OBJECTIVE The purpose of this study was to compare endodontically versus nonendodontically treated teeth with respect to clinical features, including patient age and gender and tooth types of vertical root fractures. STUDY DESIGN A total of 315 consecutive cases of vertical root fracture occurring in 274 Chinese patients during a 1 3-year period were reviewed. Age and gender, as well as tooth...

AIM: The aim of this in vitro study is to determine the push-out bond strength bundle glass fiber post (Rebilda GT) and tapered post). MATERIALS AND METHODS: Twenty freshly extracted human single rooted premolar teeth were used, all endodontically treated, after 24 h from obturation gutta-percha removed leaving 5 mm apically ensure clinically acceptable apical seal. Finally, canals flushed with...

The restoration of endodontically treated teeth is a topic that is extensively studied and yet remains controversial from many perspectives. This article reviews the major pertinent literature on this topic, with an emphasis on major decision-making elements in post placement and restoration of endodontically treated teeth. Recommendations are made for treatment planning, materials, and clinica...

BACKGROUND As per many studies endodontically treated teeth are widely considered to be more susceptible to fracture than vital teeth. Obturation strains and post placement have been a major cause of vertical root fracture. Present study was conducted to compare in vitro fracture resistance after filling with either Gutta-percha or Resilon by lateral condensation techniques in root canals. This...

OBJECTIVES Endodontically treated teeth (ETT) used as abutments for removable partial dental prostheses (RPDPs) have an increased fracture risk as compared to vital abutments. One suggested explanation is that ETT exhibit a lower threshold level for tactile sensitivity than vital teeth. Therefore, this study compared the threshold for tactile sensitivity of vital teeth and ETT in the same indiv...

Preservation of tooth integrity and strength is important for the long-term survival of endodontically treated teeth. Endodontic treatment and post space preparation requires reduction of the remaining supportive tooth structure. Restorative modalities following root canal therapy must provide sufficient strength for the prosthetic material and tooth structures. This article presents seven key ...

Fractured endodontically treated teeth below the gingival margin are often extracted and restored with implants or other prosthetic treatment options in many cases. However, dentists should carefully consider other treatment options for these teeth before deciding on extraction due to the risk of vertical and horizontal bone resorption subsequent to extraction as this resorption will result in ...
