Five parameters of gingival crevicular fluid from eight surfaces in periodontal health and disease.
Volume and amounts of myeloperoxidase (MPO), lactoferrin (LF), aryl sulfatase (AS) and lactate dehydrogenase (LDH) were measured in gingival crevicular fluid (GCF) collected from the mesial and distal proximal surfaces of the premolars and first and second molars of 3 subject groups. Group assignment was based on subject mean gingival index (GI) and probing depth (PD) of sampled sites as follows: healthy, GI less than or equal to 0.5, PD less than or equal to 3.0; disease 1, GI greater than or equal to 1.0, PD greater than or equal to 3.0 mm; disease 2, PD greater than or equal to 4.0 mm. Attachment loss (ATL) of most sites in the 3 groups was: healthy, 0-1 mm; disease 1, 1-2 mm; and disease 2, 4-9 mm. GCF volume differed among surfaces and teeth in each of the 3 groups. The greater amount of GCF collected from posterior locations was not related to the GI and PD. Differences with sampling location in amounts of GCF constituents were restricted to MPO and LF. Most of these differences (greater amounts at posterior sites) were associated with more severe disease. Variability in amount and composition of GCF collected from different sites, therefore, should be considered in experiments which include quantitation of GCF parameters. The ratio of MPO in disease group 2 to disease group 1 was greater than similar ratios for GCF volume and LF, AS and LDH. The quantity of MPO was the only measure which differed between the 2 disease groups at all surfaces. MPO thus appears to have the greatest potential, among the measured parameters, to serve as a marker for advanced periodontal disease.
