RESUMO
Introducción: En la atención odontológica a niños es crucial seleccionar materiales restaurativos con buen rendimiento clínico y corto tiempo de aplicación, especialmente en pacientes con capacidad de atención limitada. Las resinas compuestas, con el mejoramiento de sus propiedades físicas y mecánicas, constituyen hoy uno de los materiales de mayor elección por el odontopediatra. Las resinas de relleno masivo son una alternativa atractiva para las restauraciones en el sector posterior. Objetivo: Comparar el grado de microfiltración marginal de resinas de relleno masivo y nanohíbrida en molares deciduos. Métodos: Estudio experimental, in vitro, en cuarenta molares deciduos; exodonciados por motivos terapéuticos, divididos en dos grupos. Grupo I: resina nanohíbrida con técnica incremental (Tetric® N Ceram - Ivoclar Vivadent) y Grupo II: resina de relleno masivo con técnica monoincremental (Tetric® N Ceram bulk fill - Ivoclar Vivadent). Se realizó un proceso de termociclado manual de 500 ciclos, entre 5 ºC ± 2 ºC y 55 ºC ± 2 ºC. Las muestras fueron sumergidas en azul de metileno al 0,5 por ciento durante 24 horas a 37 ºC. Se analizaron con el microscopio estereoscópico de luz a 40X. Resultados: Todas las muestras presentaron microfiltración. Con el uso de resina nanohíbrida, el 25 presentó microfiltración leve; el 30 por ciento, moderada; y el 45 por ciento, severa. En el grupo de la resina de relleno masivo, el 30 por ciento presentó microfiltración leve; el 35 por ciento, moderada; y el 35 por ciento, severa. No se encontró diferencia significativa entre ambos grupos (p = 0,55). Conclusiones: Ambas resinas, de relleno masivo y nanohíbrida, presentaron similar microfiltración marginal in vitro, en molares deciduos; por lo que la técnica de relleno masivo, por su fácil y rápida aplicación en un solo tiempo, es una buena alternativa en la rehabilitación dental odontopediátrica(AU)
Introduction: In children's dental care it is crucial to select restorative materials of proven clinical quality and a short application period, particularly with patients of limited attention capacity. Due to their improved physical and mechanical properties, composite resins are currently one of the materials of choice for children's dental care. Bulk fill resins are an attractive alternative for posterior restorations. Objective: Compare the degree of marginal microleakage of bulk fill and nanohybrid resins in deciduous teeth. Methods: An experimental in vitro study was conducted of 40 deciduous teeth extracted for therapeutic reasons, which were divided into two groups. Group I: nanohybrid resin by incremental technique (Tetric® N Ceram - Ivoclar Vivadent) and Group II: bulk fill resin by monoincremental technique (Tetric® N Ceram bulk fill - Ivoclar Vivadent). A manual 500-cycle thermocycling procedure was performed at 5ºC ± 2ºC to 55ºC ± 2ºC. The samples were soaked in 0.5 percent methylene blue at 37ºC for 24 hours and analyzed under a light stereo microscope at 40X. Results: Microleakage was present in all the samples. In the nanohybrid resin group, microleakage was mild in 25 percent, moderate in 30 percent and severe in 45 percent. In the bulk fill resin group, microleakage was mild in 30 percent, moderate in 35 percent and severe in 35 percent. No significant difference was found between the groups (p = 0.55). Conclusions: Both resins, bulk fill and nanohybrid, presented similar in vitro marginal microleakage in deciduous molars. The bulk fill technique is therefore a good alternative for children's dental rehabilitation, due to its easy and fast application in a single session(AU)

The purpose of this study is to compare atraumatic restorative treatment (ART) with the conventional rotational restorative method (CM) to determine in both cases the total time required for the procedure, the cost, the presence of pain, and the behavior of pediatric patients in Peru. Of the 30 children selected for the study, half received ART and restoration with glass ionomer cement and the other half, CM and restoration with amalgam. The study parameters were the times required to remove the decayed tissue and to complete the entire procedure, the total cost of the procedure, the presence of pain, and the patient's behavior during treatment. Significant differences were found between the two techniques in all parameters, except for the patient's behavior. Although removing the decayed tissue was faster with the CM, the entire procedure was faster with ART, which, moreover, was significantly less expensive and less painful than the CM. The results indicated that ART is a very good alternative due to its low cost and acceptance by the children.

El presente estudio se propuso comparar la práctica restaurativa atraumática (PRAT) con el método tradicional (MT) rotacional, con el objetivo de determinar en ambos casos el tiempo total del procedimiento, el costo, la presencia de dolor y el comportamiento en pacientes pediátricos de Perú. De los 30 niños y niñas seleccionados para el estudio, la mitad fueron sometidos a la PRAT y restauración con cemento de ionómero de vidrio y la otra mitad fueron tratados con el MT y restauración con amalgama. Los parámetros de análisis fueron los tiempos necesarios para remover el tejido cariado y el procedimiento operatorio total, el costo total del procedimiento, la manifestación de dolor y el comportamiento del paciente durante el tratamiento. Se hallaron diferencias significativas entre ambas técnicas en todos los parámetros, excepto en el comportamiento del paciente. Si bien la remoción del tejido cariado con el MT fue más rápida, el procedimiento completo fue más rápido en la PRAT, que además resultó significativamente menos costosa y menos dolorosa que el MT. Los resultados indicaron que la PRAT es una muy buena alternativa por su bajo costo y aceptación por parte de los niños.
