Background and Aim: Tooth discoloration induced by endodontic sealers is an un-desired outcome of endodontic treatment that affects the esthetic appearance of the teeth, which is important especially in the anterior region. The aim of the present study was to compare the coronal discoloration caused by two frequently used resin-based sealers namely EasySeal and AdSeal. Materials and Methods: F...

AIM The hypotheses tested in this study were that: (i) Enterococcus faecalis can survive long-term entombment in root filled teeth without additional nutrients, (ii) initial cell density influences the survival of E. faecalis in instrumented root canals and (iii) gelatinase-production capacity influences the survival of E. faecalis in root canals. METHODOLOGY The root canals of 150 extracted ...

The purpose of this in vitro study was to investigate the effects of the use of calcium hydroxide as an intracanal dressing on the sealing ability of a thermoplastic synthetic polymer-based root filling (Resilon). Forty-seven single rooted teeth were decoronated and instrumented to ISO sizes 40. The teeth were randomly divided into three experimental groups of 15 roots each. Group 1 was immedia...

introduction: the purpose of this study was to investigate root surface ph changes over a period of 4 weeks following treatment with calcium-hydroxide dressing of intact and resorbed roots. materials & methods: the canals of 30 single-rooted teeth were instrumented with protaper rotary files and randomly divided into 2 experimental groups of 14 each, and one control group with two samples. to s...

Introduction: Although composite resins have improved greatly since their introduction, microleakage is one of the most frequently encountered problems. This study compared the effects of different monomer systems and layering techniques on the bacterial leakage of Cl I composite resin restorations. Methods: Eighty-two sound human third molars were used. The teeth were randomly divided into six...

DOI: 10.5581/1516-8484.20130112 According to the Brazilian Ministry of Health the cross-sectional studies are important in health policy as the improvement of information systems allowing a diagnosis of the health situation of the population with epidemiological information obtained from primary data(1). Regarding oral health, the diagnosis of dental caries and periodontal disease should be est...

INTRODUCTION The present study compared the ability of the endodontic sealers AH Plus, Pulp Canal Sealer and EndoREZ to fill the root canal system in association with gutta-percha. METHODS Ninety mandibular premolars were accessed, prepared and divided into three groups of 30 teeth each, according to the sealer used to fill the canals: AH Plus, Pulp Canal Sealer and EndoREZ. All the teeth wer...

The presence of a missed canal in the course of root canal treatment is one of the common reasons for failure of therapy. The consequence of a missed canal will or may lead to chronic infection and post operative flare ups. Hence, it is very important to explore the morphology of the tooth as well its internal anatomy to overcome failure in endodontic practice. Root canal therapy of maxillary t...

OBJECTIVE This study aimed to assess the quality of root fillings, coronal restorations, complications of all root-filled teeth and their association with apical periodontitis (AP) detected by cone-beam computed tomography (CBCT) images from an adult Turkish subpopulation. MATERIAL AND METHODS The sample for this study consisted of 242 patients (aging from 15 to 72 years) with 522 endodontica...
