<strong>Effectiveness of ChKM solution compared to triple-antibiotic paste as an intracanal medicament for bacteria that cause a chronic periapical abscess</strong>

Introduction: Chronic periapical abscesses are caused by polymicrobial bacteria, including E. faecalis, S. mutans, sanguinis, and P. gingivalis. These bacteria can be eliminated with chlorophenol camphor menthol (ChKM) solution triple-antibiotic paste (TAP) as an intracanal medicament. This study compared the effectiveness of ChKM to medicament for that cause a chronic abscess. Methods: An experimental laboratory was conducted in-vitro microdilution method optical density measurement using spectrophotometer. The cell inhibition percentage calculated determine MIC value. MBC values were confirmed cultivating Mueller Hinton Agar samples, incubating them at 37°C 24 hours, observing bacterial growth. Bacteria did not grow in medium lower sensitive could effective choice. Results: inhibits faecalis ATCC 29212, mutans 25175, sanguinis 10556, gingivalis 33277 4000, 2000, 2000 µg/mL consecutively. While TAP 6, 0.375, 0.75, 1.5 µg/mL, respectively. Moreover, 32000, 8000, 8000 768, 24, 96 µg/mL. Conclusions: effectively inhibited killed medicament, seen from values. However, is more than because much solution. finding indicated lowest concentration It should highlighted this involving specific microbes; thus, further clinical research needed.
