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 ...

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, 1987Scattered 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.

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, 1963Abstract 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, 2021The 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, 2009This 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

Comparison of oxygen-free graphene sheets obtained in DMF and DMF-aqua media
New Journal of Chemistry, 2021In pure DMF, the graphene layering is mainly limited to 5 layers; in the aqua presence, partial association of the lightest graphene sheets with the highest surface energy occurs.
