Avaliação do uso da dexametasona pré-operatória na redução da dor, edema e trismo na remoção de terceiros molares inferiores: estudo clínico, randomizado, prospectivo.

Abstract

Evaluation of the use of preoperative dexamethasone to reduce pain, swelling and trismus in the removal of lower third molars: a prospective, randomized, clinical study. The aim of the present study was to evaluate the use of preoperative dexamethasone in the reduction of pain, trismus and edema, after third molar extraction. A total of 40 patients were randomly selected, divided into four groups: A osteotomy only, B osteotomy 8 mg dexamethasone 1 hour before the procedure, C osteotomy / odontosection and D osteotomy / odontosection group + 8 mg dexamethasone 1 hour before the procedure. The variables evaluated were, measurement of edema, trismus and evaluation of painful symptomatology, being analyzed in two periods 24 hours and 7 days after the surgical procedure. Data were tabulated in the bioestat 5.0 program and used the Shapirowilk tests, the student t test and the MannWhitney test. When comparing the data from group A and B, it was possible to observe statistical difference in the reduction of edema in the first 24 hours in the group that used dexamethasone, and it was not possible to verify differences in the limitation of mouth opening and pain. And when comparing the results of groups C and D, it was not possible to verify statistical difference in any of the variables. Concluding that the use of dexamethasone was efficient in reducing edema, when we use only the osteotomy technique, no statistical difference was observed between the other variants and in the groups where the technique was osteotomy / odontosection.
