Decontamination of Gutta-percha Cones with Different Chemical Agents
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...
متن کاملSubcutaneous Reaction of Rat Tissues to Nanosilver Coated Gutta-Percha
INTRODUCTION Gutta-percha (GP), is a neutral and non-toxic material. The aim of this animal study was to compare the biocompatibility of nanosilver coated GP (NS-GP) with conventional GP in subcutaneous tissues in a rat model. METHODS AND MATERIALS Conventional GP and NS-GP were subcutaneously implanted in the backs of 20 male Wistar rats (n=10). A control animal was assigned for each trial p...
متن کاملComponent Analysis of Four Commercial Brands of Gutta-Percha
INTRODUCTION Gutta-Percha, the concrete milky juice of the Sapotaceae family tree, is the most commonly used material for obturation of prepared canal space. Natural 1-4 trans stereochemical structure of Gutta-Percha is taken to a heating- inclusion process of various organic and inorganic elements by manufacturers. The purpose of this study is to detect the presence and percentage of inorganic...
متن کاملEvaluation of the Thermoplasticity of Different Gutta-percha Cones and the Tc System
OBJECTIVE The aim of this study was to evaluate the thermoplasticity of three commercial brands of gutta-percha (Tanari, Dentsply 0.06, and Roeko), and of the TC system. MATERIALS AND METHODS Standardized specimens were fabricated from the materials to be evaluated. Specimens were placed in water at 70 degrees C for 60 seconds. Following that, they were positioned between two glass slabs and ...
متن کاملEffect of Different Tapered Gutta Percha Cones in Apical Microleakage of Human Root Canal Obturation
Background and purpose: Gutta-percha is generally accepted as the main canal filler. Standard gutta-percha cones are available in 2-10% tapers. The purpose of this study was to compare apical microleakage of canals obturated with different tapers of gutta-percha, using the protein penetration technique. Materials and methods: In this study, 96 maxillary anterior teeth were selected and were pr...
متن کاملEvaluation of the thermoplasticity of different gutta-percha cones and Resilon.
The goal of this study was to evaluate the thermoplasticity of conventional and thermoplastic gutta-percha and Resilon, a polyester polymer-based material. Specimens with standardised dimensions were made from the following materials: conventional and thermoplastic gutta-percha (Dentsply), conventional and thermoplastic gutta-percha (Endopoints) and Resilon. After 24 h, the specimens were place...
