T ooth-width ratios are used diagnostically to quantify the harmony between the mandibu-lar and maxillary arches. A number of analyses have been developed to compare the tooth-width ratios of malocclusions to standardized norms. 1-4 The Ho-Freer Graphical Analysis of Tooth-Width Discrepancy (GATWD) provides a simple graphic description of tooth-width relationships between the arches, a comprehe...

FP6 IST research project Ubiquitous Sensing and Security in the European Homeland (UbiSeq&Sens) aims at providing a comprehensive architecture for medium and large scale Wireless Sensor Networks (WSN)s, with the full level of security and reliability required to make them trusted and secure for all applications, while considering early-warning and tracking in a Homeland Security/Defense context...

Background and Aim: Tubular penetration of root canal sealers prevents filling material displacement and overgrowth of microorganisms in dentinal tubules. The aim of this study was to compare the tubular penetration of AH26, EasySeal, and SureSeal sealers in single-rooted teeth using scanning electron microscopy (SEM). Materials and Methods: Fifty human single-rooted teeth were included in thi...

Research on 2-dimensional static articulatory modeling has been performed by using the semi-polar system and the guided PCA analysis of lateral X-ray images of vocal tract. The density of the grid lines in the semi-polar system has been increased to have a better descriptive precision. New parameters have been introduced to describe the movements of tongue apex. An extra feature, the tongue roo...
