Anomalies of enamel, dentin, and other tooth structures can be influenced by environmental factors that affect differentiation, apposition, and mineralization stages of tooth development. Researchers believe that the dental anomaly Molar Incisor Malformation (MIM) is caused by abnormalities or signal disruptions during the development and formation of enamel and roots. Insults to the central nervous system during the first 1-2 years of life are believed to be the cause of MIM. Seizures, irradiation, brain trauma, meningitis, and spina bifida are some examples of reported disruptions. In this case, the mother of the patient affected by MIM self-reported that he had a history of febrile seizures when he was between the ages of 1-2.
Molar Incisor Malformation is a dental anomaly that affects primary 2nd molars, permanent 1st molars, and permanent central incisors. Typically, the clinical crown of affected teeth appear with normal color and size however, radiographic examination often reveals cervical constrictions, deformed or even obliterated roots. The prevalence of MIM is unknown. In this clinical case, a 10 year old male first presented to the dental clinic with a reported history of pain on his maxillary central incisors and abscesses affecting teeth #8, 9, 24, 25. Radiographs were taken which revealed periapical radiolucencies affecting teeth #8, 9, 24, 25, a lateral radicular cyst on #24, and obliterated roots of #3, 14, 19, 30. This poster will discuss the treatment rendered and future treatment goals.
