A Comparative Evaluation of the Effectiveness of Three Different Irrigating Solution on Microorganisms in the Root Canal: An Invivo Study.

Introduction: An infected root canal system either due to caries exposure or trauma cannot be eliminated by the host defense mechanisms alone or in combination with systemic antibiotic therapy. It can be treated through professional endodontic intervention using both chemical and mechanical procedures.

Aim: To suggest triple antibiotic solution containing tetracycline, ornidazole and ciprofloxacin as a new endodontic irrigant that may possess superior antibacterial activity in comparison with chlorhexidine solution.

Clinical and microbiological evaluation of the carious dentin before and after application of Papacarie gel.

Objective: To evaluate clinically and microbiologically the efficacy of Papacarie in the removal of carious dentin in both permanent and primary teeth.

Study Design: Thirty permanent and primary molars with dentinal carious lesions were excavated and subjected to clinical and microbiological assessment before and after application of Papacarie. The gel was further tested for in vitro antimicrobial efficacy against standard cariogenic micro-organisms using agar diffusion assay.
