Summary. This study compared the pulpal responses to two innovative semihydrous glass ionomer luting cements (STA 1 and ZIN 2 ) with those previously obtained for a conventional anhydrous giass ionomer luting cement, Aquacem 3 . 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, Kalzinol 4 . 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.
