Treatment Microwave Disinfection
Non-Disinfected Simulated Disinfection
Control  12.31 ± 0.69 b A  7.73 ± 1.50 c B
Bur abrasion  39.45 ± 3.34 a A 23.06 ± 4.37 a B
Bur grooving  35.77 ± 1.89 a A 17.10 ± 4.99 b B
Monomer etch  14.00 ± 2.70 b A  7.17 ± 4.39 c B

Means followed by different lowercase letters in each column and capital letter in each row differ significantly by Tukey’s test (p<.05).
