Abstract

Aim: To find possible reagents to minimize inflammatory responses by using an established pulpitis models for the purpose of developing new pulp-capping materials, and to test the possible use of phosphorylated pullulan as a carrier for such an anti-inflammatory reagent. Methodology: Co-culturing was performed using transwell systems. Inflammatory responses were evaluated by measuring cytokines produced by the cells. The effects of two flavonoids, luteolin and quercetin, as anti-inflammatory reagents, and phosphorylated pullulan, which potentially achieves a sufficient marginal sealing to hydroxyapatite and slowly releases luteolin, as a carrier for flavonoids, were tested. Results: Flavonols, particularly luteolin, dramatically attenuated inflammatory cytokine production, which was augmented by co-cultures. Luteolin was successfully enclosed by phosphorylated pullulan. Finally, it was confirmed that luteolin released from phosphorylated pullulan was effective in reducing cytokine production by co-cultures. Conclusions: Combination of phosphorylated pullulan and luteolin could be potentially used in the treatment of dental pulp inflammation.
