Comparing the Accuracy of Cone Beam Computed Tomography,Digital Intraoral Radiography and Conventional Intraoral Radiography in the Measurement of Periodontal Bone Defects
Background and Aim: Cone beam computed tomography (CBCT) produces high-quality data in periodontal diagnosis and treatment planning. The aim of this study was to compare the accuracy of CBCT with intraoral digital and conventional radiography in the measurement of periodontal bone defects. Methods and Materials: In this diagnostic research, two hundred and eighteen artificial osseous d...
متن کاملComparison of technique errors of intraoral radiographs taken on film v photostimulable phosphor (PSP) plates.
OBJECTIVE The objective of this study was to compare the technical errors of intraoral radiographs exposed on film v photostimulable phosphor (PSP) plates. METHODS The intraoral radiographic images exposed on phantoms from preclinical practical exams of dental and dental hygiene students were used. Each exam consisted of 10 designated periapical and bitewing views. A total of 107 film sets an...

In vitro Evaluation of the Relationship between Gray Scales in Digital Intraoral Radiographs and Hounsfield Units in CT Scans
Background: Jaw bone quality plays an essential role in treatment planning and prognosis of dental implants. Regarding several available methods for bone density measurements, they are not routinely used before implant surgery due to hard accessibility.Objective: An in vitro investigation of correlation between average gray scale in direct digital radiographs and Hounsfield units in CT-Scan pro...
متن کاملLaser-guided intraoral radiography: A future focus
the past few decades, rapid changes have taken place in the fields of science and technology. Simultaneously , great progress has been made in research work on laser applications. Today, laser use ranges from simple applications such as recording prices of groceries to complex applications such as measuring distance to the moon and laser-guided warfare. 1 In the field of dentistry, the research...
