Detection of in vitro proximal caries in storage phosphor plate radiographs scanned with different resolutions.
OBJECTIVES To investigate the effect of the scanning resolution of storage phosphor plate (SPP) radiographs on the detection of proximal caries lesions. METHODS 10 dentists evaluated 72 proximal surfaces of premolars with respect to caries from SPP radiographs scanned with theoretical spatial resolutions of: (1) the Digora FMX at 7.8 lp mm(-1); (2) the Digora Optime at both 7.8 lp mm(-1) and ...
متن کاملDetection of cavitated approximal surfaces using cone beam CT and intraoral receptors.
OBJECTIVES The aim of this study was to compare cone beam CT (CBCT) in a small field of view (FOV) with a solid-state sensor and a photostimulable phosphor plate system for detection of cavitated approximal surfaces. METHODS 257 non-filled approximal surfaces from human permanent premolars and molars were recorded by two intraoral digital receptors, a storage phosphor plate (Digora Optime, So...
متن کاملComparison of Cone Beam Computerized Tomography and Phosphor Storage Plate in Detecting Artificial Buccal Recurrent Caries
Introduction Recurrent or secondary caries develops at the margin of restorations and causes restorative failure. We conducted this study to compare the performance of Phosphor Storage Plate (PSP) and Cone Beam Computed Tomography (CBCT) scan in detecting buccal recurrent caries under amalgam and composite resin restorations. Materials and Methods Class V cavities were prepared on the buccal...
متن کاملinvestigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances
در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
A Comparison of intra-oral digital imaging modalities: Charged Couple Device versus Storage Phosphor Plate.
BACKGROUND This in vitro study was conducted to compare the accuracy of two digital image receptors in identifying the location of tip of a fine endodontic file and radiographic apex in mandibular posterior teeth. METHODS Fourteen human cadaver mandibles with retained molars were selected. These molars were prepared for access to the canals and an endodontic file #10 was introduced into the c...
