Effects Of Various Hemostatic Agents On Bone, David Daryl Roland Sep 2003

Effects Of Various Hemostatic Agents On Bone, David Daryl Roland

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies have evaluated the effects of various hemostatic agents on radicular tissues following apical surgery. The purpose of this study was to examine the early osseous responses to seven hemostatic agents under identical conditions in rabbits. Sixteen adult male New Zealand white rabbits were used for this study. Following anesthesia, utilizing a midline submandibular incision, standardized bony defects were prepared on the lateral-superior regions of the mandible. Test materials were placed using standardized volumes and exposure times. Bone wax, Surgicel, Capset, alginate, Cut-Trol, Hemogin-L, and silver nitrate were compared to control sites irrigated with saline. Test materials or controls …


Effects Of Mtad On Some Physical Properties Of Enamel And Dentin, Tanya Kristina Machnick Jun 2003

Effects Of Mtad On Some Physical Properties Of Enamel And Dentin, Tanya Kristina Machnick

Loma Linda University Electronic Theses, Dissertations & Projects

Recently, a Mixture of Tetracycline, an Acid, and a Detergent (MTAD) has been advocated to remove smear layer and disinfect canals. The purpose of this study was to evaluate the effect of MTAD the flexural strength and modulus of elasticity of dentin as well as its effect on the bond strength to enamel and dentin. In Part I, dentin bars were randomly assigned to eight groups treated either with various concentrations of NaOCl (5.25%, 2.65%, 1.31%, 0.66%), 17% EDTA, MTAD, saline, or according to a clinical protocol with 1.3% NaOCl and then 5 min of MTAD. …


Effect Of Ca(Oh)2 On Survival Ability Of A Bacterial Mixture: An In Vitro Study, Nishan Antranik Odabashian Mar 2003

Effect Of Ca(Oh)2 On Survival Ability Of A Bacterial Mixture: An In Vitro Study, Nishan Antranik Odabashian

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this in vitro investigation was to evaluate the antibacterial effect of calcium hydroxide on a mixture of nine bacteria associated with endodontic infections at different time intervals and to examine the survival of the same bacteria when in mixture. A total of 102 teeth were used in the first part of the experiment. Eighty teeth were used in eight experimental groups of 10 each, 16 teeth were used for positive and negative controls, and six teeth were used for scanning electron microscopy (SEM). Nine species of bacteria were used in both experiments. These consisted of Enterococcus faecalis, …


The Effect Of Chlorhexidine Gluconate As An Endodontic Irrigant On The Apical Seal: Long-Term Results, David B. Ferguson Jan 2003

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 Jan 2003

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 …
