Enterococcus faecalis (E. faecalis) is a gram-positive bacterium that causes dental calculus in humans. It is also the principal pathogen responsible for dental abscesses, which are partly erupted teeth in which bacteria become trapped between the crown and soft tissues, producing pain and inflammation. This study aimed to isolate and characterize antibiotic-resistant bacteria causing dental infection. Microbiological examination was performed on the samples to detect different kinds of bacteria. The isolates were identified morphologically, biochemically using the automated VITEK® 2 system. Isolates identified were E. faecalis.
Disk diffusion tests were used to determine the antibiotic sensitivity pattern of isolated dental abscess bacteria. Five isolates proved positive for resistance to most of the antibiotics examined.
