Purpose: This study aimed to evaluate the effects of a cetylpyridinium chloride (CPC) and tranexamic acid (TXA) mouth rinse on patients with gingivitis. Methods: This randomized, placebo-controlled, double-blind, parallel-group, clinical trial included 45 healthy adults with gingivitis, who were randomized into 2 groups. The experimental group used a 0.05% CPC and 0.05% TXA mouth rinse, and the control group used a placebo mouth rinse. The following clinical indices were assessed at baseline, at 3 weeks, and at 6 weeks: the Turesky-Quigley-Hein plaque index (QHI), the $L{\ddot{o}}e-Silness$ gingival index (GI), and bleeding on marginal probing (BOMP). The subjects used the mouth rinse during the experimental period for 20 seconds, 4-5 times daily (10 mL each time). Results: There were no significant differences in the clinical indices between the groups at baseline. In the experimental group (CPC+TXA), a statistically significant improvement was evident in the QHI, GI, and BOMP at 3 and 6 weeks. These results were similar to those observed in the control group at 3 and 6 weeks, although the change in BOMP was not statistically significant in that group. At 6 weeks, the experimental group had a significantly lower mean score for the QHI than the control group. Conclusions: This study demonstrated that a CPC and TXA mouth rinse exhibited significant antiplaque and anti-gingivitis efficacy, and had a positive effect on bleeding control when used daily for 6 weeks.

Objective: To assess the safety and effectiveness of a mouth-rinse with G-CSF (JiSaiXin, produced by NCPC Biotechnology Co., Ltd) in treating patients with chemotherapy-induced oral mucositis (CIM). Method: A consecutive cohort of patients with advanced cancers and CIM were treated with mouth-rinse G-CSF. All chemotherapy for patients with advanced cancers was adopted from regimens suggested by NCCN guidelines. The mouth-rinse with G-CSF at a dose of 150-300ug plus 100ml-500ml normal saline was started from the time of oral mucositis was confirmed and continuously used for at least 7 days as one course. After at least two courses of treatment, safety and efficacy were evaluated. Results: There were 7 female and 7 male patients with advanced cancer and CIM recruited into this study, including 5 with colorectal, 2 with lung, 1 patient with gastric, 1 with cervical and 1 with pancreatic cancer, as well as 2 patients with diffuse large B cell lymphomas, 1 with nasopharyngeal and 1 with gastric cancer. The median age was 57 (41-79) years. Grade 1 to 2 myelosuppression was observed in 3/14 patients, and Grade 4 myelosuppression in 1/14. Adverse effects on the gastrointestinal tract were documented in 5/14 patients, and were Grade 1 to Grade 3. No treatment related death was documented. Regarding CIM, the median response time to mouth rinse of G-CSF was 2 (1-5) days, and all patients with CIM demonstrated a positive response. Conclusions: Mouth-rinse with G-CSF proved to be safe and effective in treating patients with advanced cancers and CIM. However, further randomized controlled studies should be conducted to clarify the effectiveness of this treatment with other lesions.

Objectives: The purpose of this study was to identify the effects of xylitol and sorbitol mouth rinse on the salivary caries activity levels. Methods: The study subjects were 38 female college students in Gyeongju, Korea. The subjects visited the institution once a week for 4 weeks and the saliva samples were measured for the amount of salivary caries activity levels. The saliva was collected 5 times and incubated in Mitis Salivarius Agar for 48 hours(VS-1203P3L, Vision, Korea) and measured. Results: The Streptococcus mutans CFU decreased by statistically significant amounts as compared to before the experiment within the xylitol group and the sorbitol group(p<0.01). After three weeks of mouth rinse application, Streptococcus mutans CFU of the xylitol group and the sorbitol group showed statistically significant differences(p<0.05). The salivary flow rates within the xylitol group and sorbitol group increased by statistically significant amounts(p<0.01) than before the test. The change in the salivary buffering capacity decreased by a statistically significant amount as compared to before experiment within the xylitol group(p<0.01). Conclusions: The salivary caries activity levels decreased after using xylitol and sorbitol mouth rinse in CFU and the flow rate. The buffering activity levels increased within the xylitol group. Further follow-up studies would be necessary to identify the various effects of xylitol.

This study was performed to investigate the effect of three modalities commonly used for reduction of oral malodor and to review the contributing factors for halitosis. For this study, 45 subjects of good general health in their third decades were selected, and they were divided into three groups by each modality, that is, tongue scraping, $ZnCl_2$ mouth rinse, and periodontal treatment. Subjective sense of halitosis, diets, Oral hygiene index based on tooth brushing and tongue brushing habit, resting salivary flow rate, gingival index, degree of tongue coating were recored in the Halito-Chart designed by the author. Oral malodor converted from volatile sulfur compound was measured by the Halimeter$^{(R)}$(Interscan Co., USA), and the correlation between the oral factors and pre-treatment halimeter score were analysed. Data obtained were analysed by the SPSS windows program and the results of this study were as follows : 1. There were no significant correlation between oral factors such as oral hygiene index, salivary flow rate, gingival index, degree of tongue coating and pre-treatment halimeter score. 2. Difference between pre- and post-treatment halimeter score by the three modalities were significant, but correlation between pre- and post-treatment score within group was most significant in the periodontal treatment group followed by the tongue scraping group and lowest in the $ZnCl_2$ mouth rinse group. 3. Reduction of halimeter score was significant only in subjects with relatively more tongue coating in the tongue scraping group, but in the $ZnCl_2$ mouth rinse group and in the periodontal treatment group, the modality applied to each group had same significant effects without regard to the degree of oral hygiene index or gingival index. 4. Men had more tongue coating than women, and reduction of halimeter score was significant in men, but not in women.

Objectives: To confirm the antibacterial effects of each mouth rinse on multiple oral biofilms in vitro. Methods: The antibacterial effects of different mouth rinses were examined by ATP and counted colony forming units (CFU). Preformed oral biofilms on saliva coated hydroxyapatite (sHA) disks were treated with essential oil and saline; then, the multiple oral biofilms were observed by Scanning electron microscope (SEM). RNA sequencing analysis was performed on total RNA isolated from old biofilms of P. intermedia ATCC 49046. Results: In the CFU measured result compared to controls, preformed multiple oral biofilms were reduced from a low of 39.0% to 95.7% (p<0.05). The size of bacterial cells changed after treatment with the essential oil, and some of the cells ruptured into small pieces of cell debris. Gene expression in P. intermedia ATCC 49046 significantly altered in RNA transcribed and protein translated genes after exposure to essential oil. Conclusions: Mouth rinse solutions with different ingredients had different antibacterial effects and may alter surface structure and gene expression as determined by RNA sequencing.

The purpose of this study was to assess the clinical and microbiological effect of chlorhexidine rinse following scaling and root planing on periodontits. 10 patients with periodontal disease were selected for the study. They had not taken antibiotics for months and no history of dental treatment for 6 months before the study. They were good in general health. Patients received a scaling and root planing under local infiltration anesthesia, chlorhexidine rise group were subjected to twice a day 0.1% chlorhexidine rinse for a period 2 week. After initial clinical(plaque index, gingival index, probing pocket depth), microbiological and BANA tests were determined, each subject received a single session of scaling and root planing but no oral hygiene instructions. Clinical indices were measured, microbial parameters and BANA test were reassessed 1, 2 and 4 weeks after treatment. The results were as follows : 1. Plaque index, gingival index and pocket depth in chlorhexidine rinse group and control group were not significantly reduce during all weeks when compared chlorhexidine rinse group with control groups. Plaque index in chlorhexidine rinse group and control group were siginificantly reduced at 1, 2, 4weeks(P<0.05), gingival index and pocket depth wee ignificantly reduced at 2, 4weeks in both groups(P<0.05). 2. Perecntage of cocci and motile rods was significantly changed at 1, 2, 4weeks in chlorhexidine rinse group(P<0.05), control group was significantly changed at 4weeks in control group(P<0.05), intergroup difference was significantly at 2weeks in cocci and 4weeks in motile rods(P<0.05). 3. Percentage of non-motile rods in all group were not significantly changed when compared with those of baseline. 4. Percentage of spirochetes was significantly reduced at 4 week(P<0.05), control group was not significantly reduced during all weeks. 5. BANA test scores was significantly reduced during all weeks in chlorhexidine rinse group(P<0.05), control group was not significantly reduced during all weeks. The result showed that clinical and microbiological effect following scaling, root palning and chlorhexidine on periodontal disease.

Black staining of the teeth in children and adolescents does not cause pain or serious illness, but it can be socially debilitating for esthetic reasons. Black staining is easily removed through periodic professional mechanical tooth cleaning and ultrasonic scaling, but it can easily recur within few months. Using essential oil-containing mouth rinses diluted at 50% twice per day could prevent the black staining from returning after it is removed, reducing the need for mechanical treatments and improving esthetics.

Purpose: This study assessed the effectiveness of three antimicrobial mouthrinses in reducing microbial growth on photostimulable phosphor (PSP) plates. Materials and Methods: Prior to performing a full-mouth radiographic survey (FMX), subjects were asked to rinse with one of the three test rinses ($Listerine^{(R)}$, $Decapinol^{(R)}$, or chlorhexidine oral rinse 0.12%) or to refrain from rinsing. Four PSP plates were sampled from each FMX through collection into sterile containers upon exiting the scanner. Flame-sterilized forceps were used to transfer the PSP plates onto blood agar plates (5% sheep blood agar). The blood agar plates were incubated at $37^{\circ}C$ for up to 72 h. An environmental control blood agar plate was incubated with each batch. Additionally, for control, 25 gas-sterilized PSP plates were plated onto blood agar and analyzed. Results: The mean number of bacterial colonies per plate was the lowest in the chlorhexidine group, followed by the Decapinol, Listerine, and the no rinse negative control groups. Only the chlorhexidine and Listerine groups were significantly different (p=0.005). No growth was observed for the 25 gas-sterilized control plates or the environmental control blood agar plates. Conclusion: The mean number of bacterial colonies was the lowest in the chlorhexidine group, followed by the Decapinol, Listerine, and the no rinse groups. Nonetheless, a statistically significant difference was found only in the case of Listerine. Additional research is needed to test whether a higher concentration (0.2%) or longer exposure period (two consecutive 30 s rinse periods) would be helpful in reducing PSP plate contamination further with chlorhexidine.

The purpose of this study was to propose a method for the effective management of toothbrush contamination. Toothbrush microbial contamination was analyzed according to the duration of toothbrush use, frequency of toothbrush use per day, and toothbrush storage location. We also analyzed the microbial reduction effect of vinegar, antimicrobial mouth rinse, bamboo salt, and baking soda, which are sterilization materials that can be easily used every day. We collected 45 toothbrushes from university dormitories from May to June 2018. To determine the degree of microbiological contamination with general bacteria, coliform bacteria, and Staphylococcus aureus, bristle samples were cultured at $36^{\circ}C$ for 24 hours using 3M$^{TM}$ Petrifilm plates and then measured based on Petrifilm evaluation criteria. Toothbrush microorganisms were analyzed according to the duration of use, frequency of use per day, storage location, and effect of each sterilization material. General bacteria, coliforms, and S. aureus contamination increased with frequency and duration of use (p<0.05). In particular, S. aureus showed a statistically significant increase to 36.15 CFU/ml after 1 month, 504.23 CFU/ml after 2 months, and 2,386.67 CFU/ml after 3 months (p<0.05). We found that 1% vinegar was the most effective substance for reducing general bacteria, coliforms, and S. aureus. In addition, 1% antimicrobial mouth rinse solution applied for 5 minutes was the most effective in reducing S. aureus. It is crucial to recognize the importance of toothbrush care and store toothbrushes in a dry place and replace them periodically. We recommend use of vinegar and antimicrobial mouth rinse solution to disinfect toothbrushes. These should be applied as a 1% solution for at least 1 minute. Proper care of toothbrushes is important in maintaining oral health as well as overall health. Instructions on toothbrush care should be given when teaching children or adults how to brush teeth.
