Molar-incisor Malformation: Two Cases of a Newly Described Dental Anomaly.
Molar-incisor malformation (MIM) is a recently described dental developmental anomaly with marked manifestations in the primary second molars and permanent first molars and sometimes the permanent maxillary central incisors. To date, there are only two known manuscripts that present this anomaly. The major manifestations are severe coronal cervical constriction of the affected molars and significant under-development of one or more roots. These abnormalities may be detected during routine radiographic examination or present as altered or ectopic eruption or early exfoliation. The characteristic radiographic features are sufficient to identify this abnormality properly. The purpose of this paper is to present two cases of MIM and discuss the impact of the dental abnormalities on patient management.
