Abstract
Objectives: To investigate the effect of nicotine on the healing of an oral cavity wound, high and low concentrations of nicotine were administered on human gingival fibroblasts.
Methods: Nicotine at concentrations of 0.1, 1, 5, and 10 mM were administered to gingival fibroblasts to evaluate the survival capability of the cells. Nicotine at 0.1 mM, a nonapoptotic concentration, was administered to evaluate apoptosis using Annexin V-FITC/Propidium Iodide cell staining. Nicotine at 1, 10, and 100 mM were administered to measure the expression of inflammatory cytokines, which was measured by RT-PCR and ELISA. FGF was treated with an additional 1, 10, or 100 mM of nicotine to evaluate cell proliferation and wound healing.
Results: As the concentration of nicotine increased (0.1, 1, 5, and 10 mM), the survival capability of the cells reduced. When cells were exposed to low nicotine concentration (0.1 mM) for 24 h, apoptosis occurred. Moreover, if the cell was exposed for 48 h, cell apoptosis occurred with necrosis. As the concentration of nicotine increased (1, 10, and 100 mM), more inflammatory cytokines were expressed. When EC LPS and TF LPS were combined with a low concentration of nicotine (1 and 10 mM), the expression of inflammatory cytokines was suppressed. The FGF level decreased as the nicotine concentration increased (1, 10, and 100 mM).
Conclusions: Nicotine interferes with the wound healing process of gingival fibroblasts. To maintain the wound healing process after a surgery or dental procedure, cessation of smoking is recommended.
