An Evaluation of the Occluding Effects of Er;Cr:YSGG, Nd:YAG, CO ₂ and Diode Lasers on Dentinal Tubules: A Scanning Electron Microscope <i>In Vitro</i> Study

Abstract

Our results indicate that Nd: YAG, Er; Cr: YSGG, and CO(2) lasers, through their ability to melt peritubular dentin, can occlude dentinal tubules partially or totally, and therefore reduce patients' hypersensitivity symptoms. The 810-nm diode laser sealed tubules to a far lesser degree, with negligible effects on desensitization.
