AIM The aim of this study was to evaluate by means of radiographs the technical quality of root fillings performed by dental practitioners. METHODS AND MATERIAL Standardized periapical radiographs were made on 484 patients who received endodontic treatment in private practice. A total of 831 endodontically treated teeth with 1448 roots were evaluated for technical quality of the root canal fi...
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...
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'...
Restoration of endodontically treated teeth is a common problem in dentistry, related to the fractures occurring in such teeth and to concentration of forces little information regarding variation of basic preparation guidelines in stress distribution has been available. To date, there is still no agreement in the literature about which material or technique can optimally restore endodontically...
OBJECTIVES This retrospective study investigated the clinical effectiveness over up to 8 years of parallel-sided and of tapered glass-fiber posts, in combination with either hybrid composite or dual-cure composite resin core material, in endodontically treated, maxillary anterior teeth covered with full-ceramic crowns. METHODS The study population comprised 192 patients and 526 endodontically...
The purpose of this study was to analyze four different cone-beam computed tomography (CBCT) protocols to identify horizontal root fractures (HRF) in endodontically treated teeth, with or without the presence of a metallic post. Thirty extracted single-rooted human premolars were treated endodontically. Afterwards, an observer induced a horizontal fracture in 15 teeth. Each tooth was inserted i...

t s m r a o reservation of teeth has been the treatment of hoice and a fundamental principle of dentistry. In ontrast, the extraction of natural teeth has been onsidered undesirable because of the often limited ong-term success of the alternate prosthodontic relacements. To this end, heroic efforts have been ade to preserve teeth, ranging from advanced enddontic and periodontal therapy (includi...
BACKGROUND Studies have been carried out on endodontically treated teeth restored with and without ferrule, and influence of the cementing medium, to evaluate their effect on fracture resistance. This study was conducted on 28 freshly extracted maxillary central incisors. Specimens were restored with two types of post designs, and cemented with two different luting agents, and tested for fractu...
The aim of this study was to assess the prevalence and risk factors of apical periodontitis in endodontically treated teeth in a selected population of Brazilian adults. A total of 1,372 periapical radiographs of endodontically treated teeth were analyzed based on the quality of root filling, status of coronal restoration and presence of posts associated with apical periodontitis (AP). Data wer...
