Effect of laser irradiation before scaling or root planing on exposed human cementum

Abstract

We evaluated the effect of various periodontal treatments, which included scaling alone, scaling before and after treatment with YAG and CO₂lasers, root planing alone and root planing before and after treatment using the two lasers.
Evaluation was carried out using an X-ray microanalyzer (XMA), by scanning electron microscopy (SEM), by X-ray photoelectron spectroscopy (ESCA), and by measuring the contact angles in vitro. There was little difference whether irradiation was done before or after treatment, regardless of the method of evaluation.Shika Igaku(J Osaka Odontol Soc) 2003 Dec; 66(4): 339-349.
