Background and Aim: There have been attempts to restore destroyed primary anterior teeth using a variety of post and core systems, which were able to solve just part of the problems related to this issue. Therefore, the present study aimed to inves-tigate the fracture resistance of restorations supported with a variety of posts and cores in primary anterior teeth. Materials and Methods: The pr...

One year following root canal treatment and internal etching and bleaching of anterior teeth in dogs, the animals were sacrificed and the teeth prepared for stereomicroscopic or light microscopic examination. Evidence of cervical root resorption and ankylosis was noted on several teeth. The bleaching factors associated with the teeth exhibiting resorption were heat with 30% hydrogen peroxide. R...

Advances in the technology of bonding porcelain to enamel created the possibility of porcelain veneers as an alternative to the use of full crowns for the treatment of many clinical conditions, such as treatment of diastemas, malaligned teeth, worn dentition, chipped teeth, and excessively discolored teeth. Veneers are considered to be a more conservative treatment approach than full crowns bec...

BACKGROUND Tooth extraction is associated with dimensional changes in the alveolar ridge. The aim was to examine the effect of single versus contiguous teeth extractions on the alveolar ridge remodeling. MATERIAL AND METHODS Five female beagle dogs were randomly divided into three groups on the basis of location (anterior or posterior) and number of teeth extracted - exctraction socket classi...

Supernumerary teeth can present in various forms and in any region of the mandible or maxilla, but have a predisposition for the anterior maxilla. It is a developmental anomaly and has been argued to arise from multiple etiologies. A hyperactive dental lamina where the localized and independent hyperactivity of dental lamina is the most accepted cause for the development of the supernumerary te...

the technique described below offers temporary crown for the severely damaged vital anterior teeth without resorting to emergency root canal therapy or pin.
