Achieving Dentin Conservation Using Dynamic Navigation Technology For Locating Calcified Canals, Madison W. Saunders

Theses and Dissertations

Purpose: Pulp canal obliteration (PCO) is a common sequela of dental trauma, caries, restorations and vital pulp therapy procedures. Despite the application of high magnification and CBCT imaging, access cavity preparation for such cases is prone to procedural errors that may lead to substantial loss of dentin structure thereby reducing the long-term prognosis. This study aimed to achieve dentin conservation using a novel computer assisted dynamic navigation system (Navident) in comparison to freehand access preparation for locating calcified canals.

Methods: Forty maxillary and mandibular central incisors (tooth #9 and tooth #25) were 3-D printed to simulate PCO. They were randomly …

Fracture Resistance Of Simulated External Cervical Resorption In Anterior Teeth Restored With And Without A Fiber Post., Michelle M. Romeo

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: External cervical resorption (ECR) is a destructive type of external resorption that can be difficult to treat. ECR usually begins subgingival at the cementoenamel junction of teeth and continues apically and circumferentially. This substantial loss of tooth structure may make these teeth more prone to fracture and should be addressed when treatment planning teeth with ECR. The aim of this in vitro study was to evaluate the fracture resistance of treated and non-treated teeth with simulated ECR using two different treatment modalities.

Materials and Methods: Forty-eight extracted human permanent mandibular central incisors were selected. Teeth were randomly divided into …

Prevalence Of Enterococcus Faecalis And Candida Albicans In Teeth Requiring Endodontic Retreatment, Sopida Thipung

Chulalongkorn University Theses and Dissertations (Chula ETD)

Endodontic failures are mainly caused by persistence of microorganisms in the root canal system. Enterococcus faecalis has been reported as the most commonly isolated species from root canals with endodontic treatment failure in many studies, but was not the dominant species in others. Recent studies showed that Candida albicans is found together with Enterococcus faecalis within infected root canals in a polymicrobial community and both species can form biofilm. Therefore, this study aims to investigate the prevalence of Enterococcus faecalis and/or Candida albicans in root canals requiring retreatment by using both culture-based and polymerase chain reaction (PCR) techniques, and examine …
