並列タイトル等高齢者における口唇閉鎖訓練，もしくは音波ブラシによる唾液流量への影響
一般注記Aim and Background: Oral dryness causes various problems such as difficulty in swallowing and speaking. It also causes oral bacterial imbalance and increases risk of caries. Therefore, it is important to examine the effect of stimulation of the saliva flow by devices in an aged population with complaint of oral dryness sensation. The aim of this study was to improve and maintain the saliva flow and the oral wetness in Japanese elderly patients by facial mimetic muscle training using the lip trainer device or by using the sonic electric tooth brushing. Methods: Twenty-six patients were referred to the Department of Periodontology, Matsumoto Dental University Hospital, with complaints of oral dryness were enrolled in this study. All the patients had 20 or more teeth and were aged 60 years and above. They were randomly divided into two groups of 13 subjects each. In group P, subjects used the Patakara® lip trainer for 3 minutes, 3 times per day for 6 months. In group S, subjects used the Sonicare® sonic toothbrush for 2 minutes, 3 times per day for 6 months. Unstimulated and stimulated salivary flow rates, oral wettability and lip closing force were measured at baseline, and after 1 and 6 months. Clinical periodontal parameters: probing depth (PD), clinical attachment level (CAL) and bleeding on probing (BOP) were checked at baseline and 6 months. Results: Both of the groups showed increased timulated and unstimulated salivary flow rates, with group P showing better results than group S at 1 and 6 months. Group P also recorded better results for wettability than group S. Lip closing force was improved by facial muscle mimetic training at 1 and 6 months in group P. Conclusion: It is indicated that the salivary flow in the elderly Japanese
