RESUMO
Objective: Diode laser has a wide range of wavelengths that may render the absorption effect and interaction with the tissue is different. Based on available evidences, the aim of this review is to critically evaluate the use of different diode laser wavelengths in the treatment of mucocele. Materials and methods: The literature of clinical case studies for the past 8 years has been considered. Literature search and selection, data extraction and methodological quality assessment, data analysis and interpretation, and drafting and revision have been performed. Both authors have read and approved the final article. Results: This review has aimed at detecting the experience on the background and at giving a critical summary of the clinical cases literature. Previous results of controlled clinical case reviews in this field as well as in basic research pointed to a potential of the diode laser in the surgical removal of mucocele. Initial clinical results showed that diode laser surgical therapy positively influences the post-surgical wound healing. All diode laser wavelengths do not show much difference in the acceleration in epithelial regeneration, and the healing of the wound takes some time by all wavelengths. They can reduce the need for anesthesia or wound care and therefore reduce the fear of the patient. Conclusions: The procedure in the most reviewed clinical cases took place within a few minutes and thus required no more time than a conventional surgical intervention with conventional surgical instruments. Since all surgical steps are carried out with the same instrument, there is no need for sutures and only one handpiece is sterilized. Due to the contactless preparation and the lack of vibrations as well as the elimination of the anesthesia, the entire process is much more pleasant for the patient and thus indirectly for the practitioner, because a relaxed patient can simply be better treated.

Objective: The purpose of this literature review was to evaluate the effectiveness of using Er:YAG (erbium-doped yttrium/aluminum/garnet) laser or Er,Cr:YSGG (erbium, chromium-doped yttrium/scandium/gallium/garnet) laser on calculus removal and their effect on the topography and roughness of root surface in comparison with the conventional instruments in the nonsurgical periodontal therapy. Background data: One of the most challenging problems in treatment of periodontal disease is the elimination of plaque and calculus, leaving a clean and smooth root surface to decrease plaque and calculus retention, and for good gingival reattachment. Materials and methods: PubMed and Google Scholar were searched for available literature. The electronic search was limited to articles published in the period between January 2007 and April 2017, in the English language. Results: A total of 47 publications fulfilled the inclusion criteria of this systematic review and screened according to the research questions. Calculus removal using the ultrasonic instrument showed remaining calculus compared with the hand instrument, whereas, on the contrary, erbium lasers revealed no remaining calculus or smaller amounts compared with the conventional instruments when used in appropriate settings. The results of this review showed that ultrasonic instrumentation produced effects on the root surface almost similar to that of hand instrumentation. Er:YAG laser and Er,Cr:YSGG laser clarify a little more surface roughness when compared with conventional instruments. Conclusions: The present systematic review indicates that a combination of scaling and root planing (SRP) using the erbium lasers as an adjunctive therapy at certain parameters can be appropriate to remove residual debris from the root surface and at the same time have little or no negative thermal effect on the root surface. The Er:YAG laser also seems to be the most suitable for nonsurgical periodontal therapy. Additional new good-designed studies are needed to evaluate the effectiveness of erbium lasers with SRP in nonsurgical periodontal therapy.
