The signs and symptoms after surgical removal of the impacted mandibular third molar tooth can include pain, trismus and swelling; there are many modalities to treat these signs and symptoms like pain killer and non steroidal anti-inflammatory drugs. Low power laser therapy can be one of these modalitiesThe aim of the study is to investigate the effects of low power laser therapy, diclofenac sodium or in combination in reduction of post operative signs and symptoms.Material and methods: A total of 40 patients requiring surgical removal of mandibular third molars were divided in 4 groups of 10 patients in each group: the first group treated with low power laser therapy, group 2 was treated with diclofenac sodium, group 3 was treated with combination of low power laser and diclofenac sodium and group 4 was treated with placebo.Results: the postoperative pain records for group 1, group 2 and group 3 were pain records less than that for group 4. The mean of postoperative mouth opening measurements records for group1, group2 and group 3 were more than the group 4. Also the mean of postoperative swelling records for group1, group2 and group 3 were less than the group 4These results may agree with most researchers in proving that Low power laser therapy can be beneficial in the reduction of post-operative signs and symptoms; however the methods of application and the doses of laser power need further investigations.In conclusion low power laser therapy alone or with combination with Diclofenac sodium medication can be good procedure for the reduction of postoperative signs and symptoms after surgical operation of removal of mandibular third molar. Diclofenac sodium medication alone was superior to Low power laser therapy alone .

During this study, a comparison of antimicrobial effects of garlic and onion extract on some gram negative bacteria were assayed in vitro. Primarily, each of these microorganisms including Escherichia coli, Salmonella typhi, Klebsiella pneumonia and Pseudomonas aeruginosa were isolated and diagnosed from patients suffering from different infection cases. This step was followed by preparation of aqueous extracts from onion and garlic. Furthermore, the activity of the two extracts on those microorganisms was tested by using different garlic extract concentrations, and application cup–plate diffusion and total count methods. It was noticed that increasing garlic aqueous extract concentration, would lead to a notable increase in inhibition zone diameter, compared with control. However the inhibition zone diameter was about 28 mm for Salmonella typhi, at concentration of 500mg/0.5ml of garlic extract was used; while the diameter was about 26–30–16 mm for the same concentration for each of K. pneumonia, Escherichia coli and P. aeruginosa respectively. Moreover a comparison was done between these results and that obtained when using onion aqueous extract. It was observed that the activity of garlic was more than onion which gave inhibitory zone diameter of about 25–16–17 mm to each of S. typhi, K. pneumonia and E. coli respectively , at concentration of 500mg/0.5ml; but the P. aeruginosa was unaffected. Other observation was show that there is adecrease in number of isolated microbial cells by increasing both extract concentrations, hence when treating the bacteria with garlic extract of 500mg/0.5ml concentration, the number of cells forming colonies were 62 10 , 71 10 , 12 10 and 13 10 cell/ml for each of S. typhi, K. pneumonia, E. coli and P. aeruginosa respectively. In the other hand, the number of colony forming unit for the same bacteria were 16 10 , 31 10 , 1 10 and 8 10 cell/ml when using onion extract of 500mg/0.5ml concentration.
