Outcomes Of Primary Endodontic Therapy Provided By Endodontic Specialists Compared To Other Providers, Jacob Burry
Outcomes Of Primary Endodontic Therapy Provided By Endodontic Specialists Compared To Other Providers, Jacob Burry
Master's Theses (2009 -)
Introduction: The objective of this study was to compare the outcomes of initial non-surgical root canal therapy (NSRCT) for different tooth types provided by both endodontists and other providers. Methods: Using an insurance company database, 487,476 initial NSRCT procedures were followed from the time of treatment to the presence of an untoward event indicated by Current Dental Terminology (CDT) codes for retreatment, apical surgery, or extraction. Population demographics were computed for provider type and tooth location. Kaplan-Meier survival estimates were calculated for 1, 5, and 10 years. Hazard ratios for provider type and tooth location were calculated using the Cox …
Viability Of Human Periodontal Ligament Fibroblasts After Storage In Save-A-Tooth, Emt Toothsaver And Hank's Balanced Salt Solution, Wonhee Lee
Master's Theses (2009 -)
Introduction: Viability of periodontal ligament (PDL) cells is a key prognostic factor fora replanted tooth following avulsion. Dehydration results death of PDL cells, which in turn causes ankylosis upon replantation, followed by replacement resorption. Hank’s Balanced Salt Solution (HBSS) has been recommended as the standard storage medium for an avulsed tooth. Save-A-Tooth and EMT Tooth saver (Dentosafe)are commercially available tooth storage media. With the best of our knowledge no study has yet compared these media for their effective tooth storage times. The aim of this invitro study is to evaluate Save-A-Tooth, EMT Toothsaver (Dentosafe), and HBSS for their effect on …
Torsion And Bending Properties Of Edgeendo Files, Chad Hansen
Torsion And Bending Properties Of Edgeendo Files, Chad Hansen
Master's Theses (2009 -)
Introduction: One important step of root canal therapy is the process of cleaning and shaping each canal. This process involves using endodontic rotary files combined with chemical irrigants to remove pulpal remnants and infected dentin from the canal while eliminating pathogenic bacteria. It is essential to maintain proper canal anatomy while cleaning and shaping. The challenge for the practitioner is to select a rotary file system that will be flexible enough to maintain canal anatomy but strong enough to prevent breakage under normal use. File flexibility allows for better maintenance of canal anatomy. A file’s resistance to torsional fatigue reduces …
