Effect of Various Laser Systems in Smokers and Nonsmokers With Peri-implantitis: A Randomized, Prospective, Single-Blind Clinical Trial

Objectives: In recent years, a new field of work has been created with the use of laser beam to provide titanium surface decontamination. The aim of this study was to evaluate the effect of various laser systems in smokers and non-smokers with peri-implantitis.

Materials and Methods: According to the study protocol, patients, who were diagnosed with peri-implantitis based on the clinical and radiographic evaluations, were divided into six groups: Group 1: smokers undergoing diode laser application; Group 2: smokers undergoing Erbium, chromium: yttrium, scandium, gallium, garnet (Er, Cr:YSGG) laser application; Group 3: smokers undergoing Erbium:yttrium-aluminum-garnet (Er:YAG) laser application; Group 4: non-smokers undergoing diode laser application; Group 5: non-smokers undergoing Er, Cr:YSGG laser application; and Group 6: non-smokers undergoing Er:YAG laser application. Peri-implant sulcus depth (SD), clinical attachment level (CAL), suppuration, modified plaque index (mPI), gingival index (GI), and modified sulcus bleeding index (mSBI) were recorded and peri-implant sulcus fluid (PISF) was collected to evaluate osteocalcin.
