Objectives: The purpose of the study was to identify the oral care status and periodontal disease of middle aged daibetic patients in Korea. Methods: The primitive data were taken from 238 diabetic people in the 5th Korea National Health and Nutrition Examination Survey(KNHANES) in 2010 - 2012. The variables included general profiles(gender, age, occupied area, education, and smoking), oral care status(brushing time, brushing time, use of oral hygienic supplies, availability of oral hygienic supplies, oral examination, and recognition of oral health state), and diabetes management(morbidity period, treatment, education, and glycosylated hemoglobin levels). Results: Most of the subjects took gargling more than twice a day and it accounted for 73.5%. Oral hygienic supply users accounted for 24.8%, and most of them used floss brush. Oral examination was done in 19.3% of the respondents and 55.0% thought that their oral health status were very poor. The prevalence rate of the periodontal diseases was 46.6%. Female tended to have a higher rate of periodontal disease than the male. Oral hygienic supply users had lower rate of periodntal disease than those who did not use. Those who had poor subjective oral health status had higher prevalence rate of periodontal disease than those who did not. Conclusions: Periodontal disease is closely related to good oral care of middle aged diabetic patients. It is necessary to develop the program for the prevention of the periodontal disease for the diabetic patients.

Purpose: Pilocarpine as a salivation stimulant in pill form has mostly been used to relieve oral dryness for xerostomic patients but its use may often be limited due to variable side effects from systemic absorption. Therefore, the purpose of this study was to investigate the effects of pilocarpine mouthwash on salivation according to the variable concentration and duration for healthy volunteers. Related adverse effects and subjective assessment on its effects on salivation were also examined. Methods: This study was performed as placebo-controlled, double-blind, randomized clinical trial. Thirty healthy volunteers (male=23, mean age=22.2 years) were randomly allocated to 6 groups with the different concentration of pilocarpine mouthwash (placebo, 0.1%, 0.5%, 1.0%, 1.5%, and 2.0%). The whole experiment consisted of 3 sessions according to the duration of mouthwash, i.e., 1, 3, and 5 minutes with the mean wash-out period ${\geq}2$ days between the sessions. Unstimulated whole saliva was collected before and after gargling with a mouthwash. Results: Salivation of the higher concentration groups ${\geq}1%$ significantly increased than those of lower concentration group. The application period of mouthwash did not cause any changes of salivary flow rate at the higher concentrations ${\geq}1.0%$. The lower concentrations of 0.5% and 0.1% had no effects on salivation even after 5-minute mouthwash. There was no significant difference between blood pressure and pulse rate before and after use of mouthwash. Conclusions: From the results of the current study, pilocarpine mouthwash with at least 1.0% concentration more than a minute might be clinically effective in salivation without any serious side effects. Dose of mouthwash rather than duration seems to be a critical factor to salivation.

The main cause of oral disease is the formation of tooth surface bacteria, and a chemical mouthwash is used as a suppression method. However, chemical preparations have side effects, so we tried to verify the antibacterial effect of bamboo extract against oral microbes. Subjects were 15 college students as a control group and an experimental group, and the changes in oral microbes before and after the use of distilled water and bamboo extract were compared. Analysis of SPSS Windows ver. 20.0 was used (p<0.05). Results The total number of pathogenic microorganisms further decreased after using bamboo extract solution after using gargling solution between groups.

Oral lichen planus(OLP) is a chronic inflammatory disease with cell-mediated immune responses, but the exact cause is unknown. The treatment aim of OLP is not complete cure but to alleviate symptoms. In this study, two kinds of corticosteroid gargling solutions used for comparing the effects. From 2002 to 2010, 180 patients diagnosed with oral lichen planus and received topical steroid therapy in the Pusan National University Dental Hospital. Each of two types of solution contained dexamethasone (dexamethasone disodium phosphate) and prednisolone ($solondo^{(R)}$). A period of relief of symptoms and recurrence was recorded. The group using solution containing dexamethasone(dexa gargle) was prescribed to 33 patients(25 female, 8 male) and another group containing prednisolone (solon gargle) included 147 patients (114 female, 33 male). The effect of dexa gargle seemed faster than the solon gargle. There was no significant difference for recurrent rate between the groups using dexa and solon gargle.

Purpose: To verify the anti-microbiotic activity and to develop eco-friendly surface disinfectants using the Opuntia ficus-indica extract. Methods: The stem and fruits of the Opuntia cultivated in Jeju Island were extracted with hot water, 70% EtOH and 100% MeOH, respectively. To examine the antimicrobial activity of the extracts, gram positive bacteria (Bacillus subtilis, Staphylococcus aureus), gram negative bacteria (Escherichia coli, Salmonella typhimurium), yeast (Candida albicans), mold (Aspergillus flavus) and antibiotic resistant bacteria (E. coli, S. aureus) were measured to form a clear zone. Results: The antibacterial activity of the fruit extract was higher than that of the stem extract, and the antibacterial activity of the 100% MeOH (FM) extract and the 70% EtOH (FE) extract of the palm cactus fruit was suitable for the surface disinfectant overall, and clear-zone formed even at relatively low concentrations (250 mg/mL). The FM and FE have antibacterial activity against various bacteria, therefore they can be used as disinfectants. Conclusion: The antimicrobial activity of Opuntia ficus-indica extract from Jeju Island by stem and fruit was determined at relatively low concentrations (250 mg/mL). The Opuntia ficus-indica extract will be useful for surface disinfectants dissolving the patients' bath, oral gargling, and powdered powder in water or ethanol in appropriate concentrations.

The aim of this study was to investigate the antimicrobial effect of (-)-epigalocatechin on Fusobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis. To test the antimicrobial effect of (-)-epigalocatechin, the minimum inhibitory concentration (MIC) of against 4 strains of F. nucleatum, 2 strains of P. intermedia, and 2 strains of P. gingivalis was measured by broth dilution method. Time-kill curves were assessed for susceptible bacteria, testing $0{\times}MIC$ (control group), $0.5{\times}MIC$, $1{\times}MIC$, and $2{\times}MIC$ for (-)-epigalocatechin, by counting viable bacteria after 3, 90, 180, 360, 720, 1440 minutes. The MIC of (-)-epigalocatechin was 0.312-0.625, 0.625, and 0.625 mg/ml on the strains of F. nucleatum, P. intermedia, and P. gingivalis, respectively. Time-kill curves demonstrated (-)-epigalocatechin had bactericidal activity on P. intermedia ATCC $25611^T$, P. gingival is ATCC 53978, and F. nucleatum subsp. fusiforme ATCC $51190^T$. The results suggest that (-)-epigalocatechin can be useful in developing the oral hygiene product such as tooth past and gargling solution for the prevention of periodontal diseases.

Purpose : Hypochlorous acid (HOCl), a major inorganic bactericidal compound of innate immunity, is effective against a broad range of microorganisms. In particular, HOCl is well-known as a non-antibiotic antimicrobial substance. However, effects of HOCl as an antimicrobial agent are still needed to study these functions against various specific type of microorganisms. In this study, we investigated the antimicrobial effect of hypochlorous acid (HOCl) in S. mutans and A. actinomycetemcomitans to cause dental caries and periodontal disease. Experiments were conducted to observe whether HOCl become effective replacement of disinfectant. Methods : To observe antimicrobial effect of HOCl, stabilized HOCl is prepared in the form of a physiologically balanced solution in pre-conditioned and post-conditioned HOCl solution. As a control, commercially available disinfectant MAXCLEAN was used as positive control. Moreover, S. mutans and A. actinomycetemcomitans distribution in gagrin, filtered tap water, and culture media. Cell viability were measured by viable cell count methods and disk diffusion test. Results : Our results showed that treatment of HOCl have no effect against antimicrobial effect compare to control group especially gagrin in disk diffusion test. HOCl tended to reduced viability against S. mutans in group of post-conditioned than pre-conditioned of HOCl solution however, there was no significant difference as well as no effect in A. actinomycetemcomitans. Conclusion : HOCl showed tendency to reduce viability against S. mutans in group of post-conditioned of HOCl solution and no effect of antimicrobial effect. Although HOCl is well known as effective against a broad range of microorganisms, HOCl seems to have diversity following type of species to be used as antimicrobial drug following our results. Therefore, it is necessary to be rigidly controlled and regulated in using HOCl solution clinically.

The aim of this study was to evaluate the antimicrobial effect of carvacrol against periodontopathic and cariogenic bacteria and its cytotoxicity in human oral tissue cells. We tested their antibacterial properties against mutans streptococci and five major periodontopathic bacterial species involved in periodontal disease. The antimicrobial activity was evaluated by the minimal inhibitory concentration (MIC) and minimum bactericidal concentration (MBC). The cell viability of carvacrol on normal human gingival fibroblast (NHGF) cells was tested by metyl thiazolyl tetrazolium assay. The data showed that carvacrol had remarkable antimicrobial effect on tested bacteria with a MIC and MBC values ranged from 16 to $128{\mu}g/ml$ and from 32 to $128{\mu}g/ml$, respectively. In cell toxicity studies, carvacrol had significantly decreased cell viability when NHGF cells were treated at $128{\mu}g/ml$. These findings suggest that carvacrol has a strong antimicrobial activity against periodontopathic and cariogenic bacteria. However, in order to use it as a component of gargling solution or toothpaste, its concentration should be below $64{\mu}g/ml$ and other compounds having an antimicrobial activity against periodontopathic and cariogenic bacteria should be used together.

The mouth rinsing solution currently on the market is used for oral hygiene and reduction of halitosis, and alkaline ionized water is used for drinking purposes. The aim of this germiculture and observation through a microscope is to investigate the effect they have on the oral bacteria, and the results are as follows. 1. The change in the number of cultivated bacteria before and after the use of gargle was most dramatic for Hexamedin. It showed the highest rate of decrease in bacteria by 71.29%, followed by Listerine with 62.25%, Caregargle with 42.26%, Garglin with 33.52%, saline solution with 21.62%, alkaline ionized water with 16.08% and distilled water with 7.67%. 2. After careful analysis of statistics, Hexamedin was found to result in a significant decrease in the number of bacteria after gargling (p<0.05). 3. From observing through an light microscope after gram staining, it was evident that both a number of cocci and a few of filamentous were present before the use of gargle, whereas mostly cocci was present after the use of gargle. 4. The difference in the pH of oral rinses and alkaline ionized water had no significant influence on the number of oral bacteria. In conclusion, Hexamedin and Listerine, with the rate of decrease of bacteria of co71.29% and 62.25% respectively, have proven to be highly effective when applied before dental treatment. Other oral rinses and alkaline ionized water are relatively less efficient in decreasing the number of oral bacteria. Also, the decrease of bacteria is more affected by the antibacterial component of oral rinses than by the change in pH.
