Abstract:

The cementum, a mineralized tissue lining the tooth root surface, is required for development of a functional periodontal ligament. The presence of healthy cementum is considered to be an important criterion for predictable restoration of periodontal tissues lost as a consequence of disease. Despite the importance of cementum to general oral health, very little is known about the cells responsible for the formation of cementum, cementoblasts. The aim of this study was to examine the effect of the ionic products from the dissolution of bioactive glass with 60% of silica ( BG60S ) on the behavior of cementoblasts, osteoblasts and fibroblasts. The cell viability was tested by MTT assay based on mitochondria activity of the cell and Trypan Blue assay based on membrane cell viability. The membrane cell viability measured by Trypan Blue assay showed the beneficial effect on all the cell types tested. It was observed a higher proliferation in the presence of ionic products from dissolution of BG60S when compared to control. In the MTT assay we also observed increased cell viability on all the cell types, but proliferation of cementoblasts was higher (107%) than observed for the other cells (104%) compared to control. The results from this study suggest that Cementoblasts, osteoblasts and fibroblasts are important cells on events that control the development of mineralizing and not mineralizing tissues and the investigation of the comparative behavior of these cells can be a useful experimental model. The observed effect of the bioactive glass particles on cementoblasts shows that this material is an interesting alternative to be used in composite membranes for cementum tissue engineering.
