Stem cell therapy could offer new hope for defects and injuries to head, mouth
In the first human study of its kind, researchers found that using stem cells to re-grow craniofacial tissues — mainly bone — proved quicker, more effective and less invasive than traditional bone regeneration treatments.

University of Helsinki via ScienceDaily
To build a tooth, a detailed recipe to instruct cells to differentiate toward proper lineages and form dental cells is needed. Researchers in the group of professor Irma Thesleff at the Institute of Biotechnology in Helsinki, Finland, have now found a marker for dental stem cells. They showed that the transcription factor Sox2 is specifically expressed in stem cells of the mouse front tooth.More

Study: More postoperative pain with propofol/remifentanil
While the use of propofol and remifentanil are increasing in orthognathic surgery, patients may experience more postoperative pain than with other types of anesthesia, according to a study in Anesthesia Progress. Remifentanil increasingly is used in orthognathic surgery because its short half-life can facilitate stable operating conditions while avoiding the undesirable postoperative consequences of morphine and other such agents, according to lead author Soudeh Chegini, from Heatherwood and Wexham Park Hospitals NHS Foundation Trust, and colleagues.

Antioxidants and oral health
Inside Dental Assisting
It's global and around the clock, driven by rapidly expanding news, Internet, and social media outlets.

It often falls on oral healthcare providers to separate the science from the spin, to help our patients develop their health literacy and critical eye. Because dental team members are well versed in evidence-based dentistry and peer-reviewed research, they can offer their patients more grounded information.More

Gum disease more common with old age
Teeth Removal
A recent study in Nature Immunology shows that the deterioration in gum health that occurs with increasing age is associated with a drop in the level of a chemical called Del-1. Periodontitis is a disease of the gums that causes bleeding and bone loss which can, over time, lead to loss of teeth. Periodontitis is caused by an overactive immune response to bacteria that grow in the mouth.More
