A comparison of the antimicrobial efficacy of three
calcium hydroxide formulations on human dentin infected with Enterococcus
faecalis.

This study compared the antibacterial efficacy of three different
formulations of calcium hydroxide by using human dentin specimens that were
infected with Enterococcus faecalis. After exposure to three forms of
calcium hydroxide (calcium hydroxide mixed with distilled water, calcium
hydroxide mixed with 0.2% chlorhexidine, and calcium hydroxide mixed with
camphorated paramonochlorophenol) for 7 days, dentin powder from the
infected specimens was obtained and assessed for bacterial quantity by
spectrophotometry. It was found that calcium hydroxide mixed with
camphorated paramonochlorophenol killed all of the Enterococcus faecalis
inside the dentinal tubules. This result was better than that obtained with
calcium hydroxide mixed with distilled water or with 0.2% chlorhexidine (p
< 0.05). Calcium hydroxide mixed with distilled water and calcium
hydroxide mixed with 0.2% chlorhexidine were ineffective against these
bacteria.-
- Die Autoren untersuchen 3 unterschiedliche Zubereitungen von Ca(OH)2 auf
mit E. Faecalis infizierte menschliche Dentinzylinder. Die Mischung von
Ca(OH)2 und CHKM tötete alle Keime in den Dentintubuli. Ca(OH)2 vermischt
mit destilliertem Wasser und Ca(OH)2 gemischt mit 0.2%igem CHX waren
unwirksam gegen E. Faecalis.
