The comparative detectability of the artificial periapical defects among Ektaspeed Plus
film, digitized and digora images was evaluated. The artifical detects were made in the
cancellous bone and cancellous-cortical junction with the size of 1.0¡¿0.8§±, 1.4¡¿l.1§±,
and 2.8¡¿2.2§±. The defects in cancellous-cortical junction extended into cortical bone
with the depth of 0. 0.5 and 1.0 §®.
The results were as follows :
1. In junctional defects Ektaspeed Plus film for 2.8¡¿2.2§± defect showed the highest
detectability. But siginificant difference were only found between Ektaspeed Plus films
and digitized images(p<0.05).
2. Almost all defects within cacellous bone were not detected except a flew digitized
and Digora images the size of 2.8¡¿2.2§± Digora images for them showed significant
differences with Ektaspeed Plus films and digitized images(p<0.05).
3. The sansitinity of all imaging modalities were 0.9 or 1.0 in junctional deflects for
the size of 1.4¡¿l.1§±, and 2.8¡¿2.2§±.
For cancellous detects, Digora image showed the highest sensitivity of 0.6 far the size
of 2.8¡¿2.2§±.
4. Siginificant differences for change of exposure time were f3und in most group of
Ektaspeed Plus films and digitized images(p<0.05). But there was no significant
differences in Digora images for cacellous defects.
