The present study was aimed to evaluate and compare the compressive strength of
conventional glass ionomer cement with resin modified glass ionomer, compomer and
microhybrid composite. A total of 40 specimens of esthetic restorative materials were
fabricated using customized cylindrical teflon mould measuring 6mm height and 4mm
diameter and were grouped with ten specimens in each group, Group I: Conventional
glass ionomer cement (Fuji II). Group II: Resin modified glass ionomer (Fuji II LC).
Group III: Compomer (Dyract AP) and Group IV: Microhybrid composite resin
(Tetric Ceram).They were covered with Mylar strip and were cured using LED light
curing unit. Compressive strength was evaluated using Universal testing machine. The
result showed that there were a significant difference among the groups in which
Tetric Ceram showed highest compressive strength and Fuji II showed the least
compressive strength
