Effect of LED curing on the marginal leakage of a pit and fissure sealant

Descripción del Articulo

The purpose of this study was to evaluate in vitro the curing effect of a light-emitting diode LED unit and conventional halogen light on the marginal leakage of a pit and fissure sealant. We used 40 caries-free permanent premolars recently extracted, which were randomly divided into two groups (n =...

We used 40 caries-free permanent premolars recently extracted, which were randomly divided into two groups (n = 20), sealed with a resin based fissure sealant, Helioseal F (Ivoclar Vivadent), according to the manufacturer patterns, then photopolymerized using either L.E.D. light or conventional halogen light (control group). The specimens were stored in distilled water at 37 ° C for 48 hours, and covered all tooth surfaces with nail enamel except for a margin of 2 mm around the sealants, the samples were then immersed in a 1% blue methylene dye solution as a marginal leakage indicator, and subjected to thermocycling regimen of 500 cycles between 5 °C and 60 °C. After removal of the dye solution specimens were sectioned lingual to vestibule way, to evaluated marginal leakage on a stereomicroscope. 35% and 60% of the sealants photopolymerized using either L.E.D. light or conventional halogen light showed some degree of marginal leakage, but the difference was not statistically significant (p> .05). The curing L.E.D. light or conventional halogen light has similar effects on the marginal leakage degree of a pit and fissure sealant.El propósito de éste estudio fue evaluar in vitro el efecto del fotocurado con luz emitida por diodos L.E.D. y luz halogena convencional en la filtracion marginal de un sellante de fosas y fisuras. Se emplearon 40 premolares permanentes libres de caries, recientemente extraídas, las que fueron aleatoriamente distribuidas en dos grupos (n=20), se les colocó sellante de fisura a base de resina, Helioseal F (Ivoclar Vivadent), de acuerdo a los patrones establecidos, fotopolimerizados ya sea con luz L.E.D. o luz halogena convencional (grupo control). Los especímenes fueron colocados en agua destilada a 37º C por 48 horas, luego se cubrieron todas las superficies dentarias con esmalte para uñas excepto un margen de 2 mm alrededor de los sellantes, se hizo el proceso de termociclado de las muestras, utilizando una solución de azul de metileno al 1% usado como indicador de la filtración marginal, el regimen fue de 500 ciclos entre 5° y 60°C. Luego los dientes fueron seccionados en sentido vestibulo lingual, para evaluar la filtracion marginal en un microscopio estereoscópico. El 35% y 60% de los sellantes fotopolimerizados con luz L.E.D. y luz halógena respectivamente presentaron algún grado de filtración marginal, pero ésta diferencia no mostró significancia estadística (p>0.05).
