INTRODUCTION General dental practitioners provide the majority of treatment in Iran. The aim of this study was to gather information on the methods, materials and attitudes employed in root canal treatment by dentists participated in 7(th) Congress of Iranian Academy of Restorative Dentistry in Shiraz /2007 in order to evaluate the quality of current practice. MATERIALS AND METHODS A question...

OBJECTIVES To investigate and compare postoperative pain after one-visit root canal treatment (RCT) on teeth with vital pulps using three different obturation techniques. STUDY DESIGN Two hundred and four patients (105 men and 99 women) aged 12 to 77 years were randomly assigned into three treatments groups: cold lateral compaction of gutta-percha (LC), Thermafil technique (TT), and Backfill ...

AIM To gather data from Diplomates of the American Board of Endodontics regarding treatment of dilacerated canals. MATERIALS AND METHODS A questionnaire addressing definition, endodontic treatment procedures and prognosis was constructed and distributed via e-mail to 708 Diplomates of the American Board of Endodontics. Data from 150 respondents, a 21% response rate, were collected by using a ...

Introduction: Internal root resorption is a progressive loss of dentin in teeth with inflamed and possibly partially necrotic pulp tissue. If diagnosed at early stages, the process is halted by endodontic treatment. While endodontic treatment is the preferred treatment modality for internal root resorption, current standard endodontic techniques pose a challenge for cleaning, disinfection and o...

Reaction of the airways to inhaled Berodual was evaluated in two groups of metallurgists surveilled by systematic, complex medical examinations for appx. 25 years: 31 coke oven and 31 cold-rolling mill workers. All subjects under examination were active smokers, smoking more than 20 cigarettes a day. The frequency of ventilatory disorders (central bronchi obturation, small bronchi obturation, a...

The aim of this study was to compare the vertical fracture resistance of roots obturated with different root canal filling materials and sealers. Crowns of 55 extracted mandibular premolar teeth were removed to provide root lengths of 13 mm. Five roots were saved as negative control group (canals unprepared and unfilled). Fifty root canals were instrumented and then five roots were saved as pos...

Understanding the morphology of the root canal plays a key role in the success of a root canal therapy. Thus considerations of the anatomic variations, in the process of diagnosis and treatment of the maxillary and mandibular posterior teeth, should be done by the clinicians.1 A thorough examination of pre-operative and postoperative radiagraphs plays a critical role in endodontic success. Vari...

The rehabilitation of a maxillectomy patient involves meticulous treatment planning and designing. Lack of retention and facial support and limited mouth opening are the major issues that lead to functional and psychological trauma in post-maxillectomy patients. The successful rehabilitation of a maxillary defect includes restoring the function, esthetics, and a complete obturation of the defec...

The objectives of endodontics are the prevention and cure periapical disease (Apical Periodontitis); which is achieved by cleaning disinfection root canal system subsequent obturation spaces filling with inert materials, avoiding reinfection persistent inflammation [1].

The aim of this study was to evaluate the in vitro obturation quality of four filling methods: active lateral condensation, a modification of Tagger's hybrid technique, ENAC ultrasound technique and the Microseal technique. The study was performed on one hundred and sixteen single-rooted human teeth, divided into four groups of twenty nine teeth, embedded in resin, longitudinally sectioned and ...
