etiologies when patients present with the condition.
