치수 석회화 변성과정에서 단백분해효소 및 단백분해효소 억제제의 역할

다국어 초록 (Multilingual Abstract)

As pulp calcification occurs at least fifty percent of total teeth, the focal calcification in pulp chamber usually appears in all age groups. However, the pulp calcification is one of the important pathologic changes affecting the pulp vitality. In order to elucidate the mechanism of pulp calcification during the retrogressive degeneration of pulp tissue we performed an immunohistochemical study for proteases (MMP-3, MMP-10, and cathepsin-G), antiproteases (TIMP-1, α1- AT) and proteins involving tissue protection (TGase-2 and HSP-70). In the normal pulp tissue MMP-3 and MMP-10 were weakly expressed, but cathepsin-G and TIMP-1 were rarely expressed. Around the calcifying tissue of MMP-3, MMP- 10, and α1-AT were predominant, but TIMP-1 and cathepsin-G were sparsely expressed. On the other hands, TGase-2 and HSP-70 were condensed in the proximal fibrous tissue. These data suggest that the pulp calcification is related to retrogressive pulp degeneration, which could be resulted in the incomplete digestion of the degenerated stromal tissue by different proteases. We presume that the aberrant protease digestion of chronic pulpal pathosis, i.e., sclerotic fibrosis, chronic pulp degeneration, etc., may enhance the dystrophic calcification in dental pulp.
