Fusion of teeth is the union of two or more tooth germs, which are usually separated. Depending upon the stage of odontogenesis, it can be complete or incomplete. The present case describes fusion between the maxillary primary right central and lateral incisor with a supernumerary tooth. Clinical and radiographic examination revealed the presence of fused triple teeth. The fused teeth were extr...

Radioprotective agents like selenium are used to reduce the damage caused by radiation in healthy tissues. The aim of this study was to evaluate the effect of sodium selenite on the development of the molars of offspring of rats irradiated during odontogenesis. Twenty pregnant rats were randomly divided into 4 groups: control, irradiated, selenium and selenium/irradiated. The selenium and selen...

Amelogenesis Imperfecta has been defined as a group of hereditary enamel defects not associated with evidence of systemic disease. Restoration for patients with this condition should be oriented toward the functional and esthetic rehabilitation and the protection of these teeth. The specific objectives of the treatment were to enhance esthetics, eliminate tooth sensitivity and restore masticato...

Amelogenesis imperfecta is an autosomal dominant disorder. It is a group of hereditary diseases showing abnormal enamel density and crown malformation. This clinical report describes the oral rehabilitation of a young adult diagnosed with a variant of hypoplastic amelogenesis imperfecta with multiple impacted teeth and skeletal class III malocclusion. The treatment procedures of teeth extractio...

This clinical report describes a male with autosomal recessive generalized hypoplastic amelogenesis imperfecta. This case is unusual in coronal resorptions prior to tooth eruption. This finding has been reported in some cases of autosomal recessive, autosomal dominant and X linked amelogenesis imperfecta (AI). In reported cases, the defects were usually small and occurred in a maximum of 2 teet...

The correct distinction between osteogenesis imperfecta and non-accidental injury (NAI) is an emotive subject upon which the fate of a child can depend. It has been the subject of strongly worded papers and letters by experts. 1-5 Although the frequency, clinical features, and skeletal effects of NAI are not in question, much new knowledge on osteogenesis imperfecta has bypassed the general pae...

BACKGROUND Type V osteogenesis imperfecta is characterized by hyperplastic callus formation and interosseus membrane calcification. CASE CHARACTERISTICS A 16-year-old boy who presented with history of recurrent fractures, had hard persistent swellings at fracture sites, and had radiographic features of hyperplastic callus and interosseus membrane calcification. OUTCOME Sequence analysis of ...

Dentinogenesis imperfecta (DI) is a type of dentin dysplasia that affects the dentin structure of one or both dentitions, which may be classified in three types. The aim of this report was to show the clinical and radiographic features of the four cases of DI in the same family group. Five brothers were checked clinically and radiographically. Two individuals were diagnosed, by their phenotypic...

We report the progressive otic capsule demineralization around the membranous labyrinth and facial nerve in an adult patient with osteogenesis imperfecta tarda. Whereas the initial CT scan showed bandlike, undermineralized pericochlear areas, 2 years later, repeat CT performed because of hearing deterioration showed progression of these findings to the promontory, the round window niche, and th...
