In dieser Studie wird die Wirksamkeit von NaOCL, Ca(OH)2 und Metronidazol auf anaerobe Keime untersucht, die bei der Ausbildung periapikaler Läsionen von bedeutung sind.. Interessant ist, dass festgestellt wird, dass sowohl lediglich 0,05 %iges NaOCl als auch Ca(OH)2 eine im Vergleich zu ihrem antimikrobiellen Effekt ausgesprochen destruktive Wirkung auf Zellkulturen aufwiesen.

Cytotoxicity versus antibacterial activity of some antiseptics in vitro.

Through the development of new techniques for bacterial growth and isolation, obligate anaerobes have been shown to be more prevalent than previously thought in the pathogenesis of periapical and pulpal diseases. A follow-up study was conducted to examine the germicidal effect of 0.05% NaOCl, 10 mg/ml metronidazole and supernatant of Ca (OH)2 (0.025 ml) on four anaerobic microorganisms commonly found in root canals, and to compare the toxicity of these substances on cell cultures. In vitro testing revealed that 0.05% NaOCl and Ca (OH)2 were both equally effective on these anaerobes. Also, metronidazole was found to be germicidally effective against Bacteroides melaninogenicus, Bacteroides oralis and Peptostreptococcus anaerobius, but ineffective against Veillonella alcalescens. Furthermore, it was found that NaOCl and Ca (OH)2 had a very destructive effect on cell cultures compared with their antimicrobial effect, whereas metronidazole was less toxic among the agents tested.
