Background: Oral diseases are caused by various systemic and local factors, the most closely related being the biofilm. However, the challenges involved in removing an established biofilm necessitate professional care for its removal. This study aimed to evaluate and compare the effects of professional self and professional biofilm care in healthy patients to prevent the development of periodontal diseases. Methods: Thirty-seven patients who visited the dental clinic between September 2018 and February 2019 were included in this study. Self-biofilm care was performed by routine tooth brushing and professional biofilm care was provided using the toothpick method (TPM) or the oral prophylaxis (OP) method using a rubber cup. Subgingival bacterial motility and halitosis (levels of hydrogen sulfide, $H_2S$; methyl mercaptan, $CH_3SH$; and di-methyl sulfide, $(CH_3)_2S$) were measured before, immediately after, and 5 hours after the preventive treatment in the three groups. Repeated measures analysis of variance test was performed to determine significant differences among the groups. Results: TPM was effective immediately after the prevention treatment, whereas OP was more effective after 5 hours (proximal surfaces, F=16.353, p<0.001; smooth surfaces, F=66.575, p<0.001). The three components responsible for halitosis were effectively reduced by professional biofilm care immediately after the preventive treatment; however, self-biofilm care was more effective after 5 hours ($H_2S$, F=3.564, p=0.011; $CH_3SH$, F=6.657, p<0.001; $(CH_3)_2S$, F=21.135, p<0.001). Conclusion: To prevent oral diseases, it is critical to monitor the biofilm. The dental hygienist should check the oral hygiene status and the ability of the patient to administer oral care. Professional biofilm care should be provided by assessing and treating each surface of the tooth. We hope to strengthen our professional in biofilm care through continuous clinical research.

Purpose: Implant survival rates using a bone-added osteotome sinus floor elevation (BAOSFE) procedure with simultaneous placement of a non-submerged sand blasted with large grit and acid etched (SLA) implant are well documented at sites where native bone height is less than 5 mm. This study evaluated the clinical results of non-submerged SLA Straumann implants placed at the time of the BAOSFE procedure at sites where native bone height was less than 4 mm. Changes in graft height after the BAOSFE procedure were also assessed using radiographs for 5 years after the implant procedure. Methods: The BAOSFE procedure was performed on 4 patients with atrophic posterior maxillas with simultaneous placement of 7 non-submerged SLA implants. At least 7 standardized radiographs were obtained from each patient as follows: before surgery, immediately after implant placement, 6 months after surgery, every year for the next 3 years, and after more than 5 years had passed. Clinical and radiographic examinations were performed at every visit. Radiographic changes in graft height were calculated with respect to the implant's known length and the original sinus height. Results : All implants were stable functionally, as well as clinically and radiographically, during the follow-up. Most of the radiographic reduction in the grafted bone height occurred in the first 2 years; reduction after 2 years was slight. Conclusions: The simultaneous placement of non-submerged SLA implants using the BAOSFE procedure is a feasible treatment option for patients with severe atrophic posterior maxillas. However, the grafted bone height is reduced during the healing period, and patients must be selected with care.

This aim of this study is to assess the association of between glucose level and periodontal diseases in Korea adults. The data for analysis were obtained from Korea National Health and Nutrition Examination Survey 2009. A total of 7,062 subjects who aged 19 years and above, underwent a medical and dental checkups. The prevalence of undiagnosed diabetes group was 27%, and the prevalence of impaired fasting glucose(IFG) group was 41.2%, diabetes group was 43.6% with periodontitis. IFG and diabetes had significantly higher prevalence of periodotontits compared to those having normal after adjusting confounding variables; the odds ratios were 1.35 (95% confidence interval: 1.17 to 1.55) and 1.27 (95% confidence interval: 1.02 to 1.58), respectively. This study has suggested that diabetes increases the risk of periodontal disease. Proactive, preventative dental and diabetes self care, as well as regular dental and diabetes assessment, are important management strategies for impaied fasting glucose and periodotnal health.

The aim of this study was to analyze the factors related to self-reported halitosis. This study performed a questionnaire survey, targeting at 450 adults who lived in Seoul and Gyeonggi area. Main results of this study were as followings. Relationships between socio-demographic characteristics and halitosis showed no significant difference. Relationships between subjective oral health and halitosis, the groups that were treated dental prosthesis, aware of periodontal disease and dry mouth symptoms reported more halitosis (p<0.05). The group that brushed teeth less than twice a day, did not brush teeth after having a snack, and had frequent sweet treat reported more halitosis (p<0.05). The group that more experienced limitation, discomfort, discomfort reported more halitosis (p<0.05). Based on the results derived as above, the self-reported halitosis was shown to be related to periodontal disease, dry mouth, oral hygiene care and quality of life. Therefore, it is considered that preventing periodontal disease and oral dryness as well as reinforcing the oral hygiene care will contribute to prevention of halitosis and enhancement of quality of life.

Objectives : The purpose of this study was to examine the knowledge of orthodontic patients about oral health knowledge and their actual oral hygiene care, which affected the oral hygiene of orthodontic patients. It's specifically meant to provide information on the prevention of the possible side effects of orthodontic treatment and the promotion of the oral health of orthodontic patients. Methods : This study were 227 orthodontic patients of dental clinics specialized in orthodontics. The collected data were analyzed by the statistical package SPSS WIN 18.0. Results : 1.As for Oral health knowledge, they had the best knowledge about smoking and dental checkup among the subfactors of oral health knowledge. 2. As to actual oral hygiene care, what they did best was doing toothbrushing before sleeping and what they did worst was avoiding eating food injurious to teeth. 3. They scored highest in the right toothbrushing(3.85), the use of oral hygiene supplies(3.62), the prevention of periodontal diseases(3.13) in the subfactors of actual oral hygiene care. They scored lowest in dental checkup and diet(2.99). 4. There were significant differences among the patients in oral health knowledge according to age(F=2.95, p<.05). Those who received another treatment during orthodontic treatment had a better oral health knowledge than the others who didn't, and the gap between the two was statistically significant(t=2.26, p<.05). 5. There were differences among the patients in actual health hygiene care according to gender(t=2.71, p<.01), age(F=4.40, p<.01), educational experiences about oral hygiene care(t=3.06, p<.01) and experience of receiving another treatment during orthodontic treatment(t=2.56, p<.05). 6. There was a positive correlation between oral health knowledge and oral hygiene care(r=.261, p<.001). Conclusions :The above-mentioned findings suggest that more education of diet and toothbrushing should be provided for orthodontic patients to improve their oral health care.

Periodontal disease is a chronic inflammatory disease that affects quality of life and nutrition. Several studies have demonstrated a link between periodontal disease and low bone density, and vitamin D is expected to have a beneficial effect on periodontal disease as well as on bone mineral density and anti-inflammatory effects. The purpose of this study was to identify the association between periodontal disease and vitamin D because the results are different in some studies and there is a lack of research in Korea. In this study, we conducted a multiple linear regression analysis of 8,783 subjects among 23,626 subjects who were older than 20 years of age, who had serum vitamin D levels and periodontal disease, who had three years of the National Health and Nutrition Survey that was conducted in Korea from 2012 to 2014. We examined the relationship between serum vitamin D levels and periodontal disease. Tooth loss and vitamin D levels were negatively correlated (${\beta}=-0.028$, p=0.008). In addition, the prevalence of periodontal disease was found to be higher in men younger than 50 years of age with lower vitamin D levels (Q1: 1.769 [1.125~2.782], Q2: 1.182 [0.743~1.881], Q3: 0.676 [0.400~1.881]; p=0.001). Low vitamin D levels and periodontal disease are common diseases in primary care. Vitamin D supplementation is expected to have favorable effect on periodontal disease and falls, osteoporosis, osteoarthritis, and cancer. Therefore, patients with periodontal disease may benefit from periodic vitamin D management to improve quality of life as well as to manage periodontal disease. In addition, as shown in this study, not only elderly individuals, but also men younger than 50 years of age are related to periodontal disease, so there should be interest in controlling the levels of vitamin D in adults.
