Dexametasona versus laserterapia de baixa intensidade: os efeitos na dor, edema e qualidade de vida após cirurgia de bichectomia: um ensaio clínico

Abstract

In current study, we aimed to compare the effects of low-level laser therapy and dexamethasone in the pain, swelling and quality of life in patients submitted to buccal fat pad removal. About the methodology, it was surveyed 20 patients who pseudo-herniation of buccal fat pad or aesthetic complaint. The patients were randomly separated into two groups: low-level laser therapy group (LLLT, 660nm, 100mW, 6s, 2J/cm2) and dexamethasone group (DXM, 4mg each 8 hours for 3 days after the procedure). The pain was evaluated through visual analogic scale (VAS) at day 2 and 4 post surgically, to edema evaluation was measured the distance between six reference points: tragus (Trag), pogonion of soft tissues (Pog), lateral corner of the eye (EC), the angle of the mandible (Gon), wing nose (WN) and mouth commissure (MC) at day 2, 4, 7, 15, 30, 60 and 90. To quality of life was applied the Oral Health Impact Profile (OHIP-14) questionnaire at day 2 and 4 after the surgery. It was observed from the results there were no differences between LLLT and DXM at pain and edema. About the quality of life, the LLLT group were more comfortable to chew than DXM (p< 0,05). It was therefore concluded the utilization of LLLT at the parameters of 100mW of power and 2J/cm2 per point demonstrated similar effects of DXM orally in the control of pain and edema, as well as quality of life, except in masticatory function, which LLLT showed better effects.
