This study evaluated the effects of 10% alphatocopherol on the fracture resistance of endodontically treated teeth subjected to tooth bleaching with hydrogen peroxide and immediately restored with composite resin. Fifty bovine incisors were selected, including 10 sound teeth that constituted the control group (G1 (C)). The remaining 40 teeth, which were endodontically treated, were divided into...

OBJECTIVES The present study was set up to explore (1) a potential association between a person's caries risk profile and the presence or absence of root-filled teeth, and (2) the caries risk in endodontically treated teeth. STUDY DESIGN Two hundred Saudi adults were divided into an Endodontic Group (EG; n = 100), with a minimum of 2 root-filled teeth, and a Non-Endodontic Group (NEG; n = 100...

Pulpitis results in significant morbidity among the elderly, particularly in underserved communities. We collected panoramic oral radiographs from 244 (mean age 67) participants of the Northern Manhattan Study, a prospective cohort study of stroke risk in a multiethnic urban population. Radiographs were evaluated for missing teeth, caries, restorations, periodontal bone loss, adequacy of endodo...

This paper aims at evaluating the mechanical performance of endodontically treated teeth. A threedimensional "nite element analysis of teeth is presented. The stress distribution in the teeth restored with a few variants of posts is compared. An improved design of the post is presented. A study on alternative materials for posts has been reported. Conclusions on the ideal shapes and materials o...

The aim of this study was to compare the resistance of endodontically treated teeth with intraradicular retainer different amounts of remaining coronal structure. Fifty freshly extracted maxillary canines were endodontically treated and randomly assigned to five groups (n=10), as follows: group 1 (control) = teeth with custom cast post and core; group 2 = teeth without remaining coronal structu...

OBJECTIVE This study evaluated the fracture strengths of endodontically treated teeth restored with prefabricated posts with different post lengths. MATERIAL AND METHODS Thirty freshly extracted canines were endodontically treated. They were randomly divided into groups of 10 teeth and prepared according to 3 experimental protocols, as follows; Group 1/3 PP: teeth restored with prefabricated ...

OBJECTIVES To assess the fracture resistance of endodontically treated teeth with a novel Zirconia (Zr) nano-particle filler containing bulk fill resin composite. METHODS Forty-five freshly extracted maxillary central incisors were endodontically treated using conventional step back preparation and warm lateral condensation filling. Post space preparation was performed using drills compatible...

BACKGROUND Post-retained crowns are indicated for endodontically treated teeth (ETT) with severely damaged coronal tissue. Metallic custom and prefabricated posts have been used over the years, however, due to unacceptable color, extreme rigidity and corrosion, fiber posts, which are flexible, aesthetically pleasing and have modulus of elasticity comparable with dentin were introduced. AIM To...

OBJECTIVES The objective of this study is to evaluate the frequency and distribution of early tooth loss and endodontic treatment needs of permanent first molars in a Turkish pediatric population. MATERIALS AND METHODS A total of 7,895 panoramic radiographs taken for routine dental examination at the Department of Oral Maxillofacial Radiology between 2008 and 2012 years were investigated. Two...

Procedure Following nonsurgical root canal treatment, a post space is created in the root canal by careful removal of the coronal canal obturating material. A sufficient amount of material must be retained in the apical portion of the canal to maintain an adequate apical seal. A custom or proprietary post is fitted and cemented into the root canal for core retention. The post should be passivel...
