Techniques for lighting teeth call to-day
for a whole therapeutical battery extending from a simple
surface cleaning to more or less sophisticated treatments,
including mechanical or chemical treatments.
Protocol for chemical treatments is, to-day,
well established and leads to sure and predictable results
as such is the case with some discolorations due to age for
example.
More severe discolorations such as those
following intake of tetracycline or of fluor at high concentration
can be taken care of with chemical treatments which are often
time consuming and necessitate the association of several
techniques.
More severe and pathologic discolorations
due to a genetic factor such as dentinogenesis
or amelogenesis
imperfecta have to be managed with full or partial covering
of teeth by a cosmetic material (composite or porcelain).
Chemical treatments, whether ambulatory or
at the chair, are very performing. Their chemical activation
by light (halogen, plasma, lasers,
etc.) enhances their efficiency by reducing exposure time
and number of appointments.
During this lecture the author will attempt,
on the basis of numerous clinical cases, to show the very
different origins of tooth discoloration and will especially
insist on the modern techniques, mechanical, chemical and
prosthetic.
