Introduction: This study was carried out in three dental clinics in Benghazi to identify and characterize some bacteria in patients with dental caries, abscess and gingivitis and antibiotic resistance patterns to determine the risk to public health. The dental disease specially caries is a significant public health problem affecting a number of children and adult Throughout the globe. Materials and methods: This cross-sectional study was carried out for a period of six months, from October (2020) to April (2021). A total of 100 samples collected from the dental caries patients of various age and sex were processed on different bacterial isolation media like Tryptose Soya Agar, Nutrient Agar, and MacConkey Agar. the colonies were and cultured on Coliform Agar with 5% dehydrated sheep blood, Tadd Hewitt Agar (THA), and LuriaBertani (LB) medium (10). Results: Four different bacterial species were ascertained from the total hundred samples. bacterial species were isolated (Streptococcus mutans 55%, Pseudomonas aeruginosa 15%, Klebsiella oxytoca 10% and E. coli 20%). Different species of bacteria showed various sensitivity patterns to several kinds of antibiotics. Statistical measurement shows no relationship between bacteria and gender and also the age was statistically not significant (P=0.079, P=0.248), respectively. Conclusion and future scope: In this current study Streptococcus mutants was the major cause of dental caries with major percent of infection, as the same time was found no relationship between (age, gender) and bacterial infection which may be due the lack of culture education and attention to health. Furthermore, studies required health education about antibiotics and selling of all kinds of it as over the counter drug should be stopped by implementing medical rules and regulations
