Abstract

This in-vitro study aimed to explore the potential of Diode Laser by quantifying the release of transforming growth factor-beta 1 (TGF-β1), platelet-derived growth factor (PDGF)-BB, and vascular endothelial growth factor (VEGF) from root dentin after ethylenediaminetetraacetic acid (EDTA) and diode laser. In 30 hemi-roots distributed into five groups: G1: Tris-buffered solution (TBS); G2: 17%EDTA; G3: 17% EDTA +650 nm Diode Laser; G4:17% EDTA +810 nm Diode Laser; and G5: 810 nm Diode Laser. The concentration of the three factors was quantified using a cytokine bead array. Statistical tests were performed to estimate intergroup differences (p ≤ 0.05). TGF-β1 and VEGF were solubilised in all test protocols. The ability of low-level power diode lasers to release proteins from the matrix is limited. Its effect on the release of VEGF and PDGF-BB does not make a difference. A synergy between EDTA and Diode Laser led to a greater proportion of TGF-β1 release.
