Full description

Goal: The aim of this study was to evaluate the effects of low-level laser (LLL) after surgical removal of impacted lower third molars (ILTM), including pain level, postoperative facial swelling, trismus and non-stimulated saliva secretory immunoglobulin A (sIgA).

25 participants in 2 patient groups

Laser

Experimental group

Description:

Subsequently to the suture, laser was applied in the right or left side randomly on each patient, according to a sheet of randomization. GaAlAs laser (AMD Picasso, Dentsply Sirona, York, Pennsylvania, USA) with a wavelength of 810 nm was placed intraorally, at a distance of 1 cm in the position of the extracted tooth socket and circling in a 2 cm - diameter area. The power applied was 0.5 ± 20% W, continuously for 30 s. The total real energy released was 12.8 J and the real energy density applied was 4 J/cm2.

Treatment:

Device: GaAlAs laser

Non-laser

No Intervention group

Description:

Every patient, on the control side, the same handpiece was applied intraorally, but laser was not activated
