Stem cells from fat used to grow teen's missing facial bones
Scientific American
Stem cells so far have been used to mend tissues ranging from damaged hearts to collapsed tracheas. Now the multifaceted cells have proved successful at regrowing bone in humans. In the first procedure of its kind, doctors at Cincinnati Children's Hospital Medical Center replaced a 14-year-old boy's missing cheekbones—in part by repurposing stem cells from his own body. More

Dallas facial plastic surgeon publishes cutting-edge novel approach to facelift technique
PR Web
Director of the Advanced Facial Plastic Surgery Center in Dallas, Dr. Benjamin Bassichis is a double-board certified facial plastic surgeon specializing exclusively in cosmetic procedures of the face. Dr. Bassichis recently published a landmark article in the Facial Plastic Surgery Clinics of North America documenting his modern approach to truly rejuvenating facial surgery. Underlying the novel surgical technique presented in his manuscript entitled "Volumetric Facelift with Intra-operative and Post-operative Dermal Filler Midface Volume Replacement for Natural, Long-term Full Face Rejuvenation: The Four-Dimensional Facelift," is an in-depth understanding of the intrinsic, un-ceasing maturation process of the face. While previous facelift techniques focused on tightening loose skin and lifting fallen tissues, the majority did not address facial volume loss.More

Dentists your first defense in fight against oral cancer
Edmonton Journal via The Vancouver Sun
In 2003, an estimated 3,100 Canadians were newly diagnosed with oral cancer. That same year, 1,090 people died of the disease. In the U.S., oral cancer kills roughly one person per hour, 24 hours a day. Of those newly diagnosed, only half will survive five years later,and this terrifying death rate has not declined for decades. Those statistics are frightening, but the good news is that early detection plays a major role in preventing or curing oral cancers. The first line of defense is the dentist. They are specifically trained to recognize even subtle changes in the mouth and take action.More

AlloDerm grafting: Class III recession with cervical notching
Osseo News

This surgical video shows AlloDerm grafting using the Papilla Retention Pouch procedure to treat Class III recession in the mandibular arch. The recession is complicated by the presence of cervical notching and restorations. Use of the new end-cutting intrasulcular knife for the initial incision is demonstrated. Root preparation with a Varios 750 ultrasonic unit and a special safe-sided diamond tip is shown for reshaping the notched root surfaces following blunt reflection. More

Comparison of the cytotoxicity of calcium hydroxide and tricalcium phosphate
Dentistry IQ
Cytotoxic impacts of calcium hydroxide and tricalcium phosphate, which are used in endodontics, have been examined in cell cultures. VERO (African Green Monkey Kidney Cell) has been used as cell culture for the cytotoxicity assessment of calcium hydroxide and tricalcium phosphate. Morphology changes, rounding and grouping of cells, have been taken into account during toxicity assessment. Toxic impact has been observed in pure concentration of tricalcium phosphate, but no toxic impact has been observed in pure concentration of calcium hydroxide when cytotoxic impacts of calcium hydroxide and tricalcium phosphate have been examined.More

Form of mercury in older dental fillings unlikely to be toxic
Medical News Today
Amid the on-going controversy over the safety of mercury-containing dental fillings, a University of Saskatchewan research team has shed new light on how the chemical forms of mercury at the surface of fillings change over time. Their work, just published in the American Chemical Society journal Chemical Research in Toxicology, shows that the surface forms of mercury in older "silver" fillings (also known as amalgams) may be less toxic than previously thought.More

Hospice hygiene
RDH Magazine
In the United States, a majority of people die from chronic degenerative diseases (Lynn, 1996). As the population ages and the incidence and prevalence of chronic conditions are widespread, patients’ needs are increasing in their complexity. Patients referred to palliative and hospice care are quickly becoming debilitated by the nature of their serious or life-threatening illness. Owing to advanced chronic conditions (e.g., neurological, cardiac, or respiratory diseases) or malignancies, oral care can threaten the quality of life, complicate care, and increase the cost of care.More

Treating oral histoplasmosis in an immunocompetent patient
Journal of the American Dental Association
Histoplasmosis is a deep fungus infection that occurs worldwide and is caused by Histoplasma capsulatum. Oral histoplasmosis has been of considerable importance in recent years because it occurs frequently in immunosuppressed patients, more often in those who test positive for the human immunodeficiency virus. However, the literature contains reports of histoplasmosis in immunocompetent patients, especially in endemic areas.More

Hypersensitive teeth: Conventional vs. Laser treatment
The Journal of Oral Laser Applications
Dentin hypersensitivity is a painful response to a non-noxious stimulus applied to exposed dentin. Two processes may expose dentin: loss of enamel and/or loss of cementum. Loss of enamel occurs by attrition associated with occlusal function, by abrasion from dietary components or incorrect tooth brushing, or by erosion associated with environmental or dietary components, particularly acids. Exposure of root dentin is also multifactorial. Periodontal disease with gingival recession, some forms of periodontal surgery, and overzealous brushing are important etiological factors that expose root dentin.More
