JOURNAL FREE ACCESSThis study investigated the importance of retaining a large number of teeth after reaching old age. The authors analyzed data compiled in 2012 by Numazu City using the "Numazu City Basic Checklist for Nursing Care Prevention" targeting residents aged 65 years or older. Data from 25,943 subjects (12,007 males and 13,936 females) were analyzed to evaluate the association between the number of remaining teeth of the elderly residents and their responses to a basic health checklist. The checklist included 25 items (divided into seven sections) from a checklist created by the Japanese Ministry of Health, Labour and Welfare and items regarding the respondents' sex, age and number of remaining teeth (0, 1-9, 10-19, or ≥20). Collected data were analyzed by analysis of variance followed by multiple comparisons to evaluate the differences in age and category-specific scores for the seven other sections by the number of remaining teeth. After stratification of the respondents into 5-year age cohorts to remove age as a possible confounding factor, the association between the number of remaining teeth and the mean category-specific scores in each category was analyzed.
Furthermore, multiple regression analysis (forced entry method) was conducted, and the impact of the age and remaining number of teeth on health was analyzed. As a result, the mean score in each category increased with a decrease in the number of remaining teeth. Following stratification by age, similar results were observed; however, differences in mean scores were smaller in some categories. The results of the multiple regression analysis revealed that the adjusted coefficient of determination of motor organs was the highest; however, the level of 0.13 indicated that it explained the model to a smaller degree.
The standardized partial regression coefficient indicated that age had the most marked influence on health; however, there were some categories for which the remaining number of teeth had the greatest influence.
These results suggest that among aspects of lifestyle and health functions that can be ascertained from a basic checklist, age has the primary effect on health, followed by the number of remaining teeth.View full abstractDownload PDF (537K) -

JOURNAL FREE ACCESSObjective: To develop a locus of control scale for oral health behavior (LOCOH) that could be used to evaluate changes in both patients' behavior and consciousness regarding oral health, and to examine its reliability and validity.
Method: First, an original scale comprising 38 items was designed and applied to 185 students. Next, by item analysis, we developed an original LOCOH comprising 16 items. The LOCOH score of each student was evaluated on the basis of the sum of all scores. The relationship between the LOCOH score and observed values on the self-efficacy scale for oral health was examined using Spearman's rank correlation coefficient.
Results: As a result of factor analysis, two factors were extracted: "external control for oral health" and "internal control for oral health". High-level reliability of the LOCOH was verified through sufficient internal consistency (Cronbach's α=0.77-0.83). The LOCOH score showed a significant correlation with the generalized locus of control, suggesting its validity. The self-efficacy scales showed significant correlations with total, internal, and external scales of the LOCOH.
Conclusion: High-level reliability and validity of the LOCOH indicate that it may be useful for the prediction and improvement of oral health behavior.View full abstractDownload PDF (167K) -

JOURNAL FREE ACCESSAs dialysis patients are predisposed to various oral health problems, preventive dental care should be considered very important for this population. The aim of this study was to investigate the status of collaborative relationships between dialysis facilities without a dental department and dental facilities, with the purpose of quantifying and promoting preventive dental visits for dialysis patients. We statistically analyzed data from a nationwide survey of 1,142 dialysis facilities without a dental department, under the descriptive terms: "having a registered collaborative dental clinic," "having an ordinal collaborative relationship with a dental facility," and "further prospect of a collaborative relationship with a dental facility," according to the facility size. Additionally, the support for measures to promote dental visits among dialysis patients was analyzed. Significant differences between "having a registered collaborative dental clinic" and "having an ordinal collaborative relationship with a dental facility" were detected for all facility sizes (p<0.01, chi-square test). Regarding measures to promote dental visits for dialysis patients, "educational activities for medical staff at dialysis facilities" and "strengthening the collaboration between medical and dental facilities" had the highest support. Furthermore, "strengthening the collaboration between medical and dental facilities" was highly supported by facilities with an ordinal collaborative relationship with a dental facility in comparison with those lacking such a collaborative relationship (p<0.01, Mann-Whitney U test). It is suggested that having a registered collaborative dental clinic might be a first step toward promoting a collaborative relationship between medical and dental facilities. Regarding dialysis facilities and collaborative dental facilities, routinely strengthening the collaboration between medical and dental facilities might be an effective measure to promote preventive dental visits for dialysis patients.View full abstractDownload PDF (842K) -

JOURNAL FREE ACCESSTo prevent lifestyle-related diseases, it is recommended that people undergo more regular screening for them, receive relevant information, and be given appropriate medical referrals. We consider that these activities performed in the field of clinical dentistry would provide benefits from the perspective of public health. The aim of this study was to survey the prevalence of subclinical lifestyle-related diseases using a simple blood test for patients in the maintenance phase of periodontal treatment. The possible contribution of such an activity is discussed. A total of 63 patients (22 men, 41 women, mean age: 65.9 ± 6.7 years old) in the maintenance phase of periodontal treatment were monitored at the Department of Preventive Dentistry, Okayama University Hospital from January to July 2014. All subjects completed a self-administered questionnaire. Blood samples were obtained from the fingertip to judge the presence of subclinical liver disease, hyperlipidemia (dyslipidemia), renal disease, gout, pre-diabetes, and diabetes. Some patients reported an extensive medical history, including liver disease (3 patients), hyperlipidemia (14 patients), renal disease (2 patients), gout (1 patient), and diabetes (3 patients), and they were excluded from analysis related to each lifestyle disease. As a result, the prevalence of subclinical liver disease, hyperlipidemia, renal disease, gout, pre-diabetes, and diabetes were 16.7, 34.7, 16.4, 1.6, 46.7, and 6.7%, respectively. Thus, the field of clinical dentistry could contribute to the prevention of lifestylerelated diseases through screening examination and subsequent processes, including suggestions to visit appropriate medical institutions.View full abstractDownload PDF (344K)

JOURNAL FREE ACCESSIn the Dental Practitioners Act, improvement of public health is started as the role of dentists. Lectures on preventive dentistry and oral hygiene are the main components of public health education in dentistry.
Additionally, in spite of a decline in dental caries, they are still prevalent, and there are marked health inequalities on comparing dental caries to other diseases. Recently, the use of fluoride for caries prevention has been started as a part of national policies and ordinances of local governments. Therefore, dentists are required to have sufficient knowledge of fluoride application. To nurture such dentists, education on fluoride application as part of the undergraduate curriculum is crucial. To understand education on preventive dentistry, oral hygiene, and fluoride application in each dental school, the Commission on Fluoride Use of the Japanese Society for Oral Health conducted a survey in 1998. Following this survey, we conducted a second survey in September 2011. The survey revealed large differences in time for education on preventive dentistry and oral hygiene among colleges. The differences between colleges with the shortest and longest education times were as follows; in lectures: 8,340 minutes, in basic practice: 2,580 minutes, and in clinical practice: 5,400 minutes. There were also large differences in time for education on fluoride application among colleges: in lectures: 540 minutes, in basic practice: 280 minutes,and in clinical practice: 540 minutes. Several colleges did not offer clinical practice for fluoride application. Furthermore, compared to the results in 1998, time for education on preventive dentistry, oral hygiene, and fluoride application was markedly reduced. Education times reduced by 1,319 minutes in clinical practice for preventive dentistry and oral hygiene. In addition, only a small number of colleges provided education on covering unscientifically based opposition to fluoride application. Increasing the time for education and curriculum content on preventive dentistry, oral hygiene, and fluoride application for undergraduate dental students is needed.View full abstractDownload PDF (483K)
