The basic hypotheses used during these investigations were based on the vibration analysis of the head, which demonstrated that the head is not a solid nondeformable body, but a complex structure including deformable elements. Laboratoire des Systemes Biomecanique (LSBM) has recently proposed three mathematical models: a lumped model, a finite element model(More)
OBJECTIVE There is strong evidence that genetic as well as environmental factors affect the development of periodontitis. Various studies suggest that genetic polymorphisms of the interleukin-1 (IL-1) genes are associated with an increased risk of developing the pathogenesis. The aim of the present study was to investigate the possible relationship between(More)
The authors draw attention to the fact that the possible effects of drugs containing iodine are often neglected during pregnancy. As an example, they report the following observation : "A young woman with benign asthma, treated for 14 years Asthmasedine and Asthmaligne, gave birth, on the 36th week of pregnancy, to a child apparenty dead but who was able to(More)
The effect of epinephrine (Epi) on the microcirculation of the pulp and its neuropharmacological mechanism has been established, as well as the existence of alpha adrenergic receptors in the blood vessels of the pulp. In addition, our results showed that local injections of Epi at doses greater than 10(-8) M produced an extreme drop in intrapulpal pressure(More)
A software using a finite element method is used to study the deformation of a bidimensional model of the human cupular diaphragm and the distribution of angular shearing of the hairs of the sensory cells located on the crista ampularis. This study shows that the hairs on the top of the crista are more sensitive to the pressure difference across the cupula(More)
