RESEARCH FIELD

Research projects are mainly focused on analyze ultra-morphology of dentin organic matrix and in particular collagen, main proteins and proteoglycans as well as their role in relationship with the different treatments currently performed in the procedures of modern adhesive dentistry.
The analysis of the labeling pattern was done using a field emission in-lens scanning electron microscope revealing fine details of the dentin, cement and enamel morphology also without covering samples by conductive layer. The immunocytochemical approach is due to identify and study in fine dentin collagen fibers with each period, representing a new and reproducible method to evaluate the morphology as well as the their structural integrity. By the use of the FEISEM and Transmission Electron Microscopy (TEM), the resarch described the ultra-morphological structure of the dentin organic matrix and in particular is composition by proteins, proteoglycan and sialophosphoprotein.
These techniques are then applied to focused and to investigate the molecular interactions between the dentin organic matrix proteins and some of the most common dental adhesive systems.
