Özet: Introduction: Molar Incisor Hypomineralization (MIH) is defined as a qualitative defect resulting from the decrease in inorganic content and lack of mineralization in enamel layer of affected tooth. Its characterization is presence of opacities/pores of varying sizes from white to yellowish brown in color. Loss of tooth substance, plaque accumulation, caries formation started and progressed rapidly short after tooth eruption in majority of patients with MIH. Additionally to esthetics and sensitivity problems in patients, it presents treatment challenges for dentists. Therefore, understanding its etiology is important to prevent. Aim: This study aims to raise awareness of etiologic factors related to MIH and to determine necessary measures for prevention. Method: We performed a literature review of potential etiologic factors of MIH, which involve one or more permanent first molars, and may also affect permanent incisors. Results: Limited information is available regarding etiology of MIH. Observational studies have been conducted to determine etiological factors, and diseases occurring postnatally are found more effective considering prenatal/perinatal/postnatal periods. Various factors such as systemic diseases, drug use, malnutrition, preterm birth, low birth weight, long-term lactation, dioxins, and bisphenol A (BPA) have been associated with MIH. Respiratory tract diseases, certain antibiotics, calcium deficiency, and BPA in materials in contact with infants have been particularly emphasized. Genetic factors are also reported by some studies. Conclusion: Further studies are required to determine clear-cut etiologic factors for MIH. Systemic diseases, applied treatments, malnutrition, chemical agents, genetic factors, and other possible conditions occurring during prenatal/perinatal/postnatal periods should be discussed in detail.
