Zoledronic acid and denosumab are two antiresorptive drugs currently in use for treating osteoporosis. They have different mechanisms of action, but both have been shown to delay the onset of skeletal-related events in patients with advanced cancer. However, medication-related osteonecrosis of the jaw (MRONJ) has been reported in cancer patients treated with zoledronic acid or denosumab. We studied 155 patients with several types of advanced cancer who were treated with zoledronic acid or denosumab in our hospital during the period from April 2010 through March 2013. Thirteen of these 155 patients (8.4%) developed MRONJ. MRONJ development was significantly associated with the number of zoledronic acid or denosumab infusions (p<0.001) and the duration of zoledronic acid or denosumab therapy (p<0.001). Logistic regression analysis showed that diabetes [odds ratio (OR)=6.699, 95% confidence interval (CI), 1.435–31.277, p=0.016], anemia [OR=14.559, 95% CI, 2.161–98.069, p=0.006], and pus discharge [OR=6.491, 95% CI, 1.514–27.835, p=0.012] significantly increased the risk of developing MRONJ. However, the risk of MRONJ was significantly lower [OR=0.137, 95% CI, 0.020–0.944, p=0.043] when patients received periodical dentistry maintenance. Diabetes, anemia, and pus discharge may also play roles in its development. These findings suggest that the active inclusion of dentistry maintenance in bisphosphonate or denosumab treatment of cancer patients can reduce MRONJ development.

The detection of infective endocarditis (IE) of oral origin has been previously discussed. However, there are few reports confirming this infection using molecular biological techniques. We herein describe the case of a 67-year-old man who developed IE. Blood culture samples and strains obtained from the gingival and buccal mucosa showed 100% identity to Enterococcus faecalis JCM 5803 on sequencing of 16S rRNA gene fragments. A random amplification of polymorphic DNA (RAPD) analysis showed the same pattern for these samples, thus confirming the identity of E. faecalis isolates in the blood and oral mucosa. Our observations provide novel information regarding the level of identity between IE pathogens and oral bacteria.
