Tooth transposition is a disorder in which a permanent tooth develops and erupts in the normal position of another permanent tooth. Fusion and gemination are developmental disturbances presenting as the union of teeth. This article reports the nonsurgical retreatment of a very rare case of fused teeth with transposition. A patient was referred for endodontic treatment of her maxillary left firs...

BACKGROUND A 16-years old female patient was referred to our observation in July 2006, 14 days after an accident, with traumatic intrusive luxation of the right upper central incisor that caused the nasal floor and buccal cortical bone fracture. While the extraoral examination showed the traumatic lesions of the upper lip, the intraoral examination revealed intrusive luxation, pain and high mob...

O ne of the most critical elements in endodontic treatment is proper tooth isolation. With the exception of teeth that have undergone a traumatic event and remain intact, teeth requiring endodontic treatment fall into one of the following categories: previously restored, carious, fractured or a combination of the three (Figure, A). Before starting endodontic treatment, it is important to remove...

OBJECTIVES The aim of this study was to assess the clinical outcomes achieved with Computer-Assisted Design/Computer-Assisted Manufacturing implant abutments in the anterior maxilla. MATERIAL AND METHODS Nineteen patients with a mean age of 41 (range form 26 to 63) years, treated with 21 single tooth implants and 21 Computer-Assisted Design/Computer-Assisted Manufacturing (CAD/CAM) abutments ...

The junctional epithelium (JE) adheres to the tooth surface, and seals off periodontal tissues from the oral environment. This incompletely differentiated epithelium is formed initially by the fusion of the reduced enamel organ with the oral epithelium (OE). Two proteins, odontogenic ameloblast-associated (ODAM) and amelotin (AMTN), have been identified in the JE. The objective of this study wa...

statement of the problem removal of impacted third molars is the most common oral surgical procedure. many investigators have questioned the necessity of removal in patients who are free of symptoms or associated pathologies. there are currently no data on the prevalence of impacted teeth and associated pathologies in the hamadani population. purpose the aim of this study was to assess the stat...

Double primary teeth were observed in 367 children and their relationship with the permanent successors was studied with the aid of radiographs. Double primary teeth involving 2 adjacent teeth and those involving the same tooth have different patterns of association with the permanent successors. Double primary teeth involving 2 adjacent teeth are associated more frequently with congenitally mi...

Placement of endosseous implants has made it possible to perform restorations in patients who are fully or partially edentulous (1, 2, 20, 21). Original protocols required the placement of implants into healed edentulous ridges. In 1989, Lazzara (44) placed implants at the time of tooth extraction. Immediate implants were augmented with barrier membranes to preserve ridge width and height and t...

the developmental abnormality of tooth resulting from the infolding of enamel/dentin into the root is called dens invaginatus. management of such cases is usually challenging due to the morphological complexity of root canal system. this report presents a rare treatment protocol of a clinical case of oehler’s type iii dens invaginatus combined with an endodontic lesion in a vital maxillary late...
