The purpose of this study was to use basic data of dental hygiene curriculum by comparing the rolling method and modified stillman method. Plaque measurement method, Q-ray examination of the clinical utilization value shall review. True experimental design is randomized controlled trial to the intervention group and the control group. Measurements are plaque control record (PCR; O'Leary index) measurements and Quantitative Light induced fluorescnece Digital (QLFD) shooting as a pre-test was conducted. Intervention group is modified stillman method, control group is rolling method. Intervention after 5 weeks, PCR measurement and QLFD shooting was carried out as a post-test. Rolling method and modified stillman method plaque reduction did not differ. Intervention before and after the results of the comparison showed reduced plaque score after brushing law education. Also, Plaque reduction differences were more pronounced modified stillman method than rolling method. PCR and QLFD values of the correlation was not confirmed but SPS Score and the lower value of the ${\Delta}R$ value of the correlation. Plaque of maturity tooth that are not observed visually.

The purpose of this study was to examine the oral health behavior and awareness of teachers in community children's centers, the state of oral health care among children in the centers and the opinions of the teachers on child oral health education in a bid to gather information required for the development of oral health education programs geared toward community children's center teachers. The subjects in this study were 178 teachers who worked in 98 community children's centers in the city of Incheon. After a survey was conducted from April 28 to June 4, 2010, the collected data were analyzed. The findings of the study were as follows: The 57.3% of the teachers investigated provided toothbrushing guidance from time to time or couldn't do it at all. As for the reason why toothbrushing guidance was scarcely conducted, the largest group cited shortage of sinks(27.5%) as the reason, and the second biggest group replied they couldn't afford to pay attention to that due to heavy workload(20.6%). The third greatest group was pressed for time(16.7%). The teachers got a mean of 3.27 in oral health behavior, and 87.7% were concerned about children's oral health. The group of teachers who ever received oral health education was significantly better at oral health behavior and showed significant more interest in oral health(p<0.01). The 97.2% of the respondents considered oral health important. Concerning the reason, they replied it was crucial for systemic health (74.2%). The 89.4% of the teachers viewed child oral health education as necessary, and 86.5% had an intention to provide oral health education for children. They hoped to receive education on the oral health control act(4.52) and the prevention of dental caries(4.40). The above-mentioned findings confirmed that in order to step up the oral health promotion of child users of local children's centers, it's necessary to provide secondhand education for them through their teachers who have a great impact on them. Therefore the development of oral health education programs that cater to local children's center teachers is required.

The purpose of this study is to work out plans to reduce oral malodor by carrying out effective methods. In the research, 17 volunteers were selected from the students at Sahmyook Health University's Dental Hygiene Dept. in order to measure the effects of reduction of oral malodor. The results are as follows. 1. As time passes, both the control group and the experimental group proved the effects of the reduction of oral malodor for 20 minutes after the experiment(p<0.05). 2. The experimental group with tooth-brushing showed a statistically significant difference compared with the control group from a lapse of 5 minutes after the experiment to 20 minutes(p<0.05). 3. The experimental group with tongue cleaner did not prove a statistically significant difference compared with the experimental group with toothbrushing( p>0.05). 4. The experimental group in which participants took a candy showed a statistically significant difference compared with the control group after 5 minutes(p<0.05). 5. The experimental group with chewing a gum proved a statistically significant difference compared with the control group for 10 minutes(p<0.05). Using a washing implement of the tongue, taking a candy, and chewing a gum proved the same effect of reducing foul breath as in the case of operating a tooth-brushing. This experiment proves that taking a candy or extending time of chewing a gum was effective in a short time, and using a tongue cleaner or chewing a gum for 5 minutes was a useful method for reducing oral malodor if not operating a tooth-brushing.
