ABSTRACT
Dentin dysplasia(DD) is a rare autosomal dominant disorder associated with disturbance of the dentin. While the crowns appear clinically normal, on radiography, the pulp spaces appear partially or completely obliterated, with short blunted roots, and multiple periapical radiolucencies affecting the apparently sound teeth. Clinical signs include spontaneous abscess formation or increased tooth mobility which can lead to exfoliation. DD can therefore have a significant impact on the patient's dentition, and treatment is often challenging. Shields' classification of dentin disorders has been recently criticised for failing to consider differential variations and expressions of these disorders. This paper describes a case of a 23-year-old woman with previously undiagnosed DD, who presented with clinical and histological features belonging to several of these diseases, thus highlighting the potential diagnostic challenges faced with Shields' classification.

Dentin dysplasia is a rare hereditary disturbance of dentin formation characterized by a defective dentin development with clinically normal-appearing crowns, severe hypermobility of teeth and spontaneous dental abscesses or cysts. Radiographic analysis shows obliteration of all pulp chambers by pulp stones, short, blunted and malformed or absent roots, peri-apical radiolucencies of noncarious teeth. We present a case of dentin dysplasia type 1d in a 19-year-old boy along with the clinical, radiographic findings of this condition and treatment. There are still many inconclusive issues in the diagnosis and management of patients with dentin dysplasia. The diagnostic features of this rare disturbance will remain incompletely defined until additional cases have been described.

Dentin dysplasia is a defect of dentin development that was classified by Shields as type I and type II. The teeth in dentin dysplasia type I are characterized by normal enamel and abnormal dentin in the crown and root. For that reason, this disorder is characterized by dental caries, early exfoliation of the teeth and, consequently, maxillomandibular bony atrophy. In this report, we present a case of a young girl affected by dentin dysplasia type I, treated with a combination of onlay bone grafting and a sinus lift technique to accomplish implant placement. This case showed that onlay autogenous grafting and a sinus lift technique are well-tested methods of bony augmentation and can be useful in patients with congenital dentin defects, such as dentin dysplasia.

A case report on dentin dysplasia type I, a congenital disease (autosomal dominant gene defect) affecting deciduous and permanent teeth, is depicted including representations of clinical and histological features, X-ray and CT-findings. Therapy includes extraction of all teeth, ectomization of cystic alteration, revision of paranasal sinus. Aesthetic and functional rehabilitation by means of insertion of a complete denture was achieved.
