Sealing Ability Promoted by Three Different Endodontic Sealers
INTRODUCTION The aim of this study was to evaluate the apical and coronal seal of endodontic filling promoted by the combined use of Sealer 26/gutta-percha, Endofill/gutta-percha and Resilon/ Epiphany. MATERIALS AND METHODS A total of 38 extracted human canine teeth were selected; 10 teeth for each test group and 4 for each control group. After conducting conventional endodontic treatment, th...
متن کاملRelease of formaldehyde by 4 endodontic sealers.
OBJECTIVE The purpose of this study was to evaluate the release of formaldehyde by some root canal filling materials. STUDY DESIGN Two older endodontic sealers, AH 26 and Endomethasone, and 2 recently available sealers, AH Plus and Top Seal, were analyzed. Infrared and electronic spectroscopy were used to determine formaldehyde content after set of the materials. RESULTS Analysis showed tha...
متن کاملCalcium Release and pH of Three Endodontic Root Canal Sealers
The aim of this study was to asses the calcium release and pH of three root canal sealers. pH and calcium release of three root canal sealers Apexit, Sealapex and Vitapex, were assessed at 30 and 60 min, and 7 days after spatulation. After manipulation, the sealers were placed in tubes and immersed in sealed glass flasks containing 10ml of deionized water and stored at 37°C. Tubes were removed ...
متن کاملComparison of Radiopacity of Six Endodontic Sealers
Introduction: Optimal radiopacity is one of the properties required for a root canal sealer that helps the distinction between the sealer and surrounding anatomic structures and evaluation of the quality of root filling. So, the purpose of this study was to evaluate the radiopacity of six root canal sealers at different focal distances. Materials and Methods: In this in vitro study, six endodo...
متن کاملGenotoxicity of three food processing contaminants in transgenic mice expressing human sulfotransferases 1A1 and 1A2 as assessed by the in vivo alkaline single cell gel electrophoresis assay
The food processing contaminants 2-amino-1-methyl-6-phenylimidazo[4,5-b]pyridine (PhIP), 5-hydroxymethylfurfural (HMF) and 2,5 dimethylfuran (DMF) are potentially both mutagenic and carcinogenic in vitro and/or in vivo, although data on DMF is lacking. The PHIP metabolite N-hydroxy-PhIP and HMF are bioactivated by sulfotransferases (SULTs). The substrate specificity and tissue distribution of S...
