The case reports describes non surgical healing in periradicular lesions.A conservative approach with 5.25% sodium hypochlorite was used for irrigation, and calcium hydroxide was used for the intra-canal dressing and 2% chlorohexidine as a final irrigant. Periapical healing was observed 1 month after obturation and continued in the 12-month recall. This report confirms that the large size of a ...

The successful outcome of root canal therapy is related to the ability to negotiate the canal to its apical terminus, allowing thorough debridement, disinfection, and obturation of the prepared canal space. In situations in which calcific deposits have blocked access to the canal, treatment efforts are often thwarted. This article describes endodontic management of tooth with calcific metamorph...

OBJECTIVE To analyse the influence of root canal instrumentation and obturation techniques on intra-operative pain experienced by patients during endodontic therapy. METHOD AND MATERIALS A descriptive cross-sectional study was carried out in Ponferrada and Sevilla, Spain, including 80 patients (46 men and 34 women), with ages ranged from 10 to 74 years, randomly recruited. Patient gender and ...

PURPOSE To evaluate the use of Portland cements with additives as furcation perforation repair materials and assess their biocompatibility. METHODS The four maxillary and mandibular premolars of ten male mongrel dogs (1-1.5 years old, weighing 10-15 kg) received endodontic treatment (n=80 teeth). The furcations were perforated with a round diamond bur (1016 HL). The perforations involved the ...

The aim of this study was to evaluate the influence of two different irrigation protocols on artificial lateral root canal filling capacity using different obturation techniques. Sixty single-root human teeth were used. Two artificial lateral canals were created in the apical third. Root canals were instrumented up to a 45 K-file to the working length. Before each file, root canals were irrigat...

STATEMENT OF PROBLEM Studies reported that nearly 60% of endodontic failures have been attributed to inadequate obturation of the root canal system. Thus, complete obturation of the root canal system and proper apical seal are essential elements in the long-term success of root canal treatment. PURPOSE This study aimed to compare the apical seal of lateral condensation technique in the room a...

Background : Dental caries occurs as a result of demineralization the hard tissues teeth followed by destruction organic matter, resulting in bacterial invasion and death pulp which can lead to necrosis. One treatments for necrosis is endodontic treatment. Endodontic treatment includes root canal preparation techniques, irrigation materials, dressing also obturation techniques. In experience fl...

The design and implementation of shaping, cleaning and sealing objectives in root canal therapy are fraught with real and potential pitfalls when the anatomic complexity of the space and technical considerations for its instrumentation, disinfection and obturation are contemplated. This review will focus on the genesis of results that lead to endodontic overfills. We will look at how the litera...

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...

AIM This systematic review was undertaken in order to develop guidelines for the European Academy of Paediatric Dentistry for the management of non-vital permanent anterior teeth with incomplete root development. METHODS Three techniques were considered; apexification by single or multiple applications of calcium hydroxide, use of Mineral Trioxide Aggregate (MTA) for the creation of an apical...
