Introduction: Dental caries is the most common chronic condition in children. Recently, there has been a growing tendency to using digital panoramic radiography among clinicians. The present study aimed to determine the accuracy of digital panoramic radiography with and without software enhancement in the diagnosis of proximal dental caries in primary molars. Methods: This study was conducted u...
OBJECTIVE To audit the appropriateness of skill radiography in children attending an accident and emergency (A&E) department with head injuries. METHODS 569 children presenting to a large teaching hospital A&E unit were retrospectively audited. The indications for radiography according to British published guidelines and American published guidelines were compared with the actual requests for...
سابقه و هدف: آماده سازی مکانیکی کانال یکی از مهمترین مراحل درمان ریشه می باشد. ابزارهای چرخشی متنوعی جهت کاهش زمان و بهبود کیفیت آماده سازی در بازار وجود دارد. این مطالعه به منظور مقایسه آپیکال ترانسپورتیشن کانال توسط سه روش آماده سازی دستی، reciprocal و چرخشی (Rase) انجام شد. مواد و روشها: این مطالعه آزمایشگاهی بر روی 45 دندان مولر اول فک پایین کشیده شده انسان انجام شد. تاج از محل CEJ قطع گردی...
Background and Aims: Estimating the canal length is essential for reaching to a proper endodontic treatment. Any error and miscalculation in estimation of the working length, especially in curved canals, can result in complication during and after root canal therapy. The introduction of digital radiography has enabled us to measure curved canal length. The purpose of this study was to evaluat...
OBJECTIVE To compare proximal caries detection using intraoral bitewing, extraoral bitewing and panoramic radiography. METHODS 80 extracted human premolar and molar teeth with and without proximal caries were used. Intraoral radiographs were taken with Kodak Insight film (Eastman Kodak Co., Rochester, NY) using the bitewing technique. Extraoral bitewing and panoramic images were obtained usin...

OBJECTIVE To determine the film-retake rates and causes in digital radiography comparison to conventional X-rays method. STUDY DESIGN Comparative study. PLACE AND DURATION OF STUDY Radiology Department, Aga Khan University Hospital, Karachi, from January 2004 to December 2006. PATIENTS AND METHODS X-rays of different body parts, conducted during the year 2004, with conventional radiograph...
Introduction: Apical seal in blood or dry root canal is a problem in endodontic treatment. Failure of apical seal causes inflammatory reaction and failure root canal treatment. Because of the sealer properties, root canal should be dry for obturation. But hydrophilic sealers can adhere to root canal walls nowadays and this problem is still controversial. This study aimed at determining the apic...
