The Effect of Brushing and Aging on the Staining and Smoothness of Resin Composites

Abstract

Staining and surface degradation of the resin composites was reduced, but not prevented by brushing alone. Thus, minimizing the restoration exposure to staining substances is important for maintaining the aesthetic appearance of the restoration. (J Esthet Restor Dent 29:E44-E55, 2017).

Characterization of low-cost Brazilian resin composites submitted to tooth brushing

“…The same results of this morphological analysis were found in previous studies. 24 As stated by Ruivo et al, 25 the greater the interparticle spacing, the less protected the soft resin matrix against challenges, such as brushing. A point to be borne in mind herein is that roughness values above 0.2 µm allow greater biofilm retention, representing a disadvantage to any material that may be used.…”

Effect of Interval Time between Corrosive and Abrasive Challenges on a Nanoparticulate Composite Resin

“…Moreover, the association of soft-bristle toothbrush and low-abrasive dentifrice did not increase roughness for nanofilled and microfilled materials. 8 An inadequate oral environment, with episodes of corrosive and abrasive challenges, can promote some properties changes of the composite resin. 22 The hardness of the composite resin is an important property for evaluating the resistance of this material to indentation.…”

“…7 However, toothbrush and toothpaste can negatively affect the smoothness surface of composite resin according to the abrasiveness of the dentifrice, stiffness of toothbrush bristles, and major associated with acidic diet. 8 The consumption of sports and energy drinks is currently increasing, mainly due to the population's greater concern about health and body aesthetics. 9 Moreover, beverages present low pH (3.8-2.3) generates dental corrosion 10 and cause degradation of the composite resin organic matrix, increasing the surface roughness and decreasing hardness and flexural strength.…”

Comparación in vitro de la microdureza y rugosidad superficial de resinas bulk fill después del desafío abrasivo con una pasta dental blanqueadora

“…( (31) En el estudio de De Moraes, et al2018 (19) menciona que no hay diferencias en la rugosidad superficial en esmalte dental luego de un desafío abrasivo con pasta blanqueadora por 90 días, sin embargo si encontraron cambios de color perceptibles. Mientras que en el estudio de Mozzaquatro L, et al2017 (21)…”

“…Por otro lado, existen otras consecuencias tales como recesiones gingivales y abrasión en la zona cervical. (11)(12) (13) No obstante, otros autores contradicen esta hipótesis indicando que el uso de pastas blanqueadoras no genera cambios significativos en la superficie del esmalte (33) y en resinas compuestas (21) . Además, hallaron que no existe diferencia entre el uso de pasta blanqueadora vs convencional, considerando que la cantidad de abrasión producida depende de la cantidad de abrasivo, tamaño y forma de partículas (33,21) Para obtener un éxito clínico a largo plazo en restauraciones adhesivas se requiere de parámetros aceptables de anatomía, color, desgaste, filtración marginal, etc.…”
