. Elementary and dental radiography / by Howard Riley Raper . Fig. 407. In this bicuspid, one canal filling seems to reach farther than the other. Fig. 408. Same bicuspid, same canal fillings illustrated in Fig. 407. Figure 406 is a radiograph of a case in which the coronoid processwas mistaken for a root of an upper third molar. 15. Without Taking Into Account the Angle at Which theX-rays Were Directed Toward the Tooth and Film, to AssumeThat a Canal Filling Does Not Reach the Apex of a Root Whenit Does. Figure 407 is an experimental case. In Fig. 407 one canal filling 37° APPENDIX reaches- the end of the excised bicuspid root while the other seems to fallshort of the end. Figure 408 is of the same bicuspid, removed from thealveolus, and shows that both canal fillings reach the end of the resectedroot. Figure 409 diagrammatically illustrates why one canal filling has theappearance of not reaching as far as the other in Fig. Fig. 409. Diagram explanatory of Figs. 407 and 408. A, where the shadow of the end of the canal filling in the lingual canal is cast on film. B, where shadow of the end of the canal filling in the buccal canal is cast on film.
