The aim of the present study was to structure and validate an index of the level of surgical difficulty in the removal of impacted lower third molars. The design of this study followed two steps. In the first, a cross-sectional analysis of patients submitted to at least one surgical removal of a lower third molar was carried out within a four-year period-seeking the structuring of an indexafter analysis of demographic radiographic clinical variables. In a second step, a prospective cohort study was performed, involving patients submitted to the same surgical procedures‚??cross-referencing the level of difficulty determined with the use of the index in the preoperative phase, and the level of difficulty determined in the trans-operative phase‚??in order to verify the validation of the use of the created index. From a total of 1,033 surgical procedures, 753 were analyzed in the first stage, identifying the most important variables and demonstrating the level of significance of each. The applicability of the index was performed in 280 surgical procedures. In cases with low difficulty, 93.1% were evaluated as low difficulty, according to the index. And in cases with high difficulty, difficulty was registered at a rate of 87.9%, according to the classification of the index. It was possible to structure a measurement index of the level of surgical difficulty in the removal of impacted lower third molars, which proved to be a reliable instrument to predict difficulty, demonstrating high sensitivity, specificity and accuracy.
