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.

Gargle solution has typically been used for the prevention of oral infectious disease such as dental caries and periodontitis. However, the use of most gargle solutions is controversial in application for children because some gargle solutions have harmful side effects. Electrolyzed water is generated by passed an electric current and has antimicrobial activity. The purpose of this study was to investigate and compare the efficacy of electrolyzed water in various conditions for eliminating cariogenic bacteria. Electrolyzed water was generated by a platinum electrode in the presence of sodium chloride at various concentrations. Streptococcus mutans and Streptococcus sobrinus were cultivated into a brain heart infusion broth. After harvesting planktonic bacteria, the pellets were treated with the electrolyzed water and commercial gargle solutions and plated on a mitis-salivarius agar plate. Also, the anti-biofilm activity of the electrolyzed water and commercial gargle solutions was investigated after biofilm formation of S. mutans and S. sobrinus. The bacteria in the biofilm were plated onto a mitis-salivarius agar plate. The plates were incubated, and the colony forming unit was measured. The electrolyzed water containing sodium chloride showed significant antibacterial activity against S. mutans and S. sobrinus as well as some gargle solutions. Furthermore, the electrolyzed water had more disruptive effect on the biofilm of S. mutans and S. sobrinus and killed more bacteria in the biofilm than commercial gargle solutions. The results demonstrate that electrolyzed water may be a useful gargle solution for prevention of dental caries.

Objectives: The aim of this study was to investigate deodorizing effectsof medicinal herbs (Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex, Angelicae Dahuricae Radix) for development of a gargle solution. Methods: 1. The antimicrobial effects of medicinal herbs were evaluated with the minimal bactericidal concentration (MBC) and the change of the number of viable cells in the herb extracts(1%) for 48 hrs against P. gingivalis 2561 and Pr. intermedia ATCC 25611. 2. Deodorizing activity of each herb and Garglin $Mint^{(R)}$gainst methyl mercaptan were analyzed by gas chromatography (GC). 3. We used the malodor modeling of the salivary sediment system with a Halimeter. 4. In the preliminary clinical study, the baseline concentration of VSC in the oral cavity of each subject was measured by Halimeter. Subjects would gargle for 30 seconds with cysteine. After 4 minutes subjects would gargle for 30 seconds with Garglin and herb extracts (2%). Subsequently, concentration of VSC were measured at 0, 4, 8, 12 and 20 minutes. Results: 1. MBC of Mume Fructusfor P. gingivalis 2561 was determined to be <1% and MBCs of Eriobotryae Folium for P. gingivalis 2561 and Pr. intermedia ATCC 25611 were determined to be <2% and <1%, respectively. Mume Fructus (1%) completely suppressed the P. gingivalis cell viability from 5 hrs and Eriobotryae Folium (1%) completely suppressed the Pr. intermedia cell viability from 48 hrs. 2. In GC analysis, deodorizing activities were 91.54% with Mume Fructus, 87.97% with Eriobotryae Folium, 100% with Acanthopanacis Cortex, 72.36% with Angelicae Dahuricae Radix and 40.54% with Garglin $Mint^{(R)}$. 3. In malodor modeling of the salivary sediment system, each of the medicinal herbs had significantly inhibitory effect on malodor formation (p<0.05). 4. In the preliminary clinical study, the concentration of VSC of the herb groups was significantly lower than of the control group, but not in Garglin $Mint^{(R)}$. Conclusions: Mume Fructus, Eriobotryae Folium, Acanthopanacis Cortex and Angelicae Dahuricae Radixhave deodorizing activities and potential as an effective mouthwash against oral malodor.

Background and Objectives : This study is an observational study of nonequivalent control group based on time lag design in order to determine the effectiveness of gargling Hwangryunhaedok-tang (HRHDT) on stomatitis caused by chemotherapy. Methods : The study period is from July 1st, 2010 to September 30th, 2010. The subjects are 13 patients who fit the profile of the study and who are admitted in the tumor department of the regional cancer center of C University Hospital which is located in Chung-Joo City. When stomatitis occurs after chemotherapy, the level of stomatitis is assessed using oral assessment guide score and oral discomfort score. Then mix 5 g of powered HRHDT and 60 ml of distilled water, and 15 ml of the solution is given to patients 4 times per day to gargle for 1 minute. For the control group, 60 ml of Chlorohexidin gargling solution is used; everyday for one week, 4 times per day, 15 ml per gargle and gargled for 1 minute. Oral Assessment Guide score and Oral Discomfort Score are assessed at same hour everyday. Crosstabulation analysis $X^2$(${\rho}$) was used to examine the demographic characteristics and difference of the two groups by using SPSS/WIN 12.0. For mean and standard deviation, descriptive statistical analysis was used. T-test was used to determine the difference of the oral discomfort scores. Result : The study has shown that the Oral Assessment Guide score of the experimental group has decreased more with more regularity. On the third day, the score of the control group is 20.16 and the score of the experimental group was 18.75, which showed a statistically significant difference with the level of significance of p<0.05. Oral Discomfort Score of the control group's score was 13.60 on the first day and 6.80 on the seventh day and the experimental group's score was 13.00 on the first day and 2.25 on the seventh day. The experimental group's score 2.25 is statistically significantly lower than the control group's score of 6.80 with the level of significance of p<0.05. Conclusions : The HRHDT gargling solution showed more regular effectiveness compared to Chlorohexidin solution on chemotherapy-caused stomatitis. Therefore this study has shown that HRHDT gargling solution can be used as an alternative medicine.

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.

Objective: We investigated the oral malodor inhibitory effect of Scutellariae Radix (SR), Phellodendri Cortex (PC), Moutan Cortex (MTC) and Magnoliae Cortex (MGC) for the development of a gargle solution. Methods: 1. Against P. gingivalis and Pr. intermedia, the minimal bactericidal concentration (MBC) and the change of viable cells that were exposed to 1% each herbal extract were observed. 2. Deodorizing activity of 2% herbal extract and Garglin $Mint^{(R)}$ against methyl mercaptan were evaluated by gas chromatography (GC). 3. We used the salivary sediment system (SSS) as the malodor model. 4. The clinical examination was repeated 3 times by 2 subjects by $Halimeter^{(R)}$. Baseline VSC of each subject was measured. Then, the control subject gargled with cysteine for 30 sec. After 4 min, subjects would gargle for 30 seconds with herbal extracts (2%) and Garglin $Mint^{(R)}$. Subsequently, the concentration of VSC was measured at 0, 4, 8, 12, 16, 20, 40 and 60 minutes. Results: 1. Against P. gingivalis, MBC of SR, PC and MTC was 0.1%, and MBC of MGC was 1%. Removal time of P. gingivalis was as follows; 5 hr in MGC, 24 hr in SR and PC, and 48 hr in MTC. Against Pr. intermedia, MBC of SR and PC was 0.5%, and MBC of MTC, MGC was 1%. Removal time of Pr. intermedia was as follows; 5 hr in MTC and 24 hr in SR, PC and MGC. 2. Deodorizing effect of herbal extracts against methyl mercaptan was as follows; MGC and MTC had 100%, SR had 82.22%, PC had 66.60%, Garglin $Mint^{(R)}$ had 40.54%. 3. In the experiment using SSS, PC and MTC had statistically significant malodor-inhibitory effects (p<.05). 4. In the clinical examination, PC and MGC had statistically significant inhibitory effects at every elapsed time compared to the control subject. MTC had that until 40 min. SR had that at 0, 4, 8, 20, and 60 min. Conclusions: SR, PC, MTC and MGC have an antibacterial effect and the chemical removable activity of the oral malodor caused by VSC. These four herbs could have potential as effective anti-malodor agents.

Objectives : This paper is designed to help the public prevent their future dental caries, based on the studies of xylitol about it's efficacy and effectiveness, and its appropriate usage. Methods : This study of xylitol on the basis of existing research papers and literature is not only to learn about the mechanism of what xylitol acts, but also to search the effectiveness of incompleteness of xylitol-containing foods, bacterial infection between xylitol and mother-baby, and the side-effects of xylitol. Results : 1. Xylitol's continuous intake of teeth effects the decrease of calculus amount, cleanness of teeth, as well as the remineralization process. The xylitol effect varies depending on the weight of xylitol, which has no effect on root caries. 2. Mouth gargle solution is higher resistant against acids; recalcification is significantly reduced; and remineralization effect represents. 3. It is reported that regular consumption of xylitol by mothers just during two years after birth has significantly decreased the spread possibility of mutans streptococcei. 4. The reduction of dental caries by xylitol is happened by its restraining the growth of bacteria resource caries, with their presence in amount of uncontrolled growth. 5. When a small amount of eating xylitol is absorbed slowly into gastrointestinal tract, being followed by glucose metabolism in the liver, while its excessive amount of eating can cause gastrointestinal problems. Conclusion : Dental hygienists should be required to provide dental information to the public on the basis of academic knowledge. In situation that one is not yet sure of xylitol on solid and multifaceted researches, there must be needed more accurate and detailed reviews on the side-effects of xylitol and the overall impact on the oral environments.

Purpose: Candida albicans can cause mucosal disease in many vulnerable patients. Also they are associated with denture-related stomatitis. Electrolyzed water is generated by electric current passed via water using various metal electrodes and has antimicrobial activity. The aim of this study was to investigate antifungal activity of electrolyzed water on C. albicans biofilm. Materials and Methods: C. albicans was cultured by sabouraud dextrose broth and F-12 nutrient medium in aerobic and 5% $CO_2$ condition to form blastoconidia (yeast) and hyphae type, respectively. For formation of C. albicans biofilm, C. albicans was cultivated on rough surface 6-well plate by using F-12 nutrient medium in $CO_2$ incubator for 48 hr. After electrolyzing tap water using various metal electrodes, the blastoconidia and hyphal type of C. albicans were treated with electrolyzed water. C. albicans formed blastoconidia and hyphae type when they were cultured by sabouraud dextrose broth and F-12 nutrient medium, respectively. Results: The electrolyzed water using palladium electrode (EWP) exhibited antifungal effect on blastoconidia of C. albicans. Also, the EWP significantly has antifungal activity against C. albicans biofilm and hyphae. In the electrolyzed water using various metal electrodes, only the EWP have antifungal activity. Conclusion: The EWP may use a gargle solution and a soaking solution for prevention of oral candidiasis and denture-related stomatitis due to antifungal activity.
