A qualitative measurement of surface wettability of the treated dental
screws (ZT and ZTM) was performed by sample immersion in water
or water/red ink mixture followed by the observation of the water meniscus
around the sample and also of the wetted sample surface. Images
(Olympus digital camera) and videos (20 s, 300 images/s, FTA1000,
Drop Shape Instrument, Fotocamera Prosilica CG) of the wetting process
were acquired.
