Resumen
Una correcta fotopolimerización en odontología es fundamental para el éxito de las
restauraciones a largo plazo. Esta se encuentra sujeta a muchas variables que pueden alterar el rendimiento
final de la restauración, y como consecuencia, producir el fracaso del tratamiento, por lo que se considera
relevante manejar un conocimiento actualizado en la materia junto a un buen manejo de las técnicas de
fotocurado, teniendo en cuenta la creciente evolución tanto de los materiales como de las unidades de curado.
El objetivo de este estudio es sintetizar los factores involucrados en la fotopolimerización durante la realización
de restauraciones directas e indirectas en odontología, basado en evidencia científica reciente. Material y
Método: Se llevó a cabo una revisión sistemática exploratoria, utilizando las plataformas virtuales PubMed y
EBSCOhost, realizando 2 búsquedas homologadas en cada plataforma. Las búsquedas abarcaron los términos
Mesh: “Curing Lights, Dental”, “Polymerization”, “Composite Resins”, “Ceramics” y el término libre “Translucent
Zirconia”. Se seleccionaron estudios con un máximo de 5 años desde su publicación junto a la aplicación de
criterios de inclusión y exclusión. Resultados: Los factores identificados fueron las características deseables
de una lámpara de fotocurado, la implicancia del operador en el proceso y las características de los distintos
materiales resinosos (resinas bulk fill y convencionales) y cerámicos, incluyendo la nueva generación de
zirconias translúcidas, para un óptimo proceso de fotopolimerización. Conclusión: Se deben conocer todas las
características de la unidad de curado y realizar sus mantenciones periódicamente. Se sugiere contar con una
emisión radiante mínima de 1000 mW/cm2, un haz de luz homogéneo y una punta de mayor diámetro. Realizar
capacitaciones o entrenamientos al operador optimiza el fotocurado. Se deben respetar los grosores máximos
del material y trabajar con alta translucidez cuando sea posible.No hay suficientes estudios en relación a zirconia
translúcida.
A correct light curing technique in dentistry is crucial for a restauration´s long term success. This is related to many elements that can alter the restauration´s final result, which can also end in treatment failure. This is why it is important to keep an updated knowledge on the matter, along with a good clinical technique. Especially considering the increasing evolution on light curing supplies and units. This study aims to synthesize factors involved in light curing of direct and indirect dental restorations based on recent scientific evidence. Materials and methods: an exploratory systematic review was done using PubMed and EBSCOhost as virtual research platforms. Two equated researches were done on each platform. The researches used the following Mesh words: “Curing Lights, Dental”, “Polymerization”, “Composite Resins'', “Ceramics'' and the free term “Translucent Zirconia”. Using inclusion and exclusion criteria only 5 years since publication or recent studies where included. Results: The implied factors were the ideal features of the light curing unit, the influence of the operator in the light-curing process and the features of a variety of resin-based materials (Bulk Fill and conventional composite resins) and ceramics, which include the new generation of translucent zirconia for an optimal photopolymerization process. Conclusion: Features of the light-curing unit must be well known, and maintenance must be done regularly. A minimum of 1000 mW/cm2 of radiance source is recommended, as well as a homogeneous beam of light and a larger diameter tip. Operator training and preparation optimizes lightcuring. The maximum thickness on restoration material should be considered as well as working with high translucency when possible. There are not enough studies regarding translucent zirconia.
