this paper presents an application of partial differential equations(pdes) for the segmentation of abdominal and thoracic aortic in cta datasets. an important challenge in reliably detecting aortic is the need to overcome problems associated with intensity inhomogeneities. level sets are part of an important class of methods that utilize partial differential equations (pdes) and have been exte...
introduction:there are conflicting reports on the effects of surgical removal of impacted mandibular third molars on the periodontium of the adjacent teeth. the aim of this study was to compare the condition of the periodontium six months after extraction of impacted mandibular third molars with baseline values. methods: fifty patients with mesioangular impacted mandibular third molarsparticipa...
introdouction:tooth eruption is recognized as an important aspect of human growth and development. it can be influenced by a number of factors, and it may reflect the general development of a child’s body. the purpose of this study was to determine the age at which the first primary tooth erupted and its relationship with height, weight and head circumference in 3-15-month children in the city ...
Background and purpose: Assessment of tooth length has an important role in success and failure of dental treatments. As yet periapical radiography has been used for the assessment of tooth length causing high x-ray exposure, long time and patient discomfort. Using panoramic radiography can resolve these problems. The major disadvantage of panoramic radiography is monotonous magnification. The ...
Introduction Regenerating a tooth completely in human oral cavity is not achieved by current studies yet. Here, we have conceived a man-induced method to construct a teeth germ which might be used to regenerate a tooth in vivo. This idea was generated by traits of the development of the compound odontoma, a benign tumour of tooth malformation. This is a kind of developmental tooth malformation,...
Drastic changes and turbulence in macro-economic factors have the greatest impact on banks target market attractiveness in Iran. It is assumed that conventional segmentation models at the corporate level are not efficient for banking system. This study aims to develop a new segmentation model at the industry level for banks of Iran. For this purpose, structures and variables at the industry lev...
introduction: the process of discriminating among benign and malignant hyperplasia begun with subjective methods using light microscopy and is now being continued with computerized morphometrical analysis requiring some features. one of the main features called volume percentage of stroma (vps) is obtained by calculating the percentage of stroma texture. currently, this feature is calculated by...
hypercoagulable states are a group of conditions associated with an enhanced tendency toward blood clotting. although usual clinical manifestations of hypercoagulable states are thrombotic events such as deep venous thrombosis, hematoma can also occurs as a result of hypercoagulability in some patients. several inherited or acquired conditions may lead to hypercoagulable states. some of them in...
abstract the attrition of anterior teeth leads to the loss of efficient anterior guidance, which protects posterior teeth from wear during lateral excursions. this clinical report describes a 48-year-old man with diagonal tooth wear and posterior mandibular tooth loss. the clinical diagnosis was based on a complete oral examination, photos, functional analysis of lateral excursion movements, ge...
