Evaluation of the accuracy values of cone-beam CT regarding apical periodontitis: a systematic review and meta-analysis

Abstract

Specialists need to know how accurate and effective each radiographic procedure is, and which ones can provide better images for bone resorption around the apical periodontitis. Therefore, the researcher decided to conduct the present study with the aim of evaluate the accuracy values of cone-beam CT regarding apical periodontitis. The PubMed, Embase, ISI, Scopus, and Medicine have been used to search articles over the last 15years between 2005 and December 2020. Meta-analysis data with 95% confidence interval (CI), Random effect model, and restricted maximum-likelihood methods were calculated. Random effects were used to deal with potential heterogeneity and I2 showed heterogeneity. I2 values above 50% signified moderate-to-high heterogeneity. The meta-analysis has been evaluated with the statistical software Stata/MP v.16 (The fastest version of Stata). One hundred and fifty-eight studies were selected to review the abstracts, six papers met these crucial criteria to do a systematic review and meta-analysis. Sensitivity and specificity of digital periapical radiography was 50% (ES 0.50; 95% CI 0.05, 0.95) and 83% (ES 0.83; 95% CI 0.52, 1.15), respectively. Sensitivity and specificity of cone-beam computed tomographic was 95% (ES 0.95; 95% CI 0.80, 1.00) and 90% (ES 0.90; 95% CI 0.78, 1.03), respectively. In conclusion, CBCT imaging reports values with excellent accuracy vs digital periapical radiography.
