Subjects were distributed among three groups. A consisted of teeth that were extracted. B consisted of teeth treated with root-canal treatment followed by apical surgery. C consisted of teeth treated with root-canal treatment only. Pre-treatment PR, ultrasound and CBCT images were obtained for Groups A, B and C and 6\u2009month post-treatment PR and ultrasound images were obtained for Groups B and C. In addition, histopathological analysis was performed on lesions in Groups A and B. Lesions were classified as either cystic lesions or granulomas. Width, height, depth, surface area and volume of lesions were measured using the built-in softwares of the appropriate imaging modalities. Measurements were compared by Wilcoxon and paired sample t tests. Ultrasound and histopathological findings were compared with \u03ba and Mc Nemar. Statistical significance was set at p &lt; 0.05.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results:<\/jats:title><jats:p>\u03ba coefficient (0.667; p = 0.002) suggested good agreement between ultrasound and histopathology. No statistically significant differences were found among periapical radiography, CBCT and ultrasound in the pre-treatment measurements of lesion width ( p = 0.308) or between CBCT and periapical radiography in the pre-treatment measurements of lesion height ( p = 0.863). In all cases, mean measurement values for all variables were lower for ultrasound than for CBCT.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion:<\/jats:title><jats:p>Ultrasound provided useful
