Despite the technical challenges involved when collecting, processing and analyzing gingival crevicular fluid samples, research using gingival crevicular fluid has, and will continue to play, a fundamental role in expanding our understanding of periodontal pathogenesis and healing outcomes following treatment. A review of the literature, however, clearly demonstrates that there is considerable variation in the methods used for collection, processing and analysis of gingival crevicular fluid samples by different research groups around the world. Inconsistent or inadequate reporting impairs interpretation of results, prevents accurate comparison of data between studies and potentially limits the conclusions that can be made from a larger body of evidence. The precise methods used for collection and analysis of gingival crevicular fluid (including calibration studies required before definitive clinical studies) should be reported in detail, either in the methods section of published papers or as an online supplementary file, so that other researchers may reproduce the methodology. Only with clear and transparent reporting will the full impact of future gingival crevicular fluid research be realized. This paper discusses the complexities of gingival crevicular fluid collection and analysis and provides guidance to researchers working in this field.
