  • This study was designed to compare the effects of treatment using chitosan membrane $(Nanogide-C^{(R)})$ resorbable barrier with control treated by polylactic acid/polylacticglycolic acid membrane(PLA/PLGA membrane, $Biomesh^{(R)}$). 44 furcation defecs from 44 patients with class 2 furcation degree were used for this study, 22 sites of them were treated by chitosan membrane as experimental group and 22 site were treated by PLA/PLGA membrane as control group. Clinical parameters including probing depth, gingival recession, attachment level and radiographic examination were evlauated at base line, 1 month, 2 month and 3 month. after surgery. Statistical test used to analyze these data included paired t-test, one way ANOVA. The results are as follows : 1. Probing depth was significanlly decreased in the two group and there were significant differences between groups(p<0.05). 2. Gingival recession was not significanlly increased in the two group and there were no significant differences between groups(p<0.05). 3. Loss of attachment was statistically decreased in the two group and there were no significant differences between groups(p<0.05). 4. Horizontal bone level was significanlly increased in the two group and there were significant differences between groups(p<0.05). On the basis of these results, chitoans resorbable membrane has similar potential to PLA/PLGA membrane in GTR for furcation defect.

  • The purpose of this study was to examine association between oral health status and perceived general health symptom. We analyzed 14,231 subjects who participated in Korea National Health and Nutrition Examination Survey (2007~2009). All individuals were examined by a questionnaire about socioeconomic history, smoking and drinking habit, the frequency of daily tooth brushing, the presence of regular dental visit, and EuroQol-5D. Dental survey was conducted to find the decayed, missing, and filled teeth (DMFT) index and community periodontal index. Subjects with perceived problem with mobility had higher DMFT index (odds ratio, 1.18, p<0.001). Subjects with with perceived problem with pain/discomfort had higher DMFT index (odds ratio, 1.16, p<0.001). Self-rating general health symptom was not associated with periodontitis (p>0.05). Perceived general health was associated with DMFT index. It is recommendable that we can use the perceived general health to predict oral health status.

  • Purpose: Fibronectin (FN) has been shown to stimulate bone regeneration in animal models. The aim of this study was to evaluate the capacity of bovine bone mineral coated with synthetic oligopeptides to enhance bone regeneration in rabbit calvarial defects. Methods: Oligopeptides including fibrin-binding sequences of FN repeats were synthesized on the basis of primary and tertiary human plasma FN structures. Peptide coated and uncoated bone minerals were implanted into 10 mm calvarial defects in New Zealand white rabbits, and the animals were sacrificed at 4 or 8 weeks after surgery. After specimens were prepared, histologic examination and histomorphometric analysis were performed. Results: At 4 weeks after surgery, the uncoated groups showed a limited amount of osteoid formation at the periphery of the defect and the oligopeptide coated groups showed more osteoid formation and new bone formation in the center of the defect as well as at the periphery. At 8 weeks, both sites showed increased new bone formation. However, the difference between the two sites had reduced. Conclusions: Fibrin-binding synthetic oligopeptide derived from FN on deproteinized bovine bone enhanced new bone formation in rabbit calvarial defects at the early healing stage. This result suggests that these oligopeptides can be beneficial in reconstructing oral and maxillofacial deformities or in regenerating osseous bone defects.

  • PURPOSE. The purpose of this case series was to evaluate the effect of guided bone regeneration using demineralized allogenic bone matrix with calcium sulfate. MATERIALS AND METHODS. Guided bone regeneration using Demineralized Allogenic Bone Matrix with Calcium Sulfate ($AlloMatrix^{TM}$, Wright. USA) was performed at the time of implant placement from February 2010 to April 2010. At the time of the second surgery, clinical evaluation of bone healing and histologic evaluation were performed. The study included 10 patients, and 23 implants were placed. The extent of bony defects around implants was determined by measuring the horizontal and vertical bone defects using a periodontal probe from the mesial, distal, buccal, and lingual sides and calculating the mean and standard deviation of these measurements. Wedge-shaped tissue samples were obtained from 3 patients and histologic examination was performed. RESULTS. In clinical evaluation, it was observed that horizontal bone defects were completely healed with new bones, and in the vertical bone defect area, 15.1% of the original defect area remained. In 3 patients, histological tests were performed, and 16.7-41.7% new bone formation was confirmed. Bone graft materials slowly underwent resorption over time. CONCLUSION. $AlloMatrix^{TM}$ is an allograft material that can be readily manipulated. It does not require the use of barrier membranes, and good bone regeneration can be achieved with time.

  • The purpose of this study was to investigate factors affecting perceived oral health status according to socioeconomic status and community periodontal index(CPI) and decayed, missing, and filled teeth(DMFT) using the 6th Korean national health and nutritional examination survey(KNHANES VI) and provide a basic data for plan of policy. The higher the age, the lower the household income and education level, the worse the subjective oral health had better oral health and there was a tendency that the respondents who had no oral exam within 1 year and experienced CPI or DMFT estimated their own health as worse. It is needed to make policy development to resolve the inequality of oral health.

  • This study aimed to examine whether needs for scaling are associated with health behaviors in a representative sample of middle-aged Korean people. We examined 5120 individuals aged 40 to 64 years who participated in the Seventh Korea National Health and Nutrition Examination Survey. Multivariate logistic regression analysis was performed with adjustments for demographic variables and health status. This analysis revealed significant associations between needs for scaling and the following: current smoking, no visits to dental clinics, current drinking, non-oral checkups, and non-use of oral care products. As a result of a subgroup analysis, significant factors differed according to gender. As a result of this study, needs for scaling were associated with identified health behaviors and findings about health behaviors that are effective for maintaining and promoting periodontal health in middle-aged people were confirmed.

  • Introduction: The aim of the current study was to describe the prevalence and treatment of mandibular first molar eruption disturbances. Methods: A total of 38 mandibular first molars(M1mn) from 36 patients(17 males and 19 females; aged 9 years 2 months?35 years 10 months) were identified from the 13,391 patients that received orthodontic treatment from 1983?2012. The subjects were classified into 3 categories based on panoramic radiographic examination: impaction due to ectopic position of the tooth germ relative to the contra-side same tooth(Group 1), impaction due to obstruction of the eruption path with cyst or calcium mass (Group 2), and primary and secondary retention due to defects in the follicle or periodontal ligament(PDL; Group 3). The treatment outcomes were evaluated into four categories: no treatment(A), orthodontic traction(B), autotransplantation(C), and extraction due to orthodontic traction failure(D). Results: The prevalence rate of M1mn eruption disturbances in this sample was 0.27%. In Groups 1 and 2, most of the impacted M1mn were erupted successfully by orthodontic traction. In Group 3, most of the retained M1mn were failed to erupt and recommended for extraction. Conclusions: Treatment prognosis was favorable on Group 1 & 2 than Group 3. After removing an element of the cause in case of Group 1 & 2, orthodontic traction or periodic observation will be recommended.

  • The socket preservation procedure was a simple and effective technique, and has better prognosis for implantation. The socket preservation usually used barrier membrane in combination with/without alloplastic bone materials. A recently study had shown that a regenerative therapy to tooth extraction utilizing growth factors made better results. Platelet-rich plasma was clinically easy method that acquired the growth factors, and is known that accelerated new bone formation and mineralization of bone graft materials. The purpose of this study was to evaluate clinical and histopathologic results which occur following socket preservations using platelet-rich plasma and bovine bone powder. Twelve patients who required extraction of one or more teeth for implantation at the department of periodontics in Dankook University Dental Hospital were selected. Extraction sockets were treated by using platelet-rich plasma and bovine bone powder. 3 months later, we observed clinical and histopathological results as follows: 1. Internal vertical measurement was an average of 7.33mm preoperatively and statistically significantly decreased to an average of 1.42mm postoperatively(p<0.05). 2. External vertical measurement was an average of 3.33mm preoperatively and decreased to an average of 2.75mm postoperatively; therefore there was no significant difference. 3. Horizontal measurement was an average of 7.75mm preoperatively and statistically decreased to an average of 6.08mm postoperatively(p<0.05). 4. Osteocyte-like cells and new bone formation connected with bovine bone grafts were observed in histopathologic examination. This study implied that platelet-rich plasma and bovine bone powder grafts were effective treatment for socket preservation and regeneration of severe bony defect made by implantation failure.

  • The purpose of this study was to analyze the responses of 5,824 adults(2,574 males and 3,250 females over the age of 19 years) using raw data from the 7th period of the National Health and Nutrition Examination Survey to investigate the relationship between systemic disease activity restriction and oral health. There were many systemic disease activity restrictions in adults with oral chewing and speaking problems, and it was statistically significant(p<.001). Factors influencing activity restriction due to systemic disease include age(odds ratio 1.03), Male(odds ratio 0.84), education level(odds ratio 0.57, 0.45, 0.31), drinking(odds ratio 1.38), chewing(odds ratio 1.86) and speaking(odds ratio 1.84) problems. There was a higher probability of activity restriction due to systemic disease when they received treatment for periodontal disease(odds ratio 1.27) and broken teeth(odds ratio 2.1). Also, it was statistically significant that the quality of life decreased when there was chewing and speaking problems.

  • Objectives: The purpose of this study was to determine the importance of oral health care in the control of diabetes mellitus. Methods: The raw data of the National Health and Nutrition Examination Survey were utilized and 4,445 adults aged 19 and over were surveyed and examined. Complex samples crosstabs and general linear model analysis were carried out. Results: In total, 69.6 percent of the subjects were normal, 21.4 percent had impaired fasting glucose, and 9.0 percent had diabetes. By sex, 25.8 percent of the men had impaired fasting glucose and 10.8 percent had diabetes. Women with impaired fasting glucose accounted for 17.2 percent and 7.2 percent of women had diabetes. Impaired fasting glucose and diabetes were more common among men. Fasting glucose values were higher in the respondents who were male, were younger, whose monthly mean household income was lower, and who were less educated. Fasting glucose values were higher when the frequency of toothbrushing was lower and when dental floss and a dental brush were not in use. Fasting glucose was lower when there was no periodontal disease, when there was less difficulty in mastication, and when there were no implants in the upper and lower jaws. Conclusions: Oral health care workers should develop a variety of programs to motivate patients to take care of their own oral health actively and responsibly.
