Among these, 15 received Dipyrone (group I) and the other received acetaminophen (group II) in the postoperative. All patients were treated pre-operatively with dexamethasone 4 mg and amoxycillin 1 g, one hour before surgery. Pain intensity was evaluated by a visual analogue scale by forty eight hours postoperative period and in intervals of six hours. The exclusion criteria were: presence of systemic disorders, drugs hypersensitivity, pregnant, lactic and local contraindications. The scores obtained were submitted to the Mann-Whitney test (p < 0,05) for comparison of the pain intensity in the 6 hours intervals, in the initial 24 hours, in the last 24 hours and in the total period of 48 hours. RESULT: There was no statistical difference among the analgesics in the 6 hours intervals, however, in the last 24 hours and in the total period of 48 hours, the group I presented smaller medium values, significant statistically, when compared to group II.
