    In-Young Chon | Eun-Ji Yu | Sang-Cheol Yu and 3other persons | 2018, 18(1) | pp.9~18 | number of Cited : 1
    Abstract PDF
    Objectives: Pleurotus eryngii is used both for edible and medicinal purposes, and has a physiological activity. The purpose of this study is to investigate the antibacterial effect of Pleurotus eryngii against six oral pathogens (Staphylococcus aureus, Streptococcus criceti, Streptococcus mutans, Streptococcus ratti, Streptococcus sobrinus, and Actinomyces viscosus). Methods: The antibacterial activities of various extracts of Pleurotus eryngii were examined by disc diffusion assay and minimum inhibitory concentration(MIC). The disc diffusion assay was performed by putting a paper disc soaked in extracts on plates inoculated bacterial cultures. The MIC of these extracts was determined by using a broth microdilution assay at a concentration ranging between 0.03 mg/ml to 15.00 mg/ml. The growth inhibition effect of extracts was measured at 600 nm for 24 hrs. Results: The antibacterial activity was confirmed against all six tested bacteria at Pleurotus eryngii ethyl acetate extract by the disc diffusion method. Acetone extract showed the antibacterial activity only against 4 strains containing Streptococcus criceti, Streptococcus mutans, Streptococcus ratti, and Actinomyces viscosus. In ethanol extract, no activity was observed against other strains except Staphylococcus aureus. MIC values of ethyl acetate extract were the same, 7.50 mg/ml in all tested bacteria. Conclusions: Pleurotus eryngii exhibited the antibacterial activity against oral pathogens (Staphylococcus aureus, Streptococcus criceti, Streptococcus mutans, Streptococcus ratti, Streptococcus sobrinus, and Actinomyces viscosus). Thus, Pleurotus eryngii may be considered as a natural antibacterial agent for treatment of dental diseases.

    Yoon Hyun Seo | Kim Hye-Jin | 2018, 18(1) | pp.19~29 | number of Cited : 3
    Abstract PDF
    Objectives: Despite a rise of an interest in tooth whitening, diverse problems are being caused in case of hydrogen peroxide that is being used as a tooth bleaching agent. Thus, the aim was to examine tooth whitening effectiveness using natural products as a plan for supplementing this. Methods: As a result of having measured a tooth color through using VITA Easyshade V after having developed toothpaste with the application of extracts such as Citrus Peels, Mulberry (Morus alba L.) Root Bark, strawberry, and lemon, and then having used it for 10 weeks, they are as follows. Both upper and lower 6 anteriors mostly got brighter. Results: A statistically significant difference was shown especially in the right canine (p=0.015), in the right central incisor (p=0.007), and in the left central incisor (p<0.001). In consequence of having measured a color change, the tooth got brighter gradually in the higher extract content and in the lengthier use time. In case of canine, it got less bright compared to other teeth. In the outcome of evaluating sensuality, most of the questions were indicated to be high in case of using a whitening toothpaste for 10 weeks. But in what “there is no stickiness in the mouth, the stickiness was more felt in the use up to 5 weeks, but was improved in 10 weeks. Conclusions: The bleaching effectiveness was proved by developing a toothpaste with the application of natural extracts. A short-term effect cannot be seen like a whitening agent of using hydrogen peroxide. But there is a continuous effect in consideration of tooth-brushing more than 3 times a day.

    Abstract PDF
    Objectives: The aims of this study were to analyze the job stress of clinical hygienists according to their positional system and to confirm its relevance. Methods: Seven hundred seventy six clinical dental hygienists participated in this survey. The questionnaire items consisted of general characteristics, working environment, and job stress. The data analysis was performed using IBM SPSS statistics ver.23.0 software. Results: Among the job stresses, the stress on the job demands was the highest with 63.4 points, and the stress on interpersonal conflict was the lowest with 34.6 points. The total score of job stress was the highest in the 26-30 year-old age group, and major stress factors in this group were job insecurity, organizational system, and lack of reward. Team members were more stressful about insufficient job control, organizational system, and lack of reward than team managers, while team managers were more likely to score interpersonal conflict. The dental hygienists in the hospitals that did not have the positional system got more stressed in the insufficient job control, organizational system, and lack of reward area. Conclusions: The presence of positional system was related to job demand, insufficient job control, organizational system, and lack of reward. Structural efforts such as establishing a proper positional system in dental clinics will be needed to control job stress in the clinical dental hygienists.

    Abstract PDF
    Objectives: This study aims to contribute to the prevention of dental diseases and health care in the elderly by investigating the relationship among the experiences of chronic diseases, dental health status, and the behaviors in the Korean elderly people. Methods: A total of 2,856 elderly people aged 65 or older were selected as the final analysis subjects using data from the 6th National Health and Nutrition Examination Survey (2013-2014). Chronic diseases were defined as ‘cardiocerebrovascular diseases’, ‘diabetes’, ‘chronic respiratory diseases’, and ‘cancer’ diagnosed by the doctors. For the statistical analysis, SPSS 21.0 for Windows was used. Descriptive analysis and a Chi-square test were conducted to investigate the relationship among the experiences of chronic diseases, general characteristics, dental health status, and the behaviors in the Korean elderly. Finally, logistic regression analysis was performed to investigate the relationship among the experiences of chronic diseases, dental health status, and the behaviors. Results: The prevalence of Cardiocerebrovascular diseases was significantly higher in the 3-4 group of community periodontal index with the score of 1.36 (95% CI 1.03-1.00) than in the 0-2 group. The prevalence of Cardiocerebrovascular diseases was significantly higher in the group without dental examination during the past one year with the score of 1.29 (95% CI 1.00-1.66). The prevalence of diabetes was significantly higher in the uncomfortable speaking state group with the score 1.46 (95% CI 1.12-1.91). The prevalence of cancer was significantly higher in the partial denture needs group with the score 1.67 (95% CI 0.98-2.83). Conclusions: Regular dental examinations and dental health care for the elderly with chronic diseases showed that periodontal health and residual teeth could be maintained and managed. Therefore, continuous customized dental health services should be implemented for the elderly with chronic diseases.

    Abstract PDF
    Objectives: The purpose of this study was to review depression and anxiety associated with pain during scaling procedures, and to establish measures for reducing scaling pain encompassing not only physical factors but also psychological aspects of patients. This study also attempts to reduce anxiety through proper patient education prior to scaling procedures. Methods: In Seoul, and Gyeonggi area from July 26, 2017 to August 19, 2017, there were 327 copies of questionnaire data collected, excluding 23 questionnaires with insufficient information such as missing entries. The following inductions were made based on data collected. Results: There are positive correlations between pain and depression, dental anxiety, trait anxiety, and state anxiety. Especially, stronger correlation is present between pain and dental anxiety. Depression (β=0.439, p<0.001) is the most influential factor associated with pain. Next is dental anxiety (β=0.292, p<0.001). Higher the depression and dental anxiety tend to increase pain over scaling procedure. This model is with adjusted explanatory power of 28.2%. Conclusions: The result demonstrates that there is a correlation between scaling pain and depression, dental anxiety, trait anxiety, and state anxiety. Especially, depression and dental anxiety were prominent factors in affecting scaling pain. Therefore, considering aforementionedfindings, a dental hygienist's positive attitude may help in reducing the pain of the patient during scaling procedures, by affecting the psychological state of the patient and reduce the anxiety through proper education prior to scaling procedures.

    Abstract PDF
    Objectives: The purpose of this study was to investigate the correlation between soft drink consumption and subjective oral symptoms in Korean adolescents. Methods: Data of 65,528 adolescents were derived from the twelfth Korea youth risk behavior web-based survey, which was conducted from 1st June 2016 to 30th June 2016. Sociodemographic factors, dietary habit, and oral health behavior were collected as independent variables. The subjective oral symptoms were used as a dependent variable. The chi-square test and logistic regression analysis were performed to identify the correlation between dental caries and the other variables. Results: A multiple logistic regression analysis revealed that subjective oral symptoms were correlated with sex, age, subjective economic status, soft drink consumption, sweet drink consumption, tooth brushing frequency and dental sealant experience. Conclusions: Since the intake of soft drink adversely effects subjectively perceived oral symptoms in Korean adolescents, oral health education should include information on the pH levels of food and beverages including carbonated drinks, the effects of sugar on the teeth, and precautions to preventing tooth damage.
