Summary
Simvastatin (SIM) and diclofenac (DC) solutions demonstrate antimicrobial and residual activity against endodontic biofilms. These findings suggest potential new strategies for infection control in endodontic therapy.
Area of Science:
- Endodontics
- Microbiology
- Pharmacology
Background:
- Endodontic therapy success hinges on effective infection control.
- Endodontic biofilms pose a significant challenge to treatment outcomes.
Purpose of the Study:
- To evaluate the in vitro efficacy of Simvastatin (SIM) and diclofenac (DC) solutions against endodontic biofilms.
- To assess the antimicrobial and residual activity of these agents.
Main Methods:
- Mature multispecies biofilms were cultured on dentin specimens.
- Biofilms were exposed to varying concentrations of SIM (8%, 4%), DC (4%), sodium hypochlorite (2.5%), and saline (0.9%).
- Cell viability was assessed using ATP assay and flow cytometry; residual activity was measured after 3 weeks.
Main Results:
- All tested solutions significantly reduced biofilm compared to the control.
- 2.5% sodium hypochlorite showed the highest reduction, followed closely by 8% and 4% SIM.
- 4% diclofenac exhibited significant residual antimicrobial activity, indicated by a higher percentage of dead cells.
Conclusions:
- Simvastatin (4% and 8%) and diclofenac (4%) solutions possess notable antimicrobial and residual activity against endodontic biofilms.
- These agents show promise as adjuncts in managing endodontic infections.
