Gp – group; M – mean adhesive failure stress; p – probability. Codes used for cements: GI – glass ionomer; PC – polycarboxylate; RC – resin cement; RGI – resin modified glass ionomer; ZP – zinc phosphate. Test employed – student ‘t’ test; level of the degree of significance was determined on the value of p < 0.05; * significant; ** highly significant. |
