Abstract:
BACKGROUND:To dynamicaly monitor the varying levels of inflammatory factors in the gingival crevicular fluid is helpful to assess the early effect of orthodontic tooth movement. Myeloperoxidase, soluble intercelular adhesion molecule-1, pentraxin 3 are proven to be closely related to inflammation, but it is unclear about the levels of these three kinds of inflammatory factors as wel as association of these three kinds of inflammatory factors with orthodontic tooth. OBJECTIVE:To detect the expression levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid during maxilary canine distal movement and to assess their correlation with periodontal disease, canine movement distance and orthodontic force. METHODS:Twenty-one orthodontic patients were enroled and assigned into 150 g (n=12) or 100 g (n=9) groups according to orthodontic force. The gingival crevicular fluid samples of orthodontic patients were colected before and at 4, 12, 24 hours, 7, 14 days after maxilary canine distal movement. Levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid were measured and analyzed using ELISA assay. RESULTS AND CONCLUSION: During the distal movement of maxilary canine, under orthodontic force, the level of myeloperoxidase was peaked at 4 hours and then decreased, while the expression level of soluble intercelular adhesion molecule-1 was peaked at 12 hours, and then decreased. Both myeloperoxidase and soluble intercelular adhesion molecule-1 levels returned to normal at 7 days under orthodontic force. The expression level of pentraxin-3 was increased significantly under orthodontic force, peaked at 24 hours, and then decreased gradualy to the normal level at 7 days. In addition, the expression levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid were significantly higher under 150 g force than under 100 g force. These findings indicate that detecting varying levels of myeloperoxidase, soluble intercelular adhesion molecule-1 and pentraxin-3 in the gingival crevicular fluid is useful to assess the efficiency of orthodontic treatment and prevent adverse reactions.
