Abstract

Background: Combustible tobacco use is generally linked with accelerated periodontal bone loss and diminished post-surgical wound healing; however, the pathogenesis of this process at the cellular level remains unclear. Nicotine is known to affect human gingival fibroblast orientation, attachment, and β1 integrin expression, yet little is known about its effects on osteoclasts, the cells most responsible for bone resorption. The purpose of this study was to determine the effects of physiologically relevant nicotine levels on porcine osteoclast function as measured by resorption of calcium phosphate. Methods: Pure nicotine was diluted in medium to the following concentrations: 0.03 μM, 0.15 μM, 0.30 μM, 0.60 μM and 1.50 μM. Porcine osteoclasts were seeded onto calcium phosphate multi-test slides and incubated at 37°C with half media changes every 24 hours. Cells received 0, 0.15, 0.30, 0.60, and 1.50 μM nicotine, or 25 nM parathyroid hormone (PTH). Osteoclast resorption was quantified by measuring the resorbed surface area of the calcium phosphate substrate. Results: Osteoclast cultures resorbed bone slices and calcium phosphate substrate. All nicotine concentrations and PTH resulted in statistically significantly greater mean percent resorptions than the control group (P <0.05). However, no statistical difference was found between the various nicotine doses or PTH. The number of osteoclasts increased in a linear relationship to the increasing nicotine concentrations; however, no correlation was found between osteoclast number and the amount of resorption. Conclusions: Nicotine is non-toxic to osteoclasts at the clinically relevant levels tested. Nicotine appears to stimulate osteoclast differentiation and resorption of calcium phosphate, the major component of bone. Nicotine-modulated osteoclast stimulation may, in part, explain the increased rapidity of periodontal bone loss and refractory disease incidence in smokers.
