Title: Tissue-dissolution capacity and dentin-disinfecting potential of calcium hydroxide mixed with irrigating solutions
Abstract: <h2>Abstract</h2><h3>Objective</h3> The goal of this study was to compare the tissue-dissolution potential and antibacterial effectiveness of a conventional Ca(OH)<sub>2</sub>/saline paste with equivalent Ca(OH)<sub>2</sub>/NaOCl and Ca(OH)<sub>2</sub>/chlorhexidine digluconate medications. <h3>Study design</h3> Tissue specimens were obtained from freshly dissected pig palates. Tissue pieces of similar form and weight were incubated in air-tight containers with Ca(OH)<sub>2</sub> pastes or solutions proper for up to 7 days. Antimicrobial testing was performed in dentin blocks infected with <i>Enterococcus faecalis</i>. Medicated, sealed dentin specimens were incubated for 1 and 5 days, and bacterial growth was tested at different dentin depths. <h3>Results</h3> Up to day 4, the Ca(OH)<sub>2</sub>/irrigating solution mixtures dissolved tissue more effectively than the conventional Ca(OH)<sub>2</sub>/saline paste. After 7 days, however, no statistically significant differences were found between the saline and hypochlorite mixtures, but the Ca(OH)<sub>2</sub>/chlorhexidine medication was significantly less effective. Dentin block disinfection was quicker and more thorough with the Ca(OH)<sub>2</sub>/chlorhexidine or the Ca(OH)<sub>2</sub>/NaOCl than with the Ca(OH)<sub>2</sub>/saline paste. <h3>Conclusion</h3> Ca(OH)<sub>2</sub>/irrigant mixtures under investigation appear more advantageous than the conventional Ca(OH)<sub>2</sub>/saline mixture, and merit further investigation in a clinical study.
