The impact of laser application on periodontal and peri‐implant wound healing

American Academy of Periodontology Statement on the Efficacy of Lasers in the Non‐Surgical Treatment of Inflammatory Periodontal Disease

“…[10][11][12][13][14][15][16][17] The available evidence consistently shows that therapies intended to arrest and control periodontitis depend primarily on effective debridement of the root surface and not removal of the lining of the pocket soft tissue wall, i.e., curettage. 18,19 Currently, there is minimal evidence to support use of a laser for the purpose of subgingival debridement, either as a monotherapy or adjunctive to SRP.…”

“…18,19 Currently, there is minimal evidence to support use of a laser for the purpose of subgingival debridement, either as a monotherapy or adjunctive to SRP. [10][11][12][13][14][15][16][17][18][19][20][21][22] REDUCTION OF SUBGINGIVAL BACTERIAL LEVELS Current evidence shows lasers, as a group, to be unpredictable and inconsistent in their ability to reduce subgingival microbial loads beyond that achieved by SRP alone. [10][11][12][13][14][15][16][17] Further, this conclusion also appears to apply to the use of photodynamic therapy (PDT), either as a monotherapy or adjunctive to SRP.…”

“…The Er:YAG laser has been shown, in vitro, to remove calculus 12 and to negate endotoxin. 12,15,24,25 There is the potential for root surface damage during the process of in vivo calculus removal since the Er:YAG is a hard tissue laser and the operator would not be able to visualize what is being lased. Clinical data on attachment level changes when compared to SRP alone are conflicting, with some studies showing a slight benefit while others show no benefit.…”

“…[10][11][12][13][14][15][16][17][18] The primary purpose of this statement is to provide an evidence-based perspective on three of the purported benefits of using lasers in the nonsurgical treatment of periodontal disease, i.e., sulcular and/or pocket debridement (a.k.a. laser curettage), reduction of subgingival bacterial loads (a.k.a.…”

Superpulsed laser therapy on healing process after tooth extraction in patients waiting for liver transplantation

“…Little evidence is available concerning the influence of monochromatic light on either periodontal or peri-implant wound healing, derived from experimental animal studies and randomized controlled clinical trials [14], and the benefit over conventional treatment procedures is in doubt.…”
