BACKGROUND First bite syndrome is the development of pain in the parotid region after the first bite of each meal and can be seen after surgery of the parapharyngeal space. The purpose of this study is to evaluate the efficacy of intraglandular injection of botulinum toxin type A (BTA) in patients with first bite syndrome. METHODS Five patients with first bite syndrome developed after head an...
This report presents a case of a ten-years-old girl, who suffered myocardial ischemia following by “black widow” spider bite. A few minutes after the bite, her parents saw a small, black and shiny lesion in insect bite. The clinical signs began about 3-4 hours after the bite. The venom of the Latrodectus mactans “black widow” is toxic, resulting about 5-6 % fatality rate. The case of a black wi...
Introduction: Different factors such as respiratory disorders , genetics, facial growth pattern , tongue malfunction and malposition are associated with anterior open bite. Skeletal open bite is often appeared by increased posterior dentoalveolar height of maxilla and backward rotation of mandible. Many treatment approaches have been developed for treatment of increased facial height problems. ...
statement of problem: digital subtraction radiography (dsr) needs reproducible alignment between the x-ray source, the object, and the film for obtaining identical projections of the same anatomic region. purpose: the aim of this study was to evaluate the effect of bite registrations (placed on individual bite blocks) on the reproducibility of parallel periapical radiographs, obtained every 2 m...
scorpion bite is a common health problem in many parts of the world, including the iran’s tropics. there are thousands of cases and a number of deaths due to scorpion bite every year in the country. the present study aims to provide further data regarding the details, complications and outcomes of scorpion bite cases referring to razi hospital, ahwaz, from march 2011 to april 2012. a total of 2...
Maximum voluntary bite force is an indicator of the functional state of the masticatory system and the level of maximum bite force results from the combined action of the jaw elevator muscles modified by jaw biomechanics and reflex mechanisms. The measurement of bite force can provide useful data for the evaluation of jaw muscle function and activity. It is also an adjunctive value in assessing...
Bite-force performance is an ecologically important measure of whole-organism performance that shapes dietary breadth and feeding strategies and, in some taxa, determines reproductive success. It also is a metric that is crucial to testing and evaluating biomechanical models. We reviewed nearly 100 published studies of a range of taxa that incorporate direct in vivo measurements of bite force. ...
background: snakebite in iran has been a health concern. however, management of snakebite is not standardized and varies from center to center. this study is aimed at devising an evidence-based comprehensive protocol for snakebite management in iran, to reduce unnecessary variations in practice. materials and methods: a narrative search in electronic databases was performed. fifty peer-reviewed...
Bite force, a measure of performance, can be used to link anatomical form and function. Earlier studies have shown bite force to have a significant influence on dietary constraints and ontogenetic shifts in resource utilization. The bonnethead shark, Sphyrna tiburo, is a durophagous member of the family Sphyrnidae. Its diet in South Florida waters consists almost entirely of blue crabs, which a...
Purpose The aim of this study was to compare the root surface areas of the maxillary permanent teeth in Thai patients exhibiting anterior normal overbite and in those exhibiting anterior open bite, using cone-beam computed tomography (CBCT). Materials and Methods CBCT images of maxillary permanent teeth from 15 patients with anterior normal overbite and 18 patients with anterior open bite wer...
