Objective – Technological improvement is usually followed by comparisons between conventional and new. Those who work with radiographic assessment, such as cephalometric analysis for orthodontic diagnosis, have been living a new challenging and learning phase since the introduction of digital images. It is possible to obtain reproducible and clear images with digital radiography, but radiograph...

Digital Cephalometry is fast becoming the standard of care in contemporary orthodontic diagnosis. Before it can completely take over the traditional methods, it must be demonstrated that it is as accurate as conventional cephalometric radiography. This study was done to compare the accuracy of angular cephalometric measurements on scanned cephalograms with manual tracing as the gold standard. C...

Vertical hydraulic gradient is commonly measured in rivers, lakes, and streams for studies of groundwater-surface water interaction. While a number of methods with subtle differences have been applied, these methods can generally be separated into two categories; measuring surface water elevation and pressure in the subsurface separately or making direct measurements of the head difference with...

This book represents the first single volume in the English language dealing with procedures aimed at the accurate measuring of the female pelvis and the fetal head in utero. Because of the unreliability of the usual external pelvic measurements the obstetrical studies of recent years have tended to neglect this fundamental part of obstetrics. Indeed, until the advent of the Roentgen mensuratio...

OBJECTIVE To determine the predictors affecting treatment outcome after application of the mandibular advancement device (MAD). DESIGN Retrospective analysis. SETTING Tertiary care university hospital. PATIENTS A total of 76 patients (68 men and 8 women) who were treated with the MAD for obstructive sleep apnea (OSA) were included from September 2005 through August 2008. All the subjects ...

OBJECTIVES Habitual open-mouth breathing (OMB) during sleep can cause snoring and obstructive sleep apnea (OSA). This study used a porous oral patch (POP) to treat patients with mild OSA and OMB during sleep. The subjective and objective outcomes were evaluated. STUDY DESIGN Prospective study. SETTING Tertiary referral center. SUBJECTS AND METHODS Patients with ≥5 events hourly but <15 ho...

OBJECTIVES The aim of this study was to verify the concordance of the measurement values when the same cephalometric analysis method was used for two-dimensional (2D) cephalometric radiography and three-dimensional computed tomography (3D CT), and to identify which 3D Frankfort horizontal (FH) plane was the most concordant with FH plane used for cephalometric radiography. MATERIALS AND METHOD...
