BACKGROUND A prospective study was started in 1995 to evaluate the success of carbon fibre reinforced epoxy resin (CFRR) posts used to restore endodontically treated teeth. All the teeth in the study had lost more than 50% of their coronal structure. METHODS Fifty-nine carbon fibre Composiposts cemented with Metabond and built up with Core Paste cores were placed into the teeth of 47 patients...

STATEMENT OF PROBLEM An extensive review of the published literature has revealed a wide divergence of opinion regarding the suitability of different post systems for endodontically treated teeth. As a result, the dentist has no clear guidelines concerning the selection of suitable post systems that will provide adequate retention while minimizing subsequent root fracture. PURPOSE This study ...

AIM The aim of this study was to investigate the quality of endodontic and coronal restorations and the association with periapical status in a Danish population. METHODOLOGY A total of 614 randomly selected individuals (20-60+ years of age) from Aarhus County had a full-mouth radiographic examination. The quality of endodontic and coronal restorations and the periapical status of endodontica...

introduction: in cases of severe hard tissue loss, 2 mm circumferential ferrule is difficult to achieve. so in these cases we should use different ferrule designs. this in vitro study investigated the effect of different ferrule designs on the fracture resistance of teeth restored with bonded post and cores. materials and methods: forty freshly-extracted central incisors were endodontically tre...

The purpose of this study was to evaluate the histologic response after replantation of mature, developed teeth without endodontic treatment in monkeys. To serve as experimental controls, the other replanted teeth received endodontic treatment. No significant differences were noted in the rate and quality of periodontal tissues healing between the endodonticall and the nonendodontically treafed...

Although the published papers about this matter is limited to clinical case reports, the aim of this review was to quantify the success rate of immediate vs late orthodontic extrusion of traumatically intruded teeth. From 55 reports in a PubMed and Medline computerized search, 13 reported patients involving 22 traumatically intruded anterior upper teeth with orthodontic extrusion were selected....

objective: vertical root fracture (vrf) is among the most common causes of endodontic treatment failures. this study aims to compare charge-coupled devices (ccd) and photostimulable phosphor plates (psp) for detection of vertical root fractures in endodontically treated teeth.   methods: in this diagnostic in vitro study, 40 maxillary anterior teeth were selected and after preparation and root ...

External apical root resorption (EARR) is a frequent iatrogenic problem following orthodontic treatment in endodontically-treated teeth, about which the literature reports substantial variability in post-orthodontic treatment EARR responses. The main focus of the present study is to clarify whether variants in the interleukin-1 receptor antagonist gene coding for the IL-1ra protein have a posit...

OBJECTIVES This study compared the fracture strength and survival rate of endodontically treated crowned maxillary incisors with approximal class III cavities and different core build-ups. METHODS Sixty-four caries free human maxillary central incisors were selected for standardized size and quality, endodontically treated and prepared with approximal cavities 3mm in diameter. Group 1 was res...

INTRODUCTION The purpose of this prospective study was to analyze the factors related to extraction of endodontically treated teeth. METHODS One hundred nineteen cases of extraction of endodontically treated teeth were consecutively reviewed, and the following items were recorded: type of tooth; presence and type of coronal restoration; motive of consultation; reasons for extraction; patient'...
