Comparison of Er,Cr:YSGG laser to minimally invasive surgical technique in the treatment of intrabony defects: Six‐month results of a multicenter, randomized, controlled study

Abstract

Background: The purpose of this publication is to report on the six-month clinical results and patient-reported outcomes (PROs) comparing the surgical use of the erbium, chromium-doped:yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser (ERL) and minimally invasive surgical technique (MIST) for the treatment of intrabony defects in subjects with generalized periodontitis stage III, grade B. Methods: Fifty-three adults (29 females and 24 males; aged 19 to 73 years) with 79 intrabony defects were randomized following scaling and root planing (SRP) to receive ERL monotherapy (n = 27) or MIST (n = 26). Recession, probing depth (PD), clinical attachment level (CAL), treatment time, and PROs were assessed and compared for each treatment group. Clinical measurements were recorded at baseline, 4 to 6 weeks following SRP, and 6 months following surgical therapy. Results: The following primary and secondary outcome variables were noninferior with the following margins: CAL with a non-inferiority margin of 0.6 mm (P = 0.05), PD with a non-inferiority margin of 0.5 mm (P = 0.05). Recession with a non-inferiority margin of 0.4 mm (P = 0.05). Faster procedure times were found for ERL (16.39 ± 6.21 minutes) versus MIST (20.17 ± 5.62 minutes), P = 0.0002. In the first 2 to 3 days of post-therapeutic diary outcomes, subjects reported less bruising, facial swelling, and use of ice pack for the ERL group. Conclusions: This is the first multicenter, randomized, masked, and controlled study demonstrating the ERL is not inferior to MIST in terms of clinical outcomes but is superior in PROs for the surgical treatment of intrabony defects.

Evaluation of Surface Change and Roughness in Implants Lost Due to Peri-Implantitis Using Erbium Laser and Various Methods: An In Vitro Study

“…An RFPT5 radial firing fiber tip with beam divergence > 40 degrees and 0.5 mm in diameter was used in the study. The spot area was calculated as 2.5 mm 2 (0.025 cm 2 ) at 1 mm from the implant surfaces [ 38 ].…”

Clinical evaluation of Er,Cr:YSGG laser therapy used as an adjunct to non‐surgical treatment of periodontitis: Twelve‐month results from a pilot study

“…Erbium laser ablation wounds heal rapidly because of very little thermal effects, shallow penetration depth, minimal tissue damage, and a low inflammatory response 22 . The Er,Cr:YSGG laser with a wavelength of 2780 nm and the Er:YAG laser with a wavelength of 2940 nm, are erbium lasers shown to be useful for nonsurgical and surgical periodontal therapy 23–25 …”

“…22 The Er,Cr:YSGG laser 1 with a wavelength of 2780 nm and the Er:YAG laser with a wavelength of 2940 nm, are erbium lasers shown to be useful for nonsurgical and surgical periodontal therapy. [23][24][25] The purpose of this study was to compare the clinical effectiveness of adjunctive Er,Cr:YSGG laser therapy with SRP versus SRP alone in the treatment of moderate to severe chronic periodontitis. The null hypothesis is no difference in periodontal probing depth (PPD) reduction between treatment groups.…”

Efficacy of the Er,Cr:YSGG Laser Application Versus the Conventional Method in Periodontal Flap Surgery: A Split-Mouth Randomized Control Trial

“…They also reported more favorable patientreported outcomes of the laser treatment. 30 Previously, the clinical effectiveness of a different wavelength of Erbium lasers, the Er:YAG (2940 nm), has been studied for performing a surgical periodontal flap treatment, and its superiority in long-term reduction of PD and gain in attachment compared to the conventional surgery has been reported. 7 However, to our knowledge, this is the first study using an Er,Cr:YSGG laser as a tool for the entire procedure of periodontal flap surgery and comparing it to a conventional open flap debridement procedure.…”
