Chemo-Mechanical Approach to Improve Repair Bond Strength of Denture Teeth

Table 2

Mean shear bond strength ± SD (MPa) and significance of repaired specimens with different surface treatments at 0 and 5,000 thermal cycles.

Treated side	Group	0 thermal cycles, mean ± SD	5,000 thermal cycles, mean ± SD
No treatment	Control	9.78 ± 0.81	6.97 ± 0.50
Base	B-AB	17.02 ± 1.00^a	15.74 ± 0.72^a
	B-AB + SCA	21.59 ± 1.10	18.61 ± 0.76^b

Groups with similar letters are not significantly different from each other. Vertically identical superscripted small letters denote no significant differences among groups . Horizontally identical superscripted capital letters denote no significant difference after thermal cycling within the surface treatment group .
