Endodontics Insider: Lesions in the periradicular area may be nonendodontic

Dear Endodontics Insider,

The chances of encountering nonendodontic lesions in periradicular tissues are nearly 8%, and up to 3% of biopsies conducted on teeth with pulp necrosis were confirmed to not be of an endodontic origin, according to a study published earlier this month in the Journal of Endodontics.

Following successful endodontic treatment, air blown from a turbine drill became trapped in a major facial vein of a healthy woman during dental crown preparation, which could have led to deadly complications. The woman experienced this on two separate occasions, according to a recent case report.

In other news, human-digested dentin matrix extract may be used as a biomaterial for dentin regeneration, making it a possible option for vital pulp therapy like pulpotomy. This animal study was published in the Journal of Endodontics

Also in our Endodontics Community, imaging aided in the management of a man’s atypical root canal anatomy in which the distobuccal canal of his second molar was close to the palatal root canal with partially fused roots. The clinical exam and imaging findings helped the man receive appropriate endodontic treatment for pulpal necrosis with symptomatic apical periodontitis.

Did you know that nearly half of patients who sought root canal treatment for a painful tooth had temporomandibular joint disorders (TMDs)? TMDs were partly or solely the cause of the pain in 25% of patients, according to the study's authors.
