Antibiotic Use By Members Of The American Association Of Endodontics: A National Survey For 2009- A Follow Up From The Report In 1999, Pye Kyu
Theses and Dissertations
The purpose of this study was to determine the changes in prescribing habits of active members of American Association of Endodontics (AAE) with regards to antibiotics in comparison to the findings reported by Yingling et al. in 1999. The invitations to take the online survey were sent via email to 2593 active members. A response rate of 37.75% was obtained. It was determined to be adequate for analysis and for comparison to the results obtained by Yingling et al. Comparisons between the percentages shown in this survey and the previous survey were tested using a z-test. An ANOVA model was …
Frequency And Distribution Of Endodontically Treated Teeth, Hina Ahmed, Durr E. Sadaf, Munawar Rahman
Frequency And Distribution Of Endodontically Treated Teeth, Hina Ahmed, Durr E. Sadaf, Munawar Rahman
Section of Dental-Oral Maxillofacial Surgery
Objective: To determine the distribution and pattern of carious teeth involvement in permanent teeth requiring endodontic treatment. Study Design: Cross-sectional study. Place and Duration of Study: Dental Section of The Aga Khan University Hospital, Karachi, from September 2004 to March 2005. Methodology: Data was collected from the dental records of patients. Tooth was the unit of evaluation. Variables studied were demographics, tooth type, etiology of endodontic treatment and pattern of caries involvement. Data was analyzed using chi-square test and Fischer’s exact test. Results: The total number of patients was 190; total number of teeth involved were 235. Females had more …
Comparative Analysis Of Torsional Strength Between Profile® Gt® And Gt® Series X(Tm) Nickel Titanium Rotary Instruments, Jake Reynolds
Comparative Analysis Of Torsional Strength Between Profile® Gt® And Gt® Series X(Tm) Nickel Titanium Rotary Instruments, Jake Reynolds
Theses and Dissertations
The purpose of this study was to compare the resistance to fracture by the twisting of two nickel titanium (NiTi) rotary file systems. The Profile® GT® (GT) and the GT® Series X(TM) (GTX) files were tested to analyze the maximum torsional strength and the maximum angular deflection at the time of separation of the files. For each system, ten new files were tested at each of the following eight taper/size designations for a total of 160 files: 20/0.04, 20/0.06, 30/0.04, 30/0.06, 30/0.08, 40/0.04, 40/0.06, and 40/0.08. The American National Standards Institute / American Dental Association Specification No. 28 was implemented …
Comparing Cyclic Fatigue Of The New Gt® Series X(Tm) Files To The Endo Sequence™ Rotary Instruments, Nathan Wayment
Comparing Cyclic Fatigue Of The New Gt® Series X(Tm) Files To The Endo Sequence™ Rotary Instruments, Nathan Wayment
Theses and Dissertations
The purpose of this study was to examine the number of rotations to failure of two different rotary file systems, EndoSquence Brassler USA (Savannah, GA) and GT(TM) series X(TM). Files sizes 20,30,40 with 0.04, 0.06 tapers of GT series X and Endo Sequence files size and taper used were 20, 30, 40 with 0.04 and 0.06 taper. Like tip and tapers were compared between systems. All files tested were 25mm in length. Files were allocated into 12 groups of 10 files each, and mounted to a universal testing machine. Each file was rotated at 300 rpms until fractured occurred. The …
Comparing Cyclic Fatigue Of The New Gt® Series Xtm Files To The Original Profile® Gt® Rotary Instruments, Steven Osmond
Comparing Cyclic Fatigue Of The New Gt® Series Xtm Files To The Original Profile® Gt® Rotary Instruments, Steven Osmond
Theses and Dissertations
The purpose of this study was to test the number of rotations to fracture of the M-Wire GT® Series X(TM) rotary files compared to the original ProFile® GT® rotary files in a simulated curved canal. Eighty GT® Series X(TM) files of 25mm length were divided into eight groups of ten, one for each of the new GT® Series X(TM) files. Eighty original ProFile® GT® files of 25mm length were divided into eight groups of the same tip and taper sizes consistent with the GT® Series X(TM) file groups. Files were rotated at 300 rpm. While the angle may have slightly …
