Reactionary and reparative dentinogenesis: A review
No full textMany attempts have been made in the last fifteen years for the better understanding of molecular mechanisms underlying dental tissue response to an injury i.e. caries, dental trauma, restoration and/or preparation, providing for new dentin formation, tertiary dentin. Tertiary dentin represents dental tissues of two variants “reactionary” and “reparative” ones, sharing the inductive nature but characterized by different healing processes, related to the extent of tooth injury. This paper discusses the current knowledge about tooth response to injury by reviewing the literature

The immunohistochemical outline of p27kip1, cyclin B1 and cyclin D3 in pleomorphic adenomas.
No full textAIM: Pleomorphic adenomas of salivary glands are benign lesions which may sometimes relapse even after complete surgical removal. This risk has led to the search for methods to provide predictive data on the biological behaviour of such neoplasia. The authors intend to evaluate the degree of cellular aggression of these tumours by finding prognostic data using the antigens involved in cellular proliferative activity. Therefore they have chosen for this study: p27kip1, cyclin B1 and Cyclin D3. METHODS: Seventeen mixed tumours, 2 of them relapsed, underwent the direct immunohystochemical PAP technique for the determination of antigens p27kip1, cyclins B1 and D3 of the tissue. RESULTS: The results obtained show that the verification of these markers may reveal a potential risk of biological deviation and that their expression is independent of the degree of cellularity in neoplasias. CONCLUSIONS: On the basis of the results, the conclusion is drawn that there is no relation between the expressivity of the mentioned antigens and histological characters of pleomorphic adenomas
