Abstract Mandibular cortical erosion detected on dental panoramic radiographs is associated with increased risk of osteoporosis in older adults. Additionally, many reports have demonstrated an association between decreased number of teeth present and osteoporosis. However, whether mandibular cortical erosion is associated with a decreased number of teeth remains unclear. The purpose of this study, therefore, was to clarify the association between mandibular cortical erosion and number of teeth present in Japanese men and women aged 40 years and older. Among patients who visited our university hospital and underwent dental panoramic radiography for the diagnosis of dental diseases, 839 patients (293 men and 546 women) aged 40e89 years (mean [SD], 63.7 [10.6] years) participated in this study. Multiple regression analysis revealed that mildly to moderately eroded cortex (p ¼ 0.007) and severe eroded cortex (p < 0.001) were significantly associated with a decreased number of teeth present. Analysis of covariance adjusted for covariates revealed a significant association between mandibular cortical erosion category and number of teeth present (p < 0.001). Subjects with a severely eroded cortex had significantly fewer teeth present than those with a normal cortex (mean [SE], 20.7 [0.5] vs. 23.4 [0.3], p < 0.001) or mildly to moderately eroded cortex (22.2 [0.4], p ¼ 0.04). Subjects with a mildly to moderately eroded cortex had significantly fewer teeth present than those with a normal cortex (p ¼ 0.033). Our results suggest the significant association between mandibular cortical erosion and number of teeth present in Japanese men and women aged 40 years and older.

Background: Foot ulcers are costly complication among diabetes patients. These patients have an increased risk of amputation and increased mortality rate. Early recognition of the high-risk foot and sufficient care will save legs and improve patients` quality of life. Figures of incidence of foot ulcers varies and there are only limited information in relation the change of incidence over time. The aim of this study was to estimate 5-year risk for diabetic foot ulcer (DFU), lower extremity amputation (LEA) and all cause of death. Methods: Retrospective cohort study including all subjects with diabetes enrolled in our diabetic outpatient clinic from beginning 2008 until middle 2014. Data were collected from clinical records. Results: 528 subjects with mean age of 61.3 (±13.8), 57.4% were male. The mean of HbA1c in diabetic patients at baseline were 8.1% +/- 1.9%. Cumulative incidence was 1.3% for DFU, 0.18% for LEA and 4.7% for all-cause of death. The prevalence of cardiovascular and cerebrovascular conditions, pneumonia were 2.3%, 1.9%, 2.3%, respectively. Cause of deaths was cancer (64%), pneumonia (20%), cardiovascular death (4%). Conclusions: Several factors may explain the incidence in diabetes-related LEAs. Diabetes prevention strategies and controlling risk factors are important in people with type 1 and 2 diabetes.
