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 ...
OBJECTIVE The aim of this study was to compare the fracture resistance of roots obturated with different materials. STUDY DESIGN Sixty root canals were instrumented and divided into 4 equal groups (n = 15 each). The root canals in group 1 were filled with AH26 sealer and gutta-percha, in group 2 with Resilon and Epiphany, and in group 3 with Ketac-Endo Aplicap and gutta-percha. Fifteen root c...
The objective of this study was to compare the sealing ability of ActiV GP/glass ionomer (GI) sealer (Brasseler USA, Savannah, GA), Resilon/Epiphany (Pentron Clinical Technologies, Wallingford, CT), and gutta-percha (GP)/AH Plus (Dentsply Maillefer, Tulsa, OK). Seventy-three human single-rooted teeth were randomly divided into three test groups (20 canals each) and two control groups (5 positiv...
Strengthening of Resilon-filled roots via an adhesive interface should be reflected by improvement in the interfacial strength and dislocation resistance between the root fillings and intraradicular dentin. This study compared the interfacial strengths of Resilon/Epiphany and gutta-percha/AH Plus using a thin-slice push-out test design. Failure modes of root slices after push-out testing were e...
Epigenetics refers to changes in a biological phenotype that are not due to an underlying change in genotype. In eukaryotes, epigenetics involves a set of chemical modifications of the DNA and the histone proteins in nucleosomes. These dynamic changes are carried out by enzymes and modulate protein-protein and protein-nucleic acid interactions to determine whether specific genes are expressed o...
In the infinite mass limit for a heavy quark its spin decouples from the QCD dynamics, which leads to the heavy-quark spin symmetry. After a short discussion of spin symmetry some applications are considered. Contribution to the Crakow Epiphany Conference on Spin Effects in Particle Physics January 9–11, 1998, Crakow, Poland.
introduction: vertical root fracture inevitably leads to tooth extraction. thus, root filling with obturating materials and sealers that can reinforce the tooth would be an ideal way to reduce fracture in root treated teeth. this study aimed to assess the fracture resistance of roots following the application of different sealers including epiphany, iroot sealer and ah-plus. methods and materia...
Background: The objective of three-dimensional obturation is to completely seal the canal system from any bacterial ingress from the oral cavity and periradicular tissues. The aim of the study to compare the push-out bond strength of the smart seal C-point obturating system with epiphany resilon obturation system and the gold standard gutta-percha/AH plus system. Materials and Methods: Thirty e...
