Abstract

Objective: To assess whether treatment of advanced periodontal disease affects plasma levels of serum amyloid A (SAA) and phospholipid transfer protein (PLTP) activity. Design: We measured the levels of SAA and PLTP activity in plasma of 66 patients with advanced periodontal disease before and after treatment by full-mouth tooth extraction (FME).Results: At baseline, median SAA levels in our study population were within the normal range (2.7 'g ml'1) but SAA was elevated (>5 'g ml'1) in 18% of periodontitis patients. Three months after FME, SAA levels were significantly reduced (P = 0.04). SAA did not correlate with any of the periodontal disease parameters. PLTP activity was elevated in patients with periodontitis, compared to the PLTP activity reference group (age-matched systemically healthy adults, n = 29; 18 'mol ml'1 h'1vs 13 'mol ml'1 h'1, respectively, P = 0.002). PLTP activity inversely correlated with average periodontal pocket depth (PPD) per tooth (rs = '0.372; P = 0.002). Three months after FME, median PLTP activity did not change significantly. Conclusions: Full-mouth tooth extraction significantly reduces SAA, a marker of inflammation, while it does not affect plasma PLTP activity. However, the inverse correlation between PLTP activity and average PPD suggests that increased PLTP activity may limit periodontal tissue damage.
