Actualmente, el disilicato de litio destaca como uno de los materiales más ampliamente utilizados en la odontología restaurativa, lo cual genera la necesidad de estudiar sus propiedades bajo distintos contextos. Este estudio se propuso evaluar el impacto de dos sistemas de pulido, Diapro TWIST y LS Gloss Charside, en la rugosidad de esta cerámica. Para ello, se seleccionaron 32 muestras de cerámica de disilicato de litio, divididas equitativamente en dos grupos, cada uno sometido a un sistema de pulido diferente. Las mediciones de rugosidad superficial se realizaron antes y después del proceso de pulido en tres áreas distintas de la superficie vestibular de cada muestra, utilizando el parámetro de rugosidad Ra. Los resultados revelaron que el Sistema B (LS Gloss Charside) logró una reducción significativa de la rugosidad superficial en comparación con el Sistema A (Diapro TWIST) y el grupo control, confirmando la hipótesis inicial. A pesar de estos hallazgos alentadores, las limitaciones del estudio incluyen su enfoque in vitro, que limita la extrapolación directa de los resultados a la práctica clínica y la evaluación de un número limitado de sistemas de pulido. Esto sugiere la necesidad de futuras investigaciones que aborden una variedad más amplia de sistemas y condiciones clínicas. Este estudio ofrece una visión precisa sobre la influencia de diferentes sistemas de pulido en la rugosidad superficial de la cerámica de disilicato de litio y destaca la relevancia clínica de la selección cuidadosa de sistemas de pulido para obtener resultados óptimos en restauraciones dentales duraderas y estéticamente satisfactorias.
Currently, lithium disilicate stands out as one of the most widely used materials in restorative dentistry, creating a need to study its properties in various contexts. This study aimed to evaluate the impact of two polishing systems, Diapro TWIST and LS Gloss Charside, on the roughness of this ceramic. For this purpose, 32 samples of lithium disilicate ceramic were selected, divided equally into two groups, each subjected to a different polishing system. Surface roughness measurements were taken before and after the polishing process in three distinct areas of the vestibular surface of each sample, using the Ra roughness parameter. The results revealed that System B (LS Gloss Charside) achieved a significant reduction in surface roughness compared to System A (Diapro TWIST) and the control group, confirming the initial hypothesis. Despite these encouraging findings, the study's limitations include its in vitro focus, which limits the direct extrapolation of the results to clinical practice, and the evaluation of a limited number of polishing systems, suggesting the need for future research that addresses a wider variety of systems and clinical conditions. This study provides an accurate insight into the influence of different polishing systems on the surface roughness of lithium disilicate ceramic, highlighting the clinical relevance of the careful selection of polishing systems to achieve optimal results in durable and aesthetically pleasing dental restorations.
