The biological function of secretory leukocyte protease inhibitor (SLPD is believed to be the inhibition of elastase, cathepsin G and other protease, thereby protecting tissue from self-degradation by these enzyme, Tooth development is associated with morphological and biochernical changes of the dental papilla and enamel organ. Among the proteins involved in the development, some proteases and inhibitors have important role for reorganization of the each developing cells, The SLPI is thought as a regulating protein on the synthesis and degradation of matrix proteins, But there was no report of expression of this molecule on the tooth development, especially on the odontoblast. Therefore, the aim of this study is to verify the role and expression of the SLPI during odontogenesis and rnineralization during mouse tooth development. From in-situ and immunohistochernical analysis, it has firstly described that the SLPI is expressed in odontoblasts during tooth development. Expression of the SLPI was increased in differentiated odontoblast than that of young odontoblast and at the same time, collagen was also observed, From these results, the expression of SLPI in odontoblast may prevent the degradation of collagen through the regulation of MMP, suggesting that the SLPI may play the important roles in odontogenesis and rnineralization.
