ObjectiveWe examined whether general dentists can contribute to the detection of patients with undiagnosed diabetes and prediabetes by monitoring blood glucose in dental clinics.Research design and methodsA total of 716 patients who visited clinics for dental treatment were enrolled and classified into 3 groups (mild, moderate, and severe) according to Kornman's criteria for periodontitis. The correlations between the casual blood glucose level, presence or absence of the history of diabetes, and/or severity of periodontitis were evaluated.Results68 patients (9.5%) had hyperglycemia (blood glucose ≥200 mg/dL). Of these patients, 20 (29.4%) did not have a history of diabetes. Blood glucose tended to be higher with greater periodontitis severity. Of the 3 groups, the severe periodontitis group had the highest proportion of patients with hyperglycemia (p<0.0001).ConclusionsPatients with dental problems could be screened for diabetes, especially undiagnosed diabetes. General dentists could function as practitioners to screen for diabetes.Trial registration numberUMIN-CTR 000014877.

Orocutaneous fistulas are one of the most problematic postoperative complications after oral cancer surgery. Notably, in patients with mandibular plate exposure it is necessary to remove the plate. However, it takes longer for these patients to achieve complete fistula closure. The present report described an 84-year-old man with a postoperative orocutaneous fistula and exposed mandibular plate who was treated with the vacuum-assisted closure system. This system protects the wound from contamination while the negative pressure prevents tissue fluid retention, promotes blood flow, facilitates granulation tissue formation and decreases the bacterial cell count. Vacuum-assisted closure was successful in the present case, and complete fistula closure took 20 days. Additionally, there was no evidence of recurrence over the 11-month follow-up.
