          Abstract

          INTRODUCCIÓN:el objetivo de este estudio fue determinar si el entrenamiento, consistente en entrega de contenidos teóricos y el uso de un programa computacional, mejora a corto plazo la discriminación visual de la dimensión más importante en la selección de color dentario: la luminosidad. MÉTODOS: 451 estudiantes que cumplieron con los criterios de inclusión, participaron del estudio firmando un consentimiento informado. Cada uno debió ordenar las 16 muestras de la guía Vitapan Classical, de mayor a menor luminosidad, según escala del fabricante. Este procedimiento se realizó con el código de identificación cubierto, en un tiempo de 3 min, bajo luz día, sobre un fondo de color gris neutro. Se hizo una primera ordenación sin entrenamiento. Posteriormente se realizó el entrenamiento que consistió en una clase teórica de 45 min y práctica durante 1 hora, utilizando los 7 grupos de ejercicios del programa computacional Color training exercises. Finalmente, cada participante hizo una segunda ordenación a la semana siguiente del entrenamiento. Los resultados fueron comparados usando el test T de Student para muestras pareadas. RESULTADOS:en la primera ordenación se obtuvo un porcentaje de aciertos de 33,3% y luego del entrenamiento un promedio de 33,6%. No se observaron diferencias significativas (p = 0,8520). CONCLUSIONES:con las limitaciones propias del estudio, la entrega de contenido teórico más el entrenamiento visual mediante el uso de programa computacional, no es efectivo en mejorar, a corto plazo, la discriminación visual de luminosidad de color dentario en los sujetos en estudio

          INTRODUCTION: the objective of this study was to determine whether a short training workshop including theoretical instruction and the use of a computer program improves visual discrimination of the most important dimension in tooth color selection: luminosity. METHODS: 51 students who met the inclusion criteria participated in the study after signing an informed consent. Each student was asked to arrange 16 samples of the Vitapan Classical Guide from highest to lowest luminosity according to the manufacturer’s scale. This procedure was done in 3 minutes with covered identification codes, under daylight, and against a neutral gray background. This first arrangement was done with no prior instruction. Training was provided afterwards and consisted of a 45-minute theoretical class and one-hour practicum using the 7-exercise groups of the Color Training Exercises computer program. Finally, each participant made a second arrangement one week after the training workshop. The results were compared using the Student T-test for paired samples. RESULTS: the first arrangement yielded 33.3% of success and after training there was 33.6% success in average. There were no significant differences (p = 0.8520). CONCLUSIONS: considering the limitations of the study, providing a short theoretical workshop plus visual training using a computer program is not effective in improving visual discrimination of tooth color luminosity in the study subjects.

          Assessment of appearance match by visual observation and clinical colorimetry.

          Judgments of appearance matching by means of the visual criteria established by the United States Public Health Service (USPHS) and by means of an extended visual rating scale were determined for composite resin veneer restorations and their comparison teeth. Using a colorimeter of 45 degrees/0 degrees geometry and the CIELAB color order system we used the color of the restorations and comparison teeth to calculate a color difference for every visual rating. Statistically significant relationships were found between each of the two visual rating systems and the color differences. The average CIELAB color difference of those ratings judged a match by the USPHS criteria was found to be 3.7. However, the overlap in ranges of the color differences for those comparisons rated matches and mismatches indicates the importance of other factors in appearance matching, such as translucency and the effects of other surrounding visual stimuli. The extended visual rating scale offers no advantages to the more broadly defined criteria established by the USPHS.
