Objectives : The purpose of this study was to investigate the possible differences in elementary schools jointed to fluoride mouth rinse plans in health centers. Methods : Students from the third to sixth grades filled out the questionnaires. Data were analyzed by the statistical package SPSS 12.0. Results : The rate of a personal toothbrush holding and toothbrushing after lunch were higher in those who rinsed their mouths with fluoride than those who did not.(p<0.05). Toothbrushing by the rolling method was more prevailing in the students who rinsed their mouths with fluoride(57.0%) and having regular dental checkup(p<0.05) than in those who did not(39.8%). Conclusions : The students who had rinsed their mouths with fluoride showed the good oral health behavior. Continuing good quality of oral health care education must be provided to the students by professional dental hygienists.
The use of mouth-rinses containing sodium fluoride after tooth brushing has been proposed as a potentially useful measure for the prevention of dental caries in the practice of public health. About 700 middle school girls rinsed their mouths in the school once a week with sodium fluoride sodution after tooth-brushing. Tooth brushing was practiced everyday after meals and the rinses were carried out under the supervision of the teachers. The procedure consisted of gargling 10cc of fluoride solution for one minute and immediately followed by a second rinse with tap water. The rinsing was started in May 1976 and continued for one year. The results were as follows: 1) The inhibition of the 'D' Person rate was 76.04%, 'M' person rate was 80.79%, 'F' person rate was 4.06% and, 'D.M.F.' person rate was 76.86%. 2) the reduction of the 'D.T.' Index was 81.94%, 'M.T.' Index was 85.71%, 'F.T.' Index was 7.69% and, 'D.M.F.T.' Index was 76.83%. 3) Mouth rinsing with 0.3% NaF solution and tooth brushing are of value in the mass control of dental caries.

Through out the world dental caries seems to be decreased as it is difficult to make an accurate diagnosis for dental caries. The traditional diagnostic method which is probing and x-ray taking has many limitations to diagnose the early caries, so there were recommendations for the needs of new equipments such as laser fluorescence(LF), digital imaging fiber-optic trans-illumination(DIFOTI), and quantitative light fluorescence (QLF) which were developed from various study results. Also confocal laser scanning microscopy(CLSM) and ultrasonics are used for research progression. This study is to evaluate whether it is possible to monitor accurately for remineralization amount of enamel surface early caries using DIFOTI or LF After inducing artificial caries to bovine teeth to 10 participants remineralization was enhanced by 0 ppm and 500 ppm fluoride mouth rinse solution for 3 weeks. Then they were cross sectioned and analyzed using gold standard of the lesion depth measured by CLSM. The following results were obtained: 1. The measured percentage of light intensity(luminosity ratio) by DIFOTI increased with remineralization period, and showed significant reverse correlation with lesion depth measured by CLSM (p<0.01). 2. The measurement of laser fluorescence increased with remineralization period, and showed significant correlation with lesion depth measured by CLSM (p<0.01). 3. To the result for CLSM, 500 ppm fluoride mouth rinse group showed rapid rate for decreased tendency of lesion depth than 0 ppm fluoride mouth rinse group. In conclusion DIFOTI system was used to measure accurately for the remineralization amount of early surface caries, it is a very useful equipment to detect precisely the changes for early enamel caries remineralization during treatments.
Objectives : The purpose of this study was to investigate cognition on oral health education and dental caries preventive effect in kindergartens and child care facilities. Methods : A self-reported questionnaire was completed by 260 teachers in kindergartens and nursery facility in Daejeon from January to February, 2013. Except incomplete answers, 248 questionnaires were analyzed by using the statistical package SPSS WIN 18.0.

Several alternatives for increasing the fluoride concentration in the mouth, such as water fluoridation, ingestion of fluoride supplements, fluoride paste, fluoride mouthrinse, application of fluoride gel are available. There is an impressive body of evidence that the topically deliverd fluorides are clinically effective in inhibiting the progression of dental caries. Recent studies on the cariostatic action of fluoride have indicated the importance of fluoride in the fluid environment of the teeth. The fluoride levels in unstimulated whole saliva can be considered indicative of F in the aqueous phase available for interaction with the tooth surface at a given time. The retention of F in the mouth after topical fluoride treatment is considered to be an important factor in the clinical efficacy of F. The aim of this study was to determine the elevation and clearance of fluoride in whole saliv after the following topical flouride treatments using HMDS-diffusion technique and fluoride ion electrode. The obtained results were as follow: 1. Average salivary fluoride concentration in the unstimulated whole saliva was $0.0152ppm{\pm}0.0091ppm$. Unstimulated salivary flow rate was between 0.34-0.36ml/min and there was no statistically significant difference among the groups(p>0.05). 2. Except for the immediate time after treatment, fluoride levels followed as APF gel>neutral gel>F-rinse>F-paste. There was no statistical difference between the salivary F concentration of F-paste group and that of control group after 2 hours. In case of F-rinse group, after 3 hours the concentration had dropped to baseline value. But there was statistically significant difference among the F concentraion of F gel groups and that of control group(p<0.05). 3. The mean $AUC_{0-120min}$ values were followed as neutral gel>APF gel>F-rinse>F-paste, and the values of the two former groups were significantly higher than those of the two latter groups(p<0.05).
Objective: This study aimed to investigate the relation between rinsing time and the change in enamel surface after fluoride application on the enamel surface. Methods: We recruited two sample groups with different mouth rinsing times. While one group rinsed the teeth immediately after applying acidulated phosphate fluoride (APF) gel, the other group rinsed the teeth 30 minutes after APF gel application. In each group, we performed the following four-step experiment: (i) apply APF gel on the teeth, (ii) rinse the teeth, (iii) immerse the teeth in orange juice, and (iv) measure enamel surface microhardness and scan enamel surfaces. Results: The group that rinsed 30 minutes after treatment exhibited greater microhardness than the group that rinsed immediately after fluoride treatment. The former also showed smooth and regular crystallization, whereas the latter showed rough and damaged crystallization and irregular surfaces. Conclusions: Based on these observations, we conclude that delaying the rinsing time improves the dental caries preventive effect of fluoride.
Background: Dental caries is one of several prevalent oral diseases caused by dental plaque biofilms. This study evaluated the anti-cariogenic effects of a bamboo salt (BS) and sodium fluoride (NaF) mixture on oral bacteria. Methods: The effects of several mixtures of NaF and BS on acid production, growth, and adhesion to glass beads of Streptococcus mutans, and their anti-cariogenic properties were investigated. The growth of S. mutans was measured according to optical density at 3, 6, 9, 12, 15, 18, and 24 hours after treatment using spectrophotometry at a wavelength of 600 nm, while pH was measured using a pH meter. Adhesion of S. mutans was measured according to the weight of glass beads from each group before and after incubation. Gene expression was measured using real-time polymerase chain reaction. Acid production and growth patterns of S. mutans were compared using repeated measures analysis of variance, followed by Scheffe's post-hoc test. The Kruskal-Wallis test was used to compare adhesion, followed by the Mann-Whitney test. Gene expression in the experimental and control samples was compared using the Student's t-test. Results: Growth, acid production, and adhesion of S. mutans were inhibited in all experimental groups. Expression of gft and fructosyltransferase in S. mutans was inhibited in all groups. A mixture of NaF and BS significantly reduced growth, acid production, adhesion, and gene expression of S. mutans compared with the other groups. Conclusion: Results of the present study demonstrated that a mixture of NaF and BS was useful as a mouth rinse in preventing dental caries.
The purpose of this paper is to review two recently reported, long-term studies of several chemical methods to control gingivitis and decalcification in adolescent orthodontic patients. The first study(gingivitis study) was designed to determine whether conventional toothbrushing and twice daily use of a brush-on 0.4 per cent $SnF_2$ gel containing more than 90 per cent available $Sn^{2+}$ would be more effective for controlling plaque accumulation and gingivitis in the presence of orthodontic appliances than conventional toothbrushing alone. The second study(decalcification study) was designed to compare the effectiveness of controlling decalcification in orthodontic patients with either a II00 ppm F tooth paste used alone, this same toothpaste and a 0.05 percent NaF rinse or this toothpaste and a 0.4 percent $SnF_2$ gel. In the gingivitis study, sixty-five consecutively treated adolescents who were to receive full-mouth fixed orthodontic appliances were assigned to two groups according to age and sex criteria. In the decalcification study an additional 30 subjects(95 total) were similarly assigned to a third group. The first group(control, n=35) used only toothbrushing with a standard fluoride(1100 ppm F) toothpaste. The second group used toothbrushing with a similar dentifrice supplemented with a 0.4 percent $SnF_2$ gel($SnF_2$ gel group, n=30) used twice daily for the entire 18-month study period. The third group(in the decalcification study only) used a similar toothpaste and 0.05 percent NaF rinse(NgF rinse group, n=30). Clinical assessments of plaque accumulation using the Plaque Index, gingival inflammation using the Gingival Index, and coronal staining were completed single-blinded before appliances were placed and 1, 3, 6, 9, 12 and 18 months after appliances were placed. Decalcification was assessed single blind on all labial surfaces of all erupted teeth before appliances were placed and 3 months after appliances were removed. The results of the gingivitis study indicated that the $SnF_2$ gel gorup had significantly lower scores for the Plaque Index(p<0.01) and Gingival Index(p<0.001) at all examinations during orthodontic treatment than did the control group. In the $SnF_2$ gel group, one subject developed mild coronal staining and two subjects developed moderate staining. In the decalcification study, when pre-treatment levels of decalcification were subtracted from post-treatment values, significantly lower decalcification scores(p<0.05) were found for both whole mouth and first molars in the NaF rinse and gel groups as compared with the control gorup(toothpaste alone). Although the gel group consistently had less decalcification than the rinse group, this difference only approached statistical significance.
Introduction : Inadequate oral health control is a major risk of oral diseases. Regular home-based care is essential to maintain good oral hygiene. In particular, mouthrinses can support conventional tooth brushing in reducing accumulation of oral plaque. Effect : Antimicrobial mouthrinses are used as part of daily oral care to reduce plaque and gingivitis. Mouthrinses contains fluoride could help remineralization of enamel and dentin. The most common molecules contained in mouthrinses are chlorhexidine, essential oils, cetyl pyridinium chloride, triclosan, hyaluronic acid. Currently, chlorhexidine is the most efficacious compound, with both antiplaque and antibacterial activities. Similar results are reported for essential oils and cetyl pyridinium chloride, although with a somewhat reduced efficacy. Considering the adverse effects of chlorhexidine and its time-related characteristics, this molecule may best be indicated for acute/short term use, while essential oils and cetyl pyridinium chloride may be appropriate for long-term, maintenance treatment. Conclusion and suggestion : Antimicrobial mouthrinses are safe and effective, and when used in conjunction with brushing and flossing, they are an important method of reducing plaque and gingivitis. To improve compliance, dental health care professionals should adapt oral health care recommendations to fit patients' specific needs.
The purpose of this study was to collect basic data for the development of oral health education program of parents and to encourage their actual interest and participation in school oral health program. The authors surveyed parents' awareness and behaviors about the oral health of their children. The subjects in this study were 193 parents of elementary school children in Seoul. The collected data were analyzed, the obtained results were as follows: 1. Thirty-five percent of the parents investigated paid a regular visit to a dental clinic. The most common tooth brushing time among them was after dinner, the second was after breakfast, and this was followed by before bedtime and before breakfast 2. Ninety-four percent of the parents responded that prevention is necessary, 92.2% had a plan to visit a dental clinic to prevent dental caries, and 60.1% experienced receiving pit and fissure sealants. Ninety-seven percent responded that they did check their children's dental caries. 54.9% checked their children's oral status after tooth brushing. The parents who visit a dental clinic on a regular basis were more likely to check their children's teeth after tooth brushing than those who don't(P<0.05). 3. Eighty eight percent of respondents wanted to keep the fluoride mouth rinse program. 4. It is recommended that an oral health education program be developed for parents to visit dental clinics on a regular basis, to educate as to the right tooth brushing time, and to check out their children's oral status after tooth brushing.
