Utilization of Laboratory Tests of a Gingival Crevicular Sample in an Occupational Periodontal Care System: A Pilot Study

Utilization of Laboratory Tests of a Gingival Crevicular Sample in an Occupational Periodontal Care System: A Pilot Study: Takashi Hanioka, et al. Department of Preventive Dentistry, Osaka University Faculty of Dentistry—Periodontal disease leads to tooth loss in workers during their later life. Workers tend not only to be unaware of the disease but also pay transient attention to their periodontal health. Therefore a variety of information on periodontal health is requested for an occupational health promotion systems, in addition to the conventional screening approaches for periodontal disease. Subgingival plaque and gingival crevicular fluid include biological materials that pose a microbial challenge and affect the host response. The aims of this pilot study were to examine whether the gingival crevicular samples obtained from workers could be tested in bulk at a laboratory, and whether the biological markers in the samples could provide information in addition to a conventional screening approach. A total of 182 periodontal sites were assessed in 96 workers by means of the Community Periodontal Index and 10 laboratory tests. Significant relationships were found between the periodontal variables and the parameters of the laboratory test. Principal component analysis revealed four components of the laboratory tests apart from conventional periodontal variables. Explanations given for the components were serum exudate and bleeding, neutrophil, periodontal pathogen and tissue destruction. These findings indicated that laboratory tests of gingival crevicular samples offer information in addition to that obtained by means of the conventional screening approach.
