Clinical and immunological peri-implant parameters among cigarette and electronic smoking patients treated with photochemotherapy: A randomized controlled clinical trial
Abstract
BACKGROUND
Although studies have been done that evaluated the effect of photodynamic therapy (PDT) in cigarette smokers and vapers, however, literature on the impact of these types of smoking on peri-implant parameters lack. The present clinical trial assessed the effectiveness of PDT as an adjunctive therapeutic modality in the treatment of peri-implant mucositis (p-iM) in individuals vaping e-cigs and cigarette smokers.
METHODS
Individuals with p-iM were divided into three groups. (a) Group 1: Cigarette smokers with p-iM (b) Group 2: Vapers (e-cigarette smokers) with p-iM, (c) Group 3: Non-smokers with p-iM. Plaque index (PI), bleeding on probing (BOP) and probing depth (PD) were calculated. Pro-inflammatory biomarkers including matrix metalloproteinase (MMP)-8 and tumor necrosis factor-alpha (TNF-α) were quantified using enzyme linked immunosorbent assay. All assessments were performed at baseline (before treatment) and 12 weeks post treatment. Full mouth disinfection (FMD) was done with the ultrasonic scaler and copious irrigation. The photodynamic therapy (PDT) was done with a diode laser (wavelength: 670 nm, power: 150 mW, density: 1.1 W/cm2). Methylene blue photosensitizer (0.005% concentration) was incorporated inside the periimplant pockets (10 seconds at a depth of 3 mm), and the pockets were irradiated a flexible tip for one minute on the buccal and lingual surfaces. The session of PDT was performed only once at baseline.
RESULTS
Twenty-five cigarette-smokers…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design.
