Influence of alumina shot blasting induced roughness on bacterial adhesion to titanium.

ABSTRACT:

Objective

To evaluate the influence of different surface roughness levels of titanium disks, induced by alumina blasting, on bacterial adhesion.

Materials and methods

Twelve different surface roughnesses, ranging from 0.01 μm to 6 μm, were produced using a shot blasting technique with varying alumina particle sizes. Surface roughness was measured using confocal interferometry, wettability was assessed by contact angle measurements, and compressive residual stress was evaluated by X-ray diffraction. For each roughness level, 720 samples were used to culture Porphyromonas gingivalis (Gram-negative, anaerobic) and Streptococcus sanguinis (Gram-positive, anaerobic). The colonies formed per unit area, the ratio of dead bacteria to total bacteria, and the metabolic activity for ea
