Dental calculus: Nano-characterization
2012
Emerging technologies and new nanoscale information have potential to
transform dental practice by improving all aspects of diagnostics and
therapy. Nanocharacterization allows understanding of oral diseases at
molecular and cellular levels which eventually can increase the success of
prevention and treatment. Opto-magnetic spectroscopy (OMS) is a promising new
technique based on light-matter interaction which allows insight into the
quantum state of matter. Since biomolecules and tissues are usually
paramagnetic or diamagnetic materials it is possible to determine the
dynamics of para-and diamagnetism at different teeth structures using that
method. The topography of the surface of a sample can be obtained with a very
high resolution using atomic force microscopy (AFM), which allows observation
of minimal changes up to 10 nm, while magnetic force microscopy (MFM) is used
to record the magnetic field gradient and its distribution over the surface
of a sample. The aim of this study was to determine the possibility of AFM
and MFM for the characterization of dental calculus, and a potential
application of OMS for the detection of subgingival dental calculus.
