Laser Tongue Debridement for Oral Malodor

10-minute treatment with the Waterlase Express (Biolase, Irvine CA). The dorso-posterior surface of the tongue is treated with the laser in 10 passes of 60 seconds each with 10 seconds of rest in between. Laser settings were 60μs pulse width, 4W, 40Hz, 10% air and 5% water irrigation. An MC12 sapphire laser tip (Biolase, Irvine CA) is held 3mm away from the tongue in a constant sweeping motion during treatment with passes overlapping passes in alternate direction, side to side motion and front to back motion with laser fluence on the tongue surface calculated at 3J/cm2. The settings were non ablative and non thermal.
