Effect of Different Tube Potential Settings on Caries Detection using PSP Plate and Conventional Film

Abstract

Purpose: To compare intraoral Phosphor Stimulable Plate digital system and intraoral film using different tube settings on incipient proximal caries detection. Materials and Methods:Five blocks, with five teeth each, were radiographically examined using phosphor plates and F-speed films. The images were acquired in 07 different tube potentials from 50-80 kV. The films were digitized. Three oral radiologists scored the images for the presence of caries using a 5-point rating scale. The areas under ROC curve were calculated. The influence of tube kilovoltage was verified by ANOVA and pair wise comparisons performed using Tukey test.

Effectiveness of Two Types of Photostimulable Phosphor Plate Plastic Barrier Envelopes for Prevention of Microbiological Contamination

“…In the past, conventional film-based radiography was the most commonly used dental imaging modality. Digital sensors were introduced in the late 1980s [2,3], and have included solid-state sensors namely charge-coupled devices (CCDs), complementary metal oxide semiconductor (CMOS), and photostimulable phosphor (PSP) plates [4].…”
