What is the incidence and related factors of middle mesial canals in mandibular molars?

This summary is based on the article published in the Journal of Endodontics: Middle Mesial Canals in Mandibular Molars Incidence and Related Factors (January 2015) Ali Nosrat, DDS, MS, Raney J. Deschenes, DMD, MS, Patricia A. Tordik, DMD, M. Lamar Hicks, DDS, MS, and Ashraf F. Fouad, BDS, DDS, MS Context The aim of root canal therapy is to eliminate all irritants from the root canal system. These irritants include necrotic pulp tissue, microorganisms, and their byproducts. A detailed knowledge of the pulp canal anatomy is necessary to effectively clean and shape the root canal system. Mandibular molars are the ...

Comparing the survival rate of intentionally replanted teeth and implant-supported single crowns. A systematic review

This summary is based on the article published in the Journal of Endodontics: Survival of Intentionally Replanted Teeth and Implant-supported Single Crowns: A Systematic Review (July 2015) Mahmoud Torabinejad, DMD, MSD, PhD, Nathan A. Dinsbach, DDS, MSD, Michael Turman, DDS, MSD, Robert Handysides, DDS, Khaled Bahjri, MD, MPH, and Shane N. White, BDentSc, MS, MA, PhD Context Nonsurgical root canal treatment (NSRCT) provides high long-term survival and success rates (1–4), allowing millions of people to preserve their natural dentitions. Although nonsurgical initial root canal treatment and retreatment have high success rates, periapical disease can remain (5–7). Additionally, successfully treated teeth ...

Bioceramic materials in endodontics

This summary is based on the article published in Endodontic Topics: Bioceramic materials in endodontics (May 2015) Zhejun Wang Courtesy of Wiley Publishing, you can access the full-text article for the next 3 months (PDF)   Context During the past two decades, a number of major advances have been made in the field of bioactive ceramics used for endodontic treatment. Bioceramic materials, with their biocompatible nature and excellent physico-chemical properties, are widely used in endodontic applications. They can function as cements, root repair materials, root canal sealers and filling materials, which have the advantages of enhanced biocompatibility, potential increased root ...

What is the process of internal resorption and what is the necessary treatment?

What is the process of internal resorption and what is the necessary treatment?   Internal resorption begins on the internal dentin surface and spreads laterally. It may or may not reach the external tooth surface. The process is often asymptomatic and becomes identifiable only after it has progressed enough to be seen radiographically. The cause is unknown. Trauma is often but not always implicated. Resorption that occurs in inflamed pulps is characterized histologically by dentinoclasts, which are specialized, multinucleated giant cells similar to osteoclasts. Treatment is prompt endodontic therapy. However, once external perforation has caused a periodontal defect, the tooth is often lost. Source: Dental Secrets, ...

Should retention of a tooth be an important goal of dentistry?

This summary is based on the article published in the Australian Endodontic Journal: Should retention of a tooth be an important goal of dentistry? (April 2015) Jessica J. Zachar Context Whether a questionable tooth should be treated endodontically or extracted, is still a dilemma that clinicians encounter every day. With advances in technology such as implantology, deciding whether or not to save a tooth is still not clear. Local site-specific factors and patient-related factors that may affect the longevity of a particular tooth should be considered in preparing the treatment plan. Long-term success rates for root canal therapy and implant-supported ...

Are more conservative root canal preparations and smaller tapered files better in preserving tooth structure during endo?

This question was submitted by a general dentist:  Are more conservative root canal preparations and smaller tapered files better in preserving tooth structure during endo? The trend seems to be shifting from large tapers(0.8.0.6) occlusally, plus large size files(30, 35) in order to facilitate access of irrigants and flushing into the depths back to keeping the canals narrow in order to preserve tooth structure and prevent fractures etc.  Do please advise. Dr. Mary Dabuleanu from Dabuleanu Dental and Dr. Suham Alexander provided this quick initial response:  It has been suggested that smaller access preparations and smaller tapered rotary files allow for more ...
