This prospective study was undertaken to determine the incidence of post obturation pain related to root canal treatment of asymptomatic non-vital maxillary central incisor teeth that were prepared and filled in one visit using two different manual rootcanal preparation techniques: the step-back and the step-down and to determine the relationship, if any between post obturation pain and root ca...

BACKGROUND AND OBJECTIVE To date, many different materials have been proposed for root canal fillings, but gutta-percha (used with various types of sealers) has remained the material of choice for over a century. A new root canal obturation system, the Epiphany endodontic obturation system, has been developed to replace gutta-percha and traditional sealers for root canal obturation. The purpose...

AIM To compare the apical seal of lateral condensation technique, thermafil and one-step by using this model. MATERIALS AND METHODS A two-chamber bacterial microleakage model using E. faecalis as microbial marker was used for evaluation of the leakage. Bacterial penetration was monitored over a 60-day period. Leakage was recorded when turbidity was observed in the lower chamber. RESULTS Aft...

Capík I., S. Štvrtina: Comparison of Gutta-Percha Obturation Techniques in the Treatment of Wide Root Canals in Dogs. Acta Vet. Brno 2008, 77: 291-296. An in vitro study was conducted to compare gutta-percha obturation techniques of the developing incisors in dogs. Two perpendicular radiographic views were used for evaluation of apical and overall appearance of root canal obturation. Apical lea...

Pulpal and periradicular diseases are primarily caused by bacterial invasion of the root canal system as a result of caries progression. The presence of residual bacteria at the time of root canal completion (obturation) is associated with significantly higher rate of treatment failure. Re-infection of obturated root canals can be potentially prevented by enhancing the antibacterial activities ...

NTRODUCTION The goals of root canal therapy are to remove infected and necrotic pulpal tissue remnants, shape the root canal system to facilitate irrigation and medication and adequate sealing using obturation materials. 1 Rotary instruments enhance the quality of obturation by providing conical shape to the root canal. Nickle titanium (NiTi) alloy instruments inherent flexibility that allows t...

Background: It is difficult to identify a potential sealant with penetration depth until practically analyzed. A scanning electron microscopy (SEM) overview could better describe the internal picture of the materials sealed to the tooth surface on in vitro experimentation since it being a vital procedure for successful obturation. Hence, this study was undertaken to compare the penetration dept...

INTRODUCTION The production of smear layer during canal instrumentation is thought to increase coronal microleakage even after canal obturation. Previous studies have shown that the type of irrigant does not necessarily affect the seal of the obturation. Our study aimed to evaluate the effect of three irrigation solutions (MTAD, citric acid and EDTA/NaOCl) on the coronal microleakage of root ca...

BACKGROUND It has been observed that the general dentists and pedodontists differ in their treatment recommendations for pulp therapy in deciduous teeth. AIM To determine the knowledge and practice of pulp therapy in deciduous teeth by general dental practitioners (GDP) in two cities of southern Saudi Arabia. SUBJECTS AND METHODS Fifty GDP selected at random from government and private dent...

A prospective in vivo investigation was conducted to determine radiographic and clinical factors associated with contemporary nonsurgical endodontic retreatments. Approximately 1,100 failing endodontically treated teeth were screened to determine an appropriate treatment plan. Using magnification, 337 consecutive retreatment cases were evaluated and treated. The vast majority of the retreated c...
