OBJECTIVE To assess the effect of Eutectic Mixture of Local Anaesthetics cream and rattle on soothing the vaccination pain on four-month-infants. METHODS The single blind randomised clinical trial was conducted from May 2012 to February 2013 at a clinic under the Gonabad University of Medical Sciences, Iran, and comprised four-month infants who were selected randomly and divided into three gr...

An accurate value for the radiative lifetime of the 2s 2p~(~P) 3s ~P~ level in N II has been obtained using the beam-foil-laser spectroscopy method. The result (T = 0.456 ± 0.020 ns ) is shorter than the beam-foil lifetime values reported previously for the 3s' ~P term. No theoretical value for the lifetime of this term is available at the present time.

OBJECTIVES The aim of this study was to compare the accuracy, reproducibility, efficacy and effectiveness of measurements obtained using digital models with those obtained using plaster models. MATERIALS AND METHODS A total of 20 digital models were produced by the Ortho Three-dimensional Models (O3DM) Laboratory and their software (O3DM version 2) was used to obtain measurements. Identical p...

One thousand five Hong Kong kindergarten children with a mean age of 5.75 +/- 0.46 years were sampled for caries prevalence and related factors. Samples were drawn from a total population of approximately 9,000 5-year-old children. Caries examination was conducted after the teeth were cleaned professionally using a sickle probe (Ash #54) and diagnostic criteria of the World Health Organization....

BACKGROUND AND OBJECTIVE Current studies on the aetiology of developmental defects of enamel (DDE) are subject to recall bias because of the retrospective collection of information. Our objective was to investigate potential risk factors associated with the occurrence of DDE through a prospective cohort study. METHODS Using a random community sample of Hong Kong children born in 1997, we perf...

This study aimed to clarify genetic and environmental contributions to Carabelli trait variation on permanent first molar teeth in a large sample of South Australian twins. Estimates of polychoric correlations were obtained between pairs of monozygous (MZ) and dizygous (DZ) twins for Carabelli data and various gene-environment models fitted by a weighted least-squares approach. The favored mode...

The first significant (leftmost nonzero) digit of seemingly random numbers often appears to conform to a logarithmic distribution, with more 1s than 2s, more 2s than 3s, and so forth, a phenomenon known as Benford's law. When humans try to produce random numbers, they often fail to conform to this distribution. This feature grounds the so-called Benford analysis, aiming at detecting fabricated ...

We have measured hard x-ray photoemission spectra of pure vanadium sesquioxide (V(2)O(3)) across its metal-insulator transition. We show that, in the metallic phase, a clear correlation exists between the shakedown satellites observed in the vanadium 2p and 3p core-level spectra and the coherent peak measured at the Fermi level. Comparing experimental results and dynamical mean-field theory cal...

The study was a cross sectional observational study undertaken to evaluate the frequency of dental caries in mandibular first molar and its antimere in the opposite mandibular quadrant in eight to ten years old children seen at 28 Military Dental Centre. The study involved 100 male and 100 female children of age 6-10 Years. 80(80%) males exhibited evidence of simultaneous presence of dental car...

This study was aimed at documenting the location, shape, and direction of the opening of the mental foramen in dry mandibles of adult black Tanzanian population. A hundred mandibles were available for studying. In 45% the mental foramen was located below the apex of the second premolar, 35% between the second premolar and the first molar, 12% between the first premolar and second premolar and 8...
