Eficácia do laser de baixa potência (LPL) na redução da morbidade após exodontia de terceiros molares: teste clínico triplo-cego de boca dividida

Abstract

The extraction of third molars usually brings significant morbidities to the patient and, therefore, discussions about the effectiveness of low-level laser in reducing morbidities have been open. The objective of this study is to evaluate the effectiveness of the use of laser in the reduction of morbidities after extraction of lower third molars. The third molars (38 and 48) were randomly allocated to the test group that received the laser application protocol and the placebo group that received the sham application protocol, making a total sample of 44 surgeries. Patients in the test group used an average of 1/2 the amount of analgesics than those in the placebo group, however, only on days four and five was there a statistically significant difference. Regarding trismus, the test group showed better indicators both at 48 hours and at 7 days after surgery compared to the placebo group, but without a statistically significant difference. Regarding edema, the group that received placebo showed better indicators when compared to the test group, but without a statistically significant difference. The use of laser showed better indicators of pain and trismus after extraction. However, only in relation to pain it presented statistically significant results.
