Introduction Molar Incisor Hypomineralization (MIH) represents a significant developmental disturbance of enamel that poses considerable challenges in pediatric dental practice worldwide. This condition, characterized by qualitative defects in the enamel of one or more first permanent molars, often with associated involvement of permanent incisors, is a prevalent issue affecting children globally.1 Its impact extends beyond mere structural compromise, frequently leading to increased susceptibility to dental caries, pronounced hypersensitivity, aesthetic concerns, and potential psychosocial effects on affected children.1The International Journal of Dental Science and Innovative Research (IJDSIR) functions as an international, open-access, and peer-reviewed platform dedicated to disseminating high-quality research and innovative discoveries across various disciplines within dental sciences, including pediatric dentistry.9 Given the journal's emphasis on innovative research and its prior publications related to MIH11, a comprehensive review of current management strategies for MIH in pediatric dentistry is highly relevant. This article aims to consolidate the existing knowledge regarding MIH, covering its definition, prevalence, etiology, clinical characteristics, and diagnostic methods. It will then explore the diverse range of preventive, desensitizing, and restorative interventions available to clinicians. Furthermore, this review will highlight emerging technologies and suggest future research directions to optimize long-term outcomes for children. Discussion Effective management of MIH requires a thorough understanding of its characteristics, etiology, and the various clinical approaches available. Characteristics and Etiology of MIH MIH is characterized as a qualitative enamel defect of systemic origin, presenting as demarcated Hypomineralization that affects at least one first permanent molar and frequently involves permanent incisors.1 The global prevalence of MIH shows considerable variation, ranging from 2.8% to 40.2%, with notable regional differences.1 This wide range in reported prevalence may stem from inconsistencies in diagnostic criteria and the influence of diverse environmental and genetic factors.1 The precise etiology of MIH remains complex and multifactorial, involving a combination of systemic, genetic, and environmental elements.1 Factors suggested to predispose individuals to MIH include: Prenatal and Perinatal Influences: Maternal illnesses during pregnancy, certain medication use, radiation exposure, stress, smoking, premature birth, low birth weight, and birth hypoxia.1 Postnatal Factors: Childhood illnesses, particularly those occurring within the first three years of life, high fevers, the use of antibiotics (especially penicillin and amoxicillin), and infantile eczema.1 Other Contributing Elements: Environmental toxins, such as dioxins and polychlorinated biphenyls (PCBs) and nutritional deficiencies. Clinical Manifestations and Diagnosis MIH presents with several distinct clinical features: Demarcated Opacities: These are clearly defined areas of discolored enamel, varying from white or cream to yellow or brown, often localized to the cuspal or incisal third of the affected tooth.1 Yellow-brown defects Dr. Madhur Nitin Mutha, et al.
