purpose : to evaluate the retinal nerve fiber layer (rnfl) and central corneal thickness (cct) in patients with exfoliation syndrome (xfs) methods : in this comparative case series we measures rnfl thickness and cct 30 patients with xfs and 30 age and sex matched healthy subjects who met the inclusion criteria. results : average rnfl in xfs group were significantly thinner than controls (94.36±...

purpose : to compare central corneal thickness (cct), corneal endothelial cell density, and lens capsule thickness in normotensive patients with and without pseudoexfoliation syndrome (pxs) methods : this was a prospective, comparative, descriptive study. normotensive candidates for cataract surgery with (study group) and without (control group) pxs were enrolled in the study. cct and corneal e...

introduction: this study aimed to compare the thickness of the mesiobuccal furcal canal walls of first and second maxillary molars. materials and methods: this study was performed on total of 30 first and second extracted molar teeth (15 each). the mesiobuccal roots of each tooth were separated at the cement-enamel junction (cej) level and embedded in acrylic resin. the embedded roots were cut ...

We show that graph-theoretic thickness and geometric thickness are not asymptotically equivalent: for every t, there exists a graph with thickness three and geometric thickness ≥ t.

purpose : to describe the macular thickness map of iranian adult with normal retinal status as measured by cirrus’ optical coherence tomography (oct) instrument methods : in this cross-sectional study, one eye of subjects with normal ocular examination and retinal status of at least one eye were recruited. the 512×128-scan pattern and scan area of 6×6 mm2 with software version 4 protocol in cir...

In addition to repeated measures models given by Albert, there are a number of other procedures under the heading of random e!ects models. In the same issue the paper by Omar et al. [1] and to some extent that by Frost et al. [2] deal with some of these procedures in detail. There are also numerous journal articles, for example, Goldstein et al. [3], which generalize the Chi and Reinsel paper w...

introdouction: it is important for the clinician to be aware regarding the necessary thickness of materials used as intra-orifice coronal barriers to prevent microleakage. the purpose of this in vitro study was to compare coronal microleakage of three different thicknesses of white and gray angelus mineral trioxide aggregate (wamta, gamta). materials and methods: a total of 66 canals of extract...
