Objectives: The objective of the study was to investigate oral health index between adequate and inadequate dental care following preventive scaling in regular dental check-up and management. Methods: The subjects in Busan were assigned to two groups including inadequate dental care (140 patients) and adequate dental care (88 patients) after preventive scaling from January 2014 to June 2015. The study instruments included oral health knowledge, awareness, practice, and community periodontal index of treatment needs (CPITN). Results: CPITN was significantly different between the two groups (p<0.05). Positive correlations were found in oral heath knowledge and awareness (r=0.462, p<0.05) before application of preventive scaling. There was a close correlation in oral health awareness and practice (r=0.205, p<0.05) before application of preventive scaling. After application of preventive scaling, oral health knowledge and awareness showed positive correlation (r=0.643, p<0.05). After application of preventive scaling, there was also a close correlation between oral health knowledge and practice (r=0.453, p<0.05). Oral health awareness and practice (r=0.512, p<0.05) showed positive correlation after the application of preventive scaling. However, oral health practice and CPITN (r=-0.189, p<0.05) showed a negative correlation. Conclusions: Practice made periodontal condition improve. To promote oral health practice in the group without adequate dental care, it is necessary to pay attention to adequate dental care and preventive scaling through education by dental hygienists.
The purpose of the present investigation was to compare the effectiveness of porous hydroxyapatite (PHA) and coralline based porous calcium carbonate(PCC) as implant materials in human periodontal osseous defects. 10 adult patients having periodontitis and 2 similar angular osseous defects ${\ge}$5mm as verified by radiographic analysis and clinical probing depth ${\ge}$4mm were selected. The measurements were recorded just before surgery and after 6 month. Clinical parameters used in this study included gingival recession, pocket depth, probing attachment level, Sulcus Bleeding Index, Plaque Index, tooth mobility and bone defect depth measurements. After initial therapy, patients were treated with mucoperiosteal flap surgery. The contralateral bony defects in each patient randomly assigned to either bone graft material, one with PHA(Interpore 200) and the other with coralline based calcium carbonate(Biocoral). After 6 month both groups showed statistically significant reduction of pocket depth, Sulcus Bleeding Index, Plaque Index and significant improvement in probing attachment level. No statistically significant differences were found between the groups. There were 3.0mm or 68% of bone repair with PHA and 3.1mm, 61% with PCC. These values were likewise not significantly different. The data and clinical impression strongly suggest that both PHA and PCC are alloplastic implants with clinically apparent acceptance by the soft and hard tissue and that they can be used as bone graft materials successfully.
Halitosis, defined as an unpleasant oral odor, is a commonly experienced condition with a variety of etiological factors and may cause a significant social or psychological handicap to those suffering from it, In most cases, halitosis originates within the oral cavity itself and patients with periodontal disease often suffer from oral malodor, The most common cause of this disease is related to microbiota which reside on the tongue and in the periodontal pocket, This study was undertaken to examine the effect of full mouth disinfection including tongue scraping on oral malodor in a group of patients with chronic periodontitis, The relationship between halitosis and oral health status was also investigated, The volatile sulfur compounds (VSC) scores were significantly correlated with Plaque Index, Bleeding Index, pocket depth, and tongue coating score, The organoleptic ratings were significantly associated with Plaque Index, Bleeding Index. and tongue coating score, The VSC scores and organoleptic ratings correlated strongly with each other. Full mouth disinfection resulted in a significant reduction in the VSC scores. organoleptic ratings, and self-perception of malodor up to 12 weeks, This study indicates that in patients with chronic periodontitis. a full mouth disinfection including tongue scraping has a significant effect in the treatment of oral malodor.
The purpose of this study was to evaluate photothermal effect of laser, which eliminates and reduces bacteria causing periodontal disease, on treatment of periodontal disease. This study included subjects with moderate periodontitis who visited the Department of Oral Medicine, College of dentistry, Yonsei University. The subjects were divided into experimental group, where Argon laser treatment was used, and control group, where conventional subgingival curettage was used. Gingival fluids from each subject were collected prior and after 1 week of the treatment, and changes in number of bacterial colonies cultured from aerobic as well as anaerobic bacteria responsible for the periodontal disease, and changes in clinical indices related to the periodontal disease, such as plaque index, gingival index, sulcus bleeding index, were analysed. As a result, the number of bacterial colonies of aerobic and anaerobic bacteria reduced after 1 week of the treatment in both groups, especially the bacterial colonies of anaerobic bacteria which showed statistically significant reduction(p<0.1). However, there was no significant difference between the experimental group and the control group. Clinical indices including plaque index, gingival index, sulcus bleeding index were reduced after 1 week of the treatment in both groups. In the experimental group, gingival index(p<0.1) and sulcus bleeding index(p<0.01) showed significant reduction, and, in the control group, sulcus bleeding index(p<0.01) showed significant reduction. However, there were no significant differences in each indices between the two groups. The above results suggest that Argon laser could be used as a substitute of conventional subgingival curettage, or in combination with subgingival curettage which would increase the effect of the treatment. Although the possibility of clinical application of Argon laser was observed in this study, more randomized-controlled research, including acquirement of sufficient samples as well as long-termed follow up, would be necessary before clinically effective application of Argon laser.
Recent cross-sectional studies indicate that obesity is a risk factor for periodontal disease. This study was aimed to investigate whether the four-week weight control program including caloric restriction and exercise training could have an effect on periodontal health. Forty-one obese (body mass index [BMI] ${\geq}25.0$) and five overweight ($23.0{\leq}BMI<25.0$) students participated in the weight control program. Anthropometric data and oral examination data were collected at the baseline and at the 27th day. BMI, waist hip ratio (WHR), and percent of body fat (PBF) of the subjects decreased significantly, but gingival index, sites with bleeding on probing (BOP), and sites with shallow pocket depth didn't show the significant changes in paired t-test. There was no difference in the outcomes according to smoking, drinking alcohol, and sex. Nevertheless, PBF and sites with BOP (r=0.777) and WHR and sites with shallow pocket depth (r=0.444) showed positive correlations. PBF accounted for 58.9% of the variance in sites of BOP in regression analysis. We suggested that obesity might relate with periodontal health, although it was not clear whether weight control could influence on periodontal health directly.
This study was carried out in order to offer basic data available for being helpful to promoting periodontal health, by analyzing effects in socio-demographical and health-behavior characteristics on index of evaluating periodontal status. The study conducted a survey for the 151 adults aged 30 to 59 from October. 1, 2006 to March. 30, in 2007. The collected data were analyzed with t-test and one-way of variance using SPSS 12.0. Then, the following result were obtain. 1. sociodemographic and health-behavior characteristics is not related to O'Leary plaque index, Loe & Silness gingival index. 2. The number of sextants possessing periodontal pocket was higher in men(3.34) than women(2.43), also statistically significant difference in the occupational fields. Smoker(3.38) was higher than non-smoker(2.72), and it was higher over 3 times a week than almost no drinking as for frequence alcohol intake. 3. The amount of loss for inter-dental alveolar crest was higher in men(71.79) than women(42.24), was highest of the 'professional' in the occupational fields, and smoker(67.23) was higher than non-smoker(48.22). 4. There was significantly difference in the number of missing tooth between age and frequence of alcohol intake. These results that occupational fields, smoking and alcohol intake were related to the number of sextants possessing periodontal pocket and amount of loss for inter-dental alveolar crest.

Objectives : This study has made a comparison of the difference between the periodontal parameter before and after applying dental hygiene process on patients requiring supportive periodontal therapy at a private dental clinic. Methods : The entire process was conducted on 74 patients. As a result of analyzing the difference in periodontal parameters such as PPD>4mm, BOP, and O'Leary Index of 29 patients that has completed 1 circle of dental hygiene process. Results : All periodontal parameters in all subject patients had been significantly reduced(p<0.05). Furthermore, as a result of comparing the periodontal conditions of the smoking group and non-smoking group, complier and non-complier, all parameters were reduced with a significant difference in the non-smoking group and the complier, but the smoking group and the non-complier did not show difference in all parameters. As a result of making an assessment of before and after dental hygiene process according to PRA classifications, high risk group has been generally changed to moderate or low risk group. Conclusions : Accordingly, the supportive periodontal therapy applying dental hygiene process has been shown to be effective. The dental hygiene process in periodontal patients who require continuous management is anticipated to be a very efficient process.
Background: The purpose of this study was to evaluate the association between metabolic syndrome and periodontal disease in Korean adults. Methods: This study analyzed the screening data of 12,686 adults aged ≥19 years, including demographic characteristics, lifestyle habits, and each component of metabolic syndrome, obtained from the sixth Korea National Health and Nutrition Examination Survey database. Periodontal health status was measured by the community periodontal index. Subjects with three or more risk factors were considered as having metabolic syndrome. The Rao-Scott chi-square test was performed to assess the relationships between demographic characteristics, lifestyle habits, components of metabolic syndrome, and periodontal disease. Logistic regression analysis was performed based on the complex sample to evaluate the relationship between metabolic syndrome and periodontal disease. Results: The prevalence of periodontal disease was higher among the subjects with advancing age, lower average household income and education level, those working in production, residents of eup-myeon areas, in past or current smoker, those with excessive alcohol consumption habit in a week, and reduced brushing frequency and the use of oral care products (p<0.001). Each component of metabolic syndrome was associated with higher prevalence of periodontitis in the subjects with abnormal than in those with normal levels (p<0.001). The prevalence of periodontal disease in subjects with metabolic syndrome was approximately 1.443 times higher than that in normal subjects (odds ratio,1.443; p<0.001). Conclusion: This study confirmed the association between metabolic syndrome and periodontitis in Korean adults, and further studies will be needed to determine the causal relationship between the two conditions.
The purpose of this study was to investigate the effect of diabetes on periodontal disease according to oral health behavior. The date from the 2013-2015 Korean National Health and Nutrition Survey were used, and 14,282 subjects were included in the analysis. Periodontal disease was assessed using the Community Periodontal Index and using logistic regression. When all of the oral health behaviors were included in the model, tooth brushing frequency, flossing, and interdental brushing were significantly associated with periodontal disease, and periodontal disease risk was significantly higher with diabetes, but there was little difference in periodontal disease risk by input factors. Oral health behaviors were associated with periodontal disease in the normal blood glucose group but not in the presence of diabetes mellitus. If there is diabetes, it is difficult to manage periodontal disease by only the health behavior, so it is necessary to control blood sugar.
Purpose: An animal periodontitis model is essential for research on the pathogenesis and treatment of periodontal disease. In this study, we have introduced a lipopolysaccharide (LPS) of a periodontal pathogen to the alveolar bone defect of experimental animals and investigated its suitability as a periodontitis model. Methods: Alveolar bone defects were made in both sides of the mandibular third premolar region of nine beagle dogs. Then, the animals were divided into the following groups: silk ligature tied on the cervical region of tooth group, Porphyromonas gingivalis LPS (P.g. LPS)-saturated collagen with silk ligature group, and no ligature or P.g. LPS application group as the control. The plaque index and gingival index were measured at 0 and 4 weeks postoperatively. The animals were then euthanized and prepared for histologic evaluation. Results: The silk ligature group and P.g. LPS with silk ligature group showed a significantly higher plaque index at 4 weeks compared to the control (P<0.05). No significant difference was found in the plaque index between the silk ligature group and P.g. LPS with silk ligature group. The P.g. LPS with silk ligature group showed a significantly higher gingival index compared to the silk ligature group or the control at 4 weeks (P<0.05). Histologic examination presented increased inflammatory cell infiltration in the gingival tissue and alveolar bone of the P.g. LPS with silk ligature group. Conclusions: An additional P.g. LPS-saturated collagen with silk ligature ensured periodontal inflammation at 4 weeks. Therefore, P.g. LPS with silk ligature application to surgically created alveolar bone defects may be a candidate model for experimental periodontitis.
