AB  - Objectives: Procalcitonin (PCT) has recently emerged as an important biomarker for an early and accurate diagnosis of bacte­rial infection, hence suggested as biomarker of periodontal disease caused by oral pathogenic microorganisms. Altered DNA meth­ylation of PCT coding gene - calcitonin-related polypeptide a (CALCA) has been shown during systemic inflammation. The aim of this study was to evaluate the influence oflocal and/or systemic inflammation present during periodontitis and diabetes on DNA methylation status of CALCA and its potential use as epigenetic­based biomarker of these chronic inflammatory conditions. 
Methods: The study included 65 individuals divided in three groups: healthy control (n = 17), periodontitis (n = 27) and diabe­tes/periodontitis group (n = 21). Periodontitis was diagnosed us­ing International Workshop for a Classification of Periodontal Diseases and Conditions criteria (1999) while type 2 diabetes as­sessment was performed according to WHO criteria (2013). DNA methylation profile of CALCA promoter in buccal epithelial cells was analyzed by methylation specific polymerase chain reaction (MSP). 
Results: Decrease in DNA methylation of CALCA promoter was observed in periodontitis and even more pronounced in dia­betes/periodontitis compared to control group, although without statistical significance. Correlation analysis revealed statistically significant relationship between the extent of DNA methylation of the CALCA promoter and glycosylated hemoglobin. Even though it is known that life style affects DNA methylation patterns, there was no difference in DNA methylation of CALCA promoter be­tween smokers/non-smokers and normal/overweight individuals. 
Conclusions: Presented results suggest that local periodontal inflammation contributes to the change, but that only systemic inflammation significantly alters the DNA methylation profile of CALCA in buccal cells. Those results imply that DNA methylation status of CALCA reflects systemic inflammation, but additional studies are needed to estimate usefulness of this epigenetic-based biomarker for periodontal disease.
