Light devices are used in the
polymerisation of composite resins. Different light devices have been produced
and developed from past to present. After the first UV light sources,
Quartz-Tungten-Halogen light sources, Plasma Arc light sources, Argon lasers
and Led light sources have been used. The properties of all light devices
should be fully known and the selection should be made accordingly. Although
cost is important in the selection of light devices, factors such as residual
monomer formation, polymerisation rate and power of the light source should not
be forgotten. Despite the advances in light devices, polymerisation shrinkage
and residual monomer formation are still a major problem in composite resin
applications. The power of the light device should be checked regularly, and
cleaning and maintenance should be carried out in accordance with the
instructions. The clinician should be familiar with the characteristics of the
light device to be used. The wavelength range in which the light device is effective
should be well known. The spectrum between the restorative material used and
the light device must be compatible. Protective goggles should be used during
the application, the light should be applied at a right angle from the closest
point possible to the restoration, soft-start polymerisation mode should be
preferred, and extra care should be taken in terms of polymerisation in
cavities deeper than 2 millimetres. The aim of this review is to provide
information about the features of light devices, their working principles, how
to use them more effectively and what to pay attention to.
