In Vivo Early Plaque Colonization On Smooth Titanium Surface, A. Carrassi, A. Sardella, L. Rimondini

Cells and Materials

Plaque development on pure titanium in a 24-hour period is described in an in vivo human model. Stents with titanium and root cementum specimens were applied to volunteers, who suspended oral hygiene procedures for 24 hours. The specimens were removed at 2, 4 and 24 hours and studied with a scanning electron microscope. A global area of 240 µm x 300 µm, composed of the sum of twelve 20 µm x 25 µm fields randomly selected, was examined for each specimen. The presence of cocci, short rods, long rods and bacterial aggregation, and bacteria density was recorded for each field. …
