The PAR Index has been developed to provide a single summary score for all the occlusal anomalies which may be found in malocclusion. provides an estimate of how far case deviates from normal alignment and occlusion. difference scores between pre- post-treatment cases reflects degree improvement and, therefore, success treatment. Excellent reliability was exhibited within examiners (Intraclass Correlation Coefficient, R greater than 0.91). components have weighted reflect current British...

This paper is based on the winning submission for 1998 Chapman prize awarded by British Orthodontic Society an essay a subject promoting interests of orthodontics. The aim investigation to develop single index assessing treatment inputs and outcomes. An international panel 97 orthodontists gave subjective judgements need treatment, complexity, improvement, acceptability diverse sample 240 initial 98 treated study models. occlusal traits in models were scored according defined numerical...
There has been an escalating interest in three-dimensional imaging devices over the last decade. Orthodontists are beginning to appreciate advantages that third dimension gives clinical diagnosis, treatment planning and patient education. This article focuses on cutting edge technology of cone beam CT, which utilizes conventional X-ray computerized volumetric reconstruction reproduce a image. A variety applications range issues associated with this will be discussed.
Structured Abstract Authors – Toma AM, Zhurov A, Playle R, Ong E, Richmond S Background The three‐dimensional (3D) measuring technology is useful to inspect facial shape in three planes of space (X, Y, and Z). Recent work has been directed analyse craniofacial morphology using soft tissue landmarks identify differences among population. reproducibility almost necessary ensure accurate 3D measurements. Objective aim this study assess the laser‐scan imaging technology. Subjects Methods Facial...
Diffusion weighted (DW) MRI facilitates non-invasive quantification of tissue microstructure and, in combination with appropriate signal processing, three-dimensional estimates fibrous orientation. In recent years, attention has shifted from the diffusion tensor model, which assumes a unimodal Gaussian displacement profile to recover fibre orientation (with various well-documented limitations), towards more complex high angular resolution imaging (HARDI) analysis techniques. Spherical...
The idea that symmetry in facial traits is associated with attractiveness because it reliably indicates good physiological health, particularly to potential sexual partners, has generated an extensive literature on the evolution of human mate choice. However, large-scale tests this hypothesis using direct or longitudinal assessments health are lacking. Here, we investigate relationships between fluctuating asymmetry (FA) and detailed individual histories a sample ( n = 4732) derived from...

Design Prospective clinical trial. Setting and Sample Population University Dental Hospital, Wales College of Medicine, Biology Life Health Sciences. Three subjects requiring bi‐maxillary were recruited the study. Experimental Variables Laser‐scanned images obtained under...
As part of an ongoing programme to improve diagnosis and treatment planning relevant implant placement, orthodontic dentomaxillofacial surgery, a study has been made the spatial accuracy density response i-CAT, cone beam CT (CBCT) dental imaging system supplied by Imaging Sciences International Inc.Custom-made phantoms using acrylic sheet water were used for measurements on accuracy, noise. The over period several months clinical machine rather than dedicated research.Measurements precision...
