Determing the value of delivering light >500nm to dental resins

A new curing light, PinkWave (Apex, Racine, WI) was introduced last year (https://vistaapex.com/pinkwave). This light is unique because it has four distinct wavelength bands that deliver red (625 – 750 nm), infrared (800 – 900 nm), blue, and violet light. The manufacturer also claims that this ‘quad-wave’ light can reduce polymerization shrinkage stress.[13] Initial reports indicate that the value of using this ‘quad-wave’ light to photo-cure current RBCs remains uncertain because the absorbance spectra of four most common photoinitiators used in dental resins; camphorquinone (CQ), 2,4,6-trimethylbenzoyl)-phosphine oxide (BAPO), Ivocerin, and Lucirin TPO will not benefit from receiving light above 500 nm. In view of the fact that dentists are using this light to photo-cure dental fillings in Canada, more research is required to determine the effectiveness of this particular curing light that dentists both in Canada and the rest of the world are using on patients.
This research will:
(1) Measure the spectral radiant power from the PinkWave using a fiber optic spectrometer;
(2) Evaluate the benefit of including light above 500 nm from a curing light using the hardness (VH) and degree of conversion (DC) of flowable and regular-viscosity four different dental resins 24 h after exposure PinkWave
