Abstract:
Objective: To investigate the expression of CSF-1 and TGF-?1 in periodontal tissue of third premolar germ during second primary molar orthodontic movement in dog. Methods: Orthodontic appliance with the force of 0.784 N for the mesial movement of mandible second primary molar was used in 4 dogs for 14 d.Then the samples including mandibular second and third molars and surrounding tissues were prepared for CSF-1 and TGF-?1 detection by immunohistochemical staining technique. Results: Strong CSF-1, TGF-?1 expression was found in the dental follicle and alveolar bone of mesial part of third premolar germ, and weak in the dental follicle and alveolar bone of distal part of third premolar germ in the treated side of the dogs. Conclusion: CSF-1 and TGF-?1 may play roles in the bone remodeling for orthodontic primary tooth movement.
