    Dental adhesives are used routinely in clinic, but there remains a few problems regarding adhesion to dentin and its durability. A new dental adhesive “New Panavia: TPN-S”, isdeveloped by Kuraray Company. TPN-S is proved topossess stronger adhesion todentinand more durable than other adhesives in vitro. Pulpal responses to TPN-S wereinvestigated in vivo (dogs) and there was no problem of pulp irritation with TPN-S.
    The purpose of this study was to evaluate the clinical performances of TPN-S.
    30 patients visited the out-patient department of fixed prosthodontics, Hokkaido University dental hospital for treatment.
    Prosthetic restorations were cemented using TPN-S. Patients were examined 4times; before cementing, immediately after cementing, after 1 week and after 3 months.
    The results lead to the conclusion that TPN-S works excellent clinically.

    Resin-to-resin bonding is achieved by impregnation and diffusion of adhesive monomersto adherend resin following polymerization in situ. Polymer of adhesive is entangled withpolymer of adherend. When pendant double bonds are remaining, copolymerization canoccur. Impregnation of adhesive monomer into adherend polymer is primarily important toobtain stong resin-to-resin bonding.
    The bonding is affected characteristics of adherend resin including crosslinking, fillercontent, water sorption and contamination of the surface. Highly crosslinking restrictsmonomer impregnation. Inorganic filler reduces diffusible polymer area at the interface.The adhesion is adversely affected by water sorption and contamination by waxes, proteins, lipids, etc. When affecting factors are well-controlled, however, dental resin canstrongly join to another resin.
    In addition, mechanical considerations such as joinning form design are important foradhesion with a higher strength.
