Desquamative gingivitis (DG) is a gingival manifestation of systemic mucocutaneous disorders such as mucous membrane pemphigoid, oral lichen planus, and pemphigus vulgaris. The lesion is very painful, so affects the patient's ability to do proper oral hygiene practices. This may be a potential risk factor for long-term periodontal health. However, there is some controversy about the relationship between the existence of DG and periodontal status. Although the correlation between DG-associated diseases and periodontal status is not to be certain, early diagnosis and appropriate treatment including adequate plaque control and removal of local factors is very important for preventing the progression of diseases and destruction of periodontal tissues.

Purpose: The aim of this study was to investigate the risk of periodontitis according to current smoking status based on the number of cigarettes smoked per day (CPD) and the Fagerström Test for Nicotine Dependence (FTND). Methods: All enrolled patients were diagnosed and classified according to the new periodontal classification scheme, and current smoking status was investigated via a self-reported questionnaire. The correlation between smoking status (CPD and FTND) and periodontitis risk (severity of periodontitis and tooth loss due to periodontal reasons) was statistically assessed using Spearman correlation coefficients. Moreover, partial correlation analyses between smoking and periodontal status were performed after adjusting for age, sex, and diabetes mellitus. Results: Overall, data from 74 men and 16 women (mean age: 48.1±10.8 years) were evaluated. The mean number of missing teeth, CPD, and FTND score were 3.5±5.2, 24.6±15.5, and 3.5±2, respectively. CPD and the FTND were significantly positively correlated with each other (r=0.741, P<0.001). CPD and the FTND were also significantly correlated with the severity of periodontitis (CPD: r=0.457, P<0.05 and FTND: r=0.326, P<0.05) and the number of missing teeth due to periodontal reasons (CPD: r=0.525, P<0.05 and FTND: r=0.480, P<0.05), respectively. Conclusions: Within the limitations of this study, both CPD and the FTND were significantly correlated with the severity of periodontitis and the number of periodontally compromised extracted teeth.

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.

The purpose of this study was to investigate the relationship between cardiovascular disease and periodontal disease. The subjects were 3,149 adults over 40 years of age using the third year National Health and Nutrition Examination Survey (2015). Data were analyzed using the SPSS 22.0 program. As a result, the relationship between cardiovascular disease and periodontal disease was 1.27 times higher in obesity group compared to normal group, when adjusted for disturbance variables (age, smoking status, drinking status, income) In hypertensive patients, the hypertension group had a 1.32-fold higher risk of periodontal disease when the disturbance variables (age, smoking status, drinking status, income) were adjusted compared to those without hypertension. Therefore, cardiovascular disease is associated with periodontal disease, and it can be used as a good basis for educational and preventive measures to reduce or prevent the incidence of cardiovascular disease and periodontal disease in the future.

The aim of this study was to investigate the thickness of alveolar lamina dura and alveolar bone height by the change of periodontal status. The periapical radiograms of the 853 cases were taken by paralleling technique. The conclusions from this study were as follows: 1. In the normal periodontal status, the alveolar lamina dura was the thickest at alveolar crest, followed by apex, midroot, and the average thickness of the posterior teeth was thicker than that of the anterior teeth. 2. In Russel's Periodontal Index 0 and 1, no significant differences of thickness were found to be 3 areas. In Russel's Periodontal Index 2 and 6, the thickness of alveolar lamina dura at alveolar crest was decreased, only. 3. In Russel's Periodontal Index 0 and 1, distance from the cemento-enamel junction to the alveolar crest was within 1.5㎜. In Russel's Periodontal Index 2 and 6, the distance was 3. increased over 1.5㎜.

The present study examines the effects of orthodontic treatment of surgically exposed impacted upper canines or ectopically erupted upper canines to periodontal condition and whether various opening procedures have significant difference in postoperative periodontal status. The subjects included 23 orthodontic patients(7 men, 16 women) with unilateral upper canine impaction treated either with closed eruption technique(group I), with apically positioned flap procedure (group II), and those with canines ectopically erupted through keratinized gingiva (group III). In each subject, the ectopic canine was orthodontically aligned, and changes in periodontal tissue were assessed by measuring keratinized gingival width, attached gingival width, probing depth and bone probing depth. In all three groups, the width of keratinized gingiva was preserved while showed no signs of detrimental periodontal condition such as gingival recession. In all three groups, no significant difference in periodontal pocket depth from control was observed. The width of attached gingiva was significantly greater in patients treated with apically positioned flap procedure(group II) than in patients on other groups.

The purpose of this study was to determine the association between drinking behaviors and the need for periodontal treatment. The data of 5,995 adults from the 2012 Korea National Health and Nutrition Examination Survey were categorized into young adulthood (19~39 years), middle age (40~64 years), and old age (${\geq}65$ years) and analyzed. Chi-square test was performed to determine those who needed periodontal treatment by the respondents' general characteristics and drinking behaviors, and logistic regression analysis was carried out to determine the impact of each drinking behavior on the need for periodontal treatment. The results of this study have confirmed that alcohol intake is a factor adversely affecting periodontal status; therefore, patients should know the fact that excessive alcohol intake and increased frequency of drinking may affect the prevalence rate of periodontal diseases. Moreover, moderate-drinking programs that can reinforce prevention of drinking so that dental hygienists can provide good oral health care should be developed. A systematic oral health promotion program should be introduced for constant prevention with the objective of activating oral health education that focused on middle-aged and young-adult people in pursuit of healthy aging society.

This study was conducted on industrial workers to develop an integrated health promotion program on chronic disease and oral health, and to provide basic data for an effective management plan by conducting comparison analysis of periodontal health status based on the findings of hypertension and diabetes disease, and by understanding of influencing factors on periodontal health status. And the study was conducted on 4,600 workers in certain areas from March 22, 2010 to June 18, 2010. The results of the study indicates significant difference by having high plaque and gingivitis ratio in the people who had the findings of hypertension and having high plaque ratio in the people who had the findings of diabetes disease. Regarding the influences on periodontal health status, gender, age, whether the subject visited a dental hospital, whether the subject had scaling treatment, smoking, and hypertension had influenced gingivitis. And gender, age, whether the subject visited a dental hospital, whether the subject had scaling treatment, smoking, and hypertension had influenced plaque. And the aforementioned 2 groups had statistically significant difference, and the conclusion is established that metabolic syndrome which is measured during the health exam of workers is an important disease potentially threatening the health of workers and also highly related to oral health.

The purpose of this study was to obtain basic data on the relationing between smoking, drinking and periodontal pocket formation. There was no nationwide epidemiologic study on periodontal diseases and smoking, drinking in korea. 177 adults aged 20 and older were recruited the study subjects. Data for smoking, drinking and general characteristics were collected by questions. Periodontal pocket formation was measured greater than 3 mm by probing. Sectional arch numbers of periodontal pocket formation by sex, marriage status and drink yes or no were no statististically difference. Sectional arch numbers of periodontal pocket formation by ages were statististically to increase in proportion to age. Sectional arch numbers of periodontal pocket formation by economic status were statististically to increase in proportion to high economic status. Sectional arch numbers of periodontal pocket formation by smoke yes or no were statististically to increase more smokers than non-smokers. According to regression analysis, periodontal pocket formation was influenced by age, economic status and smoke yes or no.
