The purpose of this study was to evaluate the effectiveness of various chemical disinfectants in decontamination of gutta-percha (GP) cones contaminated with Bacillus subtilis spores. Sodium hypochlorite solution (4%), glutaraldehyde solution (2%), povidone-iodine solution (5%), and savlon solutions were compared for effectiveness in sterilizing gutta-percha cones contaminated with Bacillus sub...

An investigation of the most popular retrograde technique for their marginal adaptation to dentin was attempted. Forty extracted maxillary central incisors were instrumented and obturated, and various apical procedures were performed. The scanning electron microscope was used to record the results. Retrograde amalgam, heat-sealed gutta-percha, and the apicoectomy control showed average marginal...

This research has the purpose to determine characteristics of synthesis 20 ppm nanogold using TEM, effect adding on antioxidant activity Moringa leaves, and best concentration that supports increasing in leaves. Nanogold nanosilver were synthesized bottom-up methods. The concentrations used for leaf extract 5, 10, 15, 20, 25, 30 ppm. is Nanosilver at a had inhibition antibacterial activity. Tes...

The nanosilver food packaging films were developed by polyvinyl alcohol activated with Satureja rechingeri extract (S-AgNPs/PVA) using the solvent casting to evaluate freshness of Oncorhynchus mykiss fillets during 14 days at refrigerated temperature. 160 pieces fish enfolded in 4 types as main group-series. components carvacrol (83.2%) p-cymene (3.11%), thymol (2.13%) and γ-terpinene (1.63%). ...

OBJECTIVES The aim of this study was to evaluate the effect of gutta percha/AH26 and Resilon/RealSeal SE on residual antimicrobial activity of chlorhexidine (CHX) in human root dentin and suggest the best filling material when CHX is used as final irrigant. MATERIALS AND METHODS One-hundred and forty-four single-rooted human teeth were selected for this study. Canals were instrumented to the ...

The purpose of this study was to evaluate the potential of using mineral trioxide aggregate as a root canal filling material by comparing its apical sealing ability with that of laterally condensed gutta-percha with sealer and high-temperature thermoplasticized gutta-percha with sealer in extracted bovine teeth. Sixty bovine incisors with single canals were prepared in a standard manner using L...

PURPOSE The aim of this study was to investigate the accuracy of cone-beam computed tomography (CBCT) in the diagnosis of vertical root fractures in a tooth with gutta-percha and prefabricated posts. MATERIALS AND METHODS This study selected 96 extracted molar and premolar teeth of the mandible. These teeth were divided into six groups as follows: Groups A, B, and C consisted of teeth with ve...

Introduction: Lateral condensation effectiveness may be influenced by the gutta-percha and finger spreader taper used during root canal obturation. Objective: To evaluate the penetration ability of finger spreader into simulated root canals prepared using MTwo rotary system and filled with different gutta-percha and finger spreader tapers. Material and methods: Resin blocks with curved root can...

BACKGROUND The key to success of any root canal therapy is adequate obturation of the prepared root canal space. Root canal sealers are not dimensionally stable and might dissolve partially over a period of time. The objective of this in vitro study is to evaluate the push-out bond strength to intraradicular dentin of two endodontic obturation materials. MATERIAL AND METHODS Forty extracted s...
