Introduction: The lower third molar is the tooth that has the highest impaction, when we extract these pieces, we often have greater surgical difficulty. Therefore, it is of great importance to determine the degree of pre-surgical difficulty in order to determine the inflammatory response after performing the surgical procedure. The clinical evaluation of the surgical site after 48 hours, can tell us objectively how the inflammatory response can be. General objective: To determine the association between the degree of pre-surgical operative difficulty according to the Pederson classification with the clinical evaluation of the surgical site post extraction of lower third molars. Materials and methods: This study was: retrospective, observational and analytical. The sample was made up of 59 records of lower third molars extractions, we evaluated the following variables: Increase in soft tissue volume, inflammation of the edges of the wound, spontaneous bleeding, presence of hematomas, spontaneous pain, pain on palpation and mouth opening; all of them in a 48-hour post-operative period. Analysis plan: A descriptive analysis was carried out by obtaining absolute and relative frequencies of the qualitative variables. A bivariate analysis was also carried out using the chi-square test to find associations between the variables, because all of them were categorical. The study had a confidence level of 95% and p<0.05. The SPSS 24.0 statistical program was used. Results: when analyzing each parameter of the Pederson scale with the corresponding clinical sign, it turned out that the clinical signs with the highest prevalence were: increase in volume, with a total of 23 records (38.98%), inflammation of the edges of the wound with a total of 33 records (55.93%), pain on palpation with a total of 41 records (69.49%) and in the clinical sign of mouth opening, it was decreased in 37 of the 58 records (63.79%). On the other hand, the clinical signs with the lowest prevalence were the presence of spontaneous pain with 8 records (13.55%), spontaneous bleeding and hematoma both with 9 records (15.25%). Conclusion: Pederson's pre-surgical radiographic index is an insufficient predictor of possible post-surgical complications of lower third molar extractions.
