Objectives：The association of directorsʼ or office managersʼ interest in oral health management with the levying of additional fees for oral care in long-term care facilities was examined.

　Methods：We sent self-administered questionnaires to 1,806 long-term care facilities. As a proxy of implementation of oral care, the presence of an additional fee in public insurance for oral care in long-term care facilities was used as the dependent variable. Directorsʼ or office managersʼ interest in oral health management was used as the independent variable. Number of residents, nursing care level, dentistry services offered, presence of a dental professional, presence of an oral care manual, participation and enforcement of training on oral care, dental examinations, and access to dental care were entered as covariates. Poisson regression was used to estimate the prevalence ratio（PR）and 95％ confidence interval（95％CI）.

　Results：Respectively 67.4％ and 67.7％ of the facilities obtained an additional fee for oral care when the director or office manager had an interest in oral health management. The multivariate adjusted PR for directorsʼ and managersʼ interest in oral health management when an additional fee was levied for oral care were 1.32（95％CI：1.07～1.63）and 1.29（95％CI：1.08～1.53）, respectively.

　Conclusion：Our results demonstrated that, in facilities that offered dentistry services, employed a dental hygienist, and conducted regular dental checkups, an additional fee was levied for dental services when the facility director or office manager had an interest in oral health management. Directorsʼ or office managersʼ understanding of the importance of oral health management seems to be especially important for levying an additional fee for oral care in long-term care facilities.

　The purpose of this study was to evaluate the reliability and validity of an application for evaluating oral diadochokinesis（ODK）using a tablet-type device for community oral health activities such as late-stage dental examination for the elderly.

　The application recorded and evaluated the number of ODK /pa/, /ta/, or /ka/ by either the internal or external microphone of an iPad. In order to verify its validity, we compared the ODKs of the elderly obtained by the application with those collected by an IC voice recorder（IC method）.

　The average number of each ODK in 10 repeat measurements by the developed application was within ±1 time. The intraclass correlation coefficients（ICCs）of the ODKs between the application with internal microphone and the IC method were 0.68 for /pa/, 0.79 for /ta/ and 0.85 for /ka/, respectively（p＜0.001）. Furthermore, higher ICCs were obtained between the ODKs of the iPad with external microphone and those of the IC method, 0.86 /pa/, 0.92 /ta/, and 0.86 /ka/, respectively（p＜0.001）. Our results suggest that the developed application for evaluating ODK has sufficient reliability and validity for elderly oral health activities such as group health examination.
