Abstract
Summary. This study compared the pulpal responses to two innovative semihydrous glass ionomer luting cements (STA1 and ZIN2) with those previously obtained for a conventional anhydrous giass ionomer luting cement, Aquacem3. ZIN contained zinc oxide in the formulation. The study was conducted according to the BSI (1989) recommendations for testing restorative materials in vivo. ZIN was associated with minimal pulpal changes and mtcrobial microieakage, and differed little from the control material, Kalzinol4. The pulpal response to STA was similar to that observed for Aquacem, but was associated with less microbial microieakage. The statistical model demonstrated a significant association between bacterial presence within the experimental cavity and pulpal inflammation. The closer that bacteria were to the pulp, the more severe was the ensuing inflammation.
