dentinogenesis imperfecta/lamyropsis

Dentinogenesis imperfecta (DGI) and dentin dysplasia (DD) are allelic disorders that primarily affect the formation of tooth dentin. Both conditions are autosomal-dominant and can be caused by mutations in the dentin sialophosphoprotein gene (DSPP, 4q21.3). We recruited 23 members of a

According to their phenotypic features, the hereditary dentin defects in humans are categorized in two major classes: dentinogenesis imperfecta and dentin dysplasia. At its turn, the dentin dysplasia is subdivided in dentin dysplasia type I and dentin dysplasia type II, a milder clinical

The dentin sialophosphoprotein (DSPP) gene on chromosome 4q21.3 encodes the major noncollagenous protein in tooth dentin. DSPP mutations are the principal cause of dentin dysplasia type II, dentinogenesis imperfecta type II, and dentinogenesis imperfecta type III. We have identified a DSPP splice

Dentin dysplasia, type II (MIM*125420) is an autosomal dominant disorder of dentin development. Clinically the primary dentition appears opalescent, and radiographically the pulp chambers are obliterated, resembling dentinogenesis imperfecta. However, unlike dentinogenesis imperfecta, the permanent

Orthopantomograms of 49 patients with osteogenesis imperfecta (OI) classified according to Sillence were examined for dysplastic dentin defects and other developmental abnormalities of the teeth. Thistle-tube-shaped pulps in the permanent teeth were observed in five patients. Four of them had pulp
