The aim of this study was the evaluation of the long term results in the clinical applicability of two root canal sealers, Sealapex Xpress Kerr Endodontics (non-eugenol, calcium hydroxide polymeric root canal sealant) and AH Plus Jet Dentsply Maillefer (epoxy resin-based sealant). 225 teeth of 159 patients included in this study, were endodontic treated and filled with the previously mentioned ...

OBJECTIVE This study evaluated whether smear layer removal has any influence on the filling of the root canal system, by examining the obturation of lateral canals, secondary canals and apical deltas. MATERIAL AND METHODS Eighty maxillary and mandibular canines were randomly divided into two groups, according to their irrigation regimen. Both groups were irrigated with 1% NaOCl during canal s...

Introduction: Statement of the Problem: Cleaning and shaping are regarded as the most important aspects of root canal therapy and prerequisite for the success of endodontic treatment. Apical transportations can jeopardize the outcome of treatment due to the significant decrease in the sealing ability of root filling material. The purpose of this study was to evaluate transportation in type II c...

UNLABELLED During mechanical preparation of the post space, the root canal filling may be twisted or vibrated, depending on several factors associated with the preparation technique and quality of filling. OBJECTIVE The purpose of this study was to investigate the effect of immediate and delayed post space preparation on the integrity of the apical seal. MATERIAL AND METHODS Sixty-four extr...

The purpose of this study was to investigate the periapical healing process of dogs' teeth with or without apical patency and after root canal filling with two types of sealers. Forty roots of premolars and incisors were utilized. The root canals were over-instrumented and dressed with a corticosteroid-antibiotic solution for 7 days to obtain ingrowth of periapical connective tissue into the ca...

This study evaluated the removal of filling material with ProTaper Universal Rotary Retreatment system (PTR) combined with solvents and the influence of solvents on the bond strength (PBS) of sealer to intraradicular dentin after canal reobturation. Roots were endodontically treated and distributed to five groups (n = 12). The control group was not retreated. In the four experimental groups, ca...

introduction: the aim of this in vitro study was to compare the efficacy of protaper retreatment (protaper r) and mtwo retreatment (mtwo r) files in removing gutta-percha and guttaflow from endodontically treated straight root canals. methods and materials: the root canals of 60 human mandibular single-rooted premolars were prepared and randomly divided into two groups ( n =30). in groups a and...

Contemporary research points to infection control as the key determinant of endodontic success. While epidemiological surveys indicate that success is most likely in teeth which have been densely root-filled to within 2 mm of root-end, it is unclear whether the root canal filling itself is a key determinant of outcome. It is also unclear how different materials and methods employed in achieving...

UNLABELLED The development and maintenance of the sealing of the root canal system is the key to the success of root canal treatment. The resin-based adhesive material has the potential to reduce the microleakage of the root canal because of its adhesive properties and penetration into dentinal walls. Moreover, the irrigation protocols may have an influence on the adhesiveness of resin-based se...
