  • This investigation was undertaken to determine the relationship between the amount of polymorphonuclear leukocyte(PMN) enzyme myeloperoxidase(MPO) in gingival crevicular fluid(GCF) collected from active or control site and gingival disease status described by clinical indices(gingival index, papillary bleeding index, pocket depth, periotron unit). The results were as follows : 1. MPO activity/site was greater at active sites than at control sites. 2. According to increasing the clinical parameters, MPO/sites was higher statistically (P<0. 01, P<0.05). 3. High MPO(unit/site) groups was higher statistically than low MPO(unit/site) groups in various clinical parameters. 4. Correlation coefficients between MPO(unit/site) and GI, MPO($unit/{\mu}l$ GCF) and periotron unit were 0.4782, -0.5901, respectively.

  • In this study, 110 adults aged 40 to 69 years were surveyed from April 28, 2016, to May 28, 2016 to analyze their periodontal status according to daily stress, coping methods, and oral health behavior. The collected data were analyzed using the t-test, one-way analysis of variance, and hierarchical multiple regression. Daily stress levels of all subjects were most frequent potential risk 64.5% of the subjects, the high risk 19.1% and 16.4% of the health group. Regarding stress coping methods, active methods recorded 2.46, passive methods recorded 2.32. Regarding oral health behaviors, subjects brushed an average of 2.45 times daily, for an average of 2 minutes. Futhermore, 69.1% of subjects brushed before bedtime and 89.1% practiced scaling. Regarding periodontal status, the O'Leary index was 73.45, gingivitis index was 1.30, an average of 2.83 quadrants possessed a periodontal pocket. The hierarchical multiple regression analysis identified, type of employment (${\beta}=-0.348$), scaling (${\beta}=-0.253$), and age (${\beta}=0.244$) as factors that influence the number of quadrants possessing a periodontal pocket. These results confirmed that the oral health behavior of scaling, but not stress levels of coping methods, strongly influenced periodontal status.

  • Recently epidemiologic studies have indicated that the patients with periodontitis may have increased risk of ischemic cardiovascular events, and have suggested the important roles of blood cytokines and acute reactant proteins in the systemic infection and inflammatory response. Periodontitis and coronary heart disease (CHD) may share the common risk factors and the genetic mechanism associated with interleukin(IL)-1A, B and RA genotype may be involved in the production of IL-1. This study was aimed to investigate the relationship between angiographically defined CHD and periodontitis as chronic Gram-negative bacterial infection and to determine whether the IL-1 gene polymorphism is associated in both diseases. Patients under the age of 60 who had undergone diagnostic coronary angiography were enrolled in this study. Subjects were classified as positive CHD (+CHD, n=37) with coronary artery stenosis more than 50% in at least one of major epicardial arteries, and negative CHD (-CHD, n=30) without significant stenosis. After recording the number of missing teeth, periodontal disease severity was measured by means of plaque index (PI), gingival index (GI), bleeding on probing (BOP), probing depth (PD), clinical attachment level (CAL), and radiographic bone loss around all remaining teeth. Gingival crevicular fluid (GCF) was collected from the 4 deepest periodontal pockets and assessed for cytokine ($IL-1{\beta}$, IL-6, IL-1ra, tumor necrosis $factor-{\alpha}$, and prostaglandin $E_2$). Additionally, blood CHD markers, lipid profile, and blood cytokines were analyzed. IL-1 gene cluster genotyping was performed by polymerase chain reaction and enzyme restriction using genomic DNA from buccal swab, and allele 2 frequencies of IL-1A(+4845), IL-1B(+3954), IL-B(-511), and IL-1RA(intron 2) were compared between groups. Even though there was no significant difference in the periodontal parameters between 2 groups, GCF level of $PGE_2$ was significantly higher in the +CHD group(p<0.05). Correlation analysis showed the positive relationship among PD, CAL and coronary artery stenosis(%) and blood $PGE_2$. There was also significant positive relationship between the periodontal parameters (PI, PD, CAL) and the blood CHD markers (leukocyte count, C-reactive protein, and lactic dehyrogenase). IL-1 gene genotyping showed that IL-1A(+3954) allele 2 frequency was significantly higher in the +CHD group compared with the -CHD group (15% vs. 3.3%, OR 5.118,p=0.043). These results suggested that periodontal inflammation is related to systemic blood cytokine and CHD markers, and contributes to cardiovascular disease via systemic inflammatory reaction. IL-1 gene polymorphism might have an influence on periodontal and coronary heart diseases in Korean patients.

  • In this study, 21 patients diagnosed as adult periodontitis were divided into 4 groups. One quadrant with an average of 6mm deep pocket depth was chosen from each individual - Group A inserted tetra-cycline fiber after removing supragingival calculus while group RP had calculus removal and root planning alone. Group RP+A received combination of these treatments while group C received none. Plaque index, bleeding on probing, pocket depth, attachment level, and distribution of subgingival plaque were compared and evaluated among these groups at periods of first visit, 4th week and 8th week. The results were as follows ; 1. Plaque index and bleeding on probing improved after treatment and no significant difference was found between the groups. 2. When comparing the change in pocket depth between the groups, the use of tetracycline fiber showed significant reducton in pocket depth comparable to root planing. Combined therapy of tetracycline fiber and root planing showed synergistic effect in pocket depth reduction. 3. When comparing the change in attachment level between the groups, the use of tetracycline fiber showed significant increase in clinical attachment level comparable to root planing, but no synergistic effect was found in the combined therapy. 4. When comparing the change in the motile bacteria ratio between the groups, group RP and group RP+A showed significant decrease compared with control group. 5. There were no severe adverse effects from using tetracycline fiber, except for a few patient who experienced mild discomfort. In summary, the use of local adminstration of tetracycline fiber in adjunction to mechenical treatment can be effective for adult periodontitis.

  • Purpose: The purpose of this study was to assess and compare the clinical and radiographic outcomes of guided tissue regeneration therapy for human periodontal intrabony defects using two different collagen membranes: a porous nonchemical cross-linking collagen membrane (NC) and a bilayer collagen membrane (BC). Methods: Thirty subjects were randomly assigned and divided into the following 3 groups: a test group (NC+BM), in which a NC was used with xenograft bone mineral (BM), a positive control group (BC+BM), in which a BC was used with xenograft BM, and a negative control group (BM), in which only xenograft BM was used. The following clinical measurements were taken at baseline and 3 months after surgery: plaque index, gingival index, probing pocket depth, gingival recession, and clinical attachment level. Radiographic analysis was performed at baseline, 1 week and 3 months after surgery. Results: Membrane exposure was not observed in any cases. Significant probing depth reduction, attachment-level gain and bone fill were observed for both test and control groups compared to baseline at 3 months after surgery (P<0.05). However, there were no statistically significant differences in clinical improvement and radiographic bone fill between treatment protocols (P>0.05). Conclusions: Within the limitations of this study, the results suggest that both NC and BC were comparable in terms of clinical and radiographic outcomes for the treatment of periodontal intrabony defects in human subjects.

  • Periodontal disease is one of the most common chronic inflammatory diseases in the oral cavity, and this is the leading cause of loss of teeth. Studies on the association between diet and periodontal diseases are very limited. The purpose of this study was to investigate the association between food and nutrient intakes and the prevalence of periodontitis. Subjects were 13,391 adults participating in the 2008-2010 Korea Health and Nutrition Examination Survey. Periodontitis was diagnosed by dentists using the Community Periodontal Index. Nutrient intakes were estimated by the 24-hour dietary recall. Consumption frequencies of foods were from the food frequency questionnaire. Subjects were categorized into 'smoking' or 'non-smoking' groups. Multiple logistic regression analysis was applied to determine the association between diet and periodontitis. The proportions of subjects having periodontitis were 26% in the non-smoking group and 37.5% in the smoking group. In the nonsmoking group, intakes of fruits, dairy products, green tea, energy and vitamin C were inversely associated with the prevalence of periodontitis, but fish and coffee intakes were positively associated with the prevalence of periodontitis after adjusting for covariates. In the smoking group, protein and retinol intakes were inversely associated with the prevalence of periodontitis after adjusting for covariates. These results suggest that certain food and nutrient intakes such as fruits, dairy products, green tea, vitamin C, protein, or retinol intakes may affect the prevalence of periodontitis among Korean adults. Further studies are required to confirm these findings in other research settings.

  • The aim of present study was to evaluate the influence of periodontal status of adjacent tooth and loading time to the prevalence of red complex of implant sulcus. In 97 patients, partially edentulous subjects with endosseous root-form implants were selected. All subjects were medically healthy and had not taken systemic antibiotics and professional plaque control 3 months before sampling. The number was as follows: clinically healthy implants:161, clinically unhealthy implants:22, clinically healthy adjacent teeth:73, clinically unhealthy adjacent teeth:38. All teeth and implants of each patient were examined probing depth(PD), modified sulcus bleeding index(mSBI), and modified plaque index(mPI), and samples of subgingival plaque were obtained at each site with sterile curet or fine paper points, then the plaque transferred to PBS. Obtained samples were examined for the presence of P. gingivalis, T. forsythensis, and T. denticola by the polymerase chain reaction (PCR). The relationship among clinical parameters and the colonizations by the 3 bacterial species from adjacent teeth and implants region were analyzed by student t-test (p<0.05). The results of this study were as follows: 1. mPI and mSBI of implant increased with increasing of same indices of adjacent tooth(p=0.03,0.001), but not in the PD . 2. The mPI, mBI, PD of implants was higher when red complex exist. 3. The prevalence of red complex was higher when the periodontal condition is unhealthy. 4. The prevalence of red complex of implants has no significant relation to the probing depth of adjacent tooth. 5. Prevalence of P. gingivalis, T. forsythensis of implants increased with loading time. (p=0.02,0.018) These results shows the importance of oral hygiene and supportive periodontal therapy.

  • Objectives: The purpose of this study was to compare the oral health statuses pre- and post-insurance using the $5^{th}$ and $6^{th}$ National Health and Nutrition Examination Survey data to confirm the effect of scaling insurance after a year. Methods: Data were analyzed using IBM SPSS ver. 21.0 (IBM Co., Armonk, NY, USA). The four years were integrated, and a composite sample analysis was performed. A total of 26,990 people were included in the study before applying for scaling insurance (14,343 persons) or after receiving scaling insurance (12,647 persons). A chi-squared test was performed to compare the demographic characteristics and oral health status of the subjects. The significance level of the statistical test was 0.05. Results: The proportion of patients without implants was high before the provision of scaling insurance once a year, however, the proportion of patients with one or more implants was high (p<0.05) after the provision of scaling insurance once a year. Hemorrhagic periodontal tissues and tartar formation in periodontal tissues were highly prevalent before the provision of scaling insurance once a year, however, healthy periodontal tissues and formation of periodontal pockets were highly prevalent (p<0.05) after the provision of scaling insurance once a year. The decay, missing, and filled teeth index scores were higher before the provision of scaling insurance once a year (p<0.05). Conclusions: The aforementioned results showed that scaling once a year helps prevent or treat periodontal disease. In addition, we confirmed the effect of prevention on periodontal disease and dental caries, therefore, we expect it to develop into a stable policy.
