Dental sealants that contain the element selenium may prevent caries-causing bacteria from forming on and below sealed teeth, possibly paving a new way to halt tooth decay, according to a study published in Dental Materials. Read more in our Insider Exclusive.

Also in the Restoratives & Cosmetics Community, a 51-year-old man unintentionally swallowed a dental crown, resulting in an unusual case of appendicitis caused by ingestion of a foreign body, according to a recent case report.

Finally, an analysis of cone-beam computed tomography scans found antihypertensive drugs may positively affect the thickness of the jawbone cortex by possibly preventing bone loss. If more research proves that these medications have the potential to improve the density and cortical thickness of the jaw, clinicians may change how they assess and select patients for treatment, including dental implant therapy.
