The resin cement forms the weakest link for a ceramic restoration. This was found in an investigation of the de-bonding of resin cementation of zirconia or lithium di-silicate ceramic to bovine dentin.
Previously, we have reported data obtained from near-infrared reflection spectroscopy (NIRS) used to non-invasively monitor tissue changes after optical exposure. The results indicated that oral mucosa may be more sensitive than skin to blue light. In this pilot study, visible data from NIRS (VNIRS) was used to observe differences between exposure groups with respect to the following parameters: pigmentation (melanin index; MI), blood oxygenation (OX) and erythema (erythema index; EI).
The aim of the study was to investigate the bond strength of a silica glass-fiber-reinforced composite to polymer teeth compared with the bond strength of a proprietary heat-polymerized denture base polymer and also between a layer of the polymerized matrix polymer of the experimental base material and an additional layer of the same material.
This study was undertaken to determine the potential of dental adhesive products to induce mucosal irritation based on their ability to damage the blood vessels of the chorioallantoic membrane (CAM) in fertilized hen’s egg.
