Can autofluorescence find bacterial contamination in root fractures?
July 17, 2019 -- When looking for root fractures, conventional scanning methods may miss crucial clinical information. Researchers wanted to see if a fluorescence camera could measure the depth of these fractures and any bacterial presence in extracted mandibular second molars.  Discuss
For patients, root canals are like pulling teeth
July 15, 2019 -- What's the worst dental procedure? It may not be root canals. The treatment faired about the same as extractions and prosthodontic services in a recent study examining oral health-related quality of life.  Discuss
How strong are the antimicrobial effects of endo sealers?
July 1, 2019 -- The antimicrobial activity of endodontic sealers can be important to the outcome of root canal treatment, but the amount of information available on their antimicrobial abilities varies. To learn more, investigators evaluated four sealers using two testing methods and found antimicrobial activity in three of them.  Discuss
Study tests imaging modalities' accuracy on root canal anatomy
May 15, 2019 -- Correctly identifying the anatomy of a root canal is crucial for successful endodontic therapy. Researchers tested cone-beam CT and periapical radiography to see if either was more accurate than microcomputed tomography. They reported that practitioners should be aware of each modality's limitations.  Discuss
Can MRI compete with CBCT to identify tooth fractures?
May 10, 2019 -- While magnetic resonance imaging (MRI) is often used for injuries of the knee and other body parts, researchers wanted to see if recent improvements in the modality meant it could be used to identify root cracks and fractures in teeth. They compared it with cone-beam CT (CBCT) to find out.  Discuss
New research focuses on endo pain relief issues
April 12, 2019 -- New research on pain control and management for patients was presented on April 11 at the 2019 American Association of Endodontists annual meeting in Montreal. The presentations included research on the use of photodynamic therapy, persistent pain after root end surgery, and the link between depression and postoperative pain.  Discuss

Getting to the root of dentinal defects

Do newer instruments for preparing root canals induce small dentinal defects that can lead to root fractures, or have improvements in nickel titanium alloys alleviated this potential problem? Since the evidence is unclear, a new study used microcomputed tomography to analyze dentinal defects in root canals prepared with various instruments. Read more.
