Resumen

Una adecuada higiene de las prótesis dentales constituye uno de los principales factores determinantes para la longevidad del tratamiento rehabilitador y el mantenimiento de la salud de la mucosa oral. Las soluciones desinfectantes se utilizan con frecuencia como agentes limpiadores de prótesis; sin embargo, sus efectos sobre las prótesis confeccionadas con resinas acrílicas no han sido suficientemente investigados. El objetivo de este estudio fue evaluar el efecto de la inmersión de un material acrílico termopolimerizable para bases de prótesis en una solución de extracto de incienso, durante diferentes períodos de tiempo (24 y 72 h), sobre el crecimiento de Candida albicans, la microdureza y la rugosidad superficial. Se prepararon un total de 90 especímenes para evaluar microdureza (n=30) y 60 para evaluación de la actividad antifúngica y la rugosidad superficial (n=30 para cada ensayo). Para cada prueba se establecieron  tres períodos de inmersión, con 10 especímenes por grupo. El cálculo del tamaño de la muestra se realizó utilizando G*Power. Inicialmente, los datos fueron sometidos a estadística descriptiva y se evaluó su distribución normal. Posteriormente, se realizaron análisis paramétricos mediante ANOVA y la prueba post hoc HSD de Tukey. Para todos los análisis se estableció un nivel de significancia de p < 0,05. Los resultados mostraron una inhibición del crecimiento de Candida albicans después de la inmersión en los extractos de incienso, así como un aumento de la microdureza en los grupos experimentales en comparación con el grupo control, independientemente del tiempo de inmersión. Asimismo, la solución limpiadora de prótesis a base de extracto de incienso produjo un incremento de la rugosidad superficial. En conclusión, los especímenes de resina acrílica mostraron un aumento de la dureza y de la rugosidad superficial, acompañado de una reducción del crecimiento fúngico en todos los especímenes evaluados.
