INTRODUCTION The aim of this study was to analyze and characterize root canal morphology of maxillary molars of the Brazilian population using cone-beam computed tomographic (CBCT) imaging. METHODS Patients referred for a CBCT radiographic examination for accurate diagnosis and treatment planning were enrolled in the study. A total of 620 healthy,(More)
INTRODUCTION The aim of this study was to analyze and characterize root canal morphology of mandibular molars of the Brazilian population by using cone-beam computed tomography (CBCT). METHODS Patients who required CBCT radiographic examinations as part of their routine examination, diagnosis, and treatment planning were enrolled in the study. A total of(More)
AIM Line pairs are the unit for measurement of resolution and are related to the spatial quality of the system. Thus, the objective of this study was to evaluate the influence of number of line pairs in digital intra-oral radiography on the detection accuracy of horizontal root fractures. MATERIALS AND METHODS Sixty-four extracted single-root human teeth(More)
The aim of this study was to evaluate the occurrence of pulp stones by cone-beam computed tomography (CBCT) and to correlate their prevalence with patient’s gender, location of tooth (right or left of maxillary or mandibular arch), group of teeth, and restorations. CBCT images of 382 patients randomly selected from the database of the University Oral(More)
A radiographic interpretation is essential to the diagnosis of invasive cervical resorption (ICR) and the difficulty in distinguishing this lesion from internal root resorption has been highlighted in the literature. This paper reports the use of cone beam computed tomography (CBCT) in the diagnosis of ICR. The cases reports describe how CBCT can be used to(More)
OBJECTIVES To determine whether cone beam CT (CBCT) enhancement filters influence the diagnosis of longitudinal root fractures. METHODS 40 extracted human posterior teeth were endodontically prepared, and fractures with no separation of fragments were made in 20 teeth of this sample. The teeth were placed in a dry mandible and scanned using a Classic(More)
PURPOSE To determine the height and volume of the mandibular coronoid process (CP) by cone-beam computed tomography (CBCT) and to identify the presence of any correlations of these measurements with age, gender, facial type, and skeletal class. MATERIALS AND METHODS The sample consisted of 132 patients from a departmental routine patient base. After CBCT,(More)
OBJECTIVES To assess the efficacy of lead foils in reducing the radiation dose received by different anatomical sites of the head and neck during periapical intraoral examinations performed with digital systems. METHODS Images were acquired through four different manners: phosphor plate (PSP; VistaScan(®) system; Dürr Dental GmbH, Bissingen, Germany)(More)
OBJECTIVE Several studies demonstrate variability of root canal morphology of anterior teeth. This in-vivo study was designed to analyze and characterize root canal morphology of maxillary and mandibular anterior teeth using three-dimensional imaging. METHOD AND MATERIALS Patients who required CBCT radiographic examinations as part of their routine(More)
