The present study investigate the effect of newly designed toothbrush(Chess tip : experimental group), conventional toothbrush(control group) on plaque control, gingivitis, and periodontitis. The results of 4weeks post-research by clinical comparison between the two groups are as follows. 1. In analysis of plaque index between groups there was Significant difference in the experimental group at 2,4 week. 2. In analysis of gingival index between groups there was significant difference in the experimental group at 1,2,4 week. 3. Both experimental group and control group showed decrease in periodontal pocket depth after 4week, but there was significant difference in the experimental group at 4 week. 4. Both experimental group and control group showed decrease in bleeding on probing after 4week, but there was significant difference in the experimental group at 4 week. These results indicate that newly designed toothbrush has beneficial effects as additional aid of mechanical treatment at the point of periodontal pocket, plaque control, and bleeding on probing.

이 연구의 목적은 치주질환에 이환된 성견의 치근을 활택술 후 발치와에 이식하였을 때 calcium sulfate 골이식이 치근흡수와 치근유착을 지연시키는가를 알아보고자 하는 것이다.성견의 제2, 제3 소구치 주위의 치조골을 제거하여 분지부를 노출시키고, 8주간 교정사를 결찰하여 실험적 만성치주염을 유발하였다. 치관을 제거하고, 치근을 반분하고, 활택한 후 발치하였다. 발치된 치근을 둘로 나누어 각각을 우측에는 calcium sulfate와 함께, 좌측에는 이식재 없이 이식하였다. 12주간의 치유 후 조직학적으로 관찰하였다. 대조군에서는 흠의 치관쪽으로 치근흡수와 치근유착이 일어났고, 실험군에서는 성견 결합조직과 calcium sulfate가 위치하였던 공간이 관찰 되었고 치근흡수는 지연되었다. 이 연구에 나타난 바에 의하면, 치근 이식시 calcium sulfate 의 사용은 치조골로부터의 육아조직을 배제하고 치근흡수와 치근유착을 지연할 수 있는 것으로 생각된다.

The purpose of this study was to evaluate the clinical effects of Dipotassium glycyrrhizinate, Allantoin, Hinokitiol, Cetylpyridinium chloride containing gel($Dentheth^{(R)}$) on periodontitis. 41 patients with sites having pocket depth of 4-6mm were selected for the study. We classified 2 groups which consisted of 21 patients in the test group(exp.) and 20 patients in the control(placebo) respectively. Following a baseline examination, plaque and calculus were removed and then the experimental gel were handed out to the patients and topical application regimens were initiated. During the 4-week experimental period, pocket depth, bleeding on probing, gingival index, plaque index as a clinical parameters were measured in the baseline, 2 weeks, 4 weeks respectively. A questionnaire was delivered to each patients in 2 weeks, 4 weeks respectively. The results were as follows : 1. Probing pocket depth showed a significant difference in the Exp. group compared with the control group in the changes from baseline to 2 weeks(p<0.05), but there was no significant difference between the groups in the changes from baseline to 4 weeks, from 2 weeks to 4 weeks(p<0.05). 2. The Exp. group showed a significant difference compared with the control group in the changes from baseline to 2 weeks, from baseline to 4 weeks, from 2 weeks to 4 weeks in bleeding on probing(p<0.05). 3. The gingival index showed a significant difference compared with the control group in the changes from baseline to 2 weeks, from baseline to 4 weeks, from 2 weeks to 4 weeks after 4 weeks use of a gel(p<0.05). 4. The plaque index showed a significant difference in the Exp. group compared with the control group in the changes from baseline to 2 weeks(p<0.05), but there was no significant difference between the groups in the changes from baseline to 4 weeks, from 2 weeks to 4 weeks(p<0.05). 5. A questionnaire was consisted of 5 kinds as to bleeding, pus discharge, pain, burning sensation, patient's satisfaction and all of the questions showed a significant difference compared with the control group in the changes from 2 weeks to 4 weeks(p<0.05). 6. During the 4-week experimental period, important side-effects were not finded out, but each groups had one patient appealed nausea or discomfort respectively. These results indicate that application of periodontitis medical gel was useful as an additional aid of mechanical treatment.

Purpose: The aim of this study was to evaluate the patient’s and dentist’s perspective and knowledge on rapid human immunodeficiency virus screening test in dental setting. Material and Methods: In March 2009, 100 patients and 100 dentists at College of Dentistry, Yonsei University were provided an attitude assessment survey. Results: Results were analyzed for acceptance of testing and potential barriers. 94% of patients agreed to take a rapid HIV screening test and 77% of dentists were willing to provide the test to their patients. Also the current knowledge state of patients and dentists on HIV infection was not accurate as expected. Conclusion: Overall, dental clinic patients widely accepted the offer of rapid oral HIV screening. Rapid HIV screening test in the dental setting can be an important option to increase the number of individuals who know their HIV status.

Purpose: Infection with HIV-1 virus has become a critical worldwide public health problem. The oral complications of HIV infection with its progression of Impairment of the host response to combat infection present unique challenges to the periodontists. Material and Methods : Medline research was carried out to find relationship of the progression of HIV infection to the occurrence of oral lesions including the HIV-related periodontal diseases. Results; The linear gingival erythema, necrotizing ulcerative periodontitis, necrotizing ulcerative gingivitis and oral candidiasis are common lesions in HIV-infected individuals. The linear gingival erythema and necrotizing ulcerative periodontitis lesions in HIV-infected subjects were found to have a similar microbiological profile. There are several general considerations in the periodontal management of the HIV-infected patient with or without periodontal disease. The altered immunity and host response in patients with HIV infection may also affect the incidence and severity of other common forms of periodontal disease not associated with HIV infection. Conclusion: Periodontal diseases in HIV-infected individuals present unique challenges in diagnosis, monitoring, treatment and maintenance. Therefore exact HIV staging, geographic location, antiviral and antimicrobial therapies and oral habits should be taken into consideration when treating HIV-infected patients.
성견치주질환 이환 발치와내 이식 치근과 발치와 치조골 재생에 대한 연구;I. 치근활택술의 영향
김종관,채중규,조규성,김진,한수부,최상묵,Kim, Chong-Kwan,Chai, Jung-Kiu,Cho, Kyoo-Sung,Kim, Jin,Han, Soo-Boo,Choi, Sang-Mook 대한치주과학회 1994 Journal of Periodontal & Implant Science Vol.24 No.1
The authors have transplanted periodontally involved roots which had been root planed into healthy and periodontally involved extraction sockets, and studied the root resorption patterns as well as its effect on new bone formation and wound healing. Alveolar bone around mandibular premolars of 6 adult dogs has been surgically removed, followed by ligation of orthodontic elastic wires for 8 weeks inducing chronic periodontal disease. After removing the crown portions, roots were extracted, and notches were made on the root surfaces discriminating healthy and periodontally involved areas using burs. Controls and experimental groups were divided as follows. Control I : Transplantation of periodontally involved root into healthy extraction sockets. Control II : Transplantation of periodontally involved root into diseased extraction sockets. Experimental group I : Transplantation of root planed roots into healthy extraction sockets. Experimental group II : Transplantation of root planed roots into diseased extraction sockets. Extraction sockets were sutured after transplantations, completely submerging the roots. Healing progress was histologically observed at 2nd, 8th, 12th, and 20th weeks, and the results were as follows ; 1. No inflammation or infection within the extraction sockets had been observed in all groups throughout the experimental period. 2. Reversal lines were observed at week 2 in all groups, clearly discriminating socket walls and new bone, and numerous blood vessels were observed in the new bone trabeculae. 3. Experimental groups showed markedly less root resorption compared to the controls at week 2, but as time progressed, severe resorptions were present in all groups. 4. Localized areas of new bone ankylosis were observed, and the rest of the areas showed collagen fiber insertion with new bone formation at its periphery. 5. No clear differences were found in healing and alveolar bone regeneration between healthy and diseased extraction sockets. 6. The amount of root resorption and ankylosis had increased up to week 8 and 12, showing ankylosis of new bone and the roots. However, no further increase in ankylosis was observed at week 20. 7. Most of the cementum on healthy roots was directly ankylosed to new bone at week, 2, and were gradually resorbed and replaced by new bone thereafter. These results appear to indicate that root planing may inhibit early root resorption of transplanted roots, but gradual replacement by alveolar bone and collagen fibers eventually occur. Condition of the roots or presence of disease in extraction sockets do not appear to make marked differences in alveolar bone regeneration process.
