Ozone is currently being considered as a possible oral antiseptic agent because it is strongly antimicrobial and does not induce microbial resistance. In the article, we examined the effects of ozone exposure on the production of collagen type-1 and inflammatory cytokines in primary human gingival fibroblasts (HGFs) in vitro using enzyme-linked immunosorbent assays. The addition of 0.5 ppm ozone significantly enhanced collagen type-1 production by HGFs within 24 h. Secretion of the pro-inflammatory cytokines interleukin-6 (IL-6) and IL-8 by HGFs treated with lipopolysaccharide decreased when ozone was present in the medium. Together, these results suggest that clinical use of ozone would facilitate the positive balance between HGF-mediated periodontal tissue maintenance and repair and the stimulation of inflammation and tissue degeneration following exposure to microbial pathogens.
