Introduction: The objective was to evaluate the efficacy of biochemical markers (WBC, CRP and fibrinogen) and the course of odontogenic space infections in 50 patients.
Material and methods: Blood samples were taken preoperatively and postoperatively at day 0, day 4, day 8 and day 12 for measuring the levels of all three biomarkers. The trends of the biomarkers were observed and compared with assessment parameters such as dental etiology, number of teeth involved, number of spaces involved, mouth opening and pain. Active pus discharge, dysphagia, hoarseness and swelling were assessed and scored accordingly.
Results: The data were subjected to paired 't' test, McNemar's and Pearson's bivariate correlation as appropriate. Statistical analysis found strong correlation between laboratory values of markers and parameters used to measure severity of infection. All three biomarkers (WBC, CRP and fibrinogen) are significant markers for hospital stay (p < 0.01). Prospective analysis indicates that only one biomarker cannot be used to rule out specific diagnosis.
Conclusion: The combination of three biochemical markers assessed in the present study (WBC, CRP and fibrinogen) should be used as prognostic factor in assessment, clinical severity and efficacy of treatment regime for patients as these can reliably predict the clinical course of odontogenic infection.
