Many of antimicrobial components used in the mouthwash have disadvantages such as coloring of periodontal tissue and homing sensation. To find the more biocompatible antimicrobial agent, we have screened the 2,125 kinds of natural plant extracts obtained from by the Plant Extract Bank (Daejeon, Korea). The antimicrobial activity was determined by spectrophotometric growth inhibition assay for the major dental pathogens. For the Porphyromonas gingivalis, 19 plant extracts had an antimicrobial activity, 17 plant extracts for the Prevotella intermedia, 45 plant extracts for the Haemophilus actinomycetemcomitans and 85 plant extracts for the Streptococcus mutans. Among these effective extracts, 8 kind of natural plant extracts had an antimicrobial activity for more than 3 species of dental pathogens. In our experiment, Cudrania tricuspidata, Morus bombycis and Mallotus japonicas have antibacterial effects on the all kinds of major dental pathogens. Therefore these plant extracts have a possibility to be a candidate for major antibacterial components in dental products.
Background: Among the health problems in old age, oral health is closely related to nutrition intake and digestion, so although it is an important factor in the well-being of the elderly along with general health, studies examining the relationship between oral health-related factors and grip strength of the elderly are insufficient. Therefore, this study intends to examine the relationship between oral health-related factors and grip strength, which are closely related to the general health of the elderly. Methods: This study used data from the 7th period of Korea National Health and Nutrition Survey (2016~2018) approved by the Research Ethics Review Committee of the Korea Centers for Disease Control and Prevention. Complex sample frequency analysis and descriptive statistics were performed, and general linear model analysis was performed to confirm the relationship between demographic characteristics, oral health -related factors and grip strength. The statistical analysis was performed using IBM SPSS Statistics for Windows, Version 23.0, and the significance test was based on type I error level of 0.05. Results: Grip strength was higher in the case of no discomfort than in the case of discomfort in relation to mastication discomfort and grip strength (B=0.927, p<0.001). In addition, the grip strength was decreased by 1.348 times when not using dental floss (p<0.001) and when not using mouth wash was 1.480 times (p<0.001). Conclusion: In this study, in the relationship between oral health-related factors and grip strength, grip strength was found to be high in the absence of mastication discomfort. and in the case of using dental floss and mouthwash the elderly showed high grip strength. Therefore, it is suggested to present a lifestyle to improve hand function and grip strength in the elderly and develop a program to increase grip strength and provide them at the same time during oral health education.
Purpose: The purpose of this study was to investigate whether various saliva collection methods affect the observed salivary microbiome and whether microbiomes of stimulated and unstimulated saliva and plaque differ in richness and diversity. Methods: Seven sampling methods for unstimulated saliva, stimulated saliva, and plaque samples were applied to six orally and systemically healthy participants. Bacterial 16S ribosomal RNA genes of 10 major oral bacterial species, namely, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, Fusobacterium nucleatum, Prevotella intermedia, Prevotella nigrescens, Streptococcus mitis, Streptococcus sobrinus, and Lactobacillus casei, were analyzed by real-time polymerase chain reaction. We comprehensively examined the dependence of the amount of bacterial ribosomal DNA (rDNA), bacterial-community composition, and relative abundance of each species on sample collection methods. Results: There were significant differences in the bacterial rDNA copy number depending on the collection method in three species: F. nucleatum, P. nigrescens, and S. mitis. The species with the highest richness was S. mitis, with the range from 89.31% to 100.00%, followed by F. nucleatum, P. nigrescens, T. denticola, T. forsythia, and P. intermedia, and the sum of the proportions of the remaining five species was less than 1%. The species with the lowest observed richness was P. gingivalis (<0.1%). The Shannon diversity index was the highest in unstimulated saliva collected with a funnel (4.449). The Shannon diversity index was higher in plaque samples (3.623) than in unstimulated (3.171) and stimulated (3.129) saliva and in mouthwash saliva samples (2.061). Conclusions: The oral microbial profile of saliva samples can be affected by sample collection methods, and saliva differs from plaque in the microbiome. An easy and rapid technique for saliva collection is desirable; however, observed microbial-community composition may more accurately reflect the actual microbiome when unstimulated saliva is assayed.

Purpose : Many studies have confirmed the relationship between physical exercise, chronic diseases, and quality of life, but few of those studies were limited to aerobic exercise. Above all, no research has confirmed the relationship between aerobic exercise and the oral health. This study is significant because it is the first study to confirm the relationship between aerobic exercise, which is practiced more frequently than other exercises, and oral health in adults. Through this study, we hoped to confirm the complex impacts of aerobic exercise on health-related quality of life, oral health-related behavior, and oral health status in adults and to use these impacts as basic data on the importance of aerobic exercise. Methods : In this study, the following analysis was conducted based on a complex sample design that applied stratification variables, cluster variables, and weights using SPSS version 21.0. Complex sample cross-analysis was conducted to identify general characteristics according to aerobic physical activity practice, and oral health-related characteristics according to the aerobic physical activity practice rate. Then, complex sample logistic regression analysis was conducted to determine the effect of aerobic physical activity practice on oral health-related characteristics. During the statistical analysis, missing values were treated as valid values, and the statistical significance level was set at .05. Results : Aerobic physical activity practice was 1.39 times higher among the respondents who brushed their teeth after lunch (p<.001), 1.43 times higher among those who used dental floss (p<.001), 1.24 times higher among those who used mouthwash (p=.040), and 1.37 times higher was among those who had not experienced dental treatment (p=.040), which were statistically significant differences. Conclusion : This study found that when an individual's health status is maintained, positive oral health behavior can be achieved by paying attention to oral health, and this appears to contribute to improving oral health.
Background: Third molar extraction is associated with considerable pain and discomfort, which is mostly managed with oral analgesic medication. We assessed the analgesic effect of benzydamine hydrochloride, a topical analgesic oral rinse, for controlling postoperative pain following third molar extraction. Methods: A randomized controlled trial was conducted in 40 patients divided into two groups, for extraction of fully erupted third molar. Groups A received benzydamine hydrochloride mouthwash and group B received normal saline gargle with oral ibuprofen and paracetamol. Oral ibuprofen and paracetamol was the rescue analgesic drug in group A. Patients were evaluated on the $3^{rd}$ and $7^{th}$ post-operative days (POD) for pain using the visual analogue score (VAS), trismus, total number of analgesics consumed, and satisfaction level of patients. Results: The VAS in groups A and B on POD3 and POD7 was $4.55{\pm}2.54$ and $3.95{\pm}1.8$, and $1.2{\pm}1.64$ and $0.95{\pm}1.14$, respectively and was statistically insignificant. The number of analgesics consumed in groups A and B on POD3 ($5.25{\pm}2.22$ and $6.05{\pm}2.43$) was not statistically different from that consumed on POD7 ($9.15{\pm}5.93$ and $10.65{\pm}6.46$). The p values for trismus on POD3 and POD7 were 0.609 and 0.490, respectively and those for patient satisfaction level on POD3 and POD7 were 0.283 and 0.217, respectively. Conclusions: Benzydamine hydrochloride oral rinses do not significantly reduce intake of oral analgesics and are inadequate for pain relief following mandibular third molar extraction.

Objectives: This study was conducted to examine the subjects' oral health status and changes in the oral environment after mouthwash with effervescent Vitamin C and its intake and to understand the impact on changes in the number of bacteria causing periodontal diseases in the oral cavity based on the oral health status and oral environmental condition. Methods: After obtaining approval from the Institutional Review Board of D-University, 45 people (24 in an experimental group and 21 in a control group) who participated in the oral health program were selected, among visitors of the Clinical Dental Hygienics Laboratory of D. University in B. Results: Based on the subjects' periodontal health status, the number of bacteria causing periodontal diseases in the oral cavity decreased in both experimental and control groups before and after the experiment. However, in the experimental group, it was significant when the Bleeding on Probing(BOP) level was below average, and Calculus index(CAL) was above average, in Aggregatibacter actinomycetemcomitans and the red complex. It was also significant when CAL was above average in the orange complex in the control group. Regarding bacterial changes in periodontal diseases based on the subjects' oral environmental condition, there was a significant change in the Adenosine Tri Phosphate (ATP : intraoral contaminants test) test in the oral cavity in A. actinomycetemcomitans and the red complex in the experimental group and in the O'Leary index in the control group. Further, there was a significant change in the orange complex in the ATP test in the experimental group. Conclusions: A comprehensive analysis of the results revealed that the oral health care program for dental hygiene decreased the number of bacteria causing periodontal diseases in the oral cavity in both experimental and control groups.

Introduction: The aim of the present study was to investigate the effect of mechanical irrigation in combination with mouthwash of antimicrobial agents on salivary bacterial counts. Materials and Methods: This study was performed with a randomized study employing a panel of 40 healthy volunteers (20 males and 20 females) between the age of 26 and 32 years. Volunteers were randomly put in one of four treatment groups. In the first group, 0.2 mL of non-stimulatory saliva was collected from every subjective person. Then, saliva was collected after rinsing with chlorhexidine (CHX) for 1 minute. In the second group, non-stimulatory saliva was collected, and then saliva was collected after rinsing with CHX and irrigation with saline. In the third and fourth groups, the same procedures as the first and second groups were performed with povidone iodine (PVI) instead of CHX. All of these samples were cultured for 48 hours aerobically. The reduction rates of colony-forming units (CFU) were calculated for each group. The reduction rate between each group was tested statistically using student t-test. Results: Using CHX in combination with saline irrigation showed a significant decrease of the salivary bacterial CFU when compared with only using CHX.(P<0.01) And using PVI with saline irrigation showed a little decrease of the CFU when compared with only using PVI, but there was no statistical significance.(P>0.01) Conclusion: It was concluded that the CHX or PVI used with saline irrigation made the salivary bacterial counts reduced more than when CHX or PVI was used alone as an oral antiseptic agent.
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.
This study was conducted to compare the dental plaque reduction using various mouthwashes with Quantitative Light induced Fluorescence-Digital (QLF-D). A survey on 20 students was carried out. The students who were at Shingu College. Experimental group was gargled 20 ml of Listerine during 30 seconds and 15 ml of Hexamedine during 60 seconds. Control group was gargled distilled water during 30 second. The data were analyzed with t-test using SPSS 20.0 program. The ratios of control group and experimental group were reduced. Degree of ${\Delta}R30$ and ${\Delta}R70$ Listerine group was a significant difference (p>0.05). Degree of Simple Plaque Score and ${\Delta}R30$ Hexamedine group was a significant difference (p>0.05). There was no significant difference in the distilled water gargle group (p<0.05). The result of this study has the effect of two mouthwashes reduced dental plaque. The evaluation data of this study will be used in clinical application and research about QLF-D.
By studying the status of oral health provided by caregivers working in care facilities in accordance with their oral health awareness and knowledge, this thesis sought to find a plan of development to enhance the oral health for the elderly in care facilities. A survey was carried out from the 16th of August to the 2nd of September 2016, with 200 care givers as the subjects, working in 14 long-term care facilities for elderly, located in the city of D. Frequency analysis and independent sample t-test were conducted of the collected data, using SPSS 18.0. The results of the study were as follows; for gender, female was 91.5% which was higher than that of male, and married for marital status, 50 for age, highschool for education, christian for religion were shown to be the highest. The highest number of people for daily care was 6~7. In terms of status for providing oral health and oral health awareness of caregivers, the existence of oral hygiene guideline was statistically meaningful, and in terms of the status of oral health provided and oral health knowledge, there were notable differences in storage of dentures, and usage of mouthwash(p<.05).
