SUMMARY:

Osteomyelitis is defined as an inflammatory state of the bone and its etiopathogenesis is multifactorial, including trauma, systemic diseases and odontogenic infections. Therefore, this research is an analysis study of the analysis of retrospective and comparative evaluation studies of the types of osteomyelitis and their evaluations, which consist of clinical-pathological characteristics such as clinical-pathological characteristics in the jaws, diagnosed in the Oral Pathology, Department of Dentistry of the UFRN lesion, in the period from January 1970 to December 2021. The sample consists of 75 cases of acute osteomyelitis, with 9 cases of acute osteomyelitis, 3 of primary chronic osteomyelitis and 63 cases of secondary chronic osteomyelitis. A collection of clinical data was carried out, from which demographic data, drinking and smoking habits, disability resources and treatments used were performed. Radiographic analysis of location considered bone loss, dimension, pat fracture, bone sequencing, reactional, and size. The morphological study evaluated osteoblasts, osteoclasts, bacterial colonies, necrotic bone and granulation tissue. For statistical analysis, the fisher tests and the chi-square test were used. The results found were revealed with the predominant female sex (n=67; 89.3%). The average age was 42,68 years, with variations between 3 and 85 years old, patients self-reported as white were predominant (n=37; 49.3%). As for the types of osteomyelitis, secondary chronic osteomyelitis was predominant (n = 63; 84%), followed by acute osteomyelitis (n = 9, 12%) and primary chronic osteomyelitis (n = 3; 4%). As for the anatomical location, the mandible was predominant with (n=70, 93.3%). As for the causes, odontogenic infection was more prevalent with (n=41; 54.7%). The inflammatory process was present in all cases (n=75; 100%). As for the types of osteomyelitis, secondary chronic osteomyelitis was predominant (n = 63, 84%), followed by acute osteomyelitis (n = 9, 12%) and primary chronic osteomyelitis (n = 3, 4%). As for the anatomical location, the mandible was predominant with (n=70, 93.3%). As for the causes, odontogenic infection was more prevalent with (n=41; 54.7%). The inflammatory process was present in all cases (n=75; 100%). As for neutrophils, they were absent in most cases (n=51; 68%) and discreetly present in (n=18; 24%). In view of the results obtained, we conclude that osteomyelitis is more common in females with a mean age of 42.68 years, with the most common type being secondary chronic osteomyelitis, originating from odontogenic infection and located in the mandible. The association between the type of osteomyelitis and the presence or absence of bacterial colonies showed a statistically significant association. The same did not happen with the other statistical associations carried out in this research.
