Nanotechnology have potential to bring about significant benefits, such as improved health, better use of natural resources & imroved quality products. Nanomaterials, nanocomposites, nanoporous materials & nanomembranes will play a growing role in materials development for the dental industry. As with all technologies, nanotechnology have potential to bring about significant benefits, such as i...

teeth and T=permanent teeth) has been increasing from 1957 to 2015 years in Iran. The current survey aimed to test the power of health promotion model for predicting the oral health behavior among high-school students.  Materials and Methods: A cross-sectional study was conducted on 482 high school students in Gorgan city, Iran. Multi-cluster sampling was used to recruit the samples. A research...

We study the combinatorics of addition using balanced digits, deriving an analog of Holte’s “amazing matrix” for carries in usual addition. The eigenvalues of this matrix for base b balanced addition of n numbers are found to be 1, 1/b, · · · , 1/b, and formulas are given for its left and right eigenvectors. It is shown that the left eigenvectors can be identified with hyperoctahedral Foulkes c...

Introduction : Periodontitis and dental caries may be synergistically associated, negatively associated, or completely independent.The aim of this study was to evaluate the correlation between these two diseases and investigate the prevalence of dental caries in periodontitis. Methods: This cross- sectional study has been performed in 180 samples in two groups: periodontal and control group ...

Conventional kinesin has long been known to be a molecular motor that transports vesicular cargo, but only recently have we begun to understand how it functions in cells. Regulation of kinesin involves self-inhibition in which a head-to-tail interaction prevents microtubule binding. Although the mechanism of motor activation remains to be clarified, recent progress with respect to cargo binding...
