Sealer placement techniques have not been examined in teeth with curved canals prepared with Lightspeed instruments. Three traditional methods of placing sealer were studied, using 45 extracted human single-rooted teeth, divided into 3 groups of 15. Root canal preparations were made with Light-speed nickel-titanium, engine-driven instruments. AH26 sealer was applied with either K-file, lentulo ...

Root canal filling materials, including sealercement and obturation points or cones, are used in root canal treatment to occlude the apical portion of the canal. These will block the dentinal tubules preventing passage of tissue fluids, toxins, and microorganisms into the root canal space. Many investigators have demonstrated the importance of a sealer cement for effective root canal obturation...

large number of clinical cases in endodontics, however, cytotoxicity of such sealers must be tested before their validation as fi lling materials. the aim of this study was to evaluate the cytotoxic effect of a new copaiba oil-based root canal sealer (biosealer [bs]) on osteoblast-like osteo-1 cells. materials and methods: the experimental groups were formed according to the culture medium cond...

tooth discoloration induced by endodontic sealers, is a common finding that impairs aesthetic outcome of endodontic treatment. the aim of the present mini literature review, was to summarize the existing data on discoloration potential of different endodontic sealers. the research covered the article published in pubmed and google scholar from 2000 to 2015. the searched keywords included ‘tooth...

BACKGROUND The aim of this study was to evaluate the bond strength of AH plus, Acroseal, and Adseal to the root canal dentin. METHODS A total of 36 single-rooted, mandibular premolar teeth were used. Root canal shaping procedures were performed with ProTaper rotary instruments (Dentsply Maillefer) up to size F4. The prepared samples were then randomly assembled into 3 groups (n = 12). For eac...

The purpose of this retrospective study was to evaluate the treatment outcome of root canal systems obturated with gutta-percha and Kerr Pulp Canal Sealer compared with Resilon and Epiphany sealer. One hundred three teeth treated in a private endodontic practice were included in the study. Clinical outcomes (healed versus nonhealed) were assessed by using the Periapical Index determination and ...

introduction: the purpose of this ex vivo study was to determine the releasing characteristics and doxycycline dentinal diffusion of ah26 sealer-doxycycline combination from apical 3mm of tooth root and apical foramen . materials & methods: one-hundred and two recently extracted single-rooted human teeth were decoronated and prepared with #3 and #4 gates-glidden drills and rotary mtwo files. sm...

Microbes are considered as the primary etiologic agents in endodontic diseases. The ways of reducing these agents are: root canal debridement, antimicrobial irrigants and antibacterial filling materials. But the complexity of the pulp canal system presents a problem for chemo mechanical preparation. One of the factors determining the success of endodontic treatment is the sealing material with ...

The purpose of this in vitro study was to evaluate two commonly used gutta-percha solvents for their effectiveness in dissolving several types of root canal sealers. Seven different sealers (AH26, AH Plus, Diaket, Roekoseal, Sankin Apatite Root Sealer, Sealapex, and Sultan U/P) were used in this study. After mixing according to the manufacturers' directions, each material was syringed into 30 g...
