    Abstract PDF
    Objectives : The purpose of the present study was to investigate the effect of bamboo charcoalon Streptococcus mutans which is one of the most important causative agents of dental caries. Methods : S. mutans was incubated with or without bamboo charcoal and then changes wereobserved in its cell viability and antibacterial effect. Oral epithelial cells viabillity(human gingivalfibroblast, HGF) was performed using MTT assay. Antibacterial effect was analyzed using a dilutionplating method and agar diffusion method. Results : Oral epithelial cells, human gingival fibroblast (HGF) showed a tendency to increasein bamboo charcoal treatment solution concentrations(0.5 , 1, 2 , 3 , 5, 10%). The bamboocharcoal had an antibacterial effect on S. mutans. Antibacterial effect of bamboo charcoal forthe bacterium was 58%. Charcoal concentration of 2% and 5% in the inhibition zone showeda minimal growth, but the concentration of 10% bamboo charcoal in inhibition zone revealeda conspicuous antibacterial activity.

    안재현 | 김지혜 | 김종훈 and 3other persons | 2014, 14(1) | pp.101~108 | number of Cited : 5
    Abstract PDF
    Objectives : The purpose of this study was to evaluate the tooth whitening effect of 0.74%and 2.80% hydrogen peroxide toothpastes and safety on tooth and gingival tissue. Methods : Toothpastes containing 0.74% and 2.80% hydrogen peroxide were evaluated. Inin-vitro test, some additives (sodium metaphosphate, sodium pyrophosphate and titanium dioxide)were added to the toothpastes. Hydroxyapatite specimens (HAPs) were made and stained usingmodified Stookey’s methods. HAPs were treated for 1 hour at shaking incubator and brushedfor 1,000 times as 250 gF with each diluted toothpaste. Before and after color was measuredby colorimeter. Using double blind method, 99 Korean with natural maxillary anterior teeth wereselected and the initial brightness (baseline) was measured by SHADEEYE-EX. Based on thismeasurement they were crossly distributed into control group (0% hydrogen peroxide), test 1(0.74% hydrogen peroxide) and test 2 (2.80% hydrogen peroxide). After 2 weeks, people ofeach group were provided toothpaste and told to use 3 times a day right after every meal for3 minutes. The brightness of teeth was measured 3 times for every one month. Results : ΔL was statistically significant among three groups in shaking test. ΔL of two testgroups was statistically significant compared with control group but not between each test groupin brushing test. After using toothpaste for 3 months, test 1 group and test 2 group were 15.89%and 31.23% more whitened compared with control group respectively (p<0.05). Rate of morewhitened person of each test group was 24.2% and 40.5% more than control group respectively(p<0.05). There was no difference in the hypersensitivity during 3 months using toothpastes andno side effect on teeth or gums. Conclusions : Toothpastes containing 0.74% and 2.80% hydrogen peroxide showed toothwhitening effect and both were safe enough to use for tooth whitening.

Methods : The inhibitory effect of lotus leaf extracts on the growth of oral bacteria was assessedin experiments with extracts from freshly harvested and pulverized lotus leaves and bacterial culturesof dental caries. Results : The results showed that N. nucifera extracts possess antimicrobial activity on all bacterialstrains. The minimal inhibitory concentration (MIC) values varied from 4 mg/ml to 10 mg/mlagainst antimicrobial activity. The relative growth ratio (RGR) against of N. nucifera extracts weredetermined as 50% in concentration of 4.0 mg/ml. The extract of N. nucifera was effective inreducing on the glucosyltransferase (GTase) activity of six strains in vitro. Conclusions : Methanol extracts of lotus leaves showed antimicrobial effects on three bacterialspecies causing dental caries and three bacterial species causing periodontitis, as well as inhibitoryeffects on GTase activity.
