Abstract

Background and Objective: Recently, most digital imaging systems provide the option of image post-processing with different techniques. Thus, the aim of present study was to compare the measurement of distance from CEJ to alveolar crest on original & inverted digital radiograph.
Materials and Methods: In this experimental study, 29 extracted anterior and posterior teeth on Ahvaz dental clinics were gathered and were placed on 10 ovine mandibles. Distance between CEJ to alveolar crest were measured by caliper. Digital radiograph (parallel technique) were exposed on Digora Optime system. Fifty eight points of proximal surfaces for measuring the CEJ to alveolar crest were marked up. The unfiltered and filtered (inverted filter) images were evaluated by two observers. Data was statistically analyzed using SPSS software and repeated measurement test.
Results: Mean for registered data for gold standard (measured by caliper) was 5.5501 and for registered data for first observer on filtered and unfiltered images were 5.0025 and 5.1379 respectively. This means for the same parameters by a second observer were calculated as 5.1483 and 5.0103 respectively. There was no significant difference between original radiograph and the filtered radiograph.
Conclusion: According to the results of the present study there is no significant difference in digital radiograph comparing with and without inverted filter to the gold standard. Thus, there is no priority on using any of the original and inverted digital radiography.
