INTRODUCTION The aim of this study was to determine the effect of different luting agents on fracture resistance of endodontically treated teeth restored with casting post. MATERIALS AND METHODS In this experimental study, forty extracted human maxillary central incisors teeth with the mean length of 23mm were randomly assigned in to four groups. All the studied teeth were caries free without...

instrument fracture within the root canal during root canal treatment is an unwanted and frustrating complication. the fractured segment may hinder cleaning and shaping procedures with potential impact on prognosis of treatment. fracture of endodontic instrument often results from incorrect use or overuse. if breakage occurs clinically, the patient should be informed of the incident and conside...

Vertical root fracture(VRF) is one of the common reasons for extraction of endodontically treated teeth. Though many options of saving such teeth were available, they were not of much success. Therefore the objective of this article is to discuss one such case. A 50 year old male patient reported with Vertical root fracture and 15 mm of periodontal probing depth in the distal aspect of 14. Radi...

Objective: Introduction of fiber-reinforced composites (FRC) greatly enhanced the restoration of fractured anterior teeth. The purpose of this study was to assess the effect of fiber reinforcement on fracture resistance of incisal edge composite restorations of variable thicknesses. Methods: Forty extracted sound human maxillary incisors were divided into four groups of 10. Incisal reduction wa...

this case report describes the multidisciplinary management of subgingival horizontal crown–root fracture of an immature permanent maxillary central incisor in a 10-year-old boy. after removal of the fractured fragment, pulpotomy was performed within 48 h from the injury to promote apexogenesis. the tooth was orthodontically extruded until the fracture line was located above the alveolar bone l...

statement of problem: it is yet unclear whether fiber-reinforced composite posts can enhance the mechanical properties and prevent vertical fractures of teeth under chewing loads. purpose: the purpose of this study was to compare the fracture resistance and failure mode of endodontically treated teeth restored with three different post systems. materials and methods: thirty-six maxillary canine...

Fractured roots were examined histologically, using different stains, to study the morphological fracture patterns and to identify potential irritants. Fractures were usually, but not always, complete and extended from a surface to include the root canal. The potential irritants identified in both the fracture space and communicating canal were bacteria, necrotic tissue, food debris, and uniden...

AIM The aim of the present study was to evaluate the effect of three methods of composite fiber placement along with siloranebased composite resin on cuspal deflection and fracture strength of root-filled maxillary premolars. MATERIALS AND METHODS Mesio-occluso-distal cavities were prepared in 60 extracted premolars subsequent to endodontic treatment. The remaining thickness of buccal and lin...

objective: loss of tooth structure due to dental caries and cavity preparation can reduce fracture resistance, especially in endodontically treated teeth. the aim of the present study was to evaluate fracture resistance of pulpotomized primary molar teeth restored with extensive multisurface amalgam restorations. materials and methods: eighty extracted carious human primary molar teeth were sel...
