Epidemiologic characteristics of dentai caries: reiation of DIVIFT and DMFS to proportion of children with DMF teeth

Community Dentistry and Oral Epidemiology, 1985
Abstract— The relation of the age‐specific mean DMFT and mean DMFS to the age‐specific proportion of children with DMF teeth has been studied using the original data of KNUTSON and data of a recent Finnish material. When studying the relationship between the mean DMFT (x) and the proportion of children with DMF teeth (y), three models of regression ...

What statistical method should be used to evaluate risk factors associated with dmfs index? Evidence from the National Pathfinder Survey of 4‐year‐old Italian children

Community Dentistry and Oral Epidemiology, 2009
Traditional approaches to the analysis count data pose analytical challenges, considering the increasing proportion of zeroes in the distribution. The aim of this paper was to predict the probability of "caries-free" subjects and the dependence of dmfs ...

Dimethylformamide (DMF) hepatotoxicity

Toxicology, 1987
Scattered case reports of accidental exposure and a few epidemiological studies have indicated that the liver is the main target organ following acute and chronic exposure to dimethylformamide (DMF). This has been confirmed in several animal species.

Merged- and Separate-Band Behavior of the C═O Stretching Band in N,N-Dimethylformamide Isotopic Liquid Mixtures: DMF/DMF-d₁, DMF/DMF-d₆, and DMF/DMF-¹³C═O

The Journal of Physical Chemistry B, 2011
A combined experimental and theoretical analysis is carried out on the polarized (isotropic and anisotropic) Raman spectra in the spectral region of the C═O stretching (amide I) band of three isotopic liquid mixtures of N,N-dimethylformamide (normal/d(1), normal/d(6), and normal/(13)C═O).

In-Cylinder Optical Study on Combustion of DMF and DMF Fuel Blends

SAE Technical Paper Series, 2012
<div class="section abstract"><div class="htmlview paragraph">The bio-fuel, 2,5 - dimethylfuran (DMF) is currently regarded as a potential alternative fuel to gasoline due to the development of new production technology. However, little is known about the flame behavior in an optical engine.

The Inhalation Toxicity of Dimethylformamide (DMF)

American Industrial Hygiene Association Journal, 1963
Abstract Animals were exposed 58 times to dimethylformamide for 5.5 hours at 23 ppm followed by 0.5 hour at 426 ppm. No clinical signs of toxicity were observed in rats, mice, rabbits, or guinea pigs. Observed effects led to conclusion that the superimposed, short-term, peak exposure produced a hazard.

Ten-year trends in DMF-S and DMF-T in a northeast German adult population

Journal of Dentistry, 2021
The aim of this study was to assess 10-year trends in coronal caries in adults aged 20-83 years using data from the two-representative population-based Studies of Health in Pomerania (SHIP-0/SHIP-Trend-0).Repeated cross-sectional data from 4,286 SHIP-0 and 3,913 SHIP-Trend-0 participants were analysed.

Skin penetrating abilities and reservoir effects of neat DMF and DMF/water mixtures

Science of The Total Environment, 2009
This study was set out to determine the skin permeabilities of neat N, N-dimethylformamide (DMF, denoted as DMF(100%)) and DMF/water mixtures (including 50% DMF/50% water and 10% DMF/90% water mixtures (v/v), denoted as DMF(50%) and DMF(10%), respectively) and to assess their skin reservoir effects on the systemic absorption. The penetration fluxes for

Peculiarities of the mechanism of electroreduction of cinnamic acid in DMF and DMF-H2O mixture

Russian Journal of Electrochemistry, 2011
The electrochemical behavior of cinnamic acid (CA) on the cathodes with a high hydrogen overpotential (Hg, glassy carbon, and carbositall) in the aprotic solvent (DMF) and in DMF with additions of H2O or Et4NOH is studied by the methods of polarography, preparative electrolysis, cyclic voltammetry (CVA), coulometry, and chronoammetry.
