This Post is adapted from the Canadian Pharmacists Association (CPhA) Drug Monograph: Biphosphonates Product Summary Pharmacology Bisphosphonates (previously called diphosphonates) are stable analogues of pyrophosphate. After binding to bone surfaces, they slow the formation of hydroxyapatite crystals and delay their aggregation into large clusters. They also interfere with the resorptive action and promote apoptosis (programmed cell death) of osteoclasts, resulting in decreased depth and rate of formation of new bone remodeling units. Lifelong accumulation of remodeling deficits begins shortly after bone growth stops and is thought to be the underlying mechanism of age-related bone loss. By inhibiting this process, bisphosphonates ...Read More »

Should the transmission (gears) inside prophy heads and slow speed hand pieces be sterilized between patients?
This question was submitted by a general dentist: “Should the transmission (gears) inside prophy heads and slow speed hand pieces be sterilized between patients?
