(a) Periodontal ligament (PDL) inflammation marker expression assayed by western blot analysis. Inducible NO synthase (iNOS), interleukin (IL)-1 and cyclooxygenase (COX)-2 expression are prominent at day 1 and decrease by days 5 and 7. Matrix metalloproteinase (MMP)-3 expression showed a significant increase at day 7. (b) Quantification of PDL cell inflammation markers in the MA group under different experimental conditions. (c) Quantification of PDL inflammation markers in the MB group under different experimental conditions. *The statistically significant difference of the highest value of all tested experiments (p<0.05).
