<p>Color stability of Lucirin-photo-activated resin composite after immersion in different staining solutions: a spectrophotometric study</p>

Abstract: Introduction: Exceptional optical properties characterize teeth. As such, an esthetic restorative material should enable the dental professional to imitate the optical properties of natural teeth accurately. IPS Empress Direct was introduced to the market with the claim that it can mimic optically dental tissues with superior clinical performance. Aim: To evaluate the ability of IPS Empress Direct to mimic tooth appearance and color and resist staining. Materials and methods: Three disc specimens were prepared… Show more

“…It can be a stand-alone photoinitiator system or it can be used synergistically with CQ and it does not require co-initiators to accelerate photopolymerization process [ 18 , 31 ]. The use of Lucirin TPO eliminated the amine group and that increase stability of color upon aging [ 42 ] and the color stability is the highest according to resins containing BAPO and CQ/amines [ 38 , 42 ]. It is probably caused by higher molar extinction coefficient, which results in a greater consumption of molecules [ 43 ].…”

“…For clinicians the most important advantage is esthetic aspect [ 48 ]. The TPO-based materials show great color stability [ 6 , 42 , 51 , 53 ] and also can mimic the optical characteristics of teeth such as color, opalescence and translucency [ 27 ].…”

“…Así mismo brinda el resultado en delta el cual nos proporciona exactitud y una medición más completa, cabe resaltar que los estudios realizados en los últimos cinco años han utilizado el espectrofotómetro para evaluar la estabilidad cromática. (15,16,17,18,19,21,23,28,29,35,38) Una de las propiedades ópticas de las resinas compuestas es la estabilidad cromática, la mayoría de los compuestos de las resinas utilizan canforoquinona como sistema iniciador.…”

“…Estos compuestos liberan una pigmentación marrón amarillenta, que al estar inmersa en un determinado tiempo favorece a la penetración del colorante. (35) El fruto Mauritia flexuosa (Aguaje) viene de la planta de Moriche la cual presenta compuestos fenólicos principalmente flavonoides y antocianinas glicosiladas al igual que el Camu Camu. Además, el Aguaje presenta dentro de sus componentes catequina, ácido cafeico, ácido clorogénico, quercetina, naringenina, miricetina, vitexina, scoparina, rutina, cianidin-3-rutinósido, cianidin-3-glucósido, epicatequina y kaempferol.…”
