Sodium and potassium alginates were extracted at the pilot plant scale from the giant kelp, Macrocystis pyrifera, from Bahía Tortugas, Baja California Sur, Mexico. Alginates were coded as S1, S2 and S3 for sodium alginate, and as P1, P2 and P3 for potassium alginate. The average viscosities of the s...

Results showed that dental impresion material prepared with sodium alginate with extra low viscosities (S1 = 58 mPa s) and low viscosities (S2 = 145 m Pa s) did not form gels, the material prepared with medium viscosity (S3 = 506 mPa s) produced a gel type II (regular set) in 70% of the 10 formulations experimented, and the material prepared with potassium alginate with extra low viscosity (P1 = 48 mPa s) produced a gel type II in 90% of the formulations. Using potassium alginate with low viscosity (P2 = 155 mPa s), 90% of the formulations were type I (fast set), and using potassium alginate with medium viscosity (P3 = 200 mPa s), 80% of the formulations were type I. The highest compressive strength was obtained using sodium alginate of 506 mPa s and the three potassium alginates experimented at 25% concentration, with values of 2474, 1209, 2101 and 2124 g cm–2 for S3, P1, P2 and P3 alginates, respectively. The elasticity order of formulation with 25% alginates compared with a commercial product (Jeltrate®) was as follows: Jeltrate® > P2 > S3 > P3 > P1. It was concluded that S3, P1, P2 and P3 alginates have good potential for use in the production of dental impression materials.
Se extrajeron alginatos de sodio y de potasio a escala piloto del alga Macrocystis pyrifera proveniente de Bahía Tortugas, Baja California Sur, México. Los alginatos fueron codificados como alginatos de sodio (S1, S2 y S3) y alginatos de potasio (P1, P2 y P3). Las viscosidades medias de los alginatos de sodio y de potasio en solución acuosa al 1% fueron de 58, 145 y 506 mPa s, y 48, 155 y 200 mPa s, respectivamente. Los resultados mostraron que el material para impresiones dentales preparado con los alginatos de sodio con viscosidades extra bajas (S1= 58 mPa s) y viscosidades bajas (S2 = 145 mPa s) no formó geles, el material preparado con viscosidades medias (S3 = 506 mPa s) produjo geles tipo II (fraguado normal) en 70% de las 10 formulaciones experimentadas, y el material preparado con alginatos de potasio con viscosidad extra baja (P1 = 48 mPa s) produjo geles tipo II en 90% de las formulaciones. Usando alginatos de potasio con viscosidad baja (P2 = 155 mPa s), 90% de las formulaciones fueron de tipo I (fraguado rápido), y usando alginato de potasio con viscosidad media (P3 = 200 mPa s), 80% de las formulaciones fueron de tipo I. La más alta resistencia a la compresión fue obtenida usando alginato de sodio de 506 mPa s y los tres alginatos de potasio experimentados a concentración de 25%, con valores de 2474, 1209, 2101 y 2124 g cm–2 para los alginatos S3, P1, P2 y P3, respectivamente. El orden de elasticidad de las formulaciones con 25% de alginatos comparados a un producto comercial (Jeltrate®) fue el siguiente: Jeltrate® > P2 > S3 > P3 > P1. Se concluye que los alginatos S3, P1, P2 y P3 tienen un buen potencial para usarse en la producción de material de impresión dental. |
