| Mpa – mega pascals; N – number of specimens; SD – standard deviation; df – degree of freedom; T – time interval; C – control (no aging, 24 hours storage in distilled water at 37 degrees centigrade); 1, 3, 6, 12 – number of months; 1 – 850 cycles equivalent to 1 month; 3 – 2500 cycles equivalent to 3 months; 6 – 5000 cycles equivalent to 6 months; 12 – 10000 cycles equivalent to 12 months of clinical use. Test employed; one way analysis of variance (ANOVA). Statistical significance: All differences at various time intervals in each group were considered to be statistically significant if the probable P value was ≤0.05 | ||||||
