Deformation and fracture incidence of Reciproc instruments: a clinical evaluation.

submitted by: gplotino
Aim To investigate the incidence of fracture and deformation observed on Reciproc instruments after clinical use. Methodology A total of 1696 Reciproc NiTi instruments that were discarded after normal clinical usage over 30 months were collected, 1580 instruments were R25 (93%), 76 were R40 (5%) and 40 were R50 (2%). The treatments included 3780 root canal preparation, 3023 primary treatments and 757 retreatments. Root canal preparation was standardized and followed the manufacturer's...

Cancer and teeth

submitted by: mdanderson
Attentive dental care is critical for cancer patients. Before beginning cancer treatment, patients should address pre-existing oral conditions and infections. During treatment, conditions may arise, such as chemotherapy-induced oral mucositis (mouth lining breaks down forming ulcers); xerostomia (dry mouth); and poor blood flow which may result in bone rot causing jaw fractures. It’s important for cancer survivors to see their dentists regularly, too. Mark Chambers, D.M.D., professor in...

Multiple myeloma – blood cancer formed in bone marrow

submitted by: mdanderson

Multiple myeloma is a cancer caused by malignant plasma cells. Plasma cells help the human body fight infection, but when they multiply out of control, the myeloma cells overpower the bone’s healthy cells causing harmful side effects; such as bone fractures and infections. Sheeba Thomas, M.D., assistant professor in Lymphoma/Myeloma at MD Anderson Cancer Center, discusses the basics, risk factors, diagnosis and treatment options for this rare cancer.

Dietary Intake of Arachidonic Acid and alpha-Linolenic Acid are Associated with Reduced Risk of Hip Fracture in Older Adults

submitted by: emily.farina
PUFA are hypothesized to influence bone health, but longitudinal studies on hip fracture risk are lacking. We examined associations between intakes of PUFA and fish, and hip fracture risk among older adults (n = 904) in the Framingham Osteoporosis Study. Participants (mean age ~75 y at baseline) were followed for incident hip fracture from the time they completed the baseline exam (1988-1989) until December 31, 2005. HR and 95% CI were estimated for energy-adjusted dietary fatty acid...
