Atypical Developmental Defects of Enamel in Primary Incisors Versus Preeruptive Intracoronal Resorption (PEIR): Case Reports.

Developmental defects of enamel (DDE) in children range from moderate to severe and may predispose to dental fractures and early childhood caries. The prevalence of DDE in the primary dentition range from 24 to 75 percent, and the right time to diagnose DDE should be as soon as the teeth erupt. However, early detection of DDE in primary incisors is difficult because parents seldom visit the dentist at this age and, later on, caries lesions mask the original alteration.
