Review question

ElementPlanned (methods)Found (results)
PopulationPatients with teeth undergoing non-surgical root canal treatment (primary or retreatment); pre-operative CBCTTeeth treated with root canal therapy; 12 studies (sample sizes 150 to 350); mandibular and maxillary premolars, molars, endodontically treated teeth
InterventionPre-operative CBCT as index test or prognostic predictor (periapical lesions, vertical root fractures, canal complexity)Pre-operative CBCT; voxel size 0.12-0.30 mm
ComparisonReference standard (diagnostic studies); absence of the CBCT-detected finding (prognostic studies)Reference standards varied (clinical findings, 2D radiographs, anatomical validation); absence of CBCT finding
OutcomesDiagnostic accuracy (sensitivity, specificity); root canal treatment success or failure (clinical or radiographic criteria)Pooled sensitivity/specificity for periapical lesions, vertical root fractures, canal morphology (6 diagnostic studies); pooled ORs for failure (6 prognostic studies)
Study designsDiagnostic accuracy: cross-sectional or cohort studies; prognostic: cohort or cross-sectional with follow-up; English, 2013-20246 diagnostic accuracy studies and 6 prognostic studies (cross-sectional, cohort, observational)
TimingPrognostic studies: minimum follow-up of 6 monthsFollow-up 6 months to 5 years; success rates 70 to 95%
