Objective: This study examined the adhesive properties and trial manufacture of resin core shen it is applied to the infected root canal wall. Materials and Methods: The examined resins were: AC-1, AC-2 and AC-3, which contain an acid reaction fluoride inclusion of glass ionomer filler (S-PRG). Evaluations of bonding strength and bonding elasticity were performed. The flow value was calculated and an adhesion test of the resins was performed according to the ISO standard. The bacterial survivability on the root canal wall was analyzed by scanning electron microscope (SEM) and 4', 6-diamino-2-phenylindole dihydrochloride (DAPI). Results: A bacterial survivability on the root canal wall of 76% was confirmed by SEM and DAPI. In addition, a rate of concordance between anaerobiotic culture and DAPI of 86% was exhibited. However, neither infiltration nor pigmentation was observed between the root canal wall and resin core. Suitable seal and absence of gap was corroborated by SEM. The elemental components of the bonding materials were identified by energy dispersive X-ray micro analyzer. Conclusions: The simple confirmation of bacterial survivability by DAPI was effective and the trial manufacture of root canal resin core presented favorable behavior in infected root canal wall with physical properties similar to the dentin. Therefore, the clinical application of these materials could be possible.
