“…After that, the full texts of the reserved 31 citations were obtained and evaluated per the inclusion criteria. Finally, 15 studies were included in the systematic review [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31] ( Figure 1). Among the enrolled studies, nine studies reported the diagnos- tic efficacy of CBCT with a sample size of 1097 suspected ERR sites, and 11 reported information of PR with a sample size of 1072 sites (five studies focused on both modalities).…”

Objective: To compare the diagnostic accuracy of cone-beam computed tomography (CBCT) and periapical radiographs (PR) for the detection of external root resorption (ERR). Material and Methods: An electronic search in databases, including the Cochrane Central Register of Controlled Trials, PubMed, Embase, the China National Knowledge Infrastructure, and System for Information on Grey Literature in Europe (SIGLE), was performed until August 2016. A manual search of relevant journals and reference lists of enrolled studies was conducted. The studies investigating the diagnostic accuracy of CBCT or PR for ERR, with simulated ERR as the reference test, were considered eligible. The diagnostic accuracy of CBCT and PR was statistically pooled using a bivariate model. Meta-regression and subgroup analysis were performed to explore the sources of heterogeneity. Sensitivity analysis was used to test the stability of the overall results in the meta-analysis. Results: A total of 15 studies were included in this systematic review. The pooled results showed that CBCT had significantly higher sensitivity (0.89; 95% confidence interval [CI]: 0.77-0.96) and area under curve (0.96; 95% CI: 0.77-0.96) than PR (sensitivity: 0.68; 95% CI: 0.56-0.78; area under curve: 0.88; 95% CI: 0.85-0.90). No difference in sensitivity, specificity, and area under the curve between conventional and digital PR was observed. Conclusions: Currently available evidence suggests that CBCT could be reliable to detect the presence of ERR in clinical practice and has a higher diagnostic efficacy than PR.

“…2,3,4,5,6,16,17,18 However, the margins of the lesions artificially produced with drills in these studies are sharper than those of natural lesions, whose margins tend to be irregular. In the present study, simulated ERR was induced chemically because this procedure affords ill-defined margins that are similar to those with ERR of biological origin and clinical condition.…”

The aim of this study was to determine the efficacy of pixel value analysis using images generated by the Digora™ and Visualix™ systems for the early detection of external root resorption (ERR). Thirty extracted human lower incisors were radiographed using the Digora and Visualix systems; then, ERR was induced by immersing the teeth in 6 mol L-1 of hydrochloric acid for different periods of time (10, 30 and 60 minutes). ERR was confirmed by calcium quantification with an atomic absorption spectrophotometer. One digital image was acquired per time period at 70 kVp, 7 mA, 2.2 mm filtration, focus-film distance of 30 cm, and with exposure times of 0.09 s in the Digora system and 0.05 s in Visualix system. The region of interest was defined using ImageJ software. Statistical analysis was performed using ANOVA and Pearson's correlation (p < 0.05). There was no statistically significant difference between the time for ERR induction and the pixel values with either system. A positive correlation between the time of ERR induction and the calcium concentration was observed (r = 0.8892; p < 0.001). In conclusion, independent of the site of ERR induction and the digital system, pixel value analysis was not effective for ERR detection.

“…Poorly-standardized radiographs may result in a misinterpretation of disease onset or progression. This is particularly salient in the assessment of ERR, which can commence and progress rapidly (3). Even when customized bite blocks attached to the paralleling device are used to take serial radiographs, the images will never be identical (21).…”

“…Scans tended to be taken using the CBCT hardware's manufacturer's settings as was the case in the radiation dose study mentioned previously (27). Ex vivo evidence now exists to suggest that by altering the degree of rotation of the X-ray source and detector from 360° to 180° and therefore away from the manufacturer's settings, the effective dose to the patient is potentially halved without a reduction in diagnostic yield (3,29). Of further encouragement to the application of CBCT in Endodontics is the fact that these studies were examining the diagnostic accuracy of CBCT in the detection of the most common endodontic diseases, namely external root resorption (3) and apical periodontitis (29).…”

Cone beam computed tomography (CBCT) is a contemporary, radiological imaging system designed specifically for use on the maxillofacial skeleton. The system overcomes many of the limitations of conventional radiography by producing undistorted, three-dimensional images of the area under examination. These properties make this form of imaging particularly suitable for use in endodontics. The clinician can obtain an enhanced appreciation of the anatomy being assessed, leading to an improvement in the detection of endodontic disease and resulting in more effective treatment planning. In addition, CBCT operates with a significantly lower effective radiation dose when compared with conventional computed tomography (CT). The purpose of this paper is to review the current literature relating to the limitations and potential applications of CBCT in endodontic practice.
