The micromotor can be used on patients in various clinical situations, such as when removing composites, removing decay, and finishing/polishing restorative composites.
It operates on the following principle:
the spectrum of ultraviolet light energizes the fluorescent components of certain resins, turning the composite a different colour to the dentin, thus making the professional’s job easier.
Another interesting feature of this light beam is its ability to identify the presence of decay inside the tooth.
APPLICATIONS:
removal of old restorative composites, particularly identifying if the resin has been completely removed during drilling;
decay detection during drilling;
composite finishing/polishing and easier removal of adhesive cements;
post-operative inspection of composite filling margins.
