  • Oral disease causes a significant health and economic burden worldwide, significantly reducing people's quality of life. Dental caries, a representative oral disease, is caused by S. mutans. Oral pathogenic microorganisms contain lipopolysaccharide (LPS), which can cause an immune response and cause various oral diseases. The purpose of this study was to investigate the antioxidant and antibacterial effects of bamboo leaf extract (BLE) to control oral diseases. THP-1, oral fibroblasts, and S mutans culture medium were treated with bamboo leaf extract at different concentrations of 0-8% to conduct the experiment.. As a result, the antioxidant effect according to the BLE concentration was confirmed in mononuclear cell lines and oral fibroblasts. In addition, the antibacterial effect of S. mutans according to the BLE concentration was demonstrated. Therefore, BLE can be used for the prevention or treatment of oral diseases.

  • Helicobacter pylori(H. pylori) is bacterial infection, with more than half of the world population infected and oral cavity is considered second reservoir of H. pylori infection. The purpose of this study was to evaluate role of oral cavity in H. pylori infection by comparison of the mode H. pylori infection in oral cavity and stomach. We recruited 100 subjects without systemic disease including gastrointestinal disease. Samples in oral cavity taken on gingival sulcus fluid(GSF) of lower left central incisor and 1st molar, area of buccal mucosa, dorsum of the tongue, palatal and saliva. We analyzed by Nested polymerase chain reaction(PCR) for oral infection and Urea Breath Test(UBT) for gastric infection. The results were as follows : 1. Among these 100 subjects, 36(36%) were positive by Nested PCR and 33(33%) were positive by UBT(p>0.05). 2. In detection rate of H. pylori in sites taken sample, 11(11%), 8(8%), 9(9%), 3(3%), 9(9%), 7(7%) were positive on GSF of lower left central incisor and 1st molar, area of buccal mucosa, dorsum of the tongue, palatal and saliva, respectively. Statical significance was observed in samples of GSF of lower left central incisor and area of dorsum of the tongue(p<0.05). 3. In comparison of the mode of H. pylori infection in oral cavity and stomach by analytic method, positive in oral cavity and stomach was 10(10%), negative in oral cavity and positive in stomach was 23(23%), positive in oral cavity and negative in stomach was 26(26%) and negative in oral cavity and stomach was 41(41%)(p>0.05). Conclusively, we can guess that oral H. pylori is not associated with gastric H. pylori infection and normal flora.

  • S. mutans is the most important causative bacteria of dental caries among the oral bacteria. S. salivarius is a normal inhabitant in the human oral cavity. Nine strains of S. salivarius in this study were isolated from the oral cavities of children and identified, and their effect on S. mutans and S. oralis was studied. 1. The mean weight of produced artificial plaque on the wires in the beaker was 204.9 mg in the culture of S. mutans only, whereas being reduced to 1.9 mg through 20.6mg in the combined culture of S. mutans and each S. salivarius isolate (p<0.05). The viable cell didn't show the difference between them after culturing. 2. When S. mutans was cultured in the media containing culture supernatant of each S. salivarius isolate in M17 broth, the mean weight of produced artificial plaque was 117.1 mg on the wires, whereas being 47.7 mg in the media containing culture supernatant of each S. salivarius isolate in M17 broth containing 5% sucrose. 3. The polymer produced by S. salivarius isolates was on the thin layer chromatography. 4. Inulin and levan didn't inhibit the formation of artificial plaque by S. mutans in the beaker test. These results suggested that fructan-producing S. salivarius isolates inhibited the formation of artificial plaque by S. mutans.

  • This study aimed to suggest the optimum number of rinsing by researching changes in optical density and pH in accordance with the number of rinsing after toothbrushing, and then verifying the amount of residual toothpaste in mouth. Total 14 university students who had healthy body with no difficulties in daily life were selected from the students of K university in Daegu as the research subjects. The research subjects rinsed their mouths with 40ml of water from zero time to 12 times after toothbrushing. After collecting each rinsing water, the optical density and pH were measured. In the results of measuring the optical density value of each rinsing water, the rinsing water of six-seven times or more after toothbrushing showed the constant value of optical density, which was statistically significant(p<0.05). There were no differences in accordance with the amount of toothpaste such as 1g, 1.5g, and 2g. Based on such results of this study, it would be necessary to provide the education of the use of dentifrice, and also to have diverse researches on the effects of residual dentifrice in mouth on the oral cavity.

  • In this study, low molecular weight chitosan (LC) was added to dental cement liquid at 0, 0.5, 1.0, and 2.0 wt% by weight for surface properties and oral bacteria adhesive of dental cement. The evaluated by net setting time and surface properties of surface energy on the surface roughness. The degree of oral bacterial adhesion was assessed using two strains of oral bacteria, S. mutans and E.coli. The results showed that the setting time at the LC0.5 group increased no statistically difference was observed (p<0.05). The surface roughness statically significant LC2.0 group and oral bacteria adhesion experiment results in contrast to the control group LC0, LC-added experimental group showed a somewhat lower adherent surface statistically significant difference was observed (p<0.05). It seems that this LC proved that surface properties and oral bacteria adhesion effect was demonstrated. Therefore, it was suggest that the additional effects of LC and research on a wide range of substances.

  • The purpose of this study is to emphasis the fact that the oral cavity should be well-managed as it is where the intake of the valuable nutrition for the baby is made, among many other important factors and changes that the pregnant women go through as they prepare for the birth of a human being for 10 months. For this, we surveyed the management of the oral hygiene and the awareness of oral health by the pregnant women. The result showed that the nauseating during the brushing of the teeth and the use of the oral hygienic products varied among different standard of lives with statistical significance. As for the standard of living, those in higher level showed also a higher level of the use, while the middle and low standard of living showed lower level of usage of the oral hygienic products. In case of the dental treatment during the pregnancy, most of the interviewees answered they do not receive dental treatment during pregnancy in the fear of bad influence on the baby and the potential risk of congenital anomaly. The perceived necessity of the education on the oral health was generally high. And, for the contents of such education, they preferred the timing of the dental treatment, the content of the treatment, and misunderstandings regarding the dental treatment.

  • This study carried out questionnaire survey and experiment on oral hygiene effects according to the actual condition of using oral care products and the amount of toothpaste used targeting 40 freshmen and sophomores in dental hygienics in some universities from November 8, 2010 to November 26. The collected data was analyzed by using SPSS WIN 15.0 program. The following conclusions were obtained. 1. The result of actual condition of toothbrushing is as follows. As the answer of a question about whether or not toothbrushing after every meal at ordinary times, the largest was 47.5% of being average. The occasion of toothbrushing before going to bed at ordinary times was the largest with 47.5%. The daily toothbrushing frequency was 3 times mostly and the general toothbrushing method at ordinary times was a rolling method. The frequency of exchanging toothbrushes for the past 1 year was 3 times, which is the largest with 45.0%. 2. As a result of the actual condition of using oral care products, the majority of students don't use electric toothbrush, interdental brush, or mouth-rinse except dental floss. Accordingly, there need to be education and promotion with diverse methods so that a patient oneself can prevent oral disease by selecting and using oral care products that are proper for each individual. Also, it was indicated that there is no big difference in oral hygiene effects depending on the amount of toothpaste used. Thus, to avoid wasting toothpaste, we need to educate and promote to use the amount of toothpaste under 0.3g.
