Purpose: This in vitro study aimed to evaluate the influence of fatigue loading on fracture resistance endodontically treated molars restored with endocrowns using different machinable blocks. Methods: Endodontically mandibular first were prepared a standardized method. Specimens divided into 4 groups (n = 10).Anatomically shaped manufactured VITA ENAMIC (VE) and KATANA Zirconia (KZ). Layered I...

occlusal rest (Fig. 5, B), and guiding planes (Fig. 5, C). If there are voids or irregularities, they are filled with monomer and powder with a paint brush. 9. Try-in the removable partial denture (Fig. 6) to ensure a proper adaptation of the resin coping (Fig. 7). The die spacer can be removed from the tooth with a cotton pellet soaked in die spacer thinner. Rinse the tooth several times befor...

The restoration of endodontically treated teeth is one of the most challenging situations of the dentist s̀ clinical practice, because it involves procedures related to several areas, such as Endodontics, Operative Dentistry, and Prosthetics. These restorations aim to replace the structures lost during endodontic surgery and access to both the pulp chamber and root canal system during the instru...

the root canal treatment (RCT) prognosis. The successful RCT prevents tooth loss and avoids pain and apical periodontitis. This review aimed to categorize common operative procedure errors and clinical factors associated with RCT. Based on this, will be approached common errors of procedures within the clinical operative sequence: endodontic treatment planning, pulp and periapical disease diagn...

This study compared the difference in decision making regarding retreatment of endodontically treated teeth by general dental practitioners and endodontists. Thirty radiographs of endodontically treated teeth taken from undergraduate records with their respective case descriptions were submitted to fifteen endodontists and fifteen general dental practitioners. Seven treatment alternatives were ...

endodontically treated teeth (ETT) in a general practice environment related to periodontal parameters. Data from 360 restored ETT treated between 2000 and 2011 were collected. Dates of interventions like restorations, repairs, replacements and extractions were recorded. Additionally, general information about patients and dentitions as well as periodontal status was recorded. Success was analy...

Restoration of endodontically treated teeth becomes especially complex when the involved teeth have previously undergone trauma, treatment for caries, fractures, endodontic-access preparation, canal instrumentation and other idiopathic causes. Excessive loss of dental hard tissues and inadequate maxillomandibular relationship possess difficulties for the esthetic result of subsequent prosthetic...

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 systematic review aims to summarize the current clinical studies that investigated survival rates against fracture of endodontically treated posterior teeth restored with crowns or resin composite restorations. Literature search were performed using keywords. Publications from 1980 to 2016 were searched in PubMed, ScienceDirect, Web of Science, MEDLINE, and SCOPUS. Included studies were se...

To determine whether the distance between the post and the residual gutta-percha influences the clinical outcome of endodontic treatment, 94 endodontically treated teeth following post and core restoration were evaluated radiographically. The teeth were divided into three groups: (I) no gap between the gutta-percha and the post; (II) a gap of >0 to 2 mm; (III) a gap of >2 mm. Treatment outcome ...
