Dentin dysplasia is a rare disturbance of dentin formation characterized by normal enamel but atypical dentin formation with abnormal pupal morphology. The teeth appear clinically normal in morphologic appearance and color. The teeth characteristically exhibit extreme mobility and are commonly exfoliated prematurely. Radiograph shows obliteration of all pulp chambers, short, blunted and malformed or absent roots with periapical radiolucencies involving apparently intact tooth. This case is reported here because of its rarity along with the description of various clinical, radiological and histological features.

The purpose of this article is to present three cases of a rare phenomenon called pre-eruptive coronal resorption (PCR), which occurs in teeth with enamel degeneration. In the first case, the enamel defects occurred due to ectodermal dysplasia, which represents the first documented case of a patient with ectodermal dysplasia who underwent PCR. In the other two cases, the enamel defects occurred due to amelogenesis imperfecta.

The sulfate transporter gene SLC26A2 is crucial for skeletal formation, as evidenced by its role in diastrophic dysplasia, a type of skeletal dysplasia in humans. Although SLC26A2-related chondrodysplasia also affects craniofacial and tooth development, its specific role in these processes remains unclear. In this study, we explored the pivotal roles of SLC26A2-mediated sulfate metabolism during tooth development.

Dentin dysplasia (DD) is a rare clinical entity that can affect deciduous dentition alone, or both deciduous and permanent dentition. It is a developmental disorder that can be classified as DD type I or type II. This case report describes a rare case of DD type I in a 19-year-old patient, highlighting the clinical presentation and the radiographic features of the condition, confirmed by ground sectioning and microscopic examination of extracted teeth.
