OBJECTIVES The objective of this study was to evaluate stress distribution in the dentin and alveolar bone created by load application on simulated endodontically treated teeth with two different esthetic posts. MATERIALS AND METHODS A finite element model was made and elastic moduli and poissons ratio of all the materials fed to the software. For both the models, a 100N force was applied on ...

The goal of dentistry is to preserve functional dentition to promote the general health, longevity, and productivity of the horse; however, throughout recorded equine dental history, exodontia has been the primary treatment for diseased teeth. This treatment predisposes the equine dentition to subsequent periodontal disease, malocclusion, and additional tooth loss. Restorative dentistry is the ...

Introduction: The restoration of endodontically treated teeth is a topic that has been studied extensively but it is still a challenge for dental practitioners. The aim of this study was to evaluate fracture resistance, fracture patterns and fracture location of endodontically treated human maxillary premolars restored with direct and indirect composite resin and ceramic restoration. Methods: E...

BACKGROUND Adhesive systems, resin composites, and light curing systems underwent continuous improvement in the past decade. The number of patients asking for ultraconservative treatments is increasing; clinicians are starting to reevaluate the dogma of traditional restorative dentistry and look for alternative methods to build up severely destroyed teeth. PURPOSE The purpose of this study wa...

Objective. Determination of the effect of dentin bonding agent (DBA) on the prevention of tooth discoloration produced by mineral trioxide aggregate (MTA). Methods. 50 teeth were endodontically treated and after removal of 3 mm of obturating materials were divided into five groups. In white MTA (WMTA) and grey MTA (GMTA) groups, these materials were placed in root canal below the orifice. In DB...

The anatomic anomalies detection is important for an attentive clinician. Asuccessful treatment of an endodontically involved tooth should make itfunctional and aesthetically acceptable for the patient. The following articlepresented a case of gemination and the endodontic, prosthetic and periodontaltreatments which were done to keep a complicated tooth in aesthetic zone

When a method of intracoronal reinforcement is selected, many factors must be weighed. The hazards include (1) the induced stresses and the risk of fracture during placement of the dowel, (2) the probability of root perforation during post space preparation, (3) the wedging action of tapered dowels, and (4) the incidence of fracture with self-threading pins in devitalized teeth. The amount of t...

Décembre 2000, Vol. 66, No 11 613 There is no consensus on the best procedure for restoring endodontically treated teeth. However, retrospective studies1-6 do identify factors that affect the success rate. Tooth location in the arch,1-3 type of occlusion,2 amount of remaining dentin3 and type of abutment1 affect the selection of a restorative approach that will produce a favourable outcome. Yet...

STATEMENT OF PROBLEM There are few published studies analyzing the effects of different ferrule lengths of endodontically treated teeth in relationship to newly developed fiber-reinforced and zirconia dowel systems. PURPOSE This in vitro study compared the effect of 3 different ferrule lengths on the fracture resistance and fracture patterns of crowned endodontically treated teeth restored wi...
