Dentin Dysplasia: A Review

Objectives Dentin dysplasia (DD) is a rare disorder, which is not accentuated in dental practice. DD has 2 types. Type I is manifested by tooth mobility, short roots, reduced pulp space and normal crowns. Type II or coronal DD is characterized by normal crowns in permanent teeth but discolored crowns in primary teeth. Denticles are detectable in the pulp chamber of teeth in type II DD. Many uncertain aspects of this condition include its etiology, diagnosis, and treatment planning. For a long time, extraction of mobile teeth was the main possible choice, which would lead to psychosocial problems that needed psychological interventions. The present study aimed to collect and classify the recent information on DD. Methods An electronic search of the literature was carried out in PubMed and Google Scholar from 1977 to 2018. Duplicates were eliminated and the retrieved articles and relevant textbooks were thoroughly reviewed. Results Although DD has an unknown etiology, it is known for a fact that it has a hereditary trait. The present article provides some information about DD, including possible etiological factors, clinical, radiographic and histological manifestations, diagnosis and current treatment options. Conclusion Management of DD is based on preservation of teeth in the oral cavity and may vary from preventive and piecemeal care to tooth extraction and regenerative pulp therapy.
