Molar Incisor Hypomineralization (MIH) is a dental condition characterized by the underdevelopment of enamel in the molars and incisors. This results in white, yellow, or brown spots on the teeth, making them more susceptible to decay and sensitivity. MIH typically affects the first permanent molars and the permanent incisors, which can lead to aesthetic concerns and functional issues. The exact cause of MIH is not fully understood, but it may be linked to factors such as environmental influences, genetic predisposition, or systemic conditions during tooth development. Early diagnosis and management are essential to prevent further complications and maintain oral health.
