Antimicrobial Efficacy of Different Decontamination Methods as Tested on Dental Implants with Various Types of Surfaces

Abstract

Departmental sources Background:Peri-implantitis is an inflammatory reaction affecting both hard and soft tissues surrounding dental implants. This pathological condition is caused by a polymicrobial aggressive biofilm that colonizes the implant and abutment surface at the peri-implant crevice level. The present in vitro study evaluated different methods of implant surface decontamination and assessed whether the type of the implant surface influences the results. Material/Methods:The study was conducted in an in vitro model of peri-implantitis using 30 implants. The implants were divided into 3 equal groups based on the surface characteristics: machined-surface, sand-blasted and acid-etched, and HA-coated. Implants were coated with E. coli biofilm. After an incubation period, they were decontaminated with 4 different methods: sonic scaler application, sonic scaler application with the chemical agent Perisolv ® combination, Er: YAG laser treatment, and PDT therapy with methylene blue as a photosensitizer. Results:The highest level of decontamination was achieved for machined-surface implants and for the combined chemical-mechanical and Er: YAG laser treatment. Conclusions:The results of our study suggest that the method of implant decontamination should be customized to the type of implant surface.

Assessment of Human Gingival Fibroblast Proliferation after Laser Stimulation In Vitro Using Different Laser Types and Wavelengths (1064, 980, 635, 450, and 405 nm)—Preliminary Report

“…It is used, for instance, in orthodontics, in the treatment of temporomandibular joint dysfunctions and implantological rehabilitation [5][6][7][8][9]. Moreover, lasers have been demonstrated to support the treatment of snoring and sleep apnea, as well as periodontal diseases, e.g., peri-implantitis [10][11][12][13][14][15][16][17]. The effects of laser photobiomodulation (PBM) in muco-gingival surgery are relatively well established [18][19][20].…”

“…The decontamination of the implant surface is also of fundamental importance. This procedure is useful for prosthetic loading and to minimize peri-implantitis, which is the main cause of implant failure [ 36 ].…”

Photodynamic Therapy (PDT) in Prosthodontics: Disinfection of Human Teeth Exposed to Streptococcus mutans and the Effect on the Adhesion of Full Ceramic Veneers, Crowns, and Inlays: An In Vitro Study

“…Using tissue regeneration laser settings, as well as the addition of methylene blue as a photosensitizer and its washing with Kaqun water, represents an atypical protocol of PDT. Other studies have shown the effectiveness of various standard PDT protocols on both aerobic and anaerobic bacterial species [ 27 , 28 , 29 , 30 ]. The selection of the photosensitizer (MB) and laser power (100 mW) was based on previous works that demonstrated their efficacy [ 4 , 21 , 30 ].…”
