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.

Generalized aggressive periodontitis in preschoolers: report of a case in a 3-1/2 year old.

Unlabelled: Destructive forms of periodontal disease in children are uncommon. Severe periodontal destruction can be a manifestation of a systemic disease; however, in some patients, the underlying cause of increased susceptibility and early onset is still unknown.

Objective: To describe an effective therapeutic approach to GeneralizedAggressive Periodontitis (GAgP) in children, based on a 3-1/2 year-old male patient referred to the Hospital due to early loss of incisors, gingivitis, and tooth mobility in his primary dentition.
