Bone Response to Titanium Implants Coated with Double- or Single-Stranded DNA

Table 1

Surface roughness (Sa) and contact angle (θ) of specimens.

Specimen	Sa (μm)	θ(°)
Ti	0.30	74.42
DNA-d/protamine	0.64	49.14
DNA-s/protamine	0.53	44.92

Values in parenthesis indicate SD.
Different letters indicate significant difference in Sa or in contact angles among Ti, DNA-d/protamine, and DNA-s/protamine implants (p < 0.05).
