  1. (a, b, c: column comparison / x, y: row comparison). (a, b and x, y): The same letters indicate an insignificant difference among the groups (p < 0.05). The a, b and c letters indicate the relationships between the three lines, where measurements based on heat variations are specified. It does not specify the relationships among the groups in terms of varnish or material differences
