INTRODUCTION The purpose of this study was to determine the accuracy and reliability of 3-dimensional craniofacial measurements obtained from cone-beam computed tomography (CBCT) scans of a dry human skull. METHODS Seventeen landmarks were identified on the skull. CBCT scans were then obtained, with 2 skull orientations during scanning. Twenty-nine(More)
OBJECTIVES To test the hypothesis that the sagittal position of the anterior teeth has no effect on pharyngeal airway dimension or hyoid bone position and to investigate the influence of orthodontic retraction of the anterior teeth on each section of pharynx and hyoid position. MATERIALS AND METHODS Forty-four Class I bimaxillary protrusion adults,(More)
INTRODUCTION Facial profile disharmonies in the anteroposterior (AP) position of the mandible are among the most frequent reasons that patients seek orthodontic treatment. Various methods are available for assessing profile preferences, and differences between them could affect treatment decisions. The purposes of this study were to compare and contrast 3(More)
INTRODUCTION The aim of this study was to determine whether 2-dimensional (2D) images produced from cone-beam computed tomography (CBCT) images taken with an iCAT scanner (Imaging Sciences International, Hatfield, Pa) can substitute for traditional cephalograms. METHODS Lateral and frontal cephalograms were taken of a radiographic phantom with known(More)
UNLABELLED It is recommended that health-related materials for patients be written at sixth grade level or below. Many websites oriented toward patient education about dental implants are available, but the readability of these sites has not been evaluated. OBJECTIVE To assess readability of patient-oriented online information on dental implants. (More)
OBJECTIVE To determine pain levels, function, and psychological symptoms in relation to predominant sidedness of pain (right or left) and gender in patients being treated for chronic spinal pain. DESIGN Prospective cohort study. PATIENTS Patients with chronic neck or low back pain undergoing a nerve block procedure in a specialty pain medicine clinic.(More)
INTRODUCTION The purposes of this study were to determine (1) profile preferences of black female patients and (2) whether they can recognize their own profile images before and after orthodontic treatment. METHODS Fifteen black orthodontists, 15 white orthodontists, and 15 black female patients were asked to indicate the images they considered most(More)
The objective of this study was to determine differences between Mexican American and Caucasian judges in the acceptability of lip protrusion in computer animations of two male and two female persons of Mexican descent. Thirty Caucasians and 30 Mexican Americans of varying age, sex, education, and level of acculturation responded to facial profile computer(More)
OBJECTIVE To demonstrate the usefulness of a new imaging system for comparing the morphometric bases of children's self-perception of their facial profile with the perceptions of their mothers and treating clinicians. MATERIALS AND METHODS Rather than choosing among a series of static images, a computer imaging program was developed to elicit a range of(More)
