  • Periodontal surgery can be directed to remove the irritants from the tooth surface and reduce the periodontal pocket. The purpose of this study is to compare the clinical effects after between modified Widman flap and modified flap in periodontal patients. Ninety six molar area teeth of 9 patients were used. One of sextants performed a modified Widman flap, while the other side performed a modified flap. After initial periodontal therapy, the following measurements prior to surgery(baseline) were taken : pocket depth, gingival recession, clinical attachment level, tooth mobility, bleeding on probing. Also these measurements were taken at 4 weeks, 8weeks, and 12 weeks after surgery. Significant decrease of pocket depth was shown in both techniques, and the degree of decrease was significant in modified flap than modified Widman flap at 12 weeks. Significant increase of gingival recession was shown in both techniques, and the degree of increase was significant in modified Widman flap than modified flap at 4 weeks, 8 weeks, and 12 weeks. Significant attachment gain was shown in both techniques, and the degree of increase was significant in modified flap than modified Widman flap at 4 weeks, 8 weeks, and 12 weeks. Significant increase of tooth mobility was shown in both techniques at 4 weeks, but the decrease of tooth mobility was shown at 12 weeks. Greater decrease of bleeding on probing was shown in both techniques at 4 weeks. Modified flap was better than modified Widman flap in the decrease of gingival recession and the attachment gain. These results indicate that modified flap operation is better than modified Widman flap operation in the effect of periodontal treatment.

  • The purpose of this study was to assess the recolonization of the subgingival microflora following scaling and root planing on single and multiroot teeth with periodontal pockets which were above 5mm. 7 patients with deep pockets were selected for this study. They had not taken antibiotics for 6 months and no history of dental treatment for 6 months before the study. After initial clinical(plaque index, gingival index, probing pocket depth), microbiological and BANA test were determined, each subject received a single session of scaling and root planing, but they were not received oral hygiene instructions. Clinical indices, microbial parameters and BANA test were reassessed 1, 2, and 4 weeks after treatment. The results were as follows : 1. Plaue index, gingival index and pocket depth were not significantly when compared single root group with multiroot group, both groups were siginficantly reduced at 2weeks in plaque index and 2, 4 weeks in gingival index(P<0.05), probing pocket depth was siginificantly changed at 2, 4weeks in multiroot teeth group and 4 weeks in single root teeth group(P<0.05). 2. Percentage of cocci was significantly increased at 4weeks in single root teeth group(P<0.05), motile rod was significantly changed at 4weeks in both group(P<0.05), spirochetes and nonmotile rods were not significantly changed. 3. BANA test was significantly reduced at 1 and 2 weeks (P<0.05) in single root teeth group, multiroot teeth group was not significantly all weeks. This results were suggested that clinical and microbiological effect following scaling and root planing on periodontal disease.

  • Purpose: The aim of this study was to evaluate clinical and radiographic changes and the survival rate after periodontal surgery using deproteinized bovine bone mineral (DBBM) with 10% collagen or DBBM with a collagen membrane in endo-periodontal lesions. Methods: A total of 52 cases (41 patients) with at least 5 years of follow-up were included in this study. After scaling and root planing with or without endodontic treatment, periodontal regenerative procedures with DBBM with 10% collagen alone or DBBM with a collagen membrane were performed, yielding the DBBM + 10% collagen and DBBM + collagen membrane groups, respectively. Changes in clinical parameters including the plaque index, bleeding on probing, probing pocket depth, gingival recession, relative clinical attachment level, mobility, and radiographic bone gains were evaluated immediately before periodontal surgical procedures and at a 12-month follow-up. Results: At the 12-month follow-up after regenerative procedures, improvements in clinical parameters and radiographic bone gains were observed in both treatment groups. The DBBM + 10% collagen group showed greater probing pocket depth reduction ($4.52{\pm}1.06mm$) than the DBBM + collagen membrane group ($4.04{\pm}0.82mm$). However, there were no significant differences between the groups. Additionally, the radiographic bone gain in the DBBM + 10% collagen group ($5.15{\pm}1.54mm$) was comparable to that of the DBBM + collagen membrane group ($5.35{\pm}1.84mm$). The 5-year survival rate of the teeth with endo-periodontal lesions after periodontal regenerative procedures was 92.31%. Conclusions: This study showed that regenerative procedures using DBBM with 10% collagen alone improved the clinical attachment level and radiographic bone level in endo-periodontal lesions. Successful maintenance of the results after regenerative procedures in endo-periodontal lesions can be obtained by repeated oral hygiene education within strict supportive periodontal treatment.

  • Bone graft and guided tissue regeneration have been used for the regeneration of periodontal tissue which is the ultimate goal of periodontal treatment. Recently, it was reported that some kind of growth factors were used for regeneration. Platelet rich plasma was researched that it could increase the density of bone and the rate of bone regeneration. For that, 25 patients which have pocket depth more than 5mm at any of 6 surfaces, of healthy patient without any systemic disease were treated. $Biogran^{?}$ Were grafted into 14 infrabony pockets as controls, and $Biogran^{(R)}$ with PRP were inserted into 31 infrabony pockets. And then, follwing evaluations were made at the end of 1, 3 and 6 months. 1. There was no statistical difference between control and experimental group in pocket depth, gingival recession, minimum probing attachment level and maximum probing attachment level at preoperation(p>0.05). 2. Decrease in probing pocket depth were reduced to 3.32mm for experimental group and 2.71mm for control group. The decrease was evident at the end of 1 month, they were 2.97mm and 2.29mm,and it was statistically difference(p<0.05). 3. Gingival recession was increased by 0.55mm in experimental group and 0.50mm in control group, it was evident at the end of 1 month. And it was statistically difference(p<0.05). 4. Minimum probing attachment level was increased by 0.35mm in experimental group and 0.36mm in control group, it was statistically difference(p<0.05). 5. Maximum probing attachment level was decreased by 3.19mm in experimental group and 2.93mm in control group, it was statistically difference(p<0.05). 6. There was no statistical difference between control and experimental group in pocket depth, gingival recession, minimum probing attachment level and maximum probing attachment level(p>0.05). There was statistical difference in decrease of pocket depth between pre-operation and 1 month after post-operation(p<0.05). In conclusion, bone graft using $Biogran^{?}$ and bone graft using $Biogran^{?}$ With platelet rich plasma were both effective in treatment of infrabony pocket, bone graft using $Biogran^{?}$ With platelet rich plasma was more effective in early soft tissue healing.

  • The purpose of this study was to make and ascertain a decision making process on the base of patient-oriented utilitarianism in the treatment of patients of chronic adult periodontitis. Fifty subjects were chosen in Yonsei Dental hospital and the other fifty were chosen in Severance dental hospital according to the selection criteria. Fifty four patients agreed in this study. NS group(N=32) was treated with scaling and root planing without any surgical intervention, the other S group(N=22) done with flap operation. During the active treatment and healing time, all patients of both groups were educated about the importance of oral hygiene and controlled every visit to the hospital. When periodontal treatment needed according to the diagnostic results, some patients were subjected to professional tooth cleaning and scaling once every 3 months according to an individually designed oral hygienic protocol. Probing depth was recorded on baseline and 18 months after treatments. A questionnaire composed of 6 kinds(hygienic easiness, hypersensitivity, post treatment comfort, complication, functional comfort, compliance) of questions was delivered to each patient to obtain the subjective evaluation regarding the results of therapy. The decision tree for the treatment of adult periodontal disease was made on the result of 2 kinds of periodontal treatment and patient's ubjective evaluation. The optimal path was calculated by using the success rate of the results as the probability and utility according to relative value and the economic value in the insurance system. The success rate to achieve the diagnostic goal of periodontal treatment as the remaining pocket depth less than 3mm and without BOP was $0.83{\pm}0.12$ by non surgical treatment and $0.82{\pm}0.14$ by surgical treatment without any statistically significant difference. The moderate success rate of more than 4mm probing pocket depth were 0.17 together. The utilities of non-surgical treatment results were 100 for a result with less than 3mm probing pocket depth, 80 for the other results with more than 4mm probing pocket depth, 0 for the extraction. Those of surgical treatment results were the same except 75 for the results with more than 4mm. The pooling results of subjective evaluation by using a questionnaire were 60% for satisfaction level and 40% for no satisfaction level in the patient group receiving nonsurgical treatment and 33% and 67% in the other group receiving surgical treatment. The utilities for 4 satisfaction levels were 100, 75, 60, 50 on the base of that the patient would express the satisfaction level with normal distribution. The optimal path of periodontal treatment was rolled back by timing the utility on terminal node and the success rate, the distributed ratio of patient's satisfaction level. Both results of the calculation was non surgical treatment. Therefore, it can be said that non-surgical treatment may be the optimal path for this decision tree of treatment protocol if the goal of the periodontal treatment is to achieve the remaining probing pocket depth of less than 3mm for adult chronic periodontitis and if the utilitarian philosophy to maximise the expected utility for the patients is advocated.

  • The ultimate goal of periodontal treatment is to regenerate the lost periodontal apparatus. Many studies were performed in developing an ideal bone substitute. Anorganic bovine-derived xenograft is one of the bone substitute, which were studied and have been shown successful for decades. The aim of this study is to evaluate the effect anorganic bovine-derived xenograft. Total of 20 patients, with 10 patients receiving only modified widman flap, and the other 10 receiving anorganic bovine-derived xenograft and flap surgery, were included in the study. Clinical parameters were recorded before surgery and after 6 months. The results are as follows: 1. The test group treated with anorganic bovine-derived xenograft showed reduction in periodontal pocket depth and clinical attachment level with statistically significance(p<0.001) after 6 months. The control group treated with only modified Widman flap showed reduction only in periodontal pocket depth with statistically significance(p<0.001) after 6 months. 2. Although periodontal probing depth change during 6 months did not show any significant differences between the test group and the control group, clinical attachment level gain and re-cession change showed significant differences between the two groups(p<0.05). On the basis of these results, anorganic bovine-derived xenograft improves probing depth and clinical attachment level in periodontal intrabony defects. Anorganic bovine-derived xenograft could be a predictable bone substitute in clinical use.

  • The efficacy of air-polishing on subgingival debridement, as compared to scaling and root planning (SRP), was evaluated clinically and microbiologically. Fifteen patients diagnosed as chronic periodontitis, and having single-root tooth over 5 mm of pocket depth symmetrically in the left and right quadrant, were investigated. Subgingival debridement was performed by SRP and air-polishing. The results were evaluated and compared clinically and microbiologically. Probing pocket depth (PPD), bleeding on probing (BOP), relative attachment level (RAL) and change of gingival crevicular fluid (GCF) were assessed before treatment, and at 14 and 60 days after treatment. Microbial analysis was done pre-treatment, post-treatment, and at 14 and 60 days after treatment. Results of air polishing showed that post treatment, the PPD and BOP decreased, and attachment gain was observed. There was no clinical difference when compared to SRP. The volume of GCF decreased at 14 days, and increased again at 60 days. Compared to SRP, there was a statistical significance of the volume of GCF at 60 days in air-polishing. In the microbial analysis, high-risk bacteria that cause periodontal disease were remarkably reduced. They decreased immediately after treatment, but increased again with the passage of time. Thus, our results show that subgingival debridement by air-polishing was effective for decrease of pocket depth, attachment gain, decrease of GCF and inhibition of pathogens. Further studies are required to compare air-polishing and SRP, considering factors such as degree of pocket depth and calculus existence.
