Contra-indications
Amalgam fillings must be mechani‐
cally removed before laser therapy.
Gold fillings cannot be ablated with
the laser because gold reflects the
IR radiation very well, and must the‐
refore be mechanically removed be‐
fore laser therapy.
Crowns are to be mechanically re‐
moved before laser therapy.
Metals should not be radiated since
they may heat up the surrounding
tissue due to their high thermal con‐
ductivity.
Metal chips ejected during ablation
may injure peripheral tissue and da‐
mage the laser emission window.
