Mean (SD) for contact angle measurements
| Contact Angle |
||
|---|---|---|
| Group | Polished* | Unpolished |
| L199 | 73.7 (3.3) | 78.8 (4.1) |
| E-10 | 71.3 (2.5) | 76.0 (3.4) |
| E-15 | 71.8 (3.9) | 75.6 (4.6) |
| E-15+XL | 68.7 (2.9) | 76.9 (2.9) |
| E-20** | 68.6 (4.2) | 68.5 (3.3) |
Polished surfaces had significantly (P<.001; 2-way ANOVA) lower contact angles than unpolished specimens.
E-20 had significantly (P=.039; 2-way ANOVA and post hoc Tukey test) lower contact angle than other groups.
