The aim of this study was to assess, on a 3-years interval time (6, 12, 24, 36 months), the retention degree of some glass-ionomer type sealers, as well as their clinical efficiency. The research was performed on a 15 patients study group, with age between 8-16 years. A number of 42 sealings were performed using two sealing products: Fuji TRIAGE (GC, Leuven, Belgium) and Ketac Molar (3M ESPE, Seefeld, Germany). The sealing materials were applied using ART technique. The sealings were analysed at 6, 12, 24, 36 months. The study also assessed the frequency rate of new occlusal dental caries and the evolution stage of old dental caries. After 6 months, 88.1% of sealings were unaffected and 11.9% partially present. After 18 months, only 57.2% of sealings were unaffected, while 42.8% were partially present. After 24 months, 54.7% of sealings were partially present and 9.5% were absolutely absent. After 36 months, 35.7% of sealings were partially present, while 33.3% were absent. In all sealed surfaces was not recorded any new dental caries. For surfaces diagnosed with non-cavitary dental caries, were recorded after 18 months one new dentinal carious lesion, after 24 months two new dentinal carious lesions and after 36 month three new dentinal carious lesions. The results obtained in this study sustain and recommend the use of high viscosity glass-ionomer sealers for the sealing of occlusal surfaces. The results regarding clinical efficiency of glass-ionomer sealers showed that best results are obtained in the first 12 months, comparing with time intervals of 24 months and 36 months.
