About this study
This clinical trial evaluates the role of cytokines in patients needing root canal treatment with diagnosis of necrotic pulp and chronic apical periodontitis
Read the detailed description
This study evaluates whether periradicular exudate concentrations of cytokines differ in patients experiencing pain and mechanical allodynia due to pulpal necrosis with an acute exacerbation of a chronic apical periodontitis, as compared to patients with pulpal necrosis with chronic apical periodontitis, but no pain or mechanical allodynia
