statement of problem: the goal of a successful endodontic surgery is to establish an adequate seal in apical region. therefore during surgery, root-end resection is essential for an appropriate situation and proper access.purpose: the aim of this study was to determine the most appropriate root-end resection angle to establish adequate apical seal in periapical surgerymaterials and methods: for...

objective(s) the objective of this study was to document and explain bilateral differences in the q angle. materials and methods two hundred limbs of healthy adult indian volunteers were studied. the q angle was measured using a goniometric method with the subjects supine, quadriceps relaxed and lower limbs in neutral rotation. the relative lateral placement of the tibial tuberosity with respec...

purpose : to describe a case of acute angle-closure glaucoma associated with oral topiramate (topamax, aria daroo) therapy case report: two weeks after initiation of oral topiramate therapy for epilepsy, a 35-year-old woman presented with blurred vision and headache. intraocular pressure in both eyes was significantly elevated and her visual acuity was 20/30 ocular uterque (ou). bilateral conju...

purpose: the objective of this study was to identify possible risk factors associated with primary open-angle glaucoma (poag). methods: a case-control study included patients seen at rasoul-akram hospital ophthalmology clinic. cases were consecutive patients with confirmed unilateral or bilateral poag presented during the study period. controls were a random sample of all other patients aged 30...

for assessment and comparison of measuring density methods of festuca ovina, bromus tomentellus and prangos ferulacea, three plants communities are selected. in all of plant community, reference area was defined and samples 7000 (70*100) square meter was selected. whole the area, sampling was accumplished as systematic-random. in each area, 5 transect 100 meter are established. then in areas 70...

introdouction: the purpose of the present study was to determine the possible relationship between gonial angle size and three mandibular morphometric parameters, namely, panoramic mandibular index (pmi), mandibular cortical width (mcw), and antegonial notch depth (ad), in digital panoramic radiographs. materials and methods: pmi, mcw, and ad were calculated in digital panoramic radiographs of ...

this paper discusses the arching effect as the formation of a stable arch in granular materials. for this aim, a developed trapdoor apparatus is designed in order to investigate the arch dimensions in term of the internal friction angle, average size and base angle of materials. observations show that for all tested granular ensembles, width and height of the arch increase with an increase in t...

in this study, we investigated variations of the angle between neck and shaft of femur after amputation of tigh above the knee. in amputated tigh the angle between neck and shaft of the femur is decreased than normal (nearly 90° degrees) (coax vara). the angle of the normal femur usually increases due to weight bearing (coax valga). in the patients that both tighs have been amputated the change...

Background: Scoliosis is the most common type of spinal deformity. A universal and standard method for evaluating scoliosis is Cobb angle measurement, but several studies have shown that there is intra- and inter- observer variation in measuring cobb angle manually.Objective: Develop a computer- assisted system to decrease operator-dependent errors in Cobb angle measurement.Methods: The spinal ...
