INFECÇÕES OROFACIAIS DE ORIGEM ODONTOGÊNICA: ASPECTOS PREDISPONENTES, MICROBIOLÓGICOS, SOCIOCULTURAIS E TERAPÊUTICOS

Abstract

Odontogenic infections are caused by a mixed bacterial microflora that can evolve beyond tooth structures and acquire complexity, compromising the patient's life. Knowledge of the main microbial groups involved helps in diagnosis and therapy. This research aimed to characterize orofacial infections of odontogenic origin found in Emergency Care Units in the region of Leblon-Campo Grande/MS and Sidrolândia/MS. This is a quantitative, cross-sectional and analytical study, based on primary data from patients treated at the Emergency Care Unit over a period of 10 months, who showed signs and symptoms of acute infection of dental origin. The study evaluated the microflora involved in infectious processes, as well as the susceptibility of the main microorganisms involved to commonly used antimicrobials. The analysis provided 105 samples with positive growth, identified by Polymerase Chain Reaction, 91 species and 37 genera. The most common genera were Streptococcus spp., Fusobacterium spp., Actinomyces spp., Prevotella spp. These same pathogens, except the genus Actinomyces, showed substantial resistance against important antibiotics, especially clindamycin. It is advisable to carry out studies in a larger scale, monitoring the genders involved in the infections, as well as the evolution of susceptibility to the drugs used.
