In vitro comparison of root-canal measurements with conventional and digital radiology.
2002
Aim The present study compared the efficacy of digital and conventional radiology for root-canal length measurement. Methodology Seventy extracted teeth with pre-served roots were used. Root-canal length measurements were completed with K-Flexofiles (numbers 08, 10 and 15) with conventional and digital radiography using two systems (radiovisiography and photostimulate storage phosphor). All films and sensors were exposed at projections of 0 degrees and 20 degrees to the mesial. The images obtained were evaluated with and without magnification, and analysed using the Cohen's kappa test. The accuracy of the three systems to determine the root-canal length were evaluated by measuring the dista…
Clinical and radiographic diagnosis of approximal and occlusal dental caries in a low risk population
2007
Objective: Determine the agreement between visual detection, conventional radiology and digital radiology methods in the diagnosis of interproximal and occlusal caries in the posterior teeth of a group of patients with low caries prevalence. Materials and Methods: Visual, conventional radiographic and digital radiographic (Digora®, Soredex, Sweden) caries diagnosis was performed in a group of patients (n=30) of both sexes with ages ranging from 15 to 65 years (x = 34 years). Agreement was estimated by the linear weighted kappa index. Results: Kappa = 0.17 was obtained between the visual examination and the conventional radiographic examination and Kappa = 0.16 between the visual examination…
