A review of dental treatment of head and neck cancer patients, before, during and after radiotherapy: part 2.

The incidence of head and neck cancer is on the rise. Radiation therapy is one of the major treatment modalities for the management of oral malignancies. As with any treatment modality, radiation therapy is associated with various complications. The second part of this series is a review of the oral changes that occur during and after radiotherapy and the oral management of head and neck oncology patients before, during and after radiotherapy. Dental practitioners will encounter patients who have been affected by cancer or who are current cancer patents. General dental practitioners (GDPs) have a vital and proactive role in supporting such patients. The aim of this article is to review the oral management of these patients during and after radiotherapy, and gives practical advice for GDPs and their teams in the long-term care of these patients

Periodontal status and bacteremia with oral viridans streptococci and coagulase negative staphylococci in allogeneic hematopoietic stem cell transplantation recipients: a prospective observational study.

Item does not contain fulltextAIM: This study was aimed to investigate whether any association could be found between the presence of an inflamed and infected periodontium (e.g., gingivitis and periodontitis) and the development of bacteremia during neutropenia following allogeneic hematopoietic stem cell transplantation (HSCT). METHODS: Eighteen patients underwent a periodontal examination before HSCT. Patients were classified as periodontally healthy [all periodontal pocket depths (PPD) /= 4 mm and BOP > 10%]. Oral mucositis (OM) was scored using the daily mucositis score. Blood cultures were taken at least twice weekly. RESULTS: Five patients were periodontally healthy, while 13 patients had gingivitis or periodontitis. Twelve patients (67%) developed bacteremia during neutropenia, of which 11 patients (61%) had one or more episodes of bacteremia due to coagulase-negative staphylococci (CONS, most often Staphylococcus epidermidis) or to oral viridans streptococci (OVS), or both. Patients with gingivitis/periodontitis more often had bacteremia than those with a healthy periodontium (p = 0.047), and BOP was associated with bacteremia (p = 0.049). All patients developed ulcerative OM, but its severity and duration were not associated with bacteremia. OM duration and the length of stay in the hospital were strongly correlated (R = 0.835, p </= 0.001). CONCLUSION: This study indicates that periodontal infections may contribute to the risk of developing OVS and CONS bacteremia during neutropenia following HSCT. While our results point to the importance of periodontal evaluation and management before HSCT, further studies on periodontal contribution to systemic infectious complications are warranted.1 juni 201
