Laser-assisted root coverage with de-epithelialized gingival graft(tunneling technique)
CTG preparation can be performed more superficially by DGG(de-epithelialized gingival graft ) to obtain collagen-rich connective tissue from lamina propria of the palatal mucosa .
The findings of Zucchelli et al.’s (2010) study support the observation that CTGs which are presumed to have denser connective tissue are comparatively less prone to post-operative shrinkage.
The advantages of laser applied in this approach are 1)easy de-epithelialization, 2)less bleeding, 3)decreasing post-operative morbidity associated with palatal donor-site surgery, and 4)improving recipient-site wound healing
