QDT 2013 Over the last decade, laboratory procedures have changed dramatically due to the introduction of computer-aided design/computerassisted manufacture (CAD/CAM) technology. This evo lu tion began with the use of zirconia as a base material for dental restorations. Recently, the use of CAD/CAM-fabricated full-contour zirconia (FCZ) crowns for posterior teeth has become a popular restoratio...

introduction: perforations of the pulpal floor create problems during endodontic treatment and often results in secondary periodontal involvement with eventual loss of teeth. the purpose of this study was to evaluate the ability of mineral trioxide aggregate (mta), amalgam, zinc oxide and eugenol (zoe) and portland cement to seal furcal perforations in extracted human molars using dye penetrati...

Connated teeth are the consequences of developmental anomalies leading to the eruption of joined elements. Fusion and gemination are terms frequently used to describe the clinical presentation of connated teeth. The terms ‘double teeth’, ‘double formations’, ‘joined teeth’, ‘fused teeth’ or ‘dental twinning’ are often used to describe fusion or gemination, both of which are primary developmenta...

More than forty years after their development, porcelain-fused-to-metal (PFM) restorations remain the clinical standard to which other esthetic dental materials are measured. One of the drawbacks of PFM restorations is the difficulty with making them appear lifelike when viewed adjacent to natural teeth. All-ceramic restorations have become a welcome addition to the restorative armamentarium as...

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...

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 ...

OBJECTIVE To assess the discrepancies in marginal integrity and contact points of Porcelain Fused to Metal (PFM) crowns and its association with caries in adjacent teeth. STUDY DESIGN Cross-sectional study. PLACE AND DURATION OF STUDY Dental Section of the Aga Khan University Hospital, Karachi, from January to August 2009. METHODOLOGY Ninety six (96) patients with PFM crowns on maxillary ...

Successful clinical management of teeth with odontogenic anomalies is quite challenging. Fusion can be defined as a union of two separate tooth buds at some stage in their development. This case report describes a multidisciplinary approach involving endodontic and restorative considerations for a successful, functional and esthetic rehabilitation of fused tooth using cone beam computed tomogra...

Objective. Fusion is a dental anomaly that arises through the union of two adjacent teeth. The case report presents multidisciplinary management of a fused maxillary anterior tooth. Case Report. A 10-year-old boy was referred to the pediatric dental clinic with the chief complaint of a large upper anterior tooth. Intraoral and radiographic examinations indicated fusion between the permanent max...
