Abstract :

Background: Periapical lesions, are characterized by an immune response to the invading bacteria consequences periapical bone destruction. In root canal treatment failure was found Enterococcus faecalis (E. faecalis) as most species. iNOS found an important role in protection against infection, plays vital roles in fighting pathogens and contributing to disease pathology. Purpose: This study was to observed the role of iNOS in teeth periapical lessions immunopathogenesis caused by E. faecalis. Methods: The randomized post-only control group design used in this study, This study used 24 Wistar rats, were divided into three groups (each group consisted of 8 rats), as negative controls group is a normal teeth, in the positive controls group was made by drilling the upper right first molar to penetrate the dental pulp and was induced with 10μl BHI-b then filled with Glass Ionomer Cement (GIC) and the treatment group, after drilling the teeth, then inoculated with E faecalis ATCC 29212 106 CFU into 10μl BHI-b then filled with GIC to prevent contamination. It takes 21 days to get periapical lesions and rat were sacrificed, and then the expression of iNOS was measured. Results: Statistical analysis using Anova found a significant differenced between control and treatment groups (p<0.05). Conclusion: This study concluded that INOS role in teeth periapical lesions immunopathogenesis caused by Enterococcus faecalis.
