A mathematical model for post-irradiation hardening of photoactivated composite resins

The effectiveness of different polymerization protocols for class II composite resin restorations

“…3,12 In case of hardness testing, the norm for an acceptable degree of conversion at a certain depth from the surface is often set by demanding a hardness of 80-90% of the hardness at the top surface. 1,3,14,15 In vitro hardness measurements are often performed on standard disks of composite resin made in Teflon or metal molds. 1,3,5,12,14,[16][17][18] The disadvantage of using only these molds is the possibility of a changed reflection, transmission and absorption of light compared to the clinical situation in which composite resin is also surrounded by natural tooth structure.…”

Evaluation of a New and Advance Curing Light on the Shear Bond Strength of Orthodontic Brackets

“…The air bubbles that arise during mixing or the uneven consistencies in resins that are mixed by hand result in the weakening of the bond strength in the two-paste system. [3][4][5][6] Then ultraviolet light-cured materials were introduced and quickly replaced those products that were self-cured. These ultraviolet light-cured materials have the disadvantages of radiation hazards and limited depth of cure.…”

Effect of Dental Chair Light on Enamel Bonding of Orthodontic Brackets Using Light Cure Based Adhesive System: An In-Vitro Study

“…Number of factors affect the depth of photoactivated cures which include duration, depth and intensity of visible light penetration, filler type and shade, the reflective characteristics of the backing, the mold size, and the optical configuration of the experimental setup (3,4). While using light cured composite adhesive system, a streamlined bonding process is an important consideration, and the choice of light source is critical.…”
