ABSTRACT

El objetivo de este estudio fue determinar el porcentaje de retención y su efecto en la incidencia de caries oclusal de los sellantes de fosas y fisuras de ionómero de vidrio aplicados de acuerdo a la Técnica Restaurativa Atraumática (TRA), en una comunidad escolar con alto riesgo de padecer caries dental. Un total de 60 nuevos primeros molares permanentes erupcionados de 30 niños y niñas entre 6 y 8 años de edad del Centro Escolar Luisa de Marillac fueron seleccionados. Los sellantes fueron aplicados por un solo operador siguiendo la técnica de digito-presión descrita en el manual de la Organización Mundial de la Salud para la TRA. Ocho meses después de aplicados los sellantes, 48 (80%) fueron evaluados, encontrándose 27 (45%) retenidos y 21 (35%) ausentes. De los 27 sellantes retenidos, 12 (44.44%) estaban completamente retenidos y 15 (55.55%) parcialmente retenidos. Doce (20%) sellantes no fueron evaluados. En 3 (6.25%) primeros molares permanentes tratados se observó inicio de caries dental, mientras que en 45 (94.75%) de ellos no se observó inicio de caries. Aunque los sellantes de fosas y fisuras aplicados con TRA muestran un porcentaje de retención de menos del 50% después de 8 meses de aplicados en nuevos primeros molares permanentes, ésta técnica parece apropiada para poblaciones con alto riesgo de padecer caries dental.


The objective of this study was to determine the retention percentage and its effect on the incidence of occlusal caries of glass ionomer pit and fissure sealants applied according to the Atraumatic Restorative Technique (ART), in a high-risk school community of having tooth decay. A total of 60 new erupted permanent first molars from 30 boys and girls between 6 and 8 years of age from the Luisa de Marillac School Center were selected. The sealants were applied by a single operator following the digit-pressure technique described in the World Health Organization manual for ART. Eight months after the sealants were applied, 48 (80%) were evaluated, finding 27 (45%) retained and 21 (35%) absent. Of the 27 retained sealants, 12 (44.44%) were fully retained and 15 (55.55%) partially retained. Twelve (20%) sealants were not evaluated. In 3 (6.25%) of the first permanent molars treated, the onset of dental caries was observed, while in 45 (94.75%) of them there was no onset of caries. Although the fossa and fissure sealants applied with TRA show a retention percentage of less than 50% after 8 months of application in new first permanent molars, this technique seems appropriate for populations at high risk of suffering dental caries.
