Objective: The aim of this study was to prove the role of rice hull liquid smoke (RH-LS) on lymphocytes, macrophages, fibroblasts, interleukin 6 (IL-6), and transforming growth factor β (TGF-β) expression during traumatic ulcer healing.
Materials And Methods: The RH-LS was obtained from the pyrolysis process. Traumatic ulcers were made 10 mm along the labial fornix incisive inferior of Wistar rat using a round stainless-steel blade.
