Research Summary Regenerative medicine: Isolating stem cells from teeth Adult stem cells in dental pulp can be isolated via a single surface protein and efficiently grow into various cell types. It has been a matter of debate how best to isolate these cells so that they retain the ability to develop into various specialized tissues....

Research Summary Dental implants: different materials for different tissues The risk of infection may be reduced by constructing dental implants from combinations of materials that resist bacterial growth. Microbes can potentially form antibiotic-resistant biofilms on the surface of implants, particularly if the surrounding tissue does not form a tight seal. Researchers led by Yijin Ren...

Research Summary Oral fibrosis: Low-power laser for disease associated with areca nut Low-power laser irradiation (LPLI) could treat a debilitating pre-malignant, fibrotic condition of the mouth. Most cases of oral submucous fibrosis (OSF) are in South Asia and are associated with areca nut chewing. The compound arecoline in the nut is thought to be involved...

Research Summary Oral clefts: Distinct genetic profiles characterize subtypes Oral clefts: Distinct genetic profiles characterize subtypes. Oral cleft subtypes are characterized by distinct gene profiles that may reflect differing genetic causes. Oral clefts, the most common congenital defect in humans, are associated with a large number of genes. Noriko Funato and Masataka Nakamura at the...

Research Summary Root canal surgery: Ensuring a cleaner finish Using citric acid in combination with ultrasonic rinsing helps flush out root canals prior to completing treatment. Calcium hydroxide, Ca(OH)2, is used to eliminate microbes from root canals during treatment. However, residual Ca(OH)2 left behind once treatment is complete can reduce the effectiveness of sealants and weaken...

Research Summary Periodontitis: A novel technique for delivering therapeutics A combination of tiny gas-filled bubbles and ultrasound radiation can be used to deliver anti-inflammatory agents into periodontal tissue. The treatment produces pores in the surface of cells, facilitating the passage of therapeutics. Yuji Ishida of the Tokyo Medical and Dental University and collaborators successfully used...
