The dentin dysplasias (DD), which may be classified as type I (DD1) or type 2 (DD2), form a group of rare, inherited abnormalities that are clinically distinct from dentinogenesis imperfecta. Studies of affected families may help to distinguish different types of DD and provide further insight into their etiology and clinical management. This report describes a family that showed characteristic...

introduction: intrinsic tooth discolorations after endodontic treatment are principally attributed to the composition of necrotic pulp tissue, hemorrhage within the pulp cavity, endodontic medicaments and/or filling materials. residual sealer left in pulp chamber after obturation can cause discoloration. the objective of this in vitro study was to evaluate coronal discoloration created by ah26 ...

Schimmelpenning syndrome (SS) is characterised by specific skin manifestations, skeletal defects, and central nervous system abnormalities. Here, the SS is briefly reviewed, and the oral and dental manifestations are described in a patient whose medical findings were previously published and included severe hypophosphatemic rickets. Significant oral and dental features included papillomatous le...

The case of a 3 11/12-year-old Chinese boy with the dental abnormalities of "otodental" dysplasia is reported. Hearing was normal. Dental anomalies consisted of delayed eruption of globe-shaped molars, bulbous deciduous canines, and double pulp chambers in the molars. Radiographs taken 4 years later showed taurodontic molars, supernumerary microdontic teeth, retarded formation of premolars, and...

INTRODUCTION Hypophosphatemic rickets represents a group of heritable renal disorders of phosphate characterized by hypophosphatemia, normal or low serum 1,25 (OH)2 vitamin D and calcium levels. Hypophosphatemia is associated to interglobular dentine and an enlarged pulp chambers. AIM Our goal was to verify the dental abnormalities and the oral health condition in these patients. MATERIAL A...

Fusion of either primary or permanent molars is rare. Fusion can be either partial or complete, depending on the developmental stage of the teeth when the fusion began. This paper reports a case of unilateral fusion of maxillary primary molars associated with an adjacent succedaneous supernumerary permanent tooth. Three studies have reported primary double molars associated with syndromes. Two ...
