Abstract:

BACKGROUND: A large number of cytokines produce in the periodontium on the tension side during orthodontic tooth movement, participate in periodontal remodeling, and make the tooth move to its normal position, thus achieving alveolar remodeling. Heat shock protein 27 (HSP27) is reported to be involved in the periodontal remodeling.
OBJECTIVE: To investigate the expression of HSP27 in the rat periodontium on the tension side during the orthodontic tooth movement.
METHODS: The rat models of orthodontic tooth movement were constructed using NiTi coil spring with the force value of 50 g. The periodontal samples were collected at 1, 3, 5, 7, 10 and 14 days after exerting force to detect the expression level of HSP27 in the periodontium on the tension side.
RESULTS AND CONCLUSION: Immunofluorescence staining results revealed that the expression level of HSP27 in the periodontal tissues began to increase at the 1st day after exerting force, reached the highest level at the 3rd day, and then fell to the initial level at the 5th day. To conclude, HSP27 is evoked by orthodontic force early, and it may play a role in periodontal remodeling.
