Removal Of Endodontic Fiber Posts Using Robot-Assisted Haptic Guidance: A Novel Approach, Joshua Dale
Removal Of Endodontic Fiber Posts Using Robot-Assisted Haptic Guidance: A Novel Approach, Joshua Dale
MUSC Theses and Dissertations
Introduction: Fiber posts are frequently used for the restoration of endodontically treated teeth. Such posts are typically bonded to the tooth using a composite resin system. These posts often need to be removed during endodontic retreatment. While there are many techniques to remove fiber posts, most include drilling through the post itself which can be challenging and result in a perforation or excessive tooth structure being removed. Static and dynamic guided endodontic techniques have been proposed to safely remove fiber posts. Yomi (Neocis, Inc, Miami, FL) is a haptic robot guidance system has been FDA approved to assist in placing …
Comparison Of Accuracy And Efficiency Of Robotic-Assisted Haptic Guidance Versus Freehand Access Preparation In Calcified Teeth, Roshanak Momen
Comparison Of Accuracy And Efficiency Of Robotic-Assisted Haptic Guidance Versus Freehand Access Preparation In Calcified Teeth, Roshanak Momen
MUSC Theses and Dissertations
Introduction: The initial step of root canal therapy consists of access preparation. Access preparation can be difficult, due to pulpal calcifications, misaligned teeth, and full coverage restorations that obscure the canal morphology. Recent trends involve static or dynamic guides to help the operator to locate the canals. Both systems have limitations. A robot with haptic guidance has been developed for implant surgeries, however, no studies have evaluated its possible use in endodontics. The purpose of this study was to determine whether the volume of tooth structure removed, and time required for access preparation in calcified anterior teeth differed between a …
Removal Of Endodontic Fiber Posts Using Dynamic Guidance: A Novel Approach, Scott Joseph Loomis
Removal Of Endodontic Fiber Posts Using Dynamic Guidance: A Novel Approach, Scott Joseph Loomis
MUSC Theses and Dissertations
Introduction: Retreatment of root canals often involves removal of obstructions. Commonplace are fiber posts that have been placed that require drilling of the post to gain access to the root canal system. Guided endodontic procedures, and more specifically Dynamic Guidance is an emerging field in dentistry. Objective: To determine whether dynamic navigation instrumentation is more accurate and more efficient at bonded fiber post removal than free-hand removal. Materials and Methods: Thirty maxillary incisors were treated endodontically using the ProTaper Gold system and obturated with warm vertical compaction. Post space was prepared and size 2 fiber posts were bonded into the …
Accuracy Of Dynamic Guidance System In Endodontic Access Of Anterior Teeth - Ex Vivo Analysis, Kyan Salechi
Accuracy Of Dynamic Guidance System In Endodontic Access Of Anterior Teeth - Ex Vivo Analysis, Kyan Salechi
MUSC Theses and Dissertations
Aim: To measure the accuracy, we will be evaluating the position deviations and angular deviations of endodontic access preparations compared with the digital file plan for the guided access. Material and Methods: 24 extracted human anterior teeth (4 maxillary canines, 4 mandibular canines, 8 mandibular incisors, and 8 maxillary incisors) were mounted into acrylic resin to mimic the position in the human jaw. Pre-op CBCT images of the models were acquired and imported into the X-Nav system software. Virtual endodontic files were custom created in the software by adjusting the diameter of the “implant” to 0.5 mm, with lengths ranging …
Endodontic Residents: Factors Influencing The Decision To Become A Dental Educator, Lauren E. Kuhn
Endodontic Residents: Factors Influencing The Decision To Become A Dental Educator, Lauren E. Kuhn
MUSC Theses and Dissertations
Significance and Introduction: Dental schools in the United States are faced with a shortage of faculty. Endodontic residencies and pre-doctoral clinics are not immune to the faculty scarcity. The purpose of this study was to assess factors that influence endodontic residents’ decisions on whether to pursue a career as a dental educator. This information may be used to inform future recruitment and retention efforts for endodontic faculty. Materials and Methods: All United States American Association of Endodontists (AAE) members designated as “resident members” (525) were sent an electronic survey. The survey included demographic data, and factors impacting their career decisions. …
Development And Verification Of Desktop Printed 3-Dimensional Guides For Angulation And Depth Controlled Conservative Endodontic Access, Bryce Ryszard Szczepanik
Development And Verification Of Desktop Printed 3-Dimensional Guides For Angulation And Depth Controlled Conservative Endodontic Access, Bryce Ryszard Szczepanik
MUSC Theses and Dissertations
Introduction: Recent studies have shown that conservative endodontic cavities (CECs) have a higher mean load at fracture in molars and premolars compared to traditional access cavities, however, performing these CECs can be challenging for the practitioner. Microguided endodontic access is a reliable means of preserving dentin while gaining access to the pulp chamber. The aim of this study was to 1. Develop a protocol for designing angulation and depth controlled physical guides to perform endodontic access, and 2. To compare its ability to provide straight line access against a decoronated tooth, measuring angle of deflection of inserted files. Materials and …
Survey Of Cone-Beam Computed Tomographic Use Among General Dentists, Katherine Marie Mckitrick
Survey Of Cone-Beam Computed Tomographic Use Among General Dentists, Katherine Marie Mckitrick
MUSC Theses and Dissertations
Introduction: The use of CBCT in endodontics has been gaining momentum with the awareness of its advantages over conventional periapical radiographs. Many specialty endodontic practices have incorporated the use of this technology into their practices and use it on a routine basis for endodontic diagnosis and treatment planning. Other dental specialties and general dentists are also recognizing the advantages of this technology and adopting it into their practices. The purpose of this study was to determine general dentist’s use and knowledge of CBCT and if a CBCT machine in an endodontist’s office affects their referral pattern. Materials & Methods: An …
Copper Iodide Augmented Gutta-Percha Significantly Limits The Growth Of Enteroccocus Faecalis, Monica Rancourt Estes
Copper Iodide Augmented Gutta-Percha Significantly Limits The Growth Of Enteroccocus Faecalis, Monica Rancourt Estes
MUSC Theses and Dissertations
Introduction: The primary goals of endodontic therapy are the elimination of microorganisms in the root canal system, resolution of pulpal and periradicular disease, and retention of a functional tooth. Chemo-mechanical debridement is the foundation of · bacterial reduction in current endodontic protocol. Biomedical research has revealed that metallic nanoparticles have shown great promise in killing bacteria. This in vitro study aimed to investigate the potential effect of copper iodide (Cul) on Enterococcus faecalis when nanoparticles are impregnated in gutta-percha obturation materials. Materials and Methods: Cul nanoparticles were incorporated into gutta-percha via thermoplastic deformation and ultrasonic processing achieving final concentrations of …
