Radiographic interpretation of experimentally produced osseous lesions of the human mandible

A new approach for locating the minor apical foramen using an artificial neural network

“…1991), a dried skull was used in the present study to simulate clinical conditions. Likewise, no differences in the results were detected in the presence of soft tissues (gingiva and mucosa) (LeQuire et al. 1977).…”

Periapical health related to the quality of root canal treatment in a Belgian population

“…Furthermore, it should not be forgotten that periapical lesions are not always detected radiographically. Lesions limited to cancellous bone are almost impossible to detect with conventional radiographic techniques (Le Quire et al 1977, Bender 1982, van der Stelt 1985, including panoramic radiographs. Bender (1982) determined that 7.1% MBL (mineral bone loss) was a minimum for detecting a lesion on a radiograph in vitro.…”

Radiographic assessment of simulated root resorption cavities

“…The significance of the trabeeular bone pattern on an observer's ability to visualize resorption cavities has been demonstrated in several studies using dry or wet specimens of human mandibles or maxillas. The general findings in these investigations have been that lesions confined to caneellous bone alone are not visible, while lesions confined to cortical bone ean easily be seen (4, 5,[11][12][13][14][15][16][17][18][19][20][21]. However, a recent experimental study on cadavers has shown that periapical lesions in caneellous bone can be diagnosed if the lesion is bordered by sclerotic bone (22).…”
