statement of problem: nowadays, evaluation of the development of occlusion in deciduous teeth for creating corrective occlusion in permanent teeth is one of the most important objectives of pediatric dentistry. in other countries, a vast number of researches have been accomplished on the details of occlusion in deciduous teeth. but, unfortunately, there is still no accurate information about th...

Introduction: The objective of this study was to gather information about normal occlusion and arch dimensions in the primary teeth of the children belonging to an Iranian population. Methods: This descriptive cross-sectional study was performed on 68 children from the city of Mashhad in the 3-5 age range. Dental arch dimensions, interrelationships of primary canine and second molars, overbite ...

Objective: To study occlusal features and their relation to caries experience in Hong Kong Chinese preschool children. Methods: Seven kindergarten classes in Hong Kong were selected using a stratified random sampling method, and the 4- and 5-year-old Chinese kindergarten children were invited to join the survey. Two calibrated dentists performed the clinical examinations in the kindergartens. O...

: As a dentist, it is very important to know the occlusal relationship of primary dentition so that any malocclusion in permanent can be predicted at early stages and corrected accordingly by orthodontic treatments. The ideal occlusion spacing acts as mirror for prevalence dentition. aim study was assess relationships between canines molars spacings among group 3-6-year-old children. A total 12...

Advancements in computer science and magnet design have resulted in the recent development of high resolution NMR imaging systems. Using our primate model we evaluated the ability of NMR scanning to detect early changes following middle cerebral artery (MCA) occlusion. Serial NMR scans documented progressive changes secondary to edema and swelling beginning ninety minutes after MCA occlusion. N...

In this article I would present evidence to show that timing of the flow of neural signals within the ventral visual stream is a crucial part of the neural code for categorization of faces. We recorded the activity of 554 inferotemporal neurons from two macaque monkeys performing a fixation task. More than 1000 object images including human and non-primate animal faces were presented up to 10 t...

This paper proposes a shape-based neurobiological approach for action recognition. Our work is motivated by the successful quantitative model for the organization of the shape pathways in primate visual cortex. In our approach the motion-salience region (MSR) is firstly extracted from the sequential silhouettes of an action. Then, the MSR is represented by simulating the static object represent...
