Effect of Thyme Water Extract on Commonly Found Oral and Root Canal Bacteria (A Comparative Study)

Abstract


Background and objectives: Bacteria and their products play an essential role in the pathogenesis of pulpo-periapical disease. The purpose of this study was to compare the anti-microbial activity of thyme water extract on selected bacterial isolates and culti- vated root canal swabs in comparison with different concentrations of sodium hypochlorite (NaOCl).

Materials and Methods: Clinical isolates of Staphylococcus aureus, Moraxella catarrhalis, and Klebsiella pneumoniae were selected. Microbiological samples from infected root canals were taken from forty five male and female patients in age group of 15-45 years old during the first visit of root canal therapy. Antibacterial assay were done by agar well diffusion method and microdilution assay.

Results: The best antimicrobial activity for thyme extract was noticed at Moraxella catarrhalis and failed to show any significant effect on Klebsiella pneumoniae. The results revealed that 2% sodium hypochlorite are more effective than thyme water extract, on evaluated bacterial isolates and swabs.

Conclusion: From bacteriological point of view, it could be demonstrated that water extracts of thyme (infusion method), may be useful for root canal irrigation with their antibacterial effect.
