Abstract:

Gingival crevicular fluid GCF flow rates were measured with a Periotron 6000 in 60 smokers and 49 nonsmokers. In addition, carbon monoxide CO concentration of expired air was measured, and plaque and gingivitis indices were recorded for all subjects. All subjects completed a medical history and a smokers questionnaire. Smokers also completed the Fagerstrom Tolerance Questionnaire. Differences in GCF flow between smokers and nonsmokers were not statistically different. Smokers had a higher concentration of CO in expired air, more plaque accumulation, and a higher gingivitis score than nonsmokers. The differences in all three parameters were highly significant. GCF was positively correlated with gingivitis scores, but plaque scores showed a stronger correlation in both groups. GCF showed no correlation with either CO levels or number of cigarettes smoked per day. There were strong positive correlations between Fagerstrom scores and daily tobacco consumption, as well as between CO levels and both daily consumption, and lifetime consumption as measured by pack years. Still positive, but slightly weaker correlations were found between GCF flow and plaque accumulation, between CO levels and Fagerstrom scores, between CO levels and years smoked, and between Fagerstrom scores and both pack years and years smoked.
