Resumen
Because of the dissatisfaction that exists on the part of some pa-tients in relation to the color or tone of their dental organs, commercial com-panies have designed and produced toothpaste formulations with the intention of obtaining a whiter teeth effect. The objective of this study was to evaluate the effect of whitening toothpastes on the hardness, roughness and surface of the adamantine tissue. Forty-eight healthy permanent incisors, extracted due to periodontal disease, were collected and analyzed and they were divided into six study groups: Group 1: No Brushing, Group 2: Control (No Toothpaste) and four Experimental (Colgate Triple Action, Colgate Luminous White, Crest and Crest 3D). Adamantine structure was analyzed with a micro hardness tester, roughness with atomic force microscopy and the surface with scanning electron microscopy. For the statistical analysis we used the software MINITAB version 19. Significant differences were identified in the increase in dental micro hard-ness, topographic changes in the adamantine surface and different polishing patterns produced by the use of the different toothpastes used. A causa de la insatisfacción que existe por parte de algunos pacientes en relación con el color o tono de sus órganos dentarios, casas comer-ciales han diseñado y producido formulaciones de dentífricos con la intención de obtener un efecto de aclaramiento por parte de estos. El objetivo de este estudio fue evaluar el efecto de dentífricos aclaradores sobre la dureza, rugosi-dad y superficie del tejido adamantino. Se recolectaron y analizaron 48 incisivos permanentes sanos extraídos por enfermedad periodontal, se dividieron en seis grupos de estudio: Grupo 1: Sin cepillado, Grupo 2: Control (Sin pasta dental) y 4 experimentales (Colgate Triple Acción, Colgate Luminous White, Crest y Crest 3D). Se analizó la estructura adamantina con un micro durómetro, la rugosidad con microscopia de fuerza atómica y la superficie con microscopia electrónica de barrido. Para el análisis estadístico se utilizó el software MINI-TAB versión 19. Se identificaron diferencias significativas en el aumento en la microdureza dental, cambios topográficos en la superficie adamantina y dife-rentes patrones de pulido producidos por el uso de las diferentes pastas denta-les empleadas.
