ABSTRACT:Objectives: The microbial community of dental caries with many of the facultatively and obligately-anaerobic bacteria is diverse and frequencies, pattern, and distributions of resistant bacteria vary significantly with geographic regions and often reflect the usage patterns of antibiotics. Therefore, the present study aims to determine polymicrobial pathogens causing dental caries and to determine the antibiotic sensitivity pattern of bacterial isolates. Materials and Methods: This cross-sectional study was carried by following Standard protocols of Bergey’s Manual of Systematic Bacteriology to isolate and identify the organism and further followed by antibiotic susceptibility test of bacterial isolates by disc diffusion method. Results: The incidence rate of dental caries was found to be 62.5% among study population. Streptococcus mutans was most predominant to cause dental caries. All bacteria isolates were found to be most sensitive towards ciprofloxacin followed by other tested antibiotics. Conclusion: Female had more dental caries than male in present study. Ciprofloxacin was the most effective drugs against dental pathogens and β-lactam with β-lactam inhibitors were recommended for bacterial resistance.
