목적: 치주포대는 감염 위험을 줄이고 치유를 증대 시킨다는 연구들이 있다. 본 연구는 치주 수술 후 부착형 창상 피복재의 사용이 치유 및 수술 만족도에 미치는 영향을 평가하고자 하였다. 연구 재료 및 방법: 치주 수술이 필요한 환자 28명을 대상으로 상악 또는 하악의 양측 사분면에 치주 수술을 시행하였다. Visual Analogue Scale (VAS)를 이용해 술 후 동통, 출혈, 식이 불편감, 지각 과민을 평가하고 추가적으로 작열감과 수술 만족도에 관해 평가하였다. 결과: 수술 후 동통, 출혈, 식이 불편감에 관한 VAS 평균 값은 창상 피복재 유무에 따라 각각; 동통: 2.82, 3.96 (P = 0.002), 출혈: 1.61, 2.54 (P = 0.008), 식이 불편감: 2.82, 4.18 (P < 0.001)로 창상 피복재를 적용한 그룹에서 불편감이 적었으며, 통계적으로 유의하였다. 작열감, 지각 과민과 창상 피복재 적용 유무 사이에 유의한 차이는 없었다. 수술 만족도는 75%에서 창상 피복재를 사용한 경우 높았다. 결론: 본 연구의 결과에 따르면, 창상 피복재의 사용유무와 작열감, 지각 과민과의 통계적 유의성은 없었으나 창상 피복재를 사용한 경우 술 후 동통, 출혈, 식이 불편감이 적었다.

A study was conducted to compare the effects of chlorhexidine mouthrinse and chlorhexidine acetate powder with periodontal pack during 4 weeks following periodontal surgery. Twelve patients were treated with Modified Widman flap procedures and devided into three groups of four patients each; control group, chlorhexidine mouthrinse group, chlorhexidine acetate powder group. Each group wasn't significant difference in clinical and microbiologic parameters at preoperation. Examination regarding plaque index, gingival index, pocket depth, change of gingival color postsurgically, pain index were performed by each methods and observed bacteria in gingiva by phase contrast microscope. Evaluations were made at 7, 14 and 28 days postsurgically. The results were as follows: l. In comparison of results revealed no significant differences in Plaque Index, Gingival Index, pocket depth and change of gingival color postsurgically. 2. The pocket depth of three experimental groups were significant reduced at 4 weeks. 3. Chlorhexidine mouthrinse group and chlorhexidine acetate powder group with periodontal pack were significant differences in pain index at 3, 4 days postsurgically. 4. Cocci and Non-motile rods were increased at 1, 2 weeks. But, motile rod and spirochete were increased at 4 weeks.

The purpose of this study was to compare the effects of Chlorhexidine, Listerine and hypertonic saline mouthrinse without periodontal pack during 2 weeks following periodontal surgery. Twelve patients were treated with modified Widman flap procedures. Each fourth patients assigned to chlorhexidine mouthrinse group, Listerine mouthrinse group and control group. Each group wasn't significant difference in clinical and microbiologic parameters at preoperation. Examination regarding plaque index, gingival index, pocket depth, change of gingival color postsurgically, pain index and contrast phase microscope were performed. Evaluations were made at the first, the second and the fourth weeks postsurgically. The results were as follows: 1. Chlorhexidine mouthrinse group and Listerine mouthrinse group were significantly different in plaque index at the first, the second and the fourth weeks 2. The pocket depth of three groups were significantly reduced at the fourth weeks. 3. Chlorhexidine mouthrinse group and Listerine mouthrinse group were significantly different in change of gingival color at the first week. 4. Cocci and non-motile rods were increased at the first and the second weeks. But, motile rods and spirochete were increased at the fourth weeks.

Since they were introduced by Ward in 1923, periodontal dressing have been routinely used following the periodontal surgery to avoid pain, infection, desensitizing teeth, inhibiting food impaction of the surgical areas, and immobilizing injured areas. Recently, however, the value of periodontal dressings and their effects on periodontal wound healing have been questioned, several authors have been reported that the use of dressing has little influence on healing following periodontal surgical procedures. In addition, there is evidence that when good flap adaptation is achieved, the use of a periodontal dressing does not add to patient comfort nor promote healing. The purpose of this study was to evaluate patient postoperative pain experience and discomfort with and without the use of periodontal dressing following periodontal surgery. Twenty-eight patients, 11 male and 17 female. were selected for this study; The age range was 31 to 56, with an average of 40.2years. Patient selection was based on existence of two bilateral sites presenting similar periodontal involvement, as determined by clinical and radiographic assessment, and requiring comparable bilateral surgical procedures. Using a splitmouth dressing. one site received a periodontal dressing while the other site did not. Pain assessment was made according to a horizontal, rating scale(0-10). After at least a two-week period, the second surgical precedure was performed using the alternate postoperative treatment. At the conclusion of the trial, a self-administered questionnaire on postoperative experience was administered, and were asked of their preference of either, dressed or undressed. The results were as follows: 1. A similar trend for mean pain and discomfort scores as assessed by patients both dressed and salinetreated procedures was evident during 7-day postsurgical period. 2. Statistical analysis of differences between the dressed side and salinetreated side with respect to pain, discomfort and patient's experiences revealed that both treatment sides behaved similarly at any postoperative day(P>0.05). 3. Considering the patient's preference, on the basis of pain and discomfort experienced, 43% preferred the saline-mouthwash and 32% preferred the dressing, 25% showing no preference for either the dressing or the saline-mouthwash. There is evidence to support the use of a periodontal dressing in retention of an apically positioned flap by preventing coronal displacement, or its use to provide additional support to stabilize a free gingival graft. However, there will always be a use for periodontal dressing although routine use of dressings may decrease because of better surgical techniques and the use of antibacterial mouth rinses.

It is well known that the application of dressings after periodontal surgery have benefits to provide the comforts to patient and to promote the healing process with action of bleeding control and temporary stabilization for the operated mobile teeth. But until recently the relationship between periodontal dressings and cells which are composed of periodontium has not been clear. The purpose of this study was to evaluate the cytotoxic effect of soluble extracts from the four different kinds of periodontal dressings, two of them were eugenol type (K.H.pack, Wondrpak) and the others were non-eugenol type (Coe-pak, Periocare), on the human gingival fibroblasts in vitro. Human gingival fibroblasts were primarily cultured from gingiva around third molar during the extraction for preventive purposes. Extracts solution were prepared with culture medium by means of imersing the consistent size of periodontal dressing made from plastic mold. Cell were inoculated into the 24 well plate with $3\;{\times}\;10^4\;cells/well$ of medium at $37\;^{\circ}C$, 100% of humidity, 5% of $CO_2$, incubator for 24 hours. After discard of the supernatant of medium, those cells were cultured with original, 1/2, 1/5, 1/10 diluted soluble extract for 24, 48 and 72 hours, and counted the number of cells using the hemocytometer at each designed time and concentration. Also, the cytotoxic effect of soluble extract was measured by Wataha's MTT assay method. In briefly, cells were inoculated and cultured into 96 well culture plate with $2\;{\times}\;10^4\;cells/well$ for 24 hours. Soluble extracts were applied to cultured cells and incubated for 48 hours at same condition. $50\;{\mu}l$ of MTT solution and DMSO were added into each well for the detection of absorbance with ELISA reader. The measured data were calculated by value of colorimetric assay for survival rate. The results were as follows ; In the case of eugenol type of dressing, original, 1/2 and 1/5 diluted extracts of K.H.pack showed very low survival rate. And original extract of Wondrpak showed strong cytotoxic effect and 1/2 diluted extract showed moderate cytotoxic effect. In the case of Non-eugenol type of dressings, only original extract of Coe-pak revealed strong cytotoxic effect and Periocare had little cytotoxic effect. It is concluded that eugenol type of dressings showed more cytotoxic effect than non-eugenol types. This study suggest that use of non-eugenol dressings after periodontal surgery is recommended.

제1대구치는 저작과 혼합치열기 이후의 수직적 교합관계형성에 핵심적인 역할을 하고 악골의 성장발육에 관여한다. 제1대구치의 매복은 하안면 고경의 감소, 낭의 형성, 치관 주위염, 인접치의 치근 흡수, 부정 교합 등의 문제점을 야기할 수 있다. 치료방법으로는 주기적 관찰, 외과적 노출술, 교정적 견인, 외과적 재위치술, 발치 등이 있으며 이중 외과적 노출술이 가장 기본이 되는 술식이다. 외과적 노출술시에는 맹출로의 개방성을 유지하는 것이 중요하며 개방성을 유지시키기 위한 방법으로는 레진관의 접착, 산화 아연 유지놀 시멘트, 치주포대 등을 노출된 부위에 충전시키는 방법 등이 있다. 본 증례에서는 매복된 하악 제1대구치에서 장애물의 제거와 외과적 노출술을 시행한 결과 자발적인 맹출을 관찰할 수 있었다. 또한 surgical pack과 투명상유지장치를 사용하여 간편하고 효과적으로 맹출로의 개방성을 유지할 수 있었다.
