APPARATUS AND METHOD FOR POLYMERISING DENTAL PHOTOPOLYMERISABLE COMPOSITIONS

摘要

There is disclosed a method for initiating the polymerisation of a photopolymerisable dental composition comprising a photoinitiator capable of initiating the polymerisation when irradiated with light having a wavelength between a lower wavelength and an upper wavelength, which method comprises the step of irradiating the composition with light emitted from a light-emitting diode source having an emission wavelength maximum between the lower wavelength and the upper wavelength. There is also disclosed an apparatus for use in the disclosed method, the apparatus comprising a light-emitting diode source (240), a light conduit (220) having a proximal end and a distal end, and condenser means (230) operatively associated with the source and the light conduit for directing light emitted by the source onto the proximal end (221) of the light conduit.
