Abstract

The standardized radiographic device for digital subtraction radiography (DSR) was developed to detect bone repair of periapical lesions after root canal filling. The radiographic reproducibility of the device was examined over a period of 6 months. The detectability of DSR, and the quantitative accuracy of bone changes were investigated. Results were obtained as follows: the angulation error of this instrument was limited to ±1° in the vertical and horizontal directions over a period of 6 months, which indicated that this instrument was adequate for clinical use in DSR. The accuracy of the quantitative evaluation of bone change was within ±10%.
