A visible-light activating unit with experimental light-conductors — photopolymerization in bis-GMA unfilled resins for dental application
On irradiation, for a visible-light activating unit with an attached light-conductor, a peak in the wavelength range 460 to 500 nm was seen every time. A smaller area of plastic fibres occupying the light-cond...

Curing performance of visible-light-cured dental resins due to a selectively-filtered visible-light unit
The spectral distributions of a visible-light curing unit with selectively limited-filters were measured. The results showed that the activation energy for polymerization in an unfilled resin with dimethyl-p-tolu...
