The mechanical behavior of dental enamel has been the subject of many investigations.
Initial studies assumed that it was a more or less homogeneous material with uniform …

Enamel is the hardest biological substance in the human body and is a composite material
consisting of both a mineral and an organic phase. The mineral phase predominates (95–96 …

Recent nanoindentation studies have demonstrated that the hardness and Young's modulus
of human molar enamel decreases by more than 50% on moving from the occlusal surface …

The development of dental biomaterials is now on the rise, with new materials created at a
high rate and in large variety. Yet, considerable effort is needed to improve their physical …

I review the nuclear reactions which are suitable for ion beam analysis of fluorine in
materials and for profiling fluorine in the outer few μm. The 19 F (p, αγ) 16 O and 19 F (p …

Teeth are the most common elements in the human fossil record—largely because they're
the most resilient structures in the body. For the most part, they are made of inorganic …

Teeth have provided insights into many topics including primate diet, paleobiology, and
evolution, due to the fact that they are largely composed of inorganic materials and may …

In 1970, Johansson et al.(1970) demonstrated that the bombardment of a specimen with
protons of a few megaelectron volts (MeV) gives rise to the emission of characteristic x-rays …

The applicability of various ion beam analysis (IBA) techniques for trace elemental and/or
isotopic measurements in biology and medicine is demonstrated. Emphasis is placed on …

The purpose of this study is to determine and compare the fluorine concentration in human
teeth from two different populations, living in the Portuguese quite isolated islands of Açores …
