چکیده

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 root fracture (hrf) and vertical root fracture (vrf). materials and methods: for this experimental study, 60 human mandibular teeth (24 anterior and 36 posterior multi-rooted teeth) were selected. fifteen randomly-selected teeth were fractured horizontally while the next 15 randomly-selected teeth were fractured vertically by use of a hammer and then the pieces were glued back together and were placed in sheep mandibles. radiographic images of all the teeth were taken using intraoral digital radiography (psp) and cbct methods. afterwards, two oral and maxillofacial radiologists assessed the images separately. the data were subjected to diagnostic analytic tests. results: there were significant differences in specificity, sensitivity, positive predictive value and negative predictive value between digital intraoral radiography (psp) and cbct in the detection of hrf and vrf. kappa value for inter-observer and intra-observer agreement in vrf equaled 73.3% for cbct and 54.2% for psp, while in hrf it equaled 63.3% for cbct and 55.4% for psp. conclusion: cbct method has higher specificity and sensitivity in the detection of hrf and vrf compared with intraoral digital radiography.

Comparison of Diagnostic Accuracy of Cone Beam Computed Tomography and Digital Radiography for Detection of Vertical Root Fractures with and without Gutta Percha

  Objective: Diagnosis of vertical root fractures (VRFs) is critical in endodontics which most of the times occurs in endodontically treated teeth with root canal fillings such as gutta percha. Despite Cone Beam Computed Tomography (CBCT) has significantly enhanced image quality compared to digital radiography (DR) which aid the diagnosis, artifacts has remained as a problem in VRF detection . ...

The Effect of Intra-Canal Posts on Diagnostic Accuracy of Cone Beam Computed Tomography and Digital Radiography in Detection of Vertical Root Fractures

Objective: Diagnosis of vertical root fractures (VRFs) is critical in endodontics. Cone Beam Computed Tomography (CBCT)  has significantly enhanced image quality compared to digital radiography (DR) and greatly aids the diagnosis of VRFs but, metal artifacts has remained as a problem in VRF detection.  This study evaluated the effect of intra canal posts on the diagnostic accuracy of CBCT and D...

investigation 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...

Accuracy comparison of CBCT scan and radiography with two different horzental angle in vertical root fracture detection of endodontically treated teeth

Background and Aims: Accurate diagnosis of vertical root fracture (VRF) is a fundamental importance in endodontics. Because of poor prognosis of VRF, digital radiographs with two horizontal angles have limitations in VRF detection. Also, Gutta-percha can produce artifacts that impair CBCT scan accuracy. The aim of this study was to compare accuracy of CBCT and digital radiography system in vert...
