Two observers performed measurements twice. Maximum length, depth, and width of the defects were measured with all 3 methods. Manual measurements were accepted as the gold standard. Intraclass correlation coefficients (ICC) were calculated. The mean value of the measurements, the bias, the SD of the differences, and the limits of agreement were estimated.

The estimated bias values for USG and CBCT were 0.18 (0.153-0.21) (P\u2009&amp;lt;\u2009.001) and 0.091 (0.079-0.102) (P\u2009&amp;lt;\u2009.001), respectively.
