Exclusion criteria

Exclusion criteria: Previously initiated endodontic treatment Presence of systemic diseases Patients who had received NSAIDs or antibiotic treatment within the last three months before the study.

Design outcomes

Primary

MeasureTime frame
1.Correlation Coefficient between Delta R values of QLF and CFU counts obtained from culture-based analysis in root canal exudates before and after biomechanical preparation in patients diagnosed with pulp necrosis and apical periodontitis/apical abscess. 2.Correlation coefficient between Delta R values of QLF and microbial counts obtained using real time PCR in root canal exudates before and after biomechanical preparation in patients diagnosed with pulp necrosis and apical periodontitis/apical abscess.Timepoint: After access opening and after biomechanical preparation on the same day

Secondary

MeasureTime frame
Quantitative assessment of changes in microbial count in root canal exudate assessed using CFU count and real time PCR before and after biomechanical preparation.Timepoint: After access opening and after biomechanical preparation on the same day
