Abstract:

BACKGROUND: Orthodontic treatment has a long course and referral interval, which is an important difficulty. How to accelerate orthodontic tooth movement is an issue of concern.
OBJECTIVE: To testify whether the local injection of AMD3100 (CXCR4 antagonist) can accelerate the tooth movement or not, and to explore the role of stromal cell-derived factor 1/CXC chemokine receptor axis in tooth movement.
METHODS: Ninety Sprague-Dawley rats aged 8-10 weeks old were selected and the models of orthodontic tooth movement were established. The model rats were randomized into three groups, and then given the injection of stromal cell-derived factor 1, AMD3100 or PBS. The rats were killed at 1, 3, 5, 7, 10 and 14 days to measure the tooth movement distance.
RESULTS AND CONCLUSION: The tooth movement distance showed difference among three groups; AMD3100 could facilitate the tooth movement, while stromal cell-derived factor 1 exerted inhibitory effect on the tooth movement. To conclude, stromal cell-derived factor 1/CXC chemokine receptor axis plays an important role in tooth movement.
