Resumen

Most dental pulp diseases and diseases of tissues surrounding the root are somehow related to micro-organisms. Peptidoglycans and lipoteichoic acid are two of the main Gram-positive bacteria components with activities related to sepsis development. When tissues sustain microbial invasion the host responds with both unspecific inflammatory defenses and specific immunological reactions. Surgical and non surgical endodontic treatments are essentially debridement procedures intended to destroy and eliminate the microbial eco-system associated to the pathological process. It is essential for clinicians to understand the intimate relationship existing between micro-organisms and endodontic disease, so as to be able to tailor a rational and effective treatment especially in subjects susceptible to infective endocarditis processes. In the present study research was conducted on TNFα, IL-1 COX-2 expression through the effect of lipoteichoic acid (LTA) of Streptococcus sanguinis by characterizing intra-cellular signals involved in H9c” cardiomyocytes. The cell line was treated with LTA at different concentrations during 30 minutes. When compared to control group, responses to LTA treatment were dependent on dosage. That expression was assessed by means of a One Step RT-PCR (Invitrogen) analysis. It was noted that the aforementioned expression resembled the organisms’s physiological response during an infective endocarditis episode and to exacerbation observed during an endodontic procedure.
