title: The effect of smoking on myeloid-related protein-8 and myeloid-related protein-14.
abstract: The aim of this study was to determine the myeloid-related protein-8 and myeloid-related protein-14 levels in the gingival crevicular fluid of smoker patients with generalized aggressive periodontitis (SAgP), smoker patients with chronic periodontitis (SCP), smoker patients with gingivitis (SG-smoker control), non-smoker patients with generalized aggressive periodontitis (AgP), non-smoker patients with chronic periodontitis (CP), and non-smoker patients with gingivitis (G-non-smoker control). The periodontal statuses of the patients were determined by periodontal clinical measurements and radiographical evaluations. The levels of myeloid-related protein-8 and myeloid-related protein-14 in the gingival crevicular fluid were assessed using enzyme-linked immuno sorbent assay. The myeloid-related protein-8 and myeloid-related protein-14 levels in the gingival crevicular fluid of patients with generalized aggressive periodontitis (non-smoker and smoker) were found to be statistically higher than patients with chronic periodontitis (non-smoker and smoker) and patients with gingivitis (non-smoker and smoker). Myeloid-related protein-8 and myeloid-related protein-14 levels of non-smokers were significantly higher than smokers in all types of periodontitis and gingivitis. The decreased myeloid-related protein-8 and myeloid-related protein-14 level could have prevented the haemostasis of calcium which plays a significant role in the migration of neutrophiles. Smoking affects myeloid-related protein-8 and myeloid-related protein-14 levels and may inhibit the antimicrobial efficiency against microorganisms. Due to these reasons smoker generalized aggressive periodontitis patients need to be treated in detail and their maintenance durations should be shortened.
