RE Hassan-Olajokun, AA Folarin, O Olaniran, AN Umo


The study was conducted at the dental clinic of Obafemi Awolowo University Teaching Hospital Complex, Ile-Ife. A total of 100 carious samples were collected from children of varying age and sexes. The bacteria isolated were S. mutans: 45.6%, Lactobacillus spp: 41.2% and S. aureus: 13.2%. Out of the 100 samples, 88(5) had mixed growth of bacteria and the common bacteria combinations were S. mutans and Lactobacillus spp.(43.2%) , S. mutans and.S. aureus (38.6%) and Lactocillus spp and S. aureus (18.2%)The distribution pattern of dental caries in relation to gender showed a higher frequency in females than males with the initiator S. mutans having 565.8% in female and 44.2% in males. The organisms appear to be more prevalent in children of 6-10 years considering the initiator S. mutans being 73.1% while ages 1-5 years were least affected with 5.8%. prevalence. Pefloxacin, Chloramphenicol, Ceftriaxone and Ciprofloxacin are most effective against the caries-inducing organisms with an average susceptibility range of 76.1% to 92.2%.
