Low-cost glass ionomer cement as ART sealant in permanent molars: a randomized clinical trial

Abstract

Low-cost glass ionomer cement as ART sealant in permanent molars: a randomized clinical trial Abstract: Clinical trials are normally performed with well-known brands of glass ionomer cement (GIC), but the cost of these materials is high for public healthcare in less-affluent communities. Given the need to research cheaper materials, it seems pertinent to investigate the retention rate of a low-cost GIC applied as atraumatic restorative treatment (ART) sealants in two centers in Brazil. Four hundred and thirty-seven 6-to-8-year-old schoolchildren were selected in two cities in Brazil. The children were randomly divided into two groups, according to the tested GIC applied in the first permanent molars. The retention rate was evaluated after 3, 6 and 12 months. Kaplan-Meier survival analysis and the log-rank test were performed. The variables were tested for association with sealant longevity, using logistic regression analyses (α = 5%). The retention rate of sealants after 12 months was 19.1%. The high-cost GIC brand presented a 2-fold-more-likely-to-survive rate than the low-cost brand (p < 0.001). Significant difference was also found between the cities where the treatments were performed, in that Barueri presented a higher sealant survival rate than Recife (p < 0.001). The retention rate of a low-cost GIC sealant brand was markedly lower than that of a well-known GIC sealant brand.

A 48-month randomized controlled trial of caries prevention effect of a one-time application of glass ionomer sealant versus resin sealant

“…The total retention rates were 7.5 and 40.0% in the GIS and RS groups, respectively, and the total and partial retention rates were 75 and 78.6%, respectively. Similar to the study of Hesse et al 31) in our study, partial loss of sealant was considered a failure. The cumulative sealant retention (full) rate over 48 months was 27.6% for the RS and 10.8% for the GIS in this study.…”

Are self‐etch adhesive systems effective in the retention of occlusal sealants? A systematic review and meta‐analysis

“…The most common material used to sealing occlusal surfaces seems to be resin – or glass–ionomer cement – based. Few studies are available confirming the effectiveness of other materials such as compomers.…”

Propiedades y aplicación clínica de los ionómeros de vidrio de alta densidad disponibles en Lima-Perú

“…estos materiales en dientes temporales con caries de clase I y II Black en niños entre 8 y 10 años y para los dientes temporales que permanecen más tiempo en la arcada dental, debemos hacer otra elección de material 29 . Los sellantes de fosas y fisuras realizados con Fuji IX tuvieron una tasa de sobrevivencia del doble de tiempo con respecto al ionómero de bajo precio 30 . Hay mayor fracaso en clase II de tres superficies (MOD), que en clase II de dos superficies.…”
