5. APPLICATION
- They are used in Resin based composites (RCB), which are frequently used in Denstry.
- These Resins are cured by LED lights, which are activated by Photo initiators additive.
- Camphorquinone is one of the leading photo initiators used in Dental Resin based composites.
- Camphorquinone contains Selenium content less than 10 PPM therefore it is safe for Dental application.
- The minimum optimum concentration of camphorquinone in BISGMA/TEGDMA flowable composite is 1 % weight of resin matrix, which allows adequate balance among degree of conversion, depth of cure, mechanical properties and color characteristics of these materials. (Refer Hindawi, BioMed Research International, Volume 2018, Article ID 7921247, 10 pages).
- STUDIA UBB PHYSICA, Volume 61, (Lx1), 2, 2016, pp 720 Studied the photophysics of photo initiator Camphorquinone bu using time-dependent Density Functional Theory method, i.e. DFT calculations. Adsorption and emission spectra of photo initiator Camphorquinone had been calculated, the calculated electronic absorption energy at 484 nm was in excellent agreement with available experimental data.
- Biomaterials 24 (2003) 2097-2103 studied the Camphorquinone/amine photo initiator system using blue light emitting diodes. These results suggest that the new LED unit perform better than conventional halogen units with respect to light energy.
