Abstract
In recent years, emphasis has been placed not only on collaboration between medicine and dentistry but also on collaboration among multiple professions. In team medicine, dentistry is expected to provide general dental care and supportive care to prevent the onset or worsening of oral adverse events in sick and perioperative patients. We have been studying oral management strategies to reduce the number of bacteria in saliva after surgery to prevent postoperative infections in the perioperative period. The study suggested that postoperative feeding status is a factor that influences the postoperative salivary bacterial count. This suggests that it is desirable to modify oral care methods according to the postoperative feeding status. Another topic of importance for collaboration with the medical community is Medication-Related Osteonecrosis of the Jaw (MRONJ), which is a side effect of drug therapy for osteoporosis. However, there are currently no guidelines for MRONJ. The current practice is to treat patients who have been treated for osteoporosis or cancer, or who have a history of taking medications with side effects that put them at risk for developing MRONJ. The patient's oral examination and periodic panoramic radiographs are important to identify risks, maintain good oral hygiene, and eliminate sources of infection. In the stage 1 situation when MRONJ has developed and there is no pain, efforts should be made to maintain oral hygiene, including intraoral examination, panoramic radiographs, and brushing of the exposed areas with a disinfectant to prevent deterioration. In Stage 2 or later, patients may experience pain, and it is necessary to develop a treatment plan with a surgery view.
