Pain Control Effects of Myprodol(R) after Periodontal Surgery and Dental Implant Surgery / 대한치주과학회지

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 operationgroup, 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.

A Clinical Study of the Effect of Periodontitis-Medical Gel on Human Gingivitis and Periodontitis / 대한치주과학회지

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.

The effect of newly designed toothbrush on plaque control, treatment of gingivitis and periodontitis / 대한치주과학회지

The present study investigate the effect of newly designed toothbrush(Chess tip : experimental group , conventional toothbrush(control group) on plaque control, gingivitis, and peridontitis. 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.
