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.

Objectives : The purpose of this study was to examine the awareness of implant wearers about periodontal diseases and implant management, which were closely linked to implant durability, in an effort to obtain information on the right directions for oral health education related to implant self-care and specialized care. Methods : The subjects in this study were 217 patients who wore implant and visited 14 different dental hospitals and clinics in the metropolitan area. After a questioaire survey was conducted and collected data were analyed by the statistical package SPSS 18.0. Results : As for the awareness of the subjects on the regeneration of alveolar ridge by general characteristics, there were statistically significant intergroup gaps according to the number of possessed implant, implant satisfaction and subjective gingival health status(p<0.05). Regarding their awareness of implant durability by general characteristics, there were statistically significant gaps according to the number of possessed implant and oral health education experience(p<0.05). Concerning their awareness of the cycle of regular implant checkup by general characteristics, there were statistically significant gaps according to occupation, subjective gingival health status and oral health education experience(p<0.05). Conclusions : The above-mentioned findings suggest that in order to ensure the long-term safe maintenance of implant, the way of looking at periodontal diseases and implant management should be changed. Specifically, more intensive oral health education should be provided for implant wearers to be aware of the importance of self-care and specialized care to change their oral health behavior, and clinical dental hygienists should improve their role performance to make it happen.

A non-carious cervical lesion(NCCL) is the loss of tooth structure at the cementoenamel junction level that is unrelated to dental caries. This study was to evaluate the occlusal and periodontal status of teeth with non-carious cervical lesions. We evaluated 105 teeth with non-carious cervical lesions in 35 subjects aged 38-75 years and characterized them based on the shape and dimension, plaque retention, bleeding on probing(BOP), probing pocket depth(PPD), occlusal status, brushing type, hypersensitivity and wear facet. The results of this study were as follows 1. No significant association was observed between cervical lesions and occlusal contact in lateral excursions. 2. No significant difference occurred in plaque retention, PPD, BOP between teeth with and without cervical lesions. 3. Test teeth had a significantly higher percentage of hypersensitivity and occlusal wear facet than teeth without cervical lesions. 4. Wedge shaped lesions had a significantly higher percentage of plaque than saucer shaped lesions. 5. Teeth with plaque were found to have significantly deeper PPD than teeth without plaque retention in cervical regions. 6. Teeth with occlusal contacts were found to have significantly deeper PPD than teeth without occlusal contacts. 7. No significant association was observed between cervical lesions and PPD independent of plaque retention and occlusal contacts Although more knowledge is necessary, our results suggest that occlusal contact and bacterial plaque may influence on periodontal tissue, but NCCL is not directly associated with periodontal health

Objectives: The purpose of this study was to investigate the changes in factors on unmet dental scaling rate before and after the national health insurance. Methods: This study used the $2^{nd}$ data from the Community Health Survey. The study participants numbered 209,341 in 2011 and 219,517 in 2013.The average age was $51{\pm}17$ in 2011 and $52{\pm}17$ in 2013. Data were analyzed by descriptive statistics, chi -squared test and logistic regression using SPSS 23.0. Results: The scaling experienced rate of Korean adults has fallen by 3.5% from 66% to 69.5%. Logistic regression analysis showed that 2.7 times more 'people who were educated at elementary school level or lower' did not use dental scaling compared to higher educated children. Agriculture, forestry and fisheries workers did not use scaling at 2.0 times. Local residents with an income of less than one million won did not use 1.7times scaling. Local residents of 'no private insurance' did not use scaling at 1.5 times. In the case of the predisposing factors, the 20s had less than 1.8 times scaling compared to 50s. In the case of needs factor, local residents who experienced 'bad oral health status' and 'dental calculus' were treated scaling 1.3 times less compared to people with good oral health status and normal periodontal symptoms. Conclusions: In Korea, local residents are less frequently treated scaling due to enabling factors such as accessibility. In addition, predisposing factors such as age and sex, and oral health status and periodontal symptoms were related to not using the dental scaling. Therefore, the universality of health care services should be considered so that people who need periodontal care can use scaling.

Objectives: This case study was conducted to assess the changes in the oral health status of older individuals with hearing and visual impairments through home oral health care based on community care. Methods: The participants were two older adults with hearing and visual impairments. Through home visits, an oral health intervention program, including oral hygiene care and training on strengthening of oral function, was conducted once a week for 5 months. Dental hygienists performed special oral health interventions such as dental plaque control through individual tooth brushing and interdental care, training on strengthening of intraoral and extraoral muscle function, and denture care for the individuals with visual-hearing impairments. Results: The overall periodontal health status and oral muscle function improved in older adults with hearing and visual impairments. In the case of the visually impaired individuals, changes in the oral health status were oral mucosal moisture (30.1 and 37.2 points before and after intervention, respectively), salivary secretion (3.5 and 4.0 cm before and after intervention, respectively), and maximum tongue pressure (20.5 and 26.2 kPa before and after intervention, respectively). Changes in the oral health status of the hearing impaired individuals increased from 28.3 points before the intervention to 38.4 points after the intervention, and the maximum tongue pressure increased from 1.85 kPa to 23.5 kPa after the intervention. Conclusions: Oral health intervention activities contributed to improving the periodontal health and oral function of older adults with hearing and visual impairments. To improve their overall and oral health, it is necessary to prepare measures to activate customized oral health intervention programs.

Purpose: This study investigated the association between health status and tooth loss based on data from the National Health Insurance Service-Health Examinee Cohort in 2002-2015. Methods: Multivariate Cox proportional hazards regression analyses were applied to a longitudinal retrospective database, which was updated and newly released in 2018, to assess the association between health status and tooth loss while adjusting for potential confounders among sociodemographic and economic factors (sex, age, household income, insurance, and presence of disability), general and oral health status (body mass index [BMI], smoking and drinking status, periodic dental visits and scaling, and brushing before sleep), and comorbid disease (hypertension, diabetes mellitus [DM], and Charlson comorbidity index [CCI]). Results: Among 514,866 participants from a South Korean population, 234,247 (45.5%) participants satisfying the inclusion criteria were analyzed. In the adjusted multivariate analysis, sex, age, household income, insurance, presence of disability, BMI, smoking and drinking status, periodic scaling, tooth brushing before sleep, DM, and CCI showed statistically significant associations with the loss of at least 1 tooth. The risk of experiencing a loss of ${\geq}4$ teeth was associated with an increase in age (in those 50-59 years of age: hazard ratio [HR], 1.98; 95% confidence interval [CI], 1.93-2.03; in those 60-69 years of age: HR, 2.93; 95% CI, 2.85-3.02; and in those 70-79 years of age: HR, 2.93; 95%, CI 2.81-3.05), smoking (HR, 1.69; 95% CI, 1.65-1.73), and DM (HR, 1.43; 95% CI, 1.38-1.48). Conclusions: The results of this study showed that the risk of experiencing tooth loss was related to multiple determinants. DM and smoking were especially significantly associated with tooth loss.

The purpose of this study was to evaluate the bacterial adherence on e-PTFE membrane immersed in whole saliva from subjects with different periodontal status. Experiment involved 3 subject groups: 5 persons with healthy periodontium(probing depth below 3mm and no signs of gingival inflammation including bleeding on probing), 10 patients with gingivitis(probing depth below 3mm and apparent signs of gingival inflammation), and 10 patients with advanced periodontitis(probing depth over 7mm and apparent signs of gingival inflammation). Each disease group was included before and after scaling and root planing treatment. After obtaining whole saliva from each subject, e-PTFE membrane(Gore-Tex periodontal membrane : $GTPM^{(R)}$, W.L. Gore & Associates, Flagstaff, USA) specimens were immersed at room temperature in the saliva aliqouts for 1, 3, 7 days. The weight between pre - and post - immersion in saliva was measured with the analytical balance and the difference was recorded. The specimens were processed for SEM observation. The bacterial adherence on the membrane specimens was evaluated using the scanning electron microscope images. The obtained results were as follows : 1. There was no difference in the weight of bacteria adherent to e-PTFE membrane specimens according to the periodontal status and the immersion periods. 2. As the exposure time to saliva increased, the bacterial adherence to the membrane specimen significantly increased in all groups(P<0.005). 3. As the severity of periodontal disease increased, the bacterial adherence to the membrane specimens significantly increased(p<0.001). 4. After scaling and root planing, the bacterial adherence to the membrane specimens significantly decreased in gingivitis and periodontitis patient group(P<0.001). These results suggest that bacterial contamination on exposed barrier membrane surface be reduced through improvement of periodontal status and oral health environment before and after GTR procedure for the successful outcome.
