Clinical and SEM assessment of ART high-viscosity glass-ionomer sealants after 8-13 years in 4 teeth.

Resin composite sealants are retained longer than low-viscosity glass-ionomer sealants. Nevertheless, a systematic review showed that there is no evidence that resin composite sealants are superior to low-viscosity glass-ionomers in preventing dentine carious lesion development. This case study aimed to investigate reasons for this.
