Objectives: The purpose of study is to investigate periodontal disease-related recognition and oral health-related behavior in orthodontic patients with fixed appliance. Methods: A self-reported questionnaire was completed by 286 orthodontic patients with fixed appliance in Gwangju, Jeonnam from September 1 to September 27, 2016. The questionnaire consisted of general characteristics (3 items), orthodontic related characteristics (3 items), knowledge of periodontal disease (3 items), and oral health-related behavior (4 items). The data were analyzed by frequency analysis, percentage and chi-square analysis using SPSS 21.0 program. Results: 62.8% had experiences of dental treatment and 67.5% had intention of involvement on incremental care program in orthodontic treatment periods. Accuracy rate of cause about periodontal disease was high in female and case of acquiring information experiences on periodontal disease (p<0.05). 67.2% performed correct toothbrushing for the management of periodontal disease in the experiences of acquiring information on periodontal disease in orthodontic treatment periods (p<0.05). The proportions of using interdental toothbrush and mouth rinsing solutions were high among those over 20 years old and students in the subjects (p<0.05). Conclusions:The accuracy rate were high in the answers about cause and management of periodontal disease in case of acquiring information experiences on periodontal disease in orthodontic treatment periods. Therefore, there is a need to further development and implementation of dental hygiene intervention program for periodontal disease care with fixed orthodontic appliances in that regard.

During the past decade, the use of osseointegrated implants as a foundation for prosthetic replacement of missing teeth has become highly predictable and successful. SPT(Supportive Periodontal Therapy) identified as regular visits to the therapist for periodontal control and maintenance in a well-organized scheme, the number of appointments per year following a pre-designed subject-tooth/implant-site risk assessment method. Peri-implant disease was a frequent finding in subjects having natural healthy dentition and in subjects without periodontitis. Supportive periodontal program were found to be strongly related to implant survival. This study demonstrates that regular maintenance reduces the risk for peri-implant inflammation significantly as compared with irregular maintenance. This underlines the value of the SPT in enhancing the long-term outcomes of implant therapy, particularly in subjects affected by periodontitis, in order to control reinfection and limit biological complications. It is highly recommended to maintain implant patients under a strict supportive periodontal treatment protocol that might contribute to implant survival, and regular maintenance reduces the risk for periimplant inflammation significantly as compared with irregular maintenance. Ideally, patients may be informed on the beneficial effect of a regular patient-related post-therapy care before implant insertion.

Purpose : Preeclampsia(PE) is a pregnancy-specific disease which is characterized by hypertension and proteinuria. This disease occurs in about 2-8 % of pregnancies in developing countries and remains among the major causes of maternal and neonatal mortality and morbidity throughout the world. Although the causes of PE are not fully understood, the infection has been considered as the main risk factor for this diseases. Periodontal disease may provide a chronic burden of endotoxin and inflammatory cytokines and the disease has been considered as risk factors of systemic illnesses including cardiovascular disease, atherosclerosis, and cerebrovascular ischemia. So, studies performed over the last 15 years have suggested that periodontal disease may be associated with adverse pregnancy outcomes such as PE. However, this association has not been found in all populations. The aim of this review article was to evaluate whether periodontal status and the presence of specific periodontal pathogens may influence the incidence of PE. Methods : Many research articles searched at the electronic databases(MEDLINE; 2000 to July 2017) including search term as periodontal disease and preeclampsia. Result : There were 10 case-control studies and 5 cohort studies meeting our inclusion criteria. The results showed that maternal periodontitis (adjusted odds ratio: 1.5 to 9.3) was associated with preeclampsia in 15 epidemiological studies. Conclusion : It is clear that maternal periodontitis is a risk factor associated with preeclampsia, emphasizing the importance of periodontal care in prenatal programs.

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.

Purpose: This study aimed to evaluate the effects of a policy change to expand Korean National Health Insurance (KNHI) benefit coverage to include scaling on access to dental care at the national level. Methods: A nationally representative sample of 12,794 adults aged 20 to 64 years from Korea National Health and Nutritional Examination Survey (2010-2014) was analyzed. To examine the effect of the policy on the outcomes of interest (unmet dental care needs and preventive dental care utilization in the past year), an estimates-based probit model was used, incorporating marginal effects with a complex sampling structure. The effect of the policy on individuals depending on their income and education level was also assessed. Results: Adjusting for potential covariates, the probability of having unmet needs for dental care decreased by 6.1% and preventative dental care utilization increased by 14% in the post-policy period compared to those in the pre-policy period (2010, 2012). High income and higher education levels were associated with fewer unmet dental care needs and more preventive dental visits. Conclusions: The expansion of coverage to include scaling demonstrated to have a significant association with decreasing unmet dental care needs and increasing preventive dental care utilization. However, the policy disproportionately benefited certain groups, in contrast with the objective of the policy to benefit all participants in the KNHI system.

Purpose: This study utilized a strong quasi-experimental design to test the hypothesis that the implementation of a policy to expand dental care services resulted in an increase in the usage of dental outpatient services. Methods: A total of 45,650,000 subjects with diagnoses of gingivitis or advanced periodontitis who received dental scaling were selected and examined, utilizing National Health Insurance claims data from July 2010 through November 2015. We performed a segmented regression analysis of the interrupted time-series to analyze the time-series trend in dental costs before and after the policy implementation, and assessed immediate changes in dental costs. Results: After the policy change was implemented, a statistically significant 18% increase occurred in the observed total dental cost per patient, after adjustment for age, sex, and residence area. In addition, the dental costs of outpatient gingivitis treatment increased immediately by almost 47%, compared with a 15% increase in treatment costs for advanced periodontitis outpatients. This policy effect appears to be sustainable. Conclusions: The introduction of the new policy positively impacted the immediate and long-term outpatient utilization of dental scaling treatment in South Korea. While the policy was intended to entice patients to prevent periodontal disease, thus benefiting the insurance system, our results showed that the policy also increased treatment accessibility for potential periodontal disease patients and may improve long-term periodontal health in the South Korean population.
