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.

Aims: To assess the effect of alkalization of local anesthetic solution for the purpose of enhancing its efficiency in periapical surgery. Materials and Methods: A total sample of 80 patients, all needing periapical surgery on one or more of their upper anterior tooth (teeth) was subjected to this trial. For the purpose of comparison, the sample was randomly divided into two groups based on the local anesthetic solution that they were to receive before surgery. The first group(control) included those patients who received the commercially available local anesthetic solution with a standard pH of 3.5.The second group (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 data were recorded: Pain during injection, onset of achievement of surgical anesthesia, pain during operation and the duration of operation itself. Results: A significant difference in regard to onset of achievement 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 solutions may 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.

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.

Aim:To asses the effects of topical application of aqueous extract of either Propolis or Miswak on the post-operative outcomes in relation to the duration of operation after surgical removal of lower third molar was performed. Material and Methods: A total of 97 patients participated and distributed randomly into 3 groups according to the medicament applied into the extraction socket: Group I, in which 5% aqueous solution of propolis extract used; group II, in which 10% aqueous solution of Miswak extract used; and group III, in which distilled water used (control group). Results: A significant improvement in post-operative outcome at 3 rd day in both group I and II comparing to group III was observed. No significant difference noticed at 1 st day and 6 th day. Assessment of dry socket showed no significant difference in between the three study groups. However, when assessment performed in relation with operation time, a significant difference noticed in between the three study groups with high incidence of dry socket reported in operation take longer than 30 minutes in the three study groups. Conclusion: Aqueous extract of Miswak and Propolis as a topical medicament following lower third molar extraction had a slight reducing effect on the severity of post-operative complications.Al-Sultan FA, Mustafa LA, Al-Niaimi AI.
