Abstract:
Objective:To observe HSP70 expression during experimental tooth movement in rats.Methods:Orthodontic appliance was placed between the maxillary right first molar and maxillary central incisors of 30 adult SD rats.The rats were killed at 1,3,5,7,14 d after orthodontic force application,samples of experimental teeth with periodontal tissue were prepared for immunohistochemical examination of HSP70 expression.Result:Strong expression of HSP 70 in periodontal ligment was observed at 1 and 3 d after orthodontic force application,positive at 5 d and weak positive at 7 and 14 d.Conclusion:HSP 70 is expressed in periodontal ligment at different levels in different stages during orthodontic tooth movement.
