digital radiographs need additional metadata in order to be accurate when being converted to analog media. resolution is a major reason of failures in proper printing or digitizing the images. this letter shortly explains the overlooked pitfalls of digital radiography and photography in dental practice, and briefly instructs the reader how to avoid or rectify common problems associated with res...
مقدمه: ارزیابی بالینی بلندمدّت ایمپلنت های دندانی و ساختمان های در بر گیرنده ی آن ها برای رسیدن به آگاهی و دانش بیشتر نسبت به دلایل شکست و موفقیت این درمان یک ضرورت است. به هر حال به دست آوردن نتایج دقیق و قابل تکرار مشکل است. مطالعه ی حاضر به منظور استفاده از تصاویر رادیوگرافی دیجیتال مستقیم در تکنیک دیجیتال ساب تراکشن و مقایسه ی آن با رادیوگرافی های دیجیتال کانونشنال در ارزیابی ا...
Background and Aims: Diagnosis of vertical root fractures often poses a clinical dilemma. Diagnosis of VRF in intraoral radiographs, except in cases where the beam is perpendicular to the direction of fracture is difficult. Misdiagnosis often leads to wrong decisions about the design of teeth future treatment plan. The aim of this study was to determine the diagnostic accuracy of reverse cont...
introduction: external root resorption is a clinical problem that often cannot be detected clinically. thus, radiography plays a crucial role in its diagnosis. however, optimal radiographic quality with minimal radiation exposure {2.1 [en] verify english word/phrase choice} is an important factor in selecting the appropriate radiographic technique. the aim of this study was the comparison of ac...
Background and Aim: Clinical and radiographic diagnoses of dental root fractures have always been difficult and require high accuracy in dental care and treatment. The aim of this study was to compare the diagnostic accuracy of intraoral digital radiography (PSP) and CBCT in the detection of horizontal and vertical root fractures (HRF and VRF). Materials and Methods: For this experimental stud...

Microarray technology is a new and powerful tool for concurrent monitoring of large number of genes expressions. Each microarray experiment produces hundreds of images. Each digital image requires a large storage space. Hence, real-time processing of these images and transmission of them necessitates efficient and custom-made lossless compression schemes. In this paper, we offer a new archi...
Aesthetic and smile design is one of the most important motivations for going to dentists and one of the most of researchers’ attention. The most important aspect of the remedy is to diagnose, especially when aesthetic is concerned and dentist should interfere the patient actively in the treatment planning. It means dentist must know what is aesthetic in patient points of view. One way to ach...
