Introduction: Oral Viridans streptococci are associated with dental caries, infective endocarditis, septicemia and purulent infections of oral and maxillofacial regions. Their emerging resistance to antibiotics in healthy children may represent a potential problem in the management of these infections. Objectives: To evaluate the prevalence and to compare the frequency of resistance between different species of oral Viridans streptococci to 5 antibiotics. Materials and Methods: An Analytical cross sectional study was designed. Supragingival plaque samples were collected with sterile curettes from 51 healthy children selected by simple random sampling. They were inoculated, incubated and identified. 82 representative colonies of 3 species were sub cultured in blood agar plates and antibiotic susceptibility was tested using Disc diffusion method. Zone of inhibition was measured and was analyzed using SPSS 16. Results: Out of the 82 isolates, 39 S.mutans (47%), 21 S.mitis (26%), 22 S.salivarius (27%) were obtained. Penicillin G resistance was more frequent in overall and in each individual species than other antibiotics which was statistically significant. S.mitis showed highest frequency of resistance to penicillin G (76.2%, P = 0.000) and erythromycin (47.6%, P = 0.002) which was statistically significant. All the isolates were uniformly susceptible to vancomycin.
