title: Apical transportation: two assessment methods.
abstract: Root canal transportation can lead to treatment failure. A large number of methodologies for assessing root canal preparation have been tried in the past. This study compared two methods for apical transportation measurement: digitised images of longitudinal root sections and radiographs. Sixty upper molar mesiobuccal root canals prepared for endodontic treatment were assessed. The results did not demonstrate statistically significant differences between the two imaging methods used to evaluate root canal transportation. The two methods were proven to be equally reliable.
