Objective?In oral health care, a refusal action can cause difficulties, and tactile hypersensitivity (TH) may be a contributing factor. People with TH of the face and mouth clench their jaws. Despite numerous reports on TH among children with disabilities, reports on TH in the elderly who are under long-term care are scarce. The purpose of this study was to investigate TH among the elderly who are under long-term care.Methods?We selected 80 residents (8 men and 72 women; mean age: 91.1±6.2y) in a Tokyo nursing home and investigated the presence of TH in them. We also obtained patients' (1) basic information (sex, age, stage of long-term care needs (SCN), and the degree of independent living (IL)); (2) oral information (swallowing status, choking tendency, and intraoral residue); and (3) nutritional information (serum albumin (Alb) levels and body mass index (BMI)). We assessed the face (the forehead, cheek, and perioral area) and the intraoral environment (buccal mucosa, buccal cavity, and palate) as testing sites for TH, using the tester's palm and forefinger. We confirmed the presence of TH when the tested areas reacted partially or fully by shuddering. We classified the subjects into 2 groups based on the presence or absence of TH and analyzed our results using a chi-square test and Mann-Whitney U test. This investigation was approved by the Dentistry Ethics Screening Committee, Tokyo Medical and Dental University.Results?A total of 18 residents were diagnosed with TH (22.5%). Significant differences in SCN, IL, choking tendency, intraoral residue, swallowing status, serum Alb levels, and BMI (P<0.05) were reported between this group and the non-TH group.Conclusion?We demonstrated that residents with TH were in an advanced SCN and had a lower IL score and a decreased swallowing and nutritional status. Therefore, oral health care, promotion of nutritional status, and meal support are particularly important for the elderly with TH.
