UNLABELLED The radicular groove is a developmental anomaly that predisposes the tooth to periodontal break-down. Sometimes the situation becomes more complicated by pulp necrosis and development of a combined endodontic-periodontal lesion which is a diagnostic and treatment challenge for the clinician. This report presents the successful management of an endodontic-periodontal lesion in a maxil...

Background: B-cell activating factor belonging to the TNF family (BAFF) levels may increase in response to oral infections. The aim of the study was to evaluate saliva and serum BAFF levels in patients with oral infection and to monitor them after dental treatments. Materials and methods: Fifteen patients with an oral infection foci including pericoronitis (n = 7) and irreversible pulpitis (n =...

OBJECTIVE This study sought to investigate the prevalence of eight oral Treponemas (Treponema denticola, T. amylovorum, T. maltophilum, T. medium, T. pectinovorum, T. socranskii, T. vicentii and T. lecithinolyticum) in teeth with endodontic treatment failure and periapical lesion. METHODS Samples were taken from 40 root canals presenting endodontic failure and periapical lesion. DNA extractio...

A case of orofacial pain and inferior alveolar nerve (IAN) paraesthesia after extrusion of endodontic sealer within the mandibular canal treated with prednisone and pregabalin is described. A 36-year-old woman underwent root canal treatment of the mandibular second right premolar tooth. Post-operative panoramic radiograph revealed the presence of radiopaque canal sealer in the mandibular canal....

The purpose of this article is to identify the incidence of complications and the most common complications associated with single crowns, fixed partial dentures, all-ceramic crowns, resin-bonded prostheses, and posts and cores. A Medline and an extensive hand search were performed on English-language publications covering the last 50 years. The searches focused on publications that contained c...

BACKGROUND Finite element simulation has been used in last years for analysing the biomechanical performance of post-core restorations in endodontics, but results of these simulations have been interpreted in most of the works using von Mises stress criterion. However, the validity of this failure criterion for brittle materials, which are present in these restorations, is questionable. The obj...

INTRODUCTION Clinicians are regularly confronted with difficult choices. Should a tooth that has not healed through nonsurgical root canal treatment be treated through endodontic microsurgery or be replaced using a single implant? Acquiring complete, unbiased information to help clinicians and their patients make these choices requires a systematic review of the literature on treatment outcomes...

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 ...

an important factor that interferes with the bonding between the root canal wall and resin cement is the root canal sealer remnant. there is controversy about the effect of eugenol-containing sealers on the bond strength between resin cements and fiber post. the aim of this study was to evaluate the effect of the type of endodontic sealer on the bond strength of frc posts cemented with resin ce...

AIMS The aim of the present study is to compare and assess the fracture resistance of root canal treated teeth with different restorative materials. MATERIALS AND METHODS The present in vitro study was carried out on seventy-five freshly extracted, noncarious, single-canal human lower-first premolars with similar anatomic characteristics. Teeth were randomly assigned to five groups with 15 te...
