  • This study aimed to find out the effects of oral health education between the experiment group and the control group upon motivating them using oral facial program in 56 subjects including 29 members in the experiment group and 26 in the test group. With the collected data, Wilcoxon signed rank test was performed to understand the difference before and after the program. OHBI in the experiment group showed significantly higher than the control group (p<0.05), mean values after the program with $9.57{\pm}1.44$ and $8.68{\pm}1.46$ points in the experiment group and the control group, respectively. Mean QHI score in the experiment group was $1.00{\pm}.14$ points after the program while that in the test group was $1.03{\pm}.23$, demonstrating lower in the experiment group but not statistically significant. Mean scores of program satisfaction level were $4.13{\pm}.17$ and $3.94{\pm}.22$ points in the experiment group and the control group, respectively, demonstrating statistically significant. Based on the study results, the effects of oral health education using orofacial program showed the differences between the groups in dental plaque index and oral health behavior index. It is worth to use the oral facial exercise program as a tool for improving the authoring function and oral hygiene.

  • Objectives: This study aimed to examine the effect of the Oral Health Education Program (OHEP) on the change in the children's brushing behavior and reduction in the dental plaque index (PI) and to identify changes in their parents' perception of oral health. Methods: The OHEP was applied 44 children recruited from two childcare centers. We conducted a self-reported survey of the parents at baseline and evaluated the oral conditions of the children at baseline and after 5 weeks. Their brushing behavior was assessed once a week during the OHEP intervention period and daily at home thereafter. We measured the PI after a 12-week follow-up and performed repeated measures analysis of varience. Results: The average PI score of children significantly decreased at week 5 as compared to the baseline (1.90±0.53, p<0.001), despite a substantial increase in week 12 (2.67±0.08, p<0.001). OHEP was effective in reducing the PI score and modifying their brushing behavior. Conclusions: OHEP effectively modified the brushing the behavior of the children. Therefore, it is necessary to develop and expand a systematic oral health education program to promote self-management of oral health in children.

  • This study was conducted to investigate the potential of Stewartia koreana as oral healthcare materials. The antibacterial activity of ethanol extracts from leaves and branches of S. koreana against oral bacteria was confirmed. The leaf and branch extracts (1 mg/disc) showed antibacterial activity against P. gingivalis only among several tested oral bacteria. The leaf extracts showed higher antibacterial activity, with values similar to those of chlorhexidine, which was used as a positive control. The MIC of the leaf extract against P. gingivalis was 0.4 mg/ml and showed bacteriostatic action. The inhibitory effects of the extract on biofilm formation and on gene expression related to biofilm formation by P. gingivalis were determined by biofilm biomass staining, scanning electron microscopy (SEM), and qRT-PCR analysis. The biofilm production rate and cell growth of P. gingivalis in the cultures treated with 0.2-2.0 mg/ml of S. koreana leaf extracts were significantly decreased in a concentration-dependent manner. The inhibitory effect on the formation of P. gingivalis biofilms at concentrations of 1 mg/ml was confirmed by SEM. The qRT-PCR analysis showed concentration-dependent suppression of the fimA and fimB gene expression associated with fimbriae formation in the cultures treated with 0.2-2.0 mg/ml S. koreana leaf extract. These results support the conclusion that S. koreana leaf extracts can be used as oral healthcare materials derived from natural materials, as demonstrated by the antibacterial action and inhibition of biofilm formation of P. gingivalis.

  • The purpose of this study was to examine the effects of the toothpick method, one of professional toothbrushing methods, on the prevention of periodontal diseases and the satisfaction level of patients with that. The subjects in this study were 33 patients who included 16 men and 17 women. After the toothpick method was applied to the selected patients from January 9 to February 28, 2008, the collected data were analyzed with SPSS (Statistical Package for the Social Science) 12.0 program. The findings of the study were as follows: First, the patients investigated showed a 0.71 reduction in PI than in the past. The index of bleeding upon probing stood at 5.12, which dropped from 8.09 in the beginning. Second, the patients gave a mean of 4.20 to the professional toothbrushing out of possible five points, which showed that they expressed satisfaction with that. Third, as for the relationship between general characteristics and satisfaction level, the women were more satisfied with that ($4.25{\pm}0.33$). By age group, those who were in their 60s and up found that more satisfactory ($4.31{\pm}0.30$). Fourth, as to changes in oral symptoms by gender, the largest number of the men and women considered their gums to become healthier after the professional toothbrushing was applied. The above-mentioned findings suggested that dental institutions should be equipped with well-educated oral health care personnels who are responsible for the periodontal health of patients, and the development of oral health promotion programs is urgently required as well.

  • The aim of this study was to suggest a convenient method of monitoring the gingival state through plaque detection. Quantitative Light-Induced Fluorescence-Digital (QLF-D), which can assess mature plaque, can be used to assess the oral hygiene status of individuals and to establish an adequate intervention plans for them. The subjects of the study participated in the clinical training at Department of Dental Hygiene, N University. The subjects completed questionnaires on general characteristics and oral hygiene methods. Then, photographs of maxillary and mandibular anterior teeth of the subjects were taken using the QLF-D. After the oral examinations, gingival state was recorded according to the $L{\ddot{o}}e$ & Silness's Gingival Index (GI). In addition, a plaque control record was calculated in percentage using disclosing agent. The analysis of the relation between the plaque control record and the QLF-D scores showed positive correlation (r=0.638, p<0.001), and the analysis of the relation between the QLF-D scores and the gingival bleeding index scores also showed positive correlation (r=0.562, p<0.001). Besides, the study classified the participants into healthy gingiva group and the gingivitis group according to the classification criteria of GI, and when the difference of QLF-D scores between the groups was analyzed, the QLF-D scores were statistically significantly higher (t=-2.785, p=0.007) in the gingivitis group ($1.71{\pm}1.545$) than the healthy gingiva group ($0.74{\pm}1.290$). When the differences in mean values of the QLF-D scores were analyzed against and the gingival bleeding index scores, the QLF-D scores of 0 and 1 belonged to the category of normal gingival state while the QLF-D scores of 2, 3 and 4 belonged to the category of gingivitis state. Therefore, it is deemed that the red fluorescence detected by the QLF-D from the mature supragingival plaque can be used for monitoring the state of gingivitis.
