The purpose of this study is to compare the analgesic effect of lysine clonixinate, paracetamol and dipyrone after lower third molar extraction.


The sample consisted of 90 individuals with clinical indication for inferior third molar extraction. The mean age of the sample was 22.3 years (DP +/-2.5). The individuals received the medication in unidentified bottles along with the intake instructions. The postoperative pain parameters were measured according to the Visual Analogical Scale (VAS) and the data was evaluated using the Kruskal-Wallis Test and Friedman Test, with the latter used to test different time intervals for each one of the drugs.


The final sample consisted of 64 individuals, including 23 males (45.9%) and 41 females (64.1%) The mean age of the entire sample was 22.3 years (+/-2.5). The average length of the procedures was 33.9 minutes (+/-9.8). The distribution of mean values for this variable showed little variance for the different drugs (p=0.07).


Lysine Clonixinate did not show any substantial impact on the postoperative pain control when compared to other drugs.
