Peri-implant Crevicular Fluid Volume in Dental Implant Recall Patients at King Saud University

It is generally accepted that peri-implantitis is caused by a bacterial challenge to the implantbearing soft and hard tissues. A few studies have focused on the investigation of peri-implant crevicular fluid (PICF) flow rate and their relationship with the peri-implant condition. Hence, the aim of the present study was to assess if PICF flow rate can be further studied as a possible objective diagnostic aid in dental implants. 63 implant fixtures from 30 systemically healthy subjects were divided into 2 groups, 28 implants with probing depth <3mm (GROUP I) and 35 implants with probing depth >3mm (GROUP II). Plaque Index and probing depth were evaluated for each implant. The volume of collected peri-implant crevicular fluid was measured with Periotronâ 6000. Implants with deep probing depth (>3mm) had significantly higher scores of plaque indexes and higher mean of PICF volume (1.91 ±1.01 and 0.314 ±0.097 μ/L, respectively) (P < .01). The present results suggest that PICF analysis could be a useful quantitative parameter for peri-implant gingival changes.
