Análisis del desempeño de los estudiantes de odontología en el manejo de resinas compuestas de diferentes viscosidades: un estudio sobre las preferencias y la eficacia de los operadores.

Abstract

Composite resins (CRs) are widely used in dentistry for dental restorations due to their versatility and ability to mimic the natural appearance of teeth. They are made of an organic matrix, inorganic fillers, bonding agents, and pigments, and their success depends largely on the operator's skill in handling them. This study evaluated the perception and experience of dental students when handling CRs of different viscosity levels. Participants manipulated and modeled various CRs, and their perceptions were recorded through a questionnaire, focusing on factors such as viscosity that affect handling. The results showed that Durafill® VS was rated as the most difficult to manipulate, with the highest average difficulty score and greater variability in participants' responses. In contrast, Brilliant EverGlow® was rated the easiest to manipulate, with lower variability. One-way ANOVA analysis indicated no significant differences in perceived difficulty among the three resins (p > 0.05). Brilliant EverGlow® was also rated as the stickiest and hardest resin, while Durafill® VS was considered the least hard. These findings suggest the need for improved training on the handling of RC resins, especially those with higher viscosities, to improve operator experience and clinical outcomes. Recommendations include the development of new protocols and techniques to optimize restorative procedures, ultimately leading to more effective and long-lasting treatments.
