Comparative Evaluation of Microbial Reduction Using Silver Diamine Fluoride, (Neem) and Sodium Hypochlorite as Root Canal Irrigants after Biomechanical Preparation in Uniradicular Canals: An Study.

Background: It is difficult to completely eradicate microorganisms from the infected root canal system. Intracanal irrigants seem necessary for eradication of infected tissues and microorganisms in addition to mechanical debridement. Continuous use of chemical antimicrobial agents leads to serious side effects. Therefore, the need arises for alternative agents to overcome the disadvantages of their chemical counterparts.

Aim: To evaluate and compare the antimicrobial efficacy of three endodontic irrigants against clinically isolated bacteria found in root canals containing necrotic pulp.

Materials And Methods: Preirrigation sample were collected using sterile paper points and sent for microbial count. Chemomechanical preparation was performed, and the root canals were irrigated with 5 mL of test samples. After 3 days, the patient was recalled, and a postirrigation sample was collected and sent for microbial count.

Result Synthesis: Both 3.8% silver diamine fluoride (SDF) and 3% sodium hypochlorite (NaOCl) showed a superior capacity to sterilize the root canals compared to the neem group.

Conclusion: The use of SDF as an endodontic irrigant is feasible as it effectively removes the microbes present in the canal.

Clinical Significance: Silver diamine fluoride has not been shown to be cytotoxic or carcinogenic, unlike NaOCl, suggesting it could be used as a potential endodontic irrigant. However, few studies have evaluated the antimicrobial efficacy of SDF as an endodontic irrigant.
