Abstract
Aim: Glassionomer cements (GICs) have been used for many years as restorative
materials, as luting cements or as temporary fillings. The aim of this study was to
evaluate the clinical performances of a glassionomer-based restorative system
for Class I, II and V permanent dental restorations.
Methodology: 4 experienced operators performed 380 dental restorations
using a resin-coated high-viscosity GIC (Equia Fil and Equia Coat, GC, Europe
NV, Belgium). Both vital and non-vital teeth were included and the use of dental
dam was registered to identify possible differences in survival rate. Follow-up
was scheduled at 3, 6, 12, 18, 24, 36 and 48 months, during which restorations
were assessed for survival, partial loss or failure, changes in color, texture and
integrity of surface and margins.
Results: 304 restorations in 202 patients were still included in the study
and evaluated after 48 months: 82 class I, 150 class II and 72 class V. Twentysix restorations out of 304 were lost, broken or seriously altered. They were
