The surgical removal of third molar teeth can result in bacterial infections disease. Therefore, controversy has arisen about the necessity of prophylactic antibiotic treatment. Purpose: The aim the present study was to evaluate the need for prophylactic oral antibiotic treatment in the removal of asymtomatic third molars. Patients and Methods: Forty five patients were assigned at randon for antibiotic protocol.Three groups were established In the first group, antibiotic treatment with oral Amoxicillin 500mg, 3 times daily was carried out for 7 days postoperatively. The second group received 2g oral Amoxicillin one hour before surgery. In the third group the patients received placebo. We evaluated infection and adverse postperative side effects. All data were tabulated and statistical analyzed by test. Results: In three patients, an infection was developed. All patients belonged to the placebo group, showed significant differences. We could not find any significant difference between the first group and second group. Conclusions: Our results showed that a single dose before surgery could be so effective than the 7 day- treatment after surgery to prevent postoperative infection, and therefore should be recommended.
