K3 ENDO, PRO TAPER, AND PRO FILE SYSTEMS: BREAKAGE AND DISTORTION IN SEVERELY CURVED ROOTS OF MOLARS.By Matthew T. Ankrum, D.D.S.A Thesis submitted in partial fulfillment of the requirements for the degree of Master of Science at Virginia Commonwealth University.Virginia Commonwealth University, 2003Major Director: Gary R. Hartwell, D.D.S., M.S.Chairman and Professor, Department of EndodonticsIt was the aim of this study to investigate the incidence of file breakage and distortion when the Pro Taper, K3 Endo and ProFile systems were used to instrument canals in the severely curved roots of extracted molars.Forty-five roots of extracted mandibular and maxillary molars with curvatures …
The Effect Of Chlorhexidine Gluconate As An Endodontic Irrigant On The Apical Seal: Long-Term Results, David B. Ferguson
The Effect Of Chlorhexidine Gluconate As An Endodontic Irrigant On The Apical Seal: Long-Term Results, David B. Ferguson
Theses and Dissertations
The purpose of this study was to determine whether chlorhexidine gluconate (0.12%), used as an endodontic irrigating solution would affect the apical seal of three root canal cements. One hundred extracted human single-canal teeth were divided into 9 experimental groups of 10 teeth each, in addition to a positive and negative control group of 5 teeth each. The teeth were decoronated at the level of the cementoenamel junction, accessed, instrumented to a Master Apical File #50, irrigated with either sterile saline, 5.25% NaOCl or 0.12% chlorhexidine gluconate, and dried using paper points. Obturation was accomplished using lateral condensation and one …
The Effect Of Endodontic Solutions On Resorcinol-Formalin Paste In Teeth, Madelyn Gay Gambrel
The Effect Of Endodontic Solutions On Resorcinol-Formalin Paste In Teeth, Madelyn Gay Gambrel
Theses and Dissertations
This study determined if any of six endodontic solutions would have a softening effect on resorcinol-formalin paste in extracted teeth, and if there were any differences in the solvent action between these solutions. Forty-nine single-rooted extracted teeth were decoronated two mm coronal to the CEJ, and the roots sectioned apically to a standard length of 15 mm. Canals were prepared to a 12mm WL and a uniform size with a #7 Parapost drill. Teeth were then mounted in a cylinder ring with acrylic. The resorcinol-formalin mixture was placed into the canals and was allowed to set for 60 days in …
