 This study investigated the effects of four different surface treatments on the morphology, roughness, and biofilm formation of dental titanium implants. The treatments included machining, sandblasting, large grit, and acid etching, SLA, hydrophilic, and hydrophobic. The surface morphology, wetability, and roughness were measured and compared. Additionally, the number of bacteria present on the surfaces was also measured after 48 and 72 hours. The results showed that the hydrophobic surface treated with femtosecond laser had the most significant reduction in bacterial count over time.
