Comparación Espectrofotométrica de las Sesiones de Blanqueamiento Intracameral con Peróxido de Hidrógeno y Carbamida a Diferentes Concentraciones

Abstract: RESUMEN: El objetivo del presente trabajo fue comparar espectrofotométricamente el número de sesiones para un cambio efectivo de coloración con peróxido de carbamida al 100 %, 37 % y peróxido de hidrógeno al 35 %, a través de la técnica Walking Bleach. Este fue un estudio experimental, in vitro, en paralelo, con ciego en la medición del efecto y en el análisis de datos. Se utilizaron 88 premolares extraídos por indicación ortodóncica. Estos fueron tratados endodónticamente y artificialmente pigmentados con cro… Show more
