摘要: Abstract Objective The goal of this study was to compare the tissue-dissolution potential and antibacterial effectiveness a conventional Ca(OH)2/saline paste with equivalent Ca(OH)2/NaOCl Ca(OH)2/chlorhexidine digluconate medications. Study design Tissue specimens were obtained from freshly dissected pig palates. pieces similar form weight incubated in air-tight containers Ca(OH)2 pastes or solutions proper for up 7 days. Antimicrobial testing performed dentin blocks infected Enterococcus faecalis. Medicated, sealed 1 5 days, bacterial growth tested at different depths. Results Up day 4, Ca(OH)2/irrigating solution mixtures dissolved tissue more effectively than paste. After however, no statistically significant differences found between saline hypochlorite mixtures, but medication significantly less effective. Dentin block disinfection quicker thorough Conclusion Ca(OH)2/irrigant under investigation appear advantageous mixture, merit further clinical study.
