B light-curing unit (Guilin Woodpecker, China) at a light intensity of 1100 mW/ cm2 with an irradiated diameter of 10 mm was used to photo-cure composite samples.
Following removal of excess material from the coronal root face, a light-curing unit is applied to the end of the plastic post to transilluminate light along its entire length to polymerize the surrounding composite resin.
1,2) Even though the mechanical and optical properties of the ceramic materials are important, many variables may contribute to the predictability and clinical longevity of all-ceramic restorations, including the adhesive and luting system used, the curing mechanism, the light-curing unit, and the microstructure and thickness of the ceramic.

Specimens were light cured according to the manufacturers' instructions (20 s with Filtek Supreme A2E/A2D/WE and Opallis A2E/ EBleach Low; or 40 s with Opallis A2D) with the light-curing unit corresponding to each group.
1-3) In addition to the presence of photoiniators in their composition, self-curing components are added to ensure an optimal polymerization even when activating light is severely attenuated due to the presence of an indirect restoration interposed between LA and light-curing unit tip.
The physical characteristics of the light-curing unit used in the study are listed in Table 2.
These lights have different characteristics and advantages, but the optimal light-curing unit for the photopolymerization of composites has not yet been determined.
