Laser

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.

Group Type EXPERIMENTAL

GaAlAs laser

Intervention Type DEVICE

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. Each patient was irradiated 3 times consecutively right after surgery, day 1 and day 2 after surgery

Non-laser

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