Summaries for Dentin Dysplasia, Type Ii

NIH Rare Diseases : 53 The following summary is from Orphanet, a European reference portal for information on rare diseases and orphan drugs.Orpha Number: 99791Disease definitionDentin dysplasia type II (DD-II) is a rare mild form of dentin dysplasia (DD, see this term) characterized by normal tooth roots but abnormal primary dentition.EpidemiologyPrevalence of DD-II is not known.Clinical descriptionIn DD-II, features of primary dentition resemble those observed in dentinogenesis imperfecta type 2 (DGI-2, see this term) and include amber translucent coloration, bulbous crowns, cervical constriction, tooth attrition, and short constricted roots. Pulp obliteration is also observed. The permanent dentition seems either unaffected (normal teeth morphology and color) or mild radiographic abnormalities are found (thistle tube-shaped pulp chambers and multiple pulp calcifications).EtiologyDD-II is caused by mutations in the DSPP gene (4q21.3) coding for dentin sialophosphoprotein, a precursor for dentin sialoprotein and dentin phosphoprotein which are involved in dentinogenesis.Diagnostic methodsDiagnosis is based on history, clinical examination and radiographic features. Molecular genetic testing can be used to confirm the diagnosis.Differential diagnosisDifferential diagnoses include conditions that have similar clinical or radiographic features to DD such as osteogenesis imperfecta or dentinogenesis imperfecta (see these terms).Genetic counselingDD-2 follows an autosomal dominant pattern of inheritance. There is therefore a 50% chance that a child born to an affected parent will have the condition.Management and treatmentIn the primary dentition, preformed stainless steel crowns on molars may be used to prevent tooth wear and maintain the occlusal vertical dimension. Appropriate care makes it possible to achieve good esthetic appearance and functional performance.PrognosisPrognosis depends primarily on the age of diagnosis and the quality of management.Visit the Orphanet disease page for more resources.

MalaCards based summary : Dentin Dysplasia, Type Ii, also known as dtdp2, is related to dental pulp calcification and dentinogenesis imperfecta. An important gene associated with Dentin Dysplasia, Type Ii is DSPP (Dentin Sialophosphoprotein), and among its related pathways/superpathways are Degradation of the extracellular matrix and ECM-receptor interaction. Affiliated tissues include testes and bone, and related phenotypes are pulp stones and dentinogenesis imperfecta limited to primary teeth

OMIM : 57 Dentin dysplasia type II is a defect of dentin formation in which the clinical appearance of the secondary teeth is normal, but the primary teeth may appear opalescent, similar to teeth affected by dentinogenesis imperfecta. The roots of the teeth are of normal shape and morphologic character. The pulp chambers and root canals of the anterior teeth and the premolars are shaped like thistle tubes because of the radicular extension of the pulp chamber. Most teeth show accumulations of pulp stones in these unusually shaped pulp chambers (summary by Kalk et al., 1998). Also see dentin dysplasia type I (DTDP1; 125400). (125420)

UniProtKB/Swiss-Prot : 75 Dentin dysplasia 2: A dental defect in which the deciduous teeth are opalescent. The permanent teeth are of normal shape, form, and color in most cases. The root length is normal. On radiographs, the pulp chambers of permanent teeth are obliterated, have a thistle-tube deformity and contain pulp stones.
