The apparition of bacteria resistant to the antibiotics and their implication in human infections constitute a real problem of public health. The objective of this survey was to determine the resistance level of the bacteria to the antibiotics used in the treatment of the tooth decay. The strain isolation has been performed respectively on BEA (Bile Esculine Agar), Chapman, Cetrimide, EMB (Eosine and to the Bruise of Methylene), MRS (Man Rogosa Sharpe) to the cool blood, MH (Müller Hinton) to cooked blood added polivitex and Colombia to the fresh blood added nalidixic acid and colistine. For their identification, the macroscopic and, microscopic analysis and different tests have been achieved. Enterococcus sp, Staphylococcus aureus, Staphylococcus negative coagulase, Pseudomonas aeruginosa, Klebsiella pneumoniae, Lactobacillus sp, Streptococcus mutans and Streptococcus sp bacterial strains have been isolated with different phenotypes. Of all studied species, Lactobacillus sp and Streptococcus mutans have been confirmed responsible for the tooth decay with 22.2%. This survey showed that the oral dental cavity contains a diversity of bacteria of which most are resistant to the families of used antibiotics.
