It is unclear whether certain bacteria initiate the development of inflammatory jaw conditions, or whether these diseases create a milieu for dysbiosis and secondary colonization of indigenous flora. At present, there are no comparative studies on the types of bacteria that colonize different inflammatory jaw conditions. Accordingly, this study aims to identify and compare the types of bacteria isolated in osteomyelitis, osteoradionecrosis, and MRONJ. This is a retrospective cohort study of patients diagnosed with inflammatory jaw conditions. The predictor variables were classification of bacteria as oral flora, categorized herein as resident bacteria, non-resident bacteria, or opportunistic organisms. The outcome variables were a diagnosis of osteomyelitis, osteoradionecrosis, and MRONJ. Covariates were age, sex, penicillin allergy, a diagnosis of diabetes and a history of smoking. Data analysis was performed using ANOVA and chi-squared tests. A total of 105 patients with inflammatory jaw conditions were enrolled. The final sample size was 69 subjects of which 16 were diagnosed with osteomyelitis, 20 with osteoradionecrosis, and 33 with MRONJ. There was no difference in the frequency that resident bacteria were isolated. Non-resident bacteria, which included Staphylococcus and Enterococcus among others, were isolated more frequently at 75% in osteomyelitis compared to 60% in osteoradionecrosis and 48% in MRONJ cases. There is weak evidence of significant difference when comparing osteomyelitis and MRONJ cases (P = .08). Opportunistic organisms, which included Mycobacterium and Candida, were isolated more frequently in osteoradionecrosis at 30% compared to 12.5% in osteomyelitis and 12.12% in MRONJ cases. There is weak evidence of significant difference when comparing osteoradionecrosis and MRONJ cases (P = .1). Non-resident bacteria including Staphylococcus and Enterococcus may be more frequently isolated in patients with osteomyelitis, while opportunistic organisms like Mycobacterium and Candida may be more frequently found in patients diagnosed with osteoradionecrosis.
