Efecto de bebidas pigmentantes en la estabilidad del color de resinas compuestas. Estudio IN VITRO.

Abstract

INTRODUCTION: Composite resins are biomaterials for general use in dentistry that seek to give an aesthetic result to the patient and allow the preservation of healthy dental tissue. OBJECTIVE: To establish how pigmenting drinks influence the color stability of nanohybrid composite resins. MATERIALS AND METHODS: Composite resin discs specifically with a nanohybrid composition were collected from the different commercial companies: Tetric Ceram, Brillant, Llis, Filtek z250, body tone A1, which were subjected to artificial aging in a thermocylator at 10,000 cycles and to the exposure of wine and coffee pigmenting beverages, to compare the color stability by the OptiShdade to obtain the CIE LAB values, the data was averaged and compared to obtain results. RESULTS: Statistical differences were found between the nanohybrid resins from different commercial houses, obtaining as results that wine was the one that most destabilized the color values (AE*), followed by coffee, the resin that obtained the most resistance in color stability was Filtek z. 250 of 3M soflex polish with a color difference of: (AE*: 1.12) and the one with the least resistance was the Llis resin from the FGM when exposed to wine with a value (AE*: 14.97) , the resin that had the most resistance to coffee was Brillant from Coltene with a value (AE*: 4.32) with rubber disc polishing and the resin that had the greatest pigmentation to coffee was the Llis resin from FGM with a value ( SA*: 11.0). CONCLUSION: Wine was the greatest pigmenting agent compared to coffee, since it produced greater changes in the color values in the four resins studied, the one with the greatest change was the Llis resin from the FGM commercial house, while the resin with the least changes it had was the Filtek z250 from the commercial house 3M.
