  • The purpose of this study was to evaluate photothermal effect of laser, which eliminates and reduces bacteria causing periodontal disease, on treatment of periodontal disease. This study included subjects with moderate periodontitis who visited the Department of Oral Medicine, College of dentistry, Yonsei University. The subjects were divided into experimental group, where Argon laser treatment was used, and control group, where conventional subgingival curettage was used. Gingival fluids from each subject were collected prior and after 1 week of the treatment, and changes in number of bacterial colonies cultured from aerobic as well as anaerobic bacteria responsible for the periodontal disease, and changes in clinical indices related to the periodontal disease, such as plaque index, gingival index, sulcus bleeding index, were analysed. As a result, the number of bacterial colonies of aerobic and anaerobic bacteria reduced after 1 week of the treatment in both groups, especially the bacterial colonies of anaerobic bacteria which showed statistically significant reduction(p<0.1). However, there was no significant difference between the experimental group and the control group. Clinical indices including plaque index, gingival index, sulcus bleeding index were reduced after 1 week of the treatment in both groups. In the experimental group, gingival index(p<0.1) and sulcus bleeding index(p<0.01) showed significant reduction, and, in the control group, sulcus bleeding index(p<0.01) showed significant reduction. However, there were no significant differences in each indices between the two groups. The above results suggest that Argon laser could be used as a substitute of conventional subgingival curettage, or in combination with subgingival curettage which would increase the effect of the treatment. Although the possibility of clinical application of Argon laser was observed in this study, more randomized-controlled research, including acquirement of sufficient samples as well as long-termed follow up, would be necessary before clinically effective application of Argon laser.

  • 최근의 레이저 기술의 발전은 치의화영역에서 많은 가능성을 제시해 주고 있으며, 레이저를 이용한 외과적 치료의 기전과 안전성은 많은 분야에서 입증되어 있다. 근래에는 치주학적 분야에도 레이저를 적용하려는 노력이 계속되어 왔으며, 치석의 제거나 치근면의 세균제거 등에서 효과를 제시한 연구들이 있었다. 본 연구의 목적은 $CO_2$ 레이저를 통상적 치은연하소파술과 병용하였을때의 임상적 효과를 임상 지수의 측정을 통하여 평가하는 것이다. 만성 중둥도-고도의 치주염으로 진단된 12명의 환자가 본 임상연구에 포함되었다. 한 환자에서 각각 2부위의 사분악을 선택하여 임의로 2가지 치료군에 다음과 같이 나누어 포함시켰다: 1) 치은연하 소파술만을 적용한 사분악을 대조군 2) 치은연하 소파술과 0.8W의 에너지 수준을 갖는 $CO_2$ 레이저를 병용하여 적용한 사분악을 Laser 군으로 포함하였다. 치주낭 탐침 깊이, 임상 부착 수준, 치은 퇴축 및 탐침시 출혈풍의 임상지수를 치료전과 술후 각각 1, 3, 6개월 경과시에 측정하여 다음과 같은 결과를 얻었다. 치주낭 탐침 깊이, 임상 부착 수준, 치은 퇴축 및 탐침시 출혈 등의 모든 측정한 임상지수에서 치료전 ${\cdot}$ 후를 비교하였을 때 통계적으로 유의한 개선을 보였다. 그러나 실험군과 대조군간의 비교에서는 치주낭 탐침 깊이, 임상 부착 수준에서는 통계적으로 유의한 차이를 보이지 않았다. 탐침시 출혈은 술후 6개월시에 Laser군에서 대조군에 비하여 통계적으로 유의성있는 차이를 보이며 감소하였다(p<0.05). 결론적으로 $CO_2$ laser를 비외과적 치주 치료에 부가적으로 적용하였을 때 염증 감소에 기여할 가능성이 있을 것으로 사료된다.

  • Enlargement of the gingiva caused by phenitoin, an anticonvulsant used in the treatment of epilepsy, occurs in some of the patients receiving the drug. Its incidence varies from 3 to 62 percent, with the greater frequencies in younger patients. The hyperplasia is usually generalized throughout the mouth, but is more severe tendency in the maxillary and mandibular anterior regions, 18 year old male patient was admitted to our Department of Dentistry with the complaint of generalized painless gingival swelling. After the consult of the N.M. and laboratory study, the gingivectomy and gingivoplasty was performed. The periodontal pack and tin foil was applied on the attached gingiva to protect a surgical site and bleeding control. We obtained a good result of improved esthetics and function.
