MEDLINE, EMBASE, and CENTRAL were searched for studies assessing implants that had been placed in nongrafted sites of irradiated patients. Random effects meta-analyses assessed implant loss in irradiated versus nonirradiated patients and in irradiated patients treated with hyperbaric oxygen (HBO) therapy. Of 1,051 potentially eligible publications, 15 were included. A total of 10,150 implants were assessed in the included studies, and of these, 1,689 (14.3%) had been placed in irradiated jaws. The mean survival rate in the studies ranged from 46.3% to 98.0%. The pooled estimates indicated a significant increase in the risk of implant failure in irradiated patients (risk ratio: 2.74; 95% confidence interval: 1.86, 4.05; p < .00001) and in maxillary sites (risk ratio: 5.96; 95% confidence interval: 2.71, 13.12; p < .00001). Conversely, HBO therapy did not reduce the risk of implant failure (risk ratio: 1.28; 95% confidence interval: 0.19, 8.82; p = .80). Radiotherapy was linked to higher implant failure in the maxilla, and HBO therapy did not improve implant survival. Most included publications reported data on [...]

The New Face of Oral Cancer

Source: nursing.advanceweb.comBy Jonathan BassettPosted on: April 22, 2013   For decades tobacco was the primary cause of oral cancer but a more insidious culprit has emerged.  Jerry Wilck had no reason to suspect anything. Why would he? He only smoked for a couple of years and gave it up more than 40 years ago. He didn't drink excessively, didn't have a family history of cancer, and took good care of himself. In fact, maybe the only reason the 59-year-old consulted an oral surgeon about the small sore on his tongue - the result of a habit of running this particular spot along his teeth - was that there happened to be such a specialist right there in his office. Wilck was a general practice dentist in Langhorne, Pa., and particularly attuned to anomalies of the soft tissues of the mouth. His oral surgeon took no chances and ordered a biopsy. Wilck was "floored" the night in March 2005 when the lab report arrived by fax from the oral pathology department at Temple University in Philadelphia - squamous cell carcinoma. Wilck immediately consulted with John Ridge, MD, PhD, FACS, chief of head and neck surgery at Temple's Fox Chase Cancer Center. After surgical removal of part of his tongue and lymph nodes from his neck, along with a round of physical and speech therapy, Wilck is now cancer free and has full use of his jaw, throat and voice. "I was lucky," confessed Wilck, who retired from practice in 2009 and now spends a [...]
