Evaluación de sistemas de acabado y pulido para resinas compuestas por estudiantes de odontología: estudio de preferencia del operador.

Abstract

This study aimed to evaluate user satisfaction and the impact of operator training on the use of two composite resin polishing systems, Ultradent’s Jiffy Original and FGM’s Diamond Master. Ten dental students were recruited and instructed to polish two resin blocks using both systems in two phases, initially without training and then with prior training. Their perceptions of the systems’ intuitiveness, ergonomic design, and initial and final results were recorded using a Likert scale survey. Statistical analyses, including Shapiro-Wilk and Wilcoxon tests, were performed to assess changes in user perceptions before and after training. The results showed that while there was a high level of initial satisfaction with both systems, training did not significantly alter perceived ease of use or effectiveness. Comparisons with previous literature revealed that different polishing systems can significantly influence the surface roughness and gloss of composite resins. The study highlights that although instruction did not dramatically change user perceptions, refining teaching methods to include more practice could further improve user satisfaction and clinical effectiveness. Future research should aim to bridge the gap between subjective user experiences and objective performance measures, ensuring that both are integrated into the evaluation of polishing systems.
