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.

It is one of difficulties to control children who show definitely negative behavior in dental clinic. In such a case, the pharmacologic management has been used to provide quality care, minimize the extremes of disruptive behavior, promote a positive psychologic response to treatment and patient welfare and safety. Deep sedation can be defined as a controlled, pharmacologically-induced state of depressed consciousness from which the patient is not easily aroused which may be accompanied by a partial loss of protective reflexes. In this retrospective report, the sedation records of 200 pediatric dental patients of ASA Class I & II who were not successfully treated under conscious sedation were used for analysis. Most frequently used regimen of deep sedation was the co-medication of midazolam(0.3mg/kg), enflurane(1.0-2.0 vol%) and 50-70% $N_2O_2$. The average age and weight of the patients was 4.6 yr (S.D: 2.72) and 18.7kg(S.D: 6.35) respectively. The average operative time was 52 minutes and midazolam (0.1-0.2cc) was additionally administered intranasally to prolong the operative time as needed. The episodes of untoward side effects were reported during and/or after the procedure in 58 patients. Serious adverse reactions such as cyanosis or laryngospasm were even reported in 7 patients but without mortality. Deep sedation is a very effective way of completing the dental treatments for those who failed to respond well to the conscious sedation. This technique has many practical advantages over general anesthesia case but the demands for the rigid monitoring criteria limit its use in general practice setting. The continuous efforts to improve the safety of the medication and the technique are required for the benefits of the patients and parent.

Introduction: Tobacco use is a global health care problem. Repetitive exposure to nicotine produces neuroadaptation resulting in nicotine dependence. Smoking is associated with a range of diseases, causing high levels of morbidity and mortality and is one of the leading causes of preventable deaths, with more than 4.6 million smokers worldwide dying each year from smoking related illnesses. Stopping smoking has major health benefits. Quitting at any age provides both short and long term benefits. Materials and methods: 45 patients attending the outpatient department at the Oxford Dental College, Bangalore, were randomly allocated to three groups of interventions namely placebo, counseling and nicotine replacement therapy (NRT). Initially each one was assessed for carbon monoxide levels using a breath analyser (pico smokerlyser bedfont UK). They were followed up for six months and the carbon monoxide levels were again assessed using the same instrument. The paired t test was used to compare the results before and after the intervention. Results: The scores before the initiation of intervention and after treatment were compared and all three interventions were found to be statistically significant after six months. It was noticed that patients with very low or low dependence followed by high dependence had good response in the placebo group (68% and 47.6% respectively), in the counseling group maximum response was seen in the medium followed by the very low group (61% and 59% respectively), and maximum response was seen in very high followed by the very low group with NRT (78.7% and 60.5% respectively). Conclusion: The inference that can be drawn from the present study is that non-invasive, non pharmacological methods like placebo and counseling are effective in low to medium groups, and NRT is effective with higher nicotine dependence.

Purpose: The aim of the present study was to retrospectively investigate the influence of potential risk indicators on the development of peri-implant disease. Methods: Overall, 103 patients referred for implant treatment from 2000 to 2012 were randomly enrolled. The study sample consisted of 421 conventional-length (>6 mm) non-turned titanium implants that were evaluated clinically and radiographically according to preestablished clinical and patient-related parameters by a single investigator. A non-parametric Mann-Whitney U test or Kruskal-Wallis rank test and a logistic regression model were used for the statistical analysis of the recorded data at the implant level. Results: The diagnosis of peri-implant mucositis and peri-implantitis was made for 173 (41.1%) and 19 (4.5%) implants, respectively. Age (${\geq}65$ years), patient adherence (professional hygiene recalls <2/year) and the presence of plaque were associated with higher peri-implant probing-depth values and bleeding-on-probing scores. The logistic regression analysis indicated that age (P=0.001), patient adherence (P=0.03), the absence of keratinized tissue (P=0.03), implants placed in pristine bone (P=0.04), and the presence of peri-implant soft-tissue recession (P=0.000) were strongly associated with the event of peri-implantitis. Conclusions: Within the limitations of this study, patients aged ${\geq}65$ years and non-adherent subjects were more prone to develop peri-implant disease. Therefore, early diagnosis and a systematic maintenance-care program are essential for maintaining peri-implant tissue health, especially in older patients.

The aim of this study was to confirm the effectiveness of learner-centered teaching models to reduce the dental anxiety. 18 children with age of 10 at the case group and 22 children with age of 10 at the control group was completed. Children from case group were participated in learner-centered oral health education, while those from control group were participated in instructor-led oral health education. Dental Anxiety Scale (DAS) at each groups were measured before oral health education, after then, oral health education of two types at each groups were separately conducted during 1-hour, 2 times. Learner-centered oral health education adapted the systematic desensitization (Tell-Show-Do) was conducted for case groups. Instructor-led oral health education was performed by using the presentation file (PPT). The change of Dental Anxiety Scale (DAS) were compare between case and control groups to evaluate the effect of learner-centered teaching type. After oral health education, DAS of the case and control groups at the baseline were 9.61 and 11.14, respectively, and the average DAS decline of case and control groups after oral health education were 2.48 and 0.55, respectively. These findings show that a learner-centered teaching type is an effective oral health program to reduce of dental anxiety in childhood.
