Abstract: The present study was aimed to isolate most prevalent pathogens present in dental implants and to assess their antimicrobial susceptibility profile against antibiotics. The investigation consisted of 75 dental samples. 10 were implants, 17 were natural teeth as abutments for fixed bridges and 48 were with cavities. All microorganisms were identified by biochemical tests. Predominant genera prevalent in rejected implant were Pseudomonas aeruginosa, Enterobacteria and Flavobacterium. Bacillus subtilis, Streptococcus sp and P. aeruginosa were found around the cavities teeth. The susceptibility profile of the isolates to antibiotics was assessed by well diffusion method. B. subtilis was resistant to metrogel, cephalosporin and penicillin. All P. aeruginosa species were multidrug resistant. Thus the present study reveals the current status of antibiotic resistance of dental pathogens.
