Title: Biomodulation with flat top hand piece

Prof. Stefano Benedicenti – University of Genoa

Photobiomodulation (PBM) has been used in clinical practice for more than 40 years and its action mechanisms on cellular and molecular levels have been studied for about 30 years.  In clinical applications, photobiomodulation has been used to successfully induce wound and bone healing, pain reduction and anti-inflammatory effects.  Significant effort has been made to clarify parameters of deposited energy density that will effectively promote positive changes in individual cells while avoiding negative effects.  While the bio-stimulatory effect of laser energy is experienced on a cellular level, the energy is applied macroscopically to large volumes of tissue in a non-uniform manner. As energy passes through tissue, part of it is absorbed so each successive depth of cells is irradiated differently. Beers law is usually used to define this relationship. However, this is inadequate since the dominant form of interaction at wavelengths between 600nm and 1400nm is scattering. Thus as energy enters tissue, its density decreases rapidly.

The presentation would provide the current in-vitro and in-vivo researches on a new flattop handpiece for biomodulation and its usefulness in medical and dental applications.
