Abstract:
Objective To observe the dynamic changes of aspartate transaminase(AST ) in gingival crevicular fluid on tooth movement in new bone area after distraction osteogenesis at different time .Methods The distraction osteogenesis surgical proce‐dure was performed in 8 beagle dogs without periodontal disease and normal teeth ,experimental teeth were transplanted into the bone regeneration area after 2 weeks and after 6 weeks .Comparative analysis AST of each time (1 ,2 ,3 ,7 ,14 ,28 d after distraction) dynamic changes in gingival crevicular fluid .Results The AST level of gingival crevicular fluid in experimental tooth was rising for the first three days ,and the group of two weeks were significantly higher than 6 weeks ;AST levels after 7 d showed a trend of de‐cline ,down to the lowest point at 21 d ,and gradually restored ,AST levels reached a higher level again in the 28 d .Conclusion The AST level of experimental teeth increased significantly after 2 weeks than after 6 weeks ,but over time the AST level change is not linear ,this change has certain guiding significance for the clinical research in the future .
