dental laser, laser-assisted periodontal treatement, Er:YAG laser, periodontal therapy


In the last decades, dental lasers become a vital part of many dental practices and a solution to many periodontal problems that can be seen in everyday dental practice. Both manual and ultrasonic instruments for scaling and root planing have some shortcomings, their replacement by more appropriate and efficient methods has always been considered in modern dental practice and periodontolgy. This is where the application of LASERs with different wavelengths were inroduced for removing of deposits from the root surfaces. Various types of lasers can also be used in periodontology, including carbon dioxide laser (CO2), neodymium yttrium aluminum garnet (Nd: YAG), Er: YAG and Erbium, Chromium: Yttrium Scandium Gallium Garnet (Er, Cr : YSGG). The main aim of this research is to describe a new therapeutic modality in periodontology- laser assisted periodontal therapy. We searched PubMed for articles relevant to our topic-laser assisted periodontal treatement of studies activating limits like date range (1991-2021), and the type of articles were Clinical Trial, Journal Article, Randomized Controlled Trial, Review, Comparative study and English was chosen as the language and humans as the species. Er: YAG laser is a laser that contains a solid state medium, it is a crystal laser that works in the field of infrared wavelength (2,940 nm). Due to its high absorption in water and hydroxyapatite, several studies have shown the effectiveness of this laser in the ablation of hard and soft tissues and its bactericidal effects with little or no pain in clinical application confirm the numerous advantages of this laser. Er: YAG laser is one of the most spectacular types of laser that can be used in periodontal therapy. Its effectiveness in removing the softened and pathologically altered parts from cement and in smoothing the root surface has been proven in numeorus in vitro studies. The latest scientific evidence suggests that the use of Nd: YAG or Er: YAG wavelengths in the treatment of chronic periodontal disease is equivalent to ustrasound and manual instrumentationof periodontal pockets primarily in terms of reducing the depth of periodontal pockets clinically determined through the probing procedure and by reducing the bacterial population of the dental plaque. However, if increasing of clinical attachment is considered as gold standard in non-surgical periodontal therapy, then the evidence supporting laser-assisted periodontal treatment over traditional therapy is not significant. Clinical parameters such as plaque indices, gingival indices, periodontal pocket depth, bleeding on probing and the occurrence of clinical attachment loss are further improved after treatment with the Er: YAG laser in relation to periodontal pocket mechanical debridman. It is also of interest to note that the use of laser light by the Er: YAG laser in the treatment of periodontal disease alone gives better results than the combination of manual and ultrasound therapy on the root surface of the tooth. The clinical efficacy of the Er: YAG laser is similar to that achieved after mechanical debridman of periodontal pockets. Because the Er: YAG laser has certain advantages, it can be expected to be an alternative choice in the treatment of chronic periodontitis
