Periodontal disease, trauma, deformity of tooth can jeopardize the esthetics of oral and maxillo-facial region. Moreover, increasing the demand and concern about the esthetics, clinicians should place high value on esthetics during periodontal treatment. Analysis of various anatomical considerations; lip line, shape and location of marginal gingiva, and biologic width; and diagnosis should be performed prior to periodontal plastic surgery.

Although various analgesics have been administrated for postoperative pain control, postoperative pain has not been adequately controlled . The purpose of this study was to evaluate the effects and patient's satisfaction of $Myprodol^{(R)}$(combination analgesics with codeine, ibuprofen, paracetamol) compared to Acetamionphen and placebo drug after periodontal surgery and dental implant surgery. We studied 98 cases of outpatients which were composed of 67 cases of flap operation(which separated to 3 groups: Placebo group(n=25), $Myprodol^{(R)}$ group(n=22), Acetaminophen group(n=20)) and 21 cases of dental implant surgery(which separated to 3 groups : Placebo group(n=10), $Myprodol^{(R)}$ group(n=12), Acetaminophen group(n=9)). We evaluated the postoperative pain(Pain 1), Pain after first drug administraion(Pain 2), the degrees of pain reduction(pain 3), patient's satisfaction for drug, and side-effects. We obtained following results; 1. In Pain 1, making a comparison among groups, there was no significant difference in both cases of flap operation-group and dental implant surgery-group 2. In Pain 2, establishing a comparison among groups, there was no significant difference in flap operation-group, but significant difference was seen between placebo group and $Myprodol^{(R)}$ group in cases of dental implant surgery group(P<0.05). 3. In Pain 3, making a comparison among groups, $Myprodol^{(R)}$ group showed significant differences compared to placebo group and Acetaminophen group in both cases of flap operation group and dental implant surgery group(P<0.05). 4. In patient's satisfactory score, making a comparison among groups, there were significant differences between placebo group and $Myprodol^{(R)}$ group in cases of flap operation group and between $Myprodol^{(R)}$ group and Acetaminophen group in cases of dental implant surgery group(P<0.05). 5. Making a comparison in side-dffect, no significant differrence was seen. Our conclusion is that $Myprodol^{(R)}$ is a effective oral analgesics to the patients who underwent periodontal surgery or implant surgery for it's synergism among three dugs.

Purpose : Preservation of the periodontal health of the treated patient requires supportive periodontal therapy for the elimination of periodontal disease. After Phase I therapy is completed, patients are placed on a schedule of periodic recall visits for maintenance care to prevent recurrence of the disease. The amount of tooth loss would be the most relevant criterion in an evaluation of the effect of periodontal treatment, but this would require studies with extremely long follow-up periods. Thus the most commonly used outcome criteria in clinical research have been clinical attachment level change, reduction of pocket depth and bleeding frequency. The purpose of this case study is to identify the effect of supportive periodontal therapy after periodontal flap surgery. Materials & Methods : Following routine hygienic phase of treatment, patients with chronic periodontitis received surgical periodontal treatment. Bleeding on probing, pocket depth and clinical attachment level were measured at baseline, pre-operation and 1 year follow up. All procedures were performed by one operator. Results : One year a total of 28 patients (58sites) to recheck remained, when conducted maintenance program after periodontal flap surgery was observed reduction of bleeding frequency, pocket depth and improvement of clinical attachment level. Conclusion : The results from this study indicate that supportive periodontal therapy after periodontal flap surgery is effective for reduction of bleeding frequency, pocket depth and gain of clinical attachment level.

The purpose of this study was to evaluate the effects of administration of Zea Mays L. on the healing process after periodontal surgery as adjuntives. Authors used 3 kinds of different clinical criteria, depth of periodontal pocket by using the Goldman Fox periodontal probe, degree, of tooth mobility by Periotest, and amount of occlusal force with electronic device. In this comparative clinical study, 30 patients who were divided into two group, 15 ZML administrated group and 15 placebo adminstrated group, were participated. All the examined teeth were isolated with gauze and air spray, and measured each clinical critera on the day of before surgery, 1, 2, 4, 8 weeks after surgery. The results were as follows. 1. The changes of the periodontal pocket depth, on the both of Zea Mays L. administrated group and placebo adminstrated group, revealed the decreasing tendency, and it was shown the time dependent tendency. But there was no statistically significant differences between the two group. 2. In the case of tooth mobility, both group showed the highest severe mobility on the 1 week after surgery. It was observed that experimental group had more effects on decreasing the mobility. But there was no statistically significant differences between the two group. 3. In the case of experimental group, the recovery trend of occlusal forces after periodontal surgery on the molar teeth revealed higher than the control group. But there was no statistically significant differences between the two group. In conclusion, Zea Mays L. may play a favorable role in the healing process after periodontal surgery. It was suggested that further study to evaluate the effects of selective administration on the patient who have systemic diseases should be needed.

Purpose : The purpose of this study was to identify and assess factors that may contribute to pain of patients undergoing implant surgery. Materials and Methods: A total of 24 patients who underwent implant surgery were included in the study. Each patient's anxiety was measured using Corah's dental anxiety score(DAS) and modified Spielberger's state-trait anxiety inventory(STAI) immediately after the operation. Also, level of pain was measured using visual analog scale(VAS) during the operation and 48 hours after the surgery. The effect of various factors, such as demographic variables, previous dental experiences and operation time were also analyzed. Results: Postoperative pain levels were relatively low than expected. However, DAS and STAI were high among patients, and it showed that patients had anxieties about implant surgery according to DAS and STAI values. The previous dental experience did not affect the pain level, but the duration of surgery and the presence of accompanied advanced surgery did. Conclusion: To reduce patient's pain, proper management of anxiety will be required and careful attention is needed when performing local infiltration.

The ultimate goal of periodontal therapy is the regeneration of periodontal tissue which has been lost due to destructive periodontal disease. Various periodontal procedures have been used throughout the years in an attempt to reestablish attachment of periodontal tissues to root surfaces affected by periodontitis. Flap debridement surgery has been demonstrated to be a successful procedure in gaining the probing attachment level and reducing probing depth. A tendency towards impaired wound healing following periodontal procedures in smokers has been clinically documented. But, previous clinical studies on healing response in smokers are based on a retrospective design. The purpose of this study was to evaluate the treatment outcome following flap debridement surgery in smokers compared to nonsmokers. 25 patients with moderate to advanced periodontitis were included for study. Among these patients, 13 patients were smokers, and 12 patients were nonsmokers. Mucoperiosteal flap was raised with the sulcular incision. No antibiotic treatment was administered postsurgery. The patients was recalled at monthly intervals during a period of 6 months following the surgery. The patients were received supragingival scaling and oral hygiene reinforcement. All the recordings, including modified O' Leary plaque control record, bleeding on probing, probing pocket depth, probing attachment level,were recorded, presurgery and 6 months postsurgery. The changes of all the recordings at 6 months after flap debridement surgery revealed the following results: 1. PI on all the dentitions and surgical sites showed no statistical significance between smokers and nonsmokers at presurgery. But, smokers demonstrated a significantly lower % of PI than nonsmokers at 6 months postsurgery. 2. Smokers demonstrated a greater % of BOP sites than nonsmokers on the surgical sites and all the dentitions, presurgery and 6 months postsurgery. But, there was no statistical significance between two groups. 3. Smokers exhibited significantly less reduction of probing depth in the 3 mm or less probing pocket depth(PPD) group, 6mm or more PPD group and total PPD group when compared to nonsmokers at 6 months postsurgery. 4. Smokers exhibited significantly less gain of probing attachment level(PAL) in the 3mm or less PPD group, 6 mm or more PPD group and total PPD group when compared to nonsmokers at 6 months postsurgery.

The aim of this study was to recommend the optimal age for prevention of periodontal disease and to investigate the trend of treatment modality according to different period. From the chart recordings of the patients who had been treated periodontally from Jan. 1981 to Dec. 1995 in the dept .of periodontics, Chosun University Dental Hospital, those of the periodontally treated patients on more than 4 sixtants were selected for the present study. The distribution of the patients was counted according to the age group and the gender. And they were divided into 3 groups(group 1: 1987-1958, group 2: 1985-1990, group 3: 1991-1995) by 5 year interval according to the treated year. The periodontal treatment modalities were classified into non-surgical therapy, pocket elimination surgery, regenerative periodontal surgery, mucoginigival surgery, clinical crown lengthening, and others. The results were as follows; 1.In the distribution of the periodontally treated patients according to the age group, 40's age group was the highest, and 30's, 40's, and 50's age groups occupied more than two thirds(73%). 2.The sexual distribution of the periodontally treated patients showed that males(53.4%) were a little more than females(46.6%). Within 20's group female was higher, but within 40's male was higher. 3.Regardless of the age group and the gender, pocket elimination surgery was the most frequent treatment modality. 4.In group 1 and 2(1987-1990) the main treatment modality was pocket elimination surgery and non-surgical therapy, but in group 3(1991-1995) it was regenerative periodontal surgery and pocket elimination surgery. The above results suggest that the prevention of periodontal disease should be initiated from early twenties, and the most frequent treatment modality may be closely related with development of new material and method.

Ingredient analysis and the medical action of various teas are accomplished on multi angle. However, the research regarding the prevention and a treatment of oral cavity disease, which use the green tea, is still insufficient relatively. In this experiment, the virtue of green tea bag on periodontal disease was studied. This experiment was used in 11 beagles. As a test group, 6 beagles were rinsed their tooth with green tea bag. The remaining 5 beagles were rinsed with filter paper which was soaked with normal saline. The test found no statistical significance in gingival index, plaque index, calculus index and dental pocket depth. But the number of bacteria colonies decreased significantly in test groups. The periodontal disease is related to the number of bacterial colonies. Therefore, this results show that the green tea bag is effective for periodontal disease.

In the treatment of chronic adult periodontitis, scaling and root planing have been generally performed prior to periodontal flap surgery. The purpose of this study was to evaluate the clinical significance of nonsurgical periodontal therapy prior to periodontal flap surgery in patients with chronic adult periodontitis. Fifty six molars showing bilateral bony defects and 4-6mm periodontal pocket in twelve patients with chronic adult periodontitis were selected. By randomized split-mouth design, in one side, flap operation was performed 4 weeks after scaling and root planing, in the other group, flap operation was only performed without scaling and root planing. Probing pocket depth, gingival recession, clinical attachment level, gingival index, plaque index, and tooth mobility were measured at baseline, before flap operation and post-operation

The periodontal flap surgery is the most widely utilized surgical procedure to reduce the pocket depth and to access the subgingival root surfaces for scaling and root planing. The diagnosis of the periodontal lesion and the objective of the surgery will dictate the type of flap procedure which will be utilized to obtain the best result. The incisions, type of flap and the selection of suturing design must be planned and executed to fit the problem. Periodontal flaps are designed to preserve gingival integrity and to gain access to root surfaces for residual calculus removal and to thoroughly remove granulation tissue so bone defects can be visualized and treated. Gentle and efficient procedures result in optimum healing and minimal postoperative pain. When flaps need to be repositioned apically or less often, coronally, then the flaps must sit passively at the appropriate level before suturing. To ensure this, buccal and lingual flaps need to be elevated beyond the mucogingival junction so the elasticity of the mucosa allows for flap mobility. Sometimes it may be necessary to extend the flap elevation apically with a split incision approach to minimize the effect of the less elastic periosteum. Vertical incisions can aid in flap positioning by allow ing the clinician to suture the flap at a different level to the adjacent untreated gingiva. In osseous periodontal surgery, flaps are apically positioned to minimize postoperative pocket depth. In regenerative periodontal surgery including implant surgery, soft tissue cove rage of bony defects, graft materials, membranes, and bio logic agents is important so sulcular incisions and light suturing techniques are crucial.
