JOURNAL FREE ACCESSTo develop a health promotion program to prevent periodontal disease in a community, the PRECEDE-PROCEED model was used to guide the planning and its availability was assessed. Yasuura-cho, a rural town in Hiroshima Prefecture, participated in the program in 1999. The population of the town is 13,400 and there are 3 private dental offices. A steering committee was formed by community members, public health nurses, dentists and dental hygienists in the town. The members of the steering committee agreed that the goal of the program was to increase the ratio of adults without subjective symptoms of periodontal disease from 18 to 55% within two years. In order to obtain data for assessment, questionnaires and focus group interviews were performed. According to the behavioral and environmental assessment, regular dental check-up and utilization of dental floss were selected as behavioral targets. For the educational and ecological assessment, the following three categories of factors affecting dental check-up and individual utilization of dental floss were identified : predisposing factors : people know that periodontal disease can be prevented by dental check-up and flossing, reinforcing factors ' people are satisfied by receiving scaling at the dental office, and feel refreshed after using dental floss I and enabling factors : there are baby sitters at the dental office, and people can learn how to use dental floss in the dental office. By the administrative and policy assessment, the health education program for prevention of periodontal disease of Yasuura-cho was established and implemented. It was suggested that the PRECEDE-PROCEED model would be a useful tool for planning a periodontal health program in a community.View full abstractDownload PDF (999K)

JOURNAL FREE ACCESSA health promotion program to prevent periodontal disease in a community was implemented and evaluated by the PRECEDE-PROCEED model. The program was started at Yasuura-cho, a rural town in Hiroshima Prefecture in 1999. The process assessment was performed at the end of 2000. To perform the impact assessment and outcome assessment, the same questionnaire used in 1999 was used in September 2002. According to the process assessment, the ratio satisfied by receiving tooth brushing instruction at the dentist's office increased (reinforcing factor). The ratio of these who used dental floss or an inter-dental brush also increased (enabling factor). According to the impact assessment, the ratio receiving regular dental check-ups increased from 14% to 22% for those in their thirties, and 12% to 25% in their fifties. The ratio of people who use dental floss increased from 32% to 42% for those in their thirties. Outcome assessment showed that the ratio who recognized bleeding after brushing teeth decreased for those in their thirties and fifties. It was suggested that the PRECEDE-PROCEED model would be a useful tool for planning, implementing and assessing the periodontal health program in a community.View full abstractDownload PDF (901K) -

JOURNAL FREE ACCESSAs an experiment related to measures to control bacterial contamination of the circulating water in dental units, we installed an EPIOS 02 residual chlorine correction disinfection system between a unit and a tap-water pipe. In part of the experimental group we replaced the tubing inside the unit's piping with fluororesin processed tubing, and we conducted experiments under a variety of conditions. As a result, no residual bacteria were detected in the circulating water in the experimental group, and morphological examination of the inner surface of the tube showed some morphological changes. These findings suggested that the EPIOS 02 residual chlorine correction disinfection system is useful for controlling contamination of the water circulating in dental units.View full abstractDownload PDF (1576K) -

JOURNAL FREE ACCESSOral diseases not only induce local pain and masticatory impairment but are also important factors with psychosocial and economical burden. In recent years, the importance of the QOL scale in evaluation of these aspects has been increasing. Therefore, to develop a comprehensive oral health-related QOL scale that well reflects psychosocial aspects and allows the addition of complementary items and combination with situations, we produced a Japanese version of the General Oral Health Assessment Index (GOHAI). After permission to produce a Japanese version was obtained from the original author, the GOHAI was translated into Japanese. Evaluation was performed by a focus group, and a tentative scale was produced. A pilot study was carried out using this tentative scale in local residents, and based on its results, the questionnaire was re-evaluated. Since long question sentences, difficult expressions, and the presence of opposite items were suggested as problems, the tentative scale was revised with care to follow the original as closely as possible. In addition, the layout and character form were evaluated, and a reverse translation was produced. The reverse translation was confirmed by the original author. With her final permission, the GOHAI Japanese version 1.0 was completed.View full abstractDownload PDF (695K) -

JOURNAL FREE ACCESSThe aim of this study was to test the causal relationships of the PRECEDE-PROCEED model in order to achieve a better understanding of the characteristics of the model. Guardians of 18-month-old children were asked to complete a questionnaire regarding to 7 oral health components on the basis of the PRECEDE-PROCEED model. The MIDORI model modifying the PRECEDE-PRO-CEED was tested by a linear structural relations program (LISREL), using data of 838 guardians who completed the questionnaire. The MIDORI model was found to be not necessarily consistent with the data (GFI = 0.91, AGFI = 0.77, RMSEA = 0.16). Neither dental health behavior nor environment had significant effects on oral health. LISREL diagnostic information (modification index and par change) and a reconsideration of the questionnaire items led us to allow 'predisposing factors' to effect 'oral health' and QOL, 'environment' to effect 'reinforcing factors', and 'enabling factors' to effect 'oral health'. With these changes, the overall fit of the revised model was judged to be satisfactory (GFI = 0.97, AGFI = 0.93, RMSEA = 0.08). The revised model showed that QOL would be improved by strengthening 'dental health behavior' and/or 'predisposing factors'. Health education without testing the model might not fit the reality of people's behavioral change.View full abstractDownload PDF (793K) -

JOURNAL FREE ACCESSThe aim of the present study was to investigate the relationship of dental factors for behavior change with the effects of an intervention program in the workplace and consciousness of the oral health of workers. Following completion of oral health examinations for 208 workers by dentists, dental hygienists provided oral hygiene instruction consisting of tooth brushing skills in marginal areas, use of inter-dental brushes and recommendation of periodic dental visits. To evaluate the effects of the oral health program, subjects were surveyed with questionnaires prior to and immediately after, one month after and one year after intervention. Subjects aware of the skills pertaining to tooth brushing in marginal areas increased significantly at one month (55%) and at one year (62%) after intervention in comparison with the baseline level (35%). Subjects employing an inter-dental brush increased significantly at one month (40%) after intervention compared with the baseline level (24%). However, the increase was not significant at one year after intervention (31%). 87% of subjects expressed willingness with respect to periodic dental visits immediately after intervention ; however, at one month after intervention, only 15% of respondents favored periodic dental visits. Logistic regression analysis revealed that confidence with respect to brushing in marginal areas was a significant independent predictor of both behavioral factors for tooth brushing in marginal areas and establishment of behavior change of the brushing method. Belief of caries prevention and awareness of refreshment realized through the use of an inter-dental brush and environment in terms of the ease of its acquisition were significant independent predictors of utilization of the inter-dental brush. These results indicated that factors and the extent to which they affected oral health behavior differed according to the objects of behavior. Furthermore, these findings suggested that expected behavior relating to oral health could be observed in the workplace by the selection of appropriate factors for each object of behavior.View full abstractDownload PDF (1141K) -

JOURNAL FREE ACCESSThe purpose of this study was to develop a new method for chemical stain control. The removal of acquired pellicle by an active agent and the mechanism of pellicle removal were examined. Hydroxyapatite (HA) discs mounted on a mouthpiece were held in the oral cavity of three healthy volunteers. The in situ pellicles, periodically formed, were dyed with phloxine, the avalues from the Commission Internationale de 1' Eclairage (CIE) L a b uniform color scale were measured with a spectrophotometer, and the amount of protein was determined by ninhydrin assay. Tea-denatured pellicles, formed with tea rinsing, were brushed with solutions containing chemical agents, and the residual pellicles were evaluated. HA powder was treated with diluted saliva solutions for two hours, then various amounts of pyrophosphates were added, and the amounts of adsorbed pyrophosphates and desorbed proteins were determined. The results showed that the a values correlated significantly with the total protein (r = 0.95, p<0.0l). The pellicles grew with time and reached a plateau after about two hours in three volunteers. The amount of residual pellicle (a value) in the sodium pyrophosphate group (Mean ± SD = 0.73 ± 0.35) was significantly lower than that in the control group (6.28 ± 0.28 ', p<0.01), and was the lowest produced by the agents tested. Scanning electron microscope (SEM) images of residual pellicles showed that pellicles were desorbed by brushing with the pyrophosphate solution, and were physically removed with a toothpaste slurry. The isotherm of pyrophosphates on HA was characteristic of Langmuir adsorption, and a linear relationship between adsorbed pyrophosphates and desorbed proteins was demonstrated. Consequently, pyrophosphate was found to be an effective agent for removal of pellicle. The pyrophosphate adsorbs to the HA surface and breaks the ionic bonds between the pellicle and HA. The potential of pyrophosphate as an agent for removal of stained pellicle was indicated by this study.View full abstractDownload PDF (1603K)

JOURNAL FREE ACCESSThe national standard of fluoride in drinking water provides for a maximum of 0.8 mg/l in Japan. Takarazuka City, however, has its own standard of a maximum of 0.4〜0.5 mg/l much lower than the national one, in order to reduce the number of moderately mottled and decayed teeth. The appropriateness of the standard is proved by the decline of the prevalence rate of moderately mottled teeth in school children who have consumed standard drinking water since birth. This time we examined the relation between the prevalence rate of mottled teeth in school children, released from the board of education in Takarazuka, and the fluoride concentration in drinking water, publicized by the bureau of water supply. Concerning the fluoride concentration in drinking water, our examination showed that the yearly average concentration between 1982 and 2000 never exceeded the city standard. Looking at the progress of the prevalence rate of mottled teeth in school children born between 1981 and 1988, 5.3% in 1996 reduced to 2.3% in 2000. Concerning the caries-free rate, on the other hand, the relation was not clear, although we recognized its gradual increase year by year. This is because a similar tendency can be seen nationwide. Based on these data, we judged that the city standard, a temporary standard for control, is appropriate because it has resulted in a reduction in the occurrence of moderate mottled teeth and raised the caries-free rate.View full abstractDownload PDF (1000K)
