Abstract

Purpose: inflammatory markers involved in the etiopathogenesis of periodontal diseases are also found muscle injury. The aim of the present study was to evaluate the impact of periodontal inflammation on changes of serum levels of a marker of muscle injury (creatine kinase – CK) in young soccer players during regular training. Methods: this observational longitudinal study included 15 male players (18±0.93 years of age). A calibrated examiner performed a full-mouth periodontal examination in six sites per tooth. Thereafter, blood samples for CK measurements (U/L) were taken at baseline, immediately and 20 hours after training. Results: players presented poor oral hygiene (69.2% of sites with visible plaque). Bleeding on probing (BOP) scored 42.7% and probing depth (PD) averaged 2.3mm. CK levels changed significantly from 342.4 to 473.7 and 364.4 during the three time-points. A significant correlation was observed between PD and change in CK from the immediate measurement to 20h (r =-0.57). Significant correlations were observed between BOP and changes in CK from immediate measurement to 20h (r=-0.51) and from baseline to 20h (r=-0.52). Conclusion: pocket depth and bleeding on probing were associated with changes in CK during training.
