OBJECTIVES/HYPOTHESIS Open-mouth breathing during sleep may increase the severity of obstructive sleep apnea (OSA) and complicate nasal continuous positive airway pressure (CPAP) therapy in patients with OSA. The aim of this study was to assess the effect of open-mouth breathing on upper airway anatomy using lateral cephalometry and fiberoptic nasopharyngoscopy. STUDY DESIGN This was a cross-...
This longitudinal investigation was undertaken to assess the reliability of the Frankfort Horizontal line (FH) when using either anatomical Porion (Po-a) or machine Porion (Po-m) as reference landmarks. Lateral head films (22 pairs) from subjects at the ages of 11 and 14 years were analysed twice. The results revealed that: (i) the registration error of Po-a was larger than of Po-m; (ii) for Po...
Digital Cephalometry needs to be as accurate as conventional cephalometry in order to be taken as a standard of care in contemporary orthodontics. Objective of this study was to compare the accuracy of linear cephalometric measurements on scanned cephalograms with manual tracing as the gold standard. Cephalometric analysis of specified linear measurements was performed on cephalometric radiogra...
Craniometry is the scientific measurement of skulls, especially in relation to craniology while cephalometry is a branch of anthropometry in which the anatomical dimensions of head and face are measured. Cephalometry continues to be the most versatile technique in the investigation of the craniofacial skeleton because of its validity and practicality [1]. Human body dimensions are affected by e...
background evaluation of the craniofacial bones is the oldest method to measure the facial proportion ratio in orthodontics. objectives the purpose of this study was to evaluate the effect of emboss enhancement on the reliability of landmark identification in digital lateral cephalometric images. materials and methods ten digital lateral cephalograms were selected from the archive of an oral an...
cephalometry and its related analyses have an important role in the evaluation of orthodontic patients. access to an analysis that gives maximum information in the least possible time is an effective way to indicate craniofacial disharmony; therefore, craniofacial templates are very useful tools. the purpose of the present study was to provide orthodontic craniofacial templates for 8-14-year-ol...
Evaluating the maxilla-mandibular vertical dimension is of great importance in constructing successful denture prosthesis, however it is a tedious process which may be misinterpreted leading to false readings. Hence with the aid of cephalometric analysis a cephalogram may present a graphic representation .this study aims to introduce a new mathematical method for of determination the occlusal v...
