Chronic kidney disease （CKD） is defined as persistent kidney damage, usually marked by albuminuria or a reduced glomerular filtration rate, which ultimately leads to end-stage kidney disease and a need for dialysis. CKD is a very common condition, with an estimated 13.3 million （12.9%） people affected by CKD in Japan. 　A potential bidirectional association between CKD and periodontal disease has been reported in recent studies. Individuals with periodontal disease exhibit endothelial dysfunction, which leads to atherosclerosis, hypertension, and CKD. Immune dysfunction and mineral bone disorder in CKD patients are suggested to be associated with development and progression of periodontal disease. 　Evidence of this association is accumulating through increasing numbers of well-designed cohort studies, and periodontal disease has been demonstrated to be a risk factor for CKD in older Japanese. However, only limited information about the impact of periodontal therapy on CKD patients exists. Because the prevalence of both diseases in Japan appears to be increasing, largely as a result of the aging population, further studies with Japanese participants are needed to elucidate this association.

Relationships among the health conditions, physical and mental conditions, nutritional conditions and activities of daily living, and conditions of denture wearing of elderly were assessed to determine the influence of denture wearing on the nutrient intake at multiple facilities. The total number of subjects was 12 outpatients with removable dentures in our clinic of Kyushu Dental University Hospital. The number of remaining teeth, occlusal support （Eichnerʼs classification）, condition of the defect area （Kennedyʼs classification）, ability to masticate based on the masticatory score on food intake, and solubility of glucose were measured as the dental conditions. OHIP-49, the physical component score （PCS）, and mental component score （MCS） based on the 36-item short-form health survey （SF-36）. Profile of mood states（POMS）, mini nutritional assessment （MNA）, body mass index （BMI）, and barthel index （BI） were also evaluated. All subjects were divided into three groups; Group A （remaining tooth exist in both upper and lower jaws）, Group B （remaining tooth exist in both upper or lower jaws）, Group C （edentulous in both upper or lower jaws）. 　It was found that the more number of the remaining teeth increased, the more chewing ability increased significantly.

Suppurative arthritis of the temporomandibular joint is comparatively rare because temporomandibular joint is strong anatomical structures in infection defense. We report a rare case of acute suppurative arthritis of the temporomandibular joint of a 76-year-old woman. Further, we reviewed the literature on acute suppurative arthritis of the temporomandibular joint of 29 cases of this disease in Japan.
