The goal.Studying the clinical course’s features of acute odontogenic inflammatory processes of the jaws in children, describing species composition of pathogens, determination sensitivity to antibiotics of various groups in acute odontogenic inflammatory processes of the jaws in childhood. Materials and methods.The case histories of 900 patients were analyzed, microbiological research methods were carried out (microscopic examination of clinical samples with Gram staining, culture method, determination of the sensitivity of theisolated pathogen to antimicrobial drugs).Results.The most common odontogenic inflammatory processes of the jaws were observed in children aged 4–5 years. In48,85 % of cases in a milk bite and in 67,92 % of cases in a permanent bite, the cause of the development of an odontogenic inflammatory process was complicated caries of the mandibular molars. 56% of children had a general condition. The leading causative agent of the inflammatory process of the jaws was in 65,6 % of cases hemolytic streptococcus. In other cases, Streptococcus Viridans(6,1 %), pneumococci (4,3 %), candida (3 %), Staphylococcus aureus(2,8 %), Moraxella cataralis(1,2 %), etc. were detected in the mixed microflora of purulent exudate. The drugs of choice for empirical antibiotic therapy for odontogenic inflammatory process caused by beta-hemolytic streptococcus group A are vancomycin (antibiotic sensitivity –99 %), fluoroquinolones (antibiotic sensitivity –98 %), beta-lactams (antibiotic sensitivity –91 %). The highest percentage of resistance of this microflora was noted to macrolides (41 %), and to clindamycin (33 %). The rapid spread of the purulent-inflammatory process in the maxillofacial region in acute odontogenic processes in children, the resistant microflora of the odontogenic purulent focus require a competent approach when providing emergency care.Conclusions.The obtained has great practical importance for the choice of rational antibiotic therapy.
