Systematic Review: Bisphosphonates and Osteonecrosis of the Jaws

TL;DR: Osteonecrosis of the jaws is strongly associated with the use of aminobisphosphonates, and the mechanism of disease is probably severe suppression of bone turnover, and possible mechanisms of etiopathogenesis are suggested.
Journal ArticleDOI

Bisphosphonate osteochemonecrosis (bis-phossy jaw): is this phossy jaw of the 21st century?

TL;DR: Bis-phossy jaw may have more of a bacterial cofactor risk than osteoradionecrosis, and though altered angiogenesis may yet prove to be a factor, avascularity does not appear to beA major cofactor.
Journal ArticleDOI

A comparison of the cleaning efficacy of short-term sonic and ultrasonic passive irrigation after hand instrumentation in molar root canals.

TL;DR: Passive sonic or ultrasonic irrigation, for as little as 30 s, resulted in significantly cleaner canals than hand filing alone, when sonic and ultrasonic passive irrigation were compared with only each other.
Journal ArticleDOI

Updated recommendations for managing the care of patients receiving oral bisphosphonate therapy: an advisory statement from the American Dental Association Council on Scientific Affairs.

TL;DR: For patients receiving bisphosphonate therapy, the risk of developing bisph phosphonate-associated osteonecrosis of the jaw apparently remains low and it newly concludes that current screening and diagnostic tests are unreliable for predicting a patient'srisk of developing the condition.
