Abstract

In this study, aqueous extract of propolis, which is a natural bee product, tested for treatment of recurrent aphthus stomatitis (RAS). A total of 40 patients with RAS divided into 4 groups. Each patient received one of following preprepared mouthwash: Group A received aqueous propolis extract at 1% concentration. Group B received aqueous propolis extract at 0.5% concentration. Group C received dexamethosone at 0.1% concentration. Group D received distilled water. (Control group). The study was double blind and the patient instructed to use the mouthwashes for 5 min 3 times daily. The results of study showed significant difference between groups in pain score assessed at day 2 of study. High percentage of no pain recorded in group A comparing to other groups. However at 5 days of drug therapy no significant difference noticed among the groups regarding pain score. For assessment of healing after 5 days, although no significant difference noticed among the groups, group A reported to show high percentage of complete healing comparing to other groups. Also groups A, B and C showed 50% healing of ulcer comparing to only 20% in patient on group D. In conclusion, aqueous propolis extract at 1% concentration showed good percentage of early reduction of pain score and rapid healing of ulcer with minimal side effect and further studies on other extract and concentration may be recommended.

Abstract

In this study, alkalinizetion of commercial local anesthetic solution was attempted in order to determine its effect on onset and pain experienced during injection as well as its effect on depth of anesthesia achieved for maxillary tooth extraction. Total 200 patients participated and randomly distributed into two groups, 100 patients for each. The first group received maxillary infiltration anesthesia for extraction of maxillary tooth with commercial local anesthetic solution at pH 3.5, and the second group received the same injection with alkalinized solution to pH 7.2 using sodium bicarbonate 8.4%. The result of this study showed a significant rapid onset in pH adjusted group comparing to control group. Significant difference noticed between both groups regarding pain noticed during injection with less pain experienced in study group. No significant difference in the depth of anesthesia achieved. When data assessed for patients with periapical lesion only, a significant difference noticed between pH adjusted group comparing to control group and less pain recorded during extraction with enhanced depth of anesthesia achieved in study group. In conclusion, pH adjusted anesthesia, although not recommended routinely, co-uld be used to reduce injection pain when severe pain on injection expected. Also, it could be used for patient with periapical lesion to enhance depth of anesthesia.

Abstract

In this study, the change in plasma glucose half an hour after injection of different vasoconstrictors contained in local anaestheticsolution where measured both in normal and diabetic volunteers. Single cartridge contain (1.8) ml of plain (2%) Xylocain or that with (1:80000) concentration of a adrenaline or (3%) prilocain with (0.03) IU of felypressin injected at labial to left maxillary lateral incisor region.The result showed that half an hour after injection of a adrenaline containing solution, a very highly significant increase in plasma glucose noticed in both study groups from pre-injection base line value (p<0.001). Increase in plasma glucose in diabetic group were significantly greater than that in normal control group (p<0.05). Within diabetic volunteers, this increase were significantly greater in insulin dependent diabetic group than that in non insulin dependent volunteers. After injection of plain solution or that containing felypressin, reduction in plasma glucose noticed. In conclusion, adrenaline contained within local anaesthetic solution produce hyperglycemic effect even in dose of single dental cartridge. This response enhanced in diabetic patient in general with greater enhancement noticed in insulin dependent patient.

Abstract

Aims: To assess the effect of alkalization of local anesthetic solution for the purpose of enhancing itsefficiency in periapical surgery. Materials and Methods: A total sample of 80 patients, all needingperiapical surgery on one or more of their upper anterior tooth (teeth) was subjected to this trial. For thepurpose of comparison, the sample was randomly divided into two groups based on the local anestheticsolution that they were to receive before surgery. The first group(control) included those patients whoreceived the commercially available local anesthetic solution with a standard pH of 3.5.The secondgroup (trial group) included those patients who received a pH adjusted local anesthetic solution at 7.2(using sodium bicarbonate).Prior to, and at the completion of intended surgery, the following datawere recorded: Pain during injection, onset of achievement of surgical anesthesia, pain duringoperation and the duration of operation itself. Results: A significant difference in regard to onset ofachievement of surgical anesthesia between both groups was noticed with a faster onset in group two where the patients received a pH adjusted local anesthetic solution when compared to control group where the patients received the commercially available local anesthetic solution. Also, less pain on deposition of solution was noticed in the second group as well as less pain score levels were recorded during operation in regard to the same group. Conclusion: The pH adjusted local anesthetic solutionsmay provide certain advantages when compared to the commercially available local anesthetic solutions regarding enhancement of anesthetic efficiency, reduced pain on injection as well as during surgery.

Abstract

This study compared the clinical efficacy of different mouthwashes [0.2% chlorhexidine gluconate (CHX), 0.5%, 1% water extract of propolis, 0.5%, 1% ethanolic extract of propolis] with distilled water in their ability to inhibit plaque accumulation. In this double blind study, 10 (8 males and 2 females) dental students volunteers aged from 20-24 years, 1120 tooth surfaces from 280 teeth were examined. Each volunteer received a final professional tooth cleansing and was instructed to stop all mechanical tooth cleaning effort for next 5 days, where the mouthwashes used 3 times daily. Plaque system index (Silness and Löe, 1964) was obtained from teeth surfaces (buccal, lingual, mesial and distal) before and after the uses of mouthwashes. The results of this study showed significant difference (p < 0.05) between 0.2% CHX, 0.5% and 1% water extract of propolis, 0.5% ethanolic extract of propolis and distilled water, but non significant difference (p > 0.05) between CHX and 1% ethanolic extract of propolis in their ability to inhibit plaque accumulation. It can be concluded that the alcoholic extract of propolis may be used as adjunct to mechanical plaque control during the maintenance phase of therapy to ensure sustained low plaque level and this may meet patient approval because it is a natural substance and devoid of industrial chemical component.
