Over the years, the use of the laser within health field and more particularly dentistry has been increasing and improving. The application of laser in the periodontal treatment takes part of a non-surgical and surgical approaches, is used for the decontamination of periodontal pockets due to its bactericidal effect, and the removal of granulation tissues, inflamed and diseased epithelium lining, bacterial deposits and subgingival calculus. However in spite of all the marketing surrounding, the use of laser highlighting its beneficial effect, the capacity of laser to replace the conventional treatment for chronic periodontitis is still debatable. In fact there is no evidence that any laser system adds substantial clinical value above conventional treatments of chronic periodontitis. Some studies showed a significant positive effect on clinical attachment level gain and probing depth reduction. In the other hand, several articles demonstrated no evidence of the superior effectiveness of laser therapy compared to root planing and scaling. Our aims is to review the literature on the capacity of erbium:Yttrium-aluminum-garnet and neodymium:Yttrium-aluminium-garnet laser to either replace or complete conventional mechanical/surgical periodontal treatments.

Keywords: Laser, Review, Scaling and root planning, Erbium:Yttrium-aluminum-garnet, Neodymium:Yttrium-aluminium-garnet, Periodontitis

Core tip: Faced with the increased use of lasers in dentistry, we tried to demystify, in this review, the real benefits and disadvantages of the use of the neodymium:Yttrium-aluminium-garnet and erbium:Yttrium-aluminum-garnet lasers in periodontics. Many trials showed that the use of lasers is an effective and safe method of root planing in periodontal non-surgical treatment of chronic periodontitis. However, due its possible side effects and less effective results when used alone, lead some authors to state that the use of lasers as a replacement of the conventional mechanical treatment is still doubtful.
