Figure 2. Survival probability distributions of (a) the dry ground and dry indented [
m = 171.7 (11.7) and 104.6 (11.9), groups A and B, respectively] and wet ground and wet indented [m = 105.7 (12.0) and 80.4 (9.8), groups C and D, respectively] control defect populations for n = 20 specimens per group. m is the mean fracture strength, and the numbers in parentheses are standard deviations highlighting the significant strength reduction on immersion. Survival probability distributions of (b) the dry, wet, acid-etched and acid-etched and silane indented controls [m = 104.6 (11.9), 80.4 (9.8), 79.9 (5.2), and 81.8 (7.0) (groups C, D, I, and J, respectively], highlighting that no effect was evident following acid-etching.
