The purpose of this study was to evaluate the effect of professional tooth cleaning and dental health education on dental clearances and dental health behaviors. This study was designed into two groups, 80 persons of control group for dental health education and 80 persons of experimental group for dental health education and professional tooth cleaning. In order to compare education effects, the researcher applied different educational methods. The parameters were the toothbrushing frequency, the average tooth brushing time, the action rate of toothbrushing after lunch, and the rate of using oral hygiene product. The data were analyzed and the following was the conclusion. The frequency of toothbrushing in two groups increased. Toothbrushing frequency of the experimental group was significantly higher than that of preliminary group and control group. The action rate of toothbrushing after lunch in two groups increased. But the experimental group was significantly higher. The score for dental clearances of the experimental group were higher than those of the control group. The data showed statistically significant difference.

This study aimed to arrive at reasonable and realistic prices for professional tooth cleaning (PTC) in order to expand its clinical utilization. The study involved 214 dental implant patients who received PTC. Cross-tabulation, one-way ANOVA, t-test, and stepwise multiple regression were performed for analysis. The mean satisfaction score was 4.60 points, and 92.5% of all subjects were willing to receive PTC consistently. The most common reason to receive PTC was a feeling of refreshment in 84.7%, and 84.1% were willing to pay for PTC. The mean willingness-to-pay price was 28,100 won, and the mode was 10,000 won. Willingness-to-pay price increased as average monthly income and satisfaction level for PTC were higher. The price also increased with age and was higher in women than men. Suggesting and settling reasonable and realistic prices for PTC are expected to be useful in maintaining the long-term health of the dental implant and reducing socio-economic costs.

Objectives: Smoking is related to periodontal disease and periodontal therapy. So the aim of this study was to investigate the effects of professional tooth cleaning and plaque control instruction (PT & PCI) for smoking behavior. Methods: A total of 151 adults were investigated using the O'Leary Plaque Index (PI), $L\ddot{o}e$ & Silness gingival index (GI) and the number of sextants possessing periodontal pocket (SPP). And adults were given a through dental scaling and Watanabe method for dental plaque control. Follow up examination were conducted after 3 months and compared the pre and post- status. The collected data were analyzed with t-test, paired t-test and one-way analysis of variance. Results: Regardless of smoking behavior, improving effects were identified after PT & PCI on PI, GI and SPP in the whole population. However, the effects of GI improvement were significant in the smoking group alone; those of PI improvement were most significant in the non-smoking group; and those of SPP improvement were more significant in non-smoking and pre-smoking groups than in the smoking group. The shorter period of smoking and the smaller amount of smoking, the greater effects of PT & PCI by smoking-related characteristics. Conclusion: Smoking cessation instruction should necessarily be included in oral health education in that smoking is an important factor to consider in prevention of periodontal diseases and periodontal therapies.

This study conducted a 'specialist tooth brushing' method against the severely disabled once every other week. The purpose of this study is to analyze and validate the effectiveness of maintaining healthy periodontal management when consistent oral hygiene lasts with minimum stimuli for 24 - months. The conclusions were as follows. Table 2 compares the difference between group 1 and 2 from the 1^st to 11th management and verifies the actual difference in measurement of each index. Group 1 used a professional tooth brush while Group 2 used a general brush. There were found many significant differences in dental index. As for PHP, Oral Malodor index and gingival bleeding, it was found that one or two times of dental care can make substantial differences in dental health condition. These results show that as the number of toothbrush method has been increased, gingival bleeding and periodontal index are significantly improved, not to mention the improvement of gingivitis and periodontal disease. This is because periodontal tissue is affected by brushing method, brushing time and consistency of dental care. During the 6-month period, 20 minutes of active periodontal care was intensively conducted, and for 18-months the effect of consistent care was verified by 10-minute periodontal care once every other week. As a result of the test, it was found that there was no complete regression in the basic periodontal treatment and the periodontal health condition had been maintained for 24 months. Also this test shows that, despite of inconsistent dental hygienic care, regular plague control can prevent dental diseases and maintain the dental health. This study proved that periodontal condition can be maintained by periodontal care once every other week as the tooth brushing properly stimulates the gums with positive effect. Therefore, professional dental healthcareworkers should be designated for each facility for the disabled, and dental health of the disabled should be professionally cared on a regular basis, and consistent and repetitive management by the dental care specialist are required.

Background: This study aimed to investigate the changes of the amount of P. gingivalis in saliva by professional preventive treatment of periodontal disease by dental hygienists. Methods: A total of 109 subjects participated in this study with informed consent. The control group (38 subjects) performed oral hygiene management individually. The periodontal treatment group (35 subjects) underwent root planning once every 3 weeks for a total of 4 times. The professional periodontal prevention group (36 subjects) underwent interdental cleaning and professional tooth brushing once every 3 weeks for a total of 4 times. Paired T test and analysis of variance were performed to compare the difference among the groups in the amount of P. gingivalis. Results: The copies of P. gingivalis in the professional periodontal prevention group decreased from 773.62±1,198.09 to 241.40±430.40 after treatment significantly. The control group decreased from 525.22±582.54 to 244.29±385.88 after treatment. The periodontal treatment group showed insignificant change of P. gingivalis. Conclusions: This study showed the professional periodontal prevention was more effective than periodontal treatment in decrease of P. gingivalis.

Gingivitis is the most prevalent type of periodontal disease and the dental plaque is considered as a major contributory factor. As the poor oral hygiene is firmly related to the occurrence of periodontal disease, pediatric dentist should make every effort to promote the oral health and control the plaque effectively for the high risk patients, especially for those who are under orthodontic treatment. P.M.T.C.(Professional Mechanical Tooth Cleaning), introduced by Dr. P. Axelsson in 1969, is a very effective method of plaque removal and can be performed by specially trained personnel. Two pediatric orthodontic patients were treated by P.M.T.C. for the elimination of gingivitis and gingival swelling. Signi ficant improvements of gingival condition were achieved in both cases but additional preventive programs and home care along with professional office care seem to be necessary for the best result.

The purpose of this study was determine the effects of professional tooth cleaning and plaque control instruction(PT & PCI) on reduction of peri-implantitis. A total 80 implant patients were investigated using O'Leary plague index(PI), L${\ddot{o}}$e & Silness gingival index(GI), implant bone loss(BL). While the PT & PCI was conducted by using 'Watanabe method' after scaling for the experimental group, the engine polishing and a plaque control instruction was operated by rolling method after scaling for the control group. The collected data were analyzed with t-test, ANOVA, paired t-test and stepwise multiple regression. PI and GI of the experimental group significantly decreased than the control group(p<0.05). BL, also tended to decreased in the experimental group than the control group(p=0.155). Multiple regression analysis, the factors that was highly correlated with PT & PCI on the PI and GI. According to the implant characteristics, implant location and duration were closely related to PI(p<0.05). Therefore, the PT & PCI is one of the effective methods to reduce the failure caused by the peri-implantitis. Based on this conclusion, that it would be meaningful if the proposed PT & PCI is applied to the oral health management programs of the implant patients.

This study was conducted to investigate the optimal management interval in 33 healthy adults by observing changes in oral health on the basis of the plaque control index and gingival index. When plaque control score was compared according to the period, it was found that oral hygiene management was the best in the fourth visit (p<0.05). Improved oral hygiene status was observed during the 3- and 6-month follow-up (p<0.05). Regarding gingival index, the fourth visit showed the healthiest gingival status (p<0.05). At the 3-month follow-up, the gingival index worsened, but a healthy gingival status was attained by 6-month follow-up (p<0.05). The plaque control score according to interest in dental health showed that the 'interested' group had good oral hygiene management (p<0.05). As a motivation for oral hygiene status and gingival health, examination with a 'phase contrast microscope' in the first visit and calculation of the 'evaluation index' in the follow-up visit tended to improve the patients' ability for oral hygiene management (p>0.05). The questionnaire survey showed, that the optimal management interval was 1, 3, and 6 months. As a result, with the effective management interval for the preventive management program focused on professional mechanical tooth cleaning, which was administered weekly, the maximum ability for oral hygiene management was attained at the fourth visit. The effective management period was 1 month. The use of a phase contrast microscope and the calculation of the evaluation index for oral hygiene management could influence the motivation to improve oral hygiene management.

Black staining of the teeth in children and adolescents does not cause pain or serious illness, but it can be socially debilitating for esthetic reasons. Black staining is easily removed through periodic professional mechanical tooth cleaning and ultrasonic scaling, but it can easily recur within few months. Using essential oil-containing mouth rinses diluted at 50% twice per day could prevent the black staining from returning after it is removed, reducing the need for mechanical treatments and improving esthetics.
