A Comparison of Three Different Radiographic Techniques to Evaluate Their Reproducibility Concerning Periapical Structures ? An Experimental Pilot Study

The assessment of periapical structures, inflammation and healing process state many questions concerning diagnostic, characteristics of healing and bone repair in apical stricture. The reproducibility of different x-ray techniques is very important from clinical point of view. Contemporary endodontic treatment requires precise and reliable measurement of periapical lesion and their suspectable healing. Intra-oral bisecting angle technique is no longer a method of choice. The purpose of this study is to compare three different techniques intra-oral bisecting angle, intra-oral parallel and intra-oral parallel with bite registration. Bite registration is of great importance for taking reproducible periapical x- rays in studying the dynamic processes in apical periodontal zone.
