Analysis of Potential Factors Affecting Peri-implant Sulcus Fluid (pisf) Volume

Background and Aim: PISF analysis is receiving more importance among site specific tests based on the understanding that it has the potential to reflect the actual status of periimplant soft and hard tissues. Better understanding of the biodynamics of peri-implant sulcular fluid (PISF) may be an important concern both from a clinical and research aspect. As peri-implant sulcular fluid volume is known to be effected by an array of factors, the aim of the present study was to analyze the potential impact of various peri-implant site-related and dental implant-related factors on PISF volume. Materials and Methods: PISF was obtained from a total of 128 implant sites. These sites were divided into different subgroups based on the presence/severity of peri-implant inflammation, probing depths (PD), implant features (diameter and length), location of implant (maxilla or mandible) and surgical preference (one-stage or two-stage surgery). Differences between these subgroups were statistically analyzed. Results: PISF volume was higher at sites with peri-implant mucositis (0.19 μl) and peri-implantitis (0.21 μl) than clinically healthy sites (0.09 μl). Although peri-implantitis group had the highest volumetric value, the difference between periimplantitis and mucositis groups was not significant. Higher PD values also lead to higher PISF volume. Despite the fact that higher PISF volume was detected at implant sites with one-stage surgery (0.198 μl) compared to two-stage surgery (0.147 μl), in mandible (0.166 μl) compared to maxilla (0.149 μl), in wide implants (0.165 μl) compared to narrow ones (0.141 μl), the difference was not significant (p>0.05). In long and medium implants compared to short ones, higher PISF volume was detected (p<0.05) Conclusion: Findings of the present study suggest inflammatory peri-implant condition is the main factor that have an influence on PISF volume, while some other factors seemed to have less or limited impact. For reliable PISF analysis, all factors with the potential to influence the actual PISF volume are likely to need a particular concern.
