Purpose.
The aims of this in vitro study were to evaluate morphological changes induced by glycine powder air-polishing on titanium surfaces, biofilm removal, and biocompatibility.
Material and Methods.
Titanium grade IV discs were allocated into two groups: (1) discs without biofilm and (2) discs for Streptococcus mutans biofilm formation.
Discs in each group were further subdivided into (a) no treatment and (b) air-polishing treatment with glycine powder.
Discs were characterized by scanning electron microscopy (SEM), electron-dispersive spectroscopy (EDS), and confocal microscopy.
Bacterial biofilms were quantified using a crystal violet dye-binding assay.
Biocompatibility was evaluated by measuring the coverage and viability of L929 fibroblast cells cultured on the discs.
Results.
Air-polishing increased the roughness of treated discs (P<0.05).
EDS analysis did not show significant differences in the chemical composition of treated and nontreated discs.
The amount of residual biofilm on treated discs was 8.6-fold lower than untreated controls (P<0.05).
Coverage of treated discs by fibroblasts was half that of untreated discs (P<0.05) although both groups had the same cell viability.
Conclusions.
Air-polishing removed a significant amount of biofilm from titanium surfaces.
The “polishing” was accompanied by increased surface roughness, but there were no changes in chemical and elemental compositions, nor the biocompatibility.
