FDA plans to reclassify safety of dental implant
Courthouse News Service
From Jan. 18: The Food and Drug Administration plans to reclassify a blade-form surgically implanted dental device, citing the benefits of such devices relative to their risks. The blade-form endosseous dental implant is a kind of device, made of titanium alloy or other so-called biocompatible material, that is surgically installed into a patient's jaw bone. A denture, crown, bridge or similar dental restoration is attached to the implant by means of a screw extending into the patient's mouth, the proposal states.More

Dentist invents new technique to treat gum recession
From June 24: While painful surgery used to be the only way to treat receding gums, one dentist is trying another way. Dr. John Chao has developed a new, nearly painless procedure called the pinhole surgical technique to help those with gum recession. Gum grafting, the conventional treatment of choice for receding gums, is painful. Dentists cut and remove tissue from the roof of the mouth and then graft it onto the receded gum.More

Is mouthwash really beneficial to oral health?
The Inquisitr
From June 18: Many people use mouthwash as an integral part of their oral hygiene regime — sold on the marketed concept that the minty concoction can effectively kill germs and slake halitosis, perhaps even more so than brushing the way some ads read. Mouthwash is marketed as a highly effective product for warding off harmful bacteria responsible for gum disease and decay. But does the use of mouthwash benefit overall oral hygiene the way it's advertised to?More

A new tool in the fight against peri-implant disease
Surgical Restorative
From April 24: Peri-implant disease has been defined as an inflammatory process affecting the hard and/or soft tissues surrounding an implant in function. Peri-implant diseases can be broken down further into two entities: peri-implant mucositis and peri-implantitis. Peri-implant mucositis has been described as a disease in which the presence of inflammation is confined to the soft tissues surrounding a dental implant with no loss of supporting bone following initial bone remodeling. Peri-implantitis on the other hand has been characterized by an inflammatory process around an implant, which includes both soft tissue inflammation and progressive loss of supporting bone beyond biological bone remodeling.More

LeAnn Rimes suing dentist, says his bad work made her career suffer
ABC News
From Feb. 16: LeAnn Rimes is suing her dentist, alleging that his poor dental work is the reason her career has stalled. The singer is seeking monetary compensation for "loss of earnings and future earning capacity" as well as for the physical, emotional and psychiatric injuries she sustained over a three-year period of treatment, according to court documents.

Is it time to retire the free gingival graft procedure in light of new alternative tissue grafting materials?
Surgical Restorative
From May 22: The free gingival graft is a surgical procedure frequently used in periodontics to increase the amount of keratinized tissue surrounding a tooth or a dental implant. Keratinized tissue plays a major role (around teeth and dental implants), helping to maintain and facilitate oral hygiene. This surgical technique was introduced almost 50 years ago in 1966.More

4 ways to handle the inevitable negative review
The Huffington Post
From July 18: Jay Gierak writes, "My dentist once had a customer slander him on Yelp in an effort to get out of a bill. He asked if I could help, hoping I might know someone at Yelp fix the problem. The review persisted online for years, as did my dentist's pleas for help. My dentist's story is not uncommon. Negative reviews from unhappy customers, peeved ex-employees or close competitors are a challenge for local businesses, legitimate or not."More

Dentists say you need to floss. Science says you don't.
From Oct. 17: While working as a research fellow at the Primate Research Institute at the University of Kyoto in Japan, French ethologist Jean-Baptiste Leca witnessed a sight that would prompt a toothy smile from any dentist. One day, a 14-year-old female Japanese macaque named Chonpe plucked a string of hair, stretched it taut between her hands, and ran the strand between her teeth. She was flossing.More

Underlying mechanisms behind chronic inflammation-associated diseases revealed
From Feb. 22: Inflammatory response plays a major role in both health protection and disease generation. While the symptoms of disease-related inflammatory response have been know, scientists have not understood the mechanisms that underlie it. In a paper published Feb. 21 in Cell Reports, a team lead by Xian Chen, associate professor of biochemistry and biophysics and member of the UNC Lineberger Comprehensive Cancer Center, mapped the complex interactions of proteins that control inflammation at the molecular level.More
