The purpose of this study was to introduce a new in vitro method for evaluating the antimicrobial activity of toothpaste, reflecting the actual toothbrushing time and the dilution of toothpaste by salivation. We designed three experimental groups and one negative control group. The experimental groups were (1) 90 μL of toothpaste + 10 μL 1X phosphate-buffered saline (PBS, 9/10 dilution group), (2) 50 μL of toothpaste + 40 μL 1X PBS (1/2 dilution group), and (3) 25 μL of toothpaste + 65 μL 1X PBS (1/4 dilution group). During toothbrushing, saliva is continuously secreted into the oral cavity and the toothpaste concentration is diluted over time during toothbrushing. Therefore, the 1/2 and 1/4 dilution experimental groups were added. The negative control group was toothpaste diluted 20,000-fold with 1X PBS. Miracle Fresh Doctor toothpaste and Streptococcus mitis KCOM 1350, Prevotella intermedia KCOM 1107, Fusobacterium nucleatum subsp. polymorphum KCOM 1322, and Aggregatibacter actinomycetemcomitans KCOM 1306 were used as the toothpaste and target bacterial strains, respectively. The number of bacterial cells plated on agar plates in the negative control group was 1,000 CFU. If the number of colonies on the experimental group plate was less than one, the treatment was considered to have > 99.9% bactericidal activity. These results suggest that this new in vitro method for antimicrobial evaluation could be used as the standard method for testing the antimicrobial activity of toothpaste.

Objectives : The aims of the study were to examine perceived oral malodor and self-reported need for oral and dental care among patients receiving oral prophylaxis services and provide guidelines for developing educational programs(toothbrushing method and tongue cleaning) for oral hygiene and oral malodor prevention. Methods : The survey was administered to a sample of 462 receiving voluntary oral prophylaxis service in a dental laboratory at the J School of Public Health in Korea. The subjects were asked a range of questions related to the degrees of perceived oral malodor and concern for oral health status, as well as their demographic information and need for oral and dental treatment. Univariate analyses using Chi-square and T-test with a P-value of .05 were performed using SPSS Version 12.0 for Windows. Results : 1. Male participants reported "moderately concerned for bad breath and smell" and "I don't care bad breath and smell" 39.1% and 26.2% respectively, while more female participants were concerned for oral malodor. "moderately concerned for malodor" and" highly concerned for malodor" 41.1% and 28.5%(p<.05). a significant difference among age groups was found. 19% of young adults (less than or equal to 29 years of age) reported "highly concerned for bad breath and smell" while 36.4% of older adults (greater than or equal to 50 years of age) reported "highly concerned for bad breath and smell"(p<.05). 2. 12 non-smoking participants (3.7%) and 15 smoking participants (10.8%) reported that they have perceived bad breadth and smell (p<.05). 3. Smoking participants reported a higher degree of need for oral malodor treatment than that of non-smoking participants 88.5% and 82% respectively(p<.05). 4. The participants who did regular toothbrushing more than 3 times a day reported "no malodor", 77 % as compared to 66.7% of the participants who did regular toothbrushing 2 times a day. Toothbrushing 2 times a day reported either "moderate malodor" or "sever malodor"(p<.01). Participants with more frequent toothbrushing reported less oral and breath odor as compared participants with less frequent toothbrushing. Conclusions : The study suggested that there is a need to oral prophylaxis for prevention and toothbrushing and tongue cleaning method oral malodor care and oral health status.

Aims : The purpose of this study was to investigate whether there are any changes in taste sensitivity with advancing age and to see if smoking or oral hygiene can affect the taste sensitivity. Method : Nine hundred and thirty four subjects(458 male and 476 females) were included for the study and they were categorized into 4 age groups( under 20, 20 to 39, 40 to 59, and over 60 age group ). The electrical taste thresholds were measured using an electrogustometer for the 4 different sites in the oral cavity, I.e., tongue tip, tougue alteral, circumvallate papilla, and soft palate. Results : The elctrical taste thresholds were significantly incresed with advancing age in both gender, but the pattern of change is moere abrupt in female after 40. There were not significant differences in electrical taste threshold between smoking and non-smoking people. Taste thresholds were significantly lower in the groups with higher frequency of daily toothbrushing than the groups with lower frequency Conclusion : The electrical taste threshold is increased with aging. It is not influenced by smoking but by toothbrushing.

The purpose of this study was to identify the effect of providing toothbrushing by professionals as part of oral hygiene education for the elderly. We randomly visited 12 centers in the metropolitan city and analyzed the data of 114 participants among 310 early registrants aged >65 years, who participated in the study at all 3 time points. The subjects were categorized into an experimental group (odd-numbered visits) and a control group (even-numbered visits). Oral hygiene practices were provided for both experimental and control groups, but professional toothbrushing was performed in a different manner in the experimental group. Differences in plaque index (PI) according to the subjects' general characteristics and oral health status were assessed using the t-test, and the effect of PI difference between the experimental and control groups was assessed by repeated measure two-way analysis of variance. A stepwise multiple regression analysis was used to analyze factors affecting the PI. At baseline, the mean overall PI was 61.82. In both experimental and control groups, the PI significantly reduced from the baseline (p<0.01). At 5 weeks, the experimental group showed a decrease of 27.16 points from the baseline, and the 10-week PI was similar to the 5-week PI. The control group showed a decrease of 14.87 points from the baseline, and the PI increased by 5.74 points at 10 weeks. PI-related factors were gender and self-xerostomia. The PI was lower in the female group and the group with self- xerostomia (p<0.01). It is important to select an appropriate method to educate elderly subjects on proper removal of dental plaque and to habituate correct behavior, which requires inclusion of a direct toothbrushing intervention by a specialist.

Objectives : The purpose of this study was to evaluate the effects of incremental dental care(IDC) program on kindergarten children. Methods : The subjects were 46 kindergarten children aged 6 who wished participation in IDC program during 5 weeks at oral health center in G-college from March to May, 2012. The data of subjects were examined into oral conditions such as toothbrushing method and frequency, modified O'leary plaque index and dental caries activity before and after IDC program. The collected data were analyzed by SPSS statistical package version 19.0. Results : 1. The rolling and fones methods of toothbrushing increased from 10.8% to 91.3% after IDC program(p<.001). The change of toothbrushing frequency showed that over 3 times a day increased from 52.2% to 76.0% after IDC program(p<.01). 2. The modified O'leary plaque index of before toothbrushing education increased from 1st visit(score 32.19) to 5th visit(score 57.14) and after toothbrushing education increased from 1st visit(score 64.45) to 5th visit(score 78.27) during IDC program(p<.001). 3. As a results of dental caries activity test before and after IDC program, it was found that the bacterial numbers in S.mutans and Latobacillus reduced from 0.74, 0.70 to 0.28, 0.41 (p<.01) and the saliva buffering capacity increased from 1.50 to 2.02(p<.001). Conclusions : It is considered very necessary that IDC program should be maintained and extended to dental clinic so as to enhance the oral health state of kindergarten children.

Objectives : This study was carried out in order to contribute to preventing dental caries, which is the biggest disease in adolescence and to promoting oral health by implanting a right habit on oral care targeting adolescents, and further to offer basic help to proceeding with making the better health life. Methods : This study carried out questionnaire survey targeting 1,100 students of middle schools where are located in small and medium-sized cities of Gyeongnam from March 7-18, 2011. Statistical processing was performed frequency analysis and cross tabulation, by using SPSSWIN 12.0 program. Results : As for middle school students' oral health education experience, the group with educational experience was indicated to be 52.9% for girl students and 47.1% for boy students(p<.05) in case of gender. Toothbrushing time was indicated to be the highest with 25.6% in 'after having breakfast'. The appearance of toothbrushing after having lunch at school was indicated to be 53.3% for girl students and 26.3% for boy students(p<.001) by gender. The most important reason for toothbrushing accounted for 82.1% in the 1st grade, 71.1% in the 2nd grade, and 67.4% in the 3rd grade depending on school year as for the response as saying of 'aiming to prevent decayed tooth and gum disease.' Thus, the lower school year led to having indicated to be higher in response as saying of brushing teeth for preventing decayed tooth and gum disease(p<.001). As for a toothbrushing method by gender, boy students accounted for 24.2% in response as saying of 'brushing teeth freely', thereby having been indicated to be higher than 15.0% for girl students(p<.001). Conclusions : In order for toothbrushing method to be rightly practiced and habituated continuously, there will be a need of changing adolescents' awareness and of being driven systematically and continuously through oral health education. School oral health education, which can nurture right attitude and habit of oral health care, is thought to be necessarily expanded and executed.

Objectives: The purpose of this study was to provide basic data for gingivitis management programs by dental hygienists by evaluating the effect of oral health education, oil pulling, and professional toothbrushing on gingivitis. Methods: A total of 38 subjects were divided into three groups: control group (12 subjects), experimental group 1 (13 subjects), and experimental group 2 (13 subjects). The control and experimental groups were instructed to brush using the rotating method. Distilled water was provided to the control group after training. Coconut oil was provided every morning for about 10 minutes. In the experimental group 2, a professional brushing method was used at each visit. Results: There were no significant differences in oral health among the three groups, and there was homology between patient hygiene performance (PHP) index (p=0.144) and bleeding rate (p=0.213). The PHP index showed a significant interaction between the group and measurement time. The control and experimental groups showed changes in the PHP index with time (F=3.711; p=0.013). The bleeding rate showed a significant interaction between the group and measurement period. The control and experimental groups showed changes in the bleeding rate with time (F=6.707; p<0.001). Conclusions: Oral health education, professional toothbrushing, and oil pulling specialists in oral care of gingivitis were effective in managing gingivitis. It is necessary to educate people on self-management methods for oral health promotion using gingivitis management programs by dental hygienists.

A total of nine oral health educators for 17 persons with developmental disabilities conducted oral health education once a week for four weeks. The oral health educators provided oral health knowledge education and individual toothbrushing teachings. The developmentally disabled people in their 20s and 30s conducted oral health education without a guardian. Ten people who completed all the four pieces of training had no significant improvement in the toothbrushing method and the recommended number of toothbrushing sessions a day, as well as a lack of growth in oral health knowledge. However, 58.8% of the individuals expressed satisfaction with the oral health education program, whereas, 52.9% expressed the desire for a re-education. Although the ratio of teachers to students was 1:2, and the oral health education conducted four times, it was insufficient to promote a successful oral health behavior or knowledge for people with developmental disabilities. Therefore, as a suggestion, oral health education for people with developmental disabilities ought to proceed with their guardians to promote the success of the training.
