Dentinogenesis Imperfecta type 2 case report 13 years of follow-up

Abstract

Introduction: Dentinogenesis Imperfecta is a hereditary pathology that severely affects dentin mineralization and affects both dentitions. Clinically it is characterized by translucent and opalescent teeth surfaces. Radiographically, the teeth show an altered crown shape, partial or total obliteration of the pulp chambers, with short roots. Functionally, there may be sensitivity and premature teeth loss. Case report: The aim is to present a case of Dentinogenesis Imperfecta with 13 years of follow-up. The clinical study showed color alterations in both dentitions with translucent, grey to brownish teeth. In some of the controls the primary molars showed enamel fractures and dentin exposure. Radiographic controls showed in both dentitions, total obliteration of pulp chambers and root canals with short roots. The family genogram and histopathological study of an exfoliated primary tooth, which reported dysplastic dentin compatible with Dentinogenesis Imperfecta type 2, are presented. At the functional level, she was sensitive to eating. Treatment was preventive and minimally invasive. Conclusions: The characteristics of this pathology and the treatments carried out are described in order to guide pediatric dentists on the need for early diagnosis and periodic follow-up in order to adopt appropriate therapeutic measures to avoid further sequelae in these young patients.
