RESUMO
To determine the effect of a chemo mechanical caries removal [CMCR] gel Carisolv[TM] on shear bond strength [SBS] of conventional glass ionomer cement bonded to human permanent dentin. One conventional glass ionomer cement [Fuji IX, GC Co, Tokyo Japan] was used. Sixty four teeth were sectioned occlusally; exposed coronal dentin was polished with silicon papers. Teeth in the control groups [C] were directly bonded to respective glass ionomer cements [GIC]. For test groups [T] the polished dentin surface was pre-treated with Carisolv [TM] [Singlemix Uncoloured Gel, Medi Team, Sweden] prior to bonding. Bonded specimens were stored for 24 hours and stressed to failure in the shear mode. SBS of Fuji IX, test group [4.97 +/- 0.82 MPa] was significantly higher [P = .001] than its control group [3.98 +/- 0.67MPa]. Carisolv[TM] pre-treatment significantly increased the shear bond strength of conventional glass ionomer cement to dentin
