title: Comparison of Diagnostic Ability of Storage Phosphor Plate in Detecting Proximal Caries with Direct Measurement by Stereomicroscope: A Pilot Study.
abstract: Radiography plays an important role in detection of interproximal caries. The aim of study is to compare diagnostic ability of photo stimulable phosphor (PSP) with direct measurement using stereomicroscope in detecting proximal caries. Hundred proximal surfaces of 50 extracted human posterior teeth were radiographed with dental X-ray unit. The image receptors used was storage phosphor plate Vista scan (size 2), (time of exposure 0.4 s). Radiographs were interpreted and caries lesions were classified on a 4-point scale suggested by Abesi et al. The teeth were sectioned with diamond disc and were examined under a stereomicroscope with 20x magnification. Diagnostic accuracy of digital image is similar to that observed with stereomicroscope. The PSP plate digital X ray system can effectively be employed for detecting proximal caries as compared to direct observation by stereomicro-scope. Further study with more number of observer/evaluator and large sample size is recommended.
