Aim: As to the assessment of occlusal status pertaining to primary canines and molars, the latter is less within reach as it is difficult to guide jaws towards a centric occlusion while maintaining a vintage point in both direct and indirect observation.  This study was originally intended to assess primary canine occlusion as a practical indicator in the evaluation of primary molar occlusion, ...

BACKGROUND AND AIM: Existence of developmental spaces during the primary dentition period is essential for the permanent dentition period and results in regular eruption of permanent teeth. The wide class of different occlusion and dental arch types during the primary dentition period, based on factors such as race, conducted to research the prevalence of these...

we report a rare case of acute right coronary artery stenosis developing in a patient undergoing aortic valve replacement. we present a case report with a brief overview of the literature relating to coronary artery occlusion associated with cardiac valve surgery – the theories and treatments are discussed. a 85 year-old female was admitted under the care of the  cardiothoracic team with signs ...

introduction : laser therapy prevents complications of proliferative diabetic retinopathy (pdr), central retinal vein occlusion (crvo) and branch retinal vein occlusion (brvr), but its effect on visual acuity is controversial. this study evaluated the effect of laser on visual acuity in these patients. materials and methods: this interventional study conducted before–after treatment and evaluat...

In recent years, the increasing number of unmanned aerial vehicles (UAVs) in low-altitude airspace have not only brought convenience to people’s work and life, but also great threats challenges. process UAV detection tracking, there are common problems such as target deformation, occlusion, targets being submerged by complex background clutter. This paper proposes an anti-occlusion tracking alg...

BACKGROUND: One of the most severe categories pediatric patients is those with concomitant dental occlusion. Owing to increase in quality and effectiveness orthodontic care nowadays reduction duration treatment stage problems occlusion, retention period devices used should be analyzed, which aim this study.
 AIM: To analyze occlusion.
 MATERIAL AND METHODS: The study enrolled 26 child...

This paper presents an effective algorithm for occlusion culling using hardware occlusion queries. Number of queries is optimized according to the results of the queries from several preceeding frames. Parts of the scene which are found to be unoccluded in the recent frames, are tested less often thus reducing the number of queries performed per frame. The algorithm is applicable to any kind of...
