To in vitro investigate the effect of different implant surface decontamination methods and treatment storing conditions on implant surface morphology and cell viability. Titanium disks with a sand-blasted and acid-etched surface (Promote, PRO) were treated with diamond polishing brushes (BRUSH), nickel-titanium brushes (NITI), or phenol and sulfuric acid-gel (GEL). The disks were stored in saline (-S) or left exposed to air overnight (-A). Untreated (PRO) and machined (MACHINED) disks were used as controls. GEL samples were treated for the 60 s, while the operative time was recorded for BRUSH and NITI. The samples were subjected to scanning electron microscopy (SEM), surface roughness measurements, and cell viability (SaOS-2 cells, 7 days) assessment. The operative time was shorter for NITI than for BRUSH (p = 0.017). The original surface morphology (PRO) was not altered in the GEL group, in contrast with what was observed for BRUSH and NITI. The type of storage did not influence the surface morphology. No significant differences in Sa and Sz were observed among the groups, except for MACHINED, which presented lower Sa values (p
