Abstract
Background. Digital
radiography has widespread use in endodontics. Determining a correct working
length is vital for a proper endodontic therapy. The aim of this study was
to compare the accuracy of conventional and digital radiographic
techniques for root canal working length determination.
Methods.
After determining the real working lengths of 50
permanent maxillary central incisors (gold standard), the conventional (E-
and F-speed films) and digital (CCD, PSP) images were obtained using the
parallel technique. The mean registered working length of each modality
was compared with the other and with the gold
standard using one-way ANOVA at P<0.05.
Results.
No significant difference was found between the
recorded working length values using the conventional and digital
radiographic techniques (P=0.828).
Conclusion.
Within
the limitations of this study, it was concluded that there was no difference
between the measurement accuracy of CCD, PSP and conventional imaging
techniques in root canal working length determination.
