OBJECTIVE
Thermoplasticized techniques with high temperature and repetitive heating in root canal filling may cause degeneration of gutta-percha, producing cytotoxic byproducts and interfering sealing quality. This study was conducted to investigate the influence of cyclic heating on the physical
OBJECTIVE
The purpose of this study was to investigate the effects of 5.25% sodium hypochlorite (NaOCl) and 2% chlorhexidine (CHX) on Gutta-percha and Resilon cones using an atomic force microscope (AFM).
METHODS
Gutta-percha cones (n = 15) and Resilon cones (n = 15) were cut 3 mm from their tip,
OBJECTIVE
To compare the effects of 2% chlorhexidine (CHX) and 5.25% sodium hypochlorite (NaOCl) on gutta-percha (GP) cone structure using atomic force microscopy (AFM).
METHODS
Two standardized GP cones were sectioned 3 mm from the tip, attached to a glass base and immersed in 2% CHX or 5.25% NaOCl
UNASSIGNED
Sodium hypochlorite (5.25% NaOCl) and silver nanoparticles (70 ug/ml AgNPs) have a broad spectrum of antimicrobial efficacy for disinfecting gutta percha (GP) point, so this study was conducted to analyze the assay surface topography of GP when disinfected with AgNPs and 5.25% of NaOCl
The paresthesias of the inferior dental nerve consists of a complication that can occur after performing various dental procedures such as cystectomies, extraction of impacted teeth, apicoectomies, endodontic treatments, local anesthetic deposition, preprosthetic or implantologic surgery. The
The patent nasopalatine duct is a rare anomaly in the anterior maxilla. During the early fetal period, a bilateral and epithelium-lined duct is formed within the primary palatal process as an oro-nasal communication. However, the duct obliterates and degenerates before birth. A persisting patent or
The method of immediate root canal filling following vital pulp extirpation involves many problems to be solved clinically. Therefore, the present study was performed to increase the clinical usefulness by applying formalin medicine in the root canal before immediate root canal filling after vital
Adhesive strength of combination of several liner and filling materials used for filling dental root channels was studied and the marginal permeability of root channel from the side of the crown was evaluated after filling with several pairs of pad and filling materials. Filling of root channels
OBJECTIVE
To reduce the microleakage of a self-etching priming dentin adhesive with the use of antioxidant or bur finishing after sodium-hypochlorite or hydrogen-peroxide irrigation.
METHODS
70 single-root canals were enlarged and seven different treatment protocols were applied throughout the root
The aim of this study was to develop a new method of obturation by warm sealer in conjunction to single cone gutta-percha and evaluate the suitability of this technique to obturate complex root canal systems.Three root canal sealers namely, AH Plus, BioRoot The aim of this study was to evaluate the surface changes of nickel titanium (Ni-Ti) rotary retreatment files after three and five uses. Furthermore, the effects of 2% sodium hypochlorite and chloroform solutions and sterilization procedures on the NiTi rotary retreatment surfaces were investigated.
