ABSTRACT
Objective To investigate the expression and distribution of cyclooxygenase-2(COX-2) in periodontal tissues during experimental tooth movement in rats,and study the relationship between COX-2 and vesscular reconstruction in experimental tooth movement process.Methods Thirty-five healthy Wistar rats were divided randomly into 7 groups on averagenormal group and experimental groups for 1,3,5,7,14 and 21 d.A NiTi coil spring with 0.294 N mesial force was connected between first molars of maxillary and the upper incisors.The histological sections were stained with goat anti rat COX-2 antibody,and computer image analysis was used to study the expression of COX-2 in the periodontal tissues of rats.Results Pressure areacompared with normal group(134.75?5.25) the COX-2 expression in 1 d group (147.73?3.27)increased(P0.05).Conclusion The expression of COX-2 in periodontal tissues during experimental tooth movement increase,suggesting that COX-2 can promote the vascular reconstruction in periodontal tissues during orthodontic tooth movement.
