Introduction: Implants have evolved in terms of shape, size, and surface in order to optimize the success rate. Exploring the antioxidant levels around different surface treated dental implants is essential for improving their performance. The purpose of this study was to detect and measure the level of superoxide dismutase (SOD), an antioxidant enzyme among SLA, SLActive and TiUnite implant surfaces. Materials and Methods: Subjects with healthy dental implant were categorized into Group 1: SLA (n=25), Group 2: SLActive (n=25), Group 3: TiUnite (n=25). Peri-implant crevicular fluid (PICF) was collected and SOD was quantified using an ELISA kit. Statistical analysis was performed using one-way ANOVA, followed by Tukey’s HSD post hoc. Results and discussion: The SOD level was low in group 3 (204.73±1.96 pg/mL), followed by group 1 (216.32±2.40 pg/mL) and group 2 (240.67±7.09 pg/mL). Difference in SOD levels was observed on comparing the groups (p = 0.00). Also, pairwise comparison showed a statistically significant difference among groups (p = 0.00).Conclusions: Superoxide dismutase level in peri-implant crevicular fluid was low around the TiUnite dental implant, compared to SLA and SLActive implants.
