Comprehensive Review Of Current Endodontic Sealers, Takashi Komabayashi, David Colmenar, Nicholas Cvach, Aparna Bhat, Carolyn Primus, Yohji Imai

Dental Medicine Faculty Publications

Endodontic sealers for non-surgical root canal treatment (NSRCT) span many compositions and attributes. This comprehensive review discusses current types of endodontic sealers by their setting reaction type, composition, and properties: zinc oxide-eugenol, salicylate, fatty acid, glass ionomer, silicone, epoxy resin, tricalcium silicate, and methacrylate resin sealers. Setting time, solubility, sealing ability, antimicrobial, biocompatibility, and cytotoxicity are all aspects key to the performance of endodontic sealers. Because sealing ability is so important to successful outcomes, the relative degree of microleakage among all the relevant sealers was calculated by way of a meta-analysis of relevant literature.

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

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 …
