Abstract:

Objective To investigate the function and expression of tartrate-resistant acid phosphatase（TRAP）during the stage of physiological resorption of the second primary molar of rabbits in the roots, surrounding the permanent dental germ and the peripheral tissue. Methods Rabbits of different days of 0, 4, 10, 16, 22 were selected as objects. Mandible was used for observing and taking the X-ray, and the roots and peripheral tissue of primary molar teeth for paraffin slicing and hematoxylin and eosin, TRAP dyeing and cell counting. Results The root resorption started on the fourth day and root was absorbed 1/3, 2/3 on the 10th and 16th day, to day 22, the shedding occur normally also the permanent tooth erupted. TRAP-positive cells were initially detected in the portion of the dental follicle of the permanent tooth at day 0 postnatal. During 4-10 days postnatal, the number of TRAP-positive mononuclear and multinucleate odontoclasts on the root surface gradually increased but decreased to day 16. Conclusion The regularity in the expression of TRAP during the stage of physiological resorption matched the result of X-ray observation. TRAP-positive cells initially detected in the portion of the dental follicle of the permanent tooth may play an important role in the mechanism of physiological root resorption.
