Gingival and periodontal diseases in their various forms have affected human since the dawn of history. The earliest historical records dealing with medical topics revealed an awareness of periodontal diseases and need for treatment.1 The diagnosis of periodontal diseases which involve the soft and hard tissue destruction should be made systematically and should include both clinical and radiog...

BACKGROUND Methods for determining the root canal length of the primary tooth should yield accurate and reproducible results. In vitro studies show some limitations, which do not allow their findings to be directly transferred to a clinical situation. AIM To compare the accuracy of radiographic tooth length obtained from in vivo digital radiograph with that obtained from ex vivo digital radio...

OBJECTIVES This study sought to assess the diagnostic accuracy of cone beam computed tomography (CBCT) with different voxel sizes and intraoral digital radiography with photostimulable phosphor (PSP) plate for detection of periapical (PA) bone lesions. MATERIALS AND METHODS In this ex vivo diagnostic study, one-millimeter defects were created in the alveolar sockets of 15 bone blocks, each wi...

PURPOSE This study evaluated the diagnostic accuracy of the reverse contrast mode in intraoral digital radiography for the detection of proximal dentinal caries, in comparison with the original digital radiographs. MATERIALS AND METHODS Eighty extracted premolars with no clinically apparent caries were selected, and digital radiographs of them were taken separately in standard conditions. Fou...

AIM The purpose of this laboratory research was to compare the accuracy of digital and conventional bitewing radiographs in the diagnosis of recurrent caries under class II amalgam restorations. METHODS AND MATERIALS This study involved 82 posterior intact teeth in which class II amalgam boxes were prepared. Carious lesions were simulated in half of the proximal boxes in the intersection betw...

background: nasal fracture is a common fracture due to trauma. gold standard method in diagnosis of nasal fracture is clinical examination and radiography is used in legal situation. recently, ultrasound is recommended as a noninvasive and simple method in diagnosis of nasal fracture. this study investigates the role of ultrasound in diagnosis of nasal fracture. methods: 126 cases with suspecte...

In 52 patients we compared the accuracy of standard anteroposterior (AP) radiography, mortise radiography and MRI with arthroscopy of the ankle for the diagnosis of a tear of the tibiofibular syndesmosis. In comparison with arthroscopy, the sensitivity, specificity and accuracy were 44.1%, 100% and 63.5% for standard AP radiography and 58.3%, 100% and 71.2% for mortise radiography. For MRI they...
