The Effect Of Endodontic Solutions On Resorcinol-Formalin Paste, Ronald Nicholas Vranas

Theses and Dissertations

This study determined if any of four endodontic solutions would have a softening effect on resorcinol-formalin paste and if there were any differences in the solvent action between these solutions. Resorcinol, formalin and zinc oxide were mixed and allowed to set for 30 days. The solutions tested were 0.9% sodium chloride, 5.25% NaOCl, chloroform and Endosolv R. Seven samples per solution were tested and an additional seven samples served as controls. Each sample was saturated with one of the solutions and the depth of penetration was tested at 1 min, 2 min, 5 min, 10 min and 20 min using …

Placement Of Mineral Trioxide Aggregate Using Two Different Techniques, Anita Aminoshariae

Theses and Dissertations

AbstractTHE PLACEMENT OF MINERAL TRIOXIDE AGGREGATE USING TWO DIFFERENT TECHNIQUESBy Anita Aminoshariae, D.D.S.A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science at Virginia Commonwealth UniversityVirginia Commonwealth University, 2003Major Director: Gary R. Hartwell, D.D.S., M.S.Chairman and Professor, Department of EndodonticsThe purpose of this study was to determine if the adaptation of Mineral Trioxide Aggregate (MTA) to the walls of the samples would differ when placed into simulated root canals of varying length using two different placement and condensation methods. Hand condensation was compared to ultrasonic condensation. Eighty polyethylene tubes were divided into four groups …

Cleaning Efficiency Of Nickel Titanium Gt And .04 Rotary Files When Used In A Torque Controlled Rotary Handpiece, Calvin Buford Suffridge

Theses and Dissertations

This study determined if the cleaning efficiency of NiTi rotary files in an endodontic electric handpiece using a no torque control setting was superior to that obtained when using the torque control feature. Fifty extracted human anterior teeth with straight canals were divided into two groups of 20 and two control groups of 5. Canals were instrumented with GT and .04 Profile NiTi files until a size 35 advanced to working length. Samples were sectioned, the apical 6 mm of the canal was photographed (x20) and projected onto a 3 x 4 foot grid with squares measuring 0.5 inches each. …

Effect Of A Desensitizing Agent And An Adhesive System On Microleakage Associated With Cast Restorations Luted With A Resin-Modified Glass Ionomer Cement, Saleh Abdulaziz Al-Rowaieh

Theses and Dissertations

Purpose: This study evaluated microleakage associated with cast restorations that were luted with a resin-modified glass ionomer cement (RelyX) following obturation of the dentinal tubules with either a desensitizing agent (Gluma Desensitizer) or an adhesive system (Scotchbond Multipurpose Dental Adhesive). The effect of acid etching on the removal of the smear layer and its influence on the extent of microleakage associated with the adhesive system was also evaluated.

Materials and Methods: Extracted mandibular premolars (N = 48) were prepared for complete cast restorations and divided into 4 groups (N = 12). In group A ( control), neither a desensitizing agent …

Working Length Determination In Palatal Roots Of Maxillary Molars, Melanie A. Kim-Park

Theses and Dissertations

The aim of this study was to determine if a buccal curvature in the palatal roots of maxillary molars affected the clinician’s ability to accurately determine working length. Twenty-seven extracted, human maxillary molars were sorted by palatal root curvatures as J- and C-type and the angle of curvature was determined. Straight-line access was made and a #20 file was placed into the canal until the tip was visible at the apical foramen then withdrawn. The file, tooth and calibration wire were radiographed on one image using the RVG. Actual (file) and radiographic (tooth) lengths were determined using the RVG ruler. …

Alveolar Ridge Dimension Analysis Following Socket Preservation Using Clinical Assessment And Cone Beam Computed Tomography (Cbct)., Sayward Duggan

Theses and Dissertations

AIM: Extraction of a tooth can lead to alveolar ridge resorption which can be minimized by socket preservation. The aim of this study is to analyze vertical and horizontal alveolar ridge dimensions clinically and by CBCT immediately following extraction and 3-4 months following socket preservation. METHODS: The preserved group (P) consisted of 20 patients with1-2 non-molar teeth requiring extraction with socket preservation, while the control group (C) consisted of 5 patients requiring extraction alone. An acrylic stent was fabricated presurgically in order to measure vertical and horizontal ridge dimensions clinically and radiographically immediately following extraction and 3-4 months following socket …

Factors Considered By New Faculty In Their Decision To Choose Careers In Academic Dentistry, Harvey A. Schenkein, Al M. Best

Periodontics Publications

To determine the characteristics of new dental faculty and what factors influenced them to choose academic careers, a survey was sent to deans at all U.S. dental schools to be distributed to faculty with length of service of four years or less. Responses were received from 240 individuals. About half of the respondents had been in private practice for an average of eight years, and 20 percent had military experience averaging almost sixteen years. A majority had postgraduate training and 60 percent had specialty training. Nearly 32 percent of new faculty were female and 80 percent were U.S. citizens. Analyses …
