Objects: One of the major concerns with highly-viscous glass ionomer cements (HVGICs) is their ability to achieve effective initial interfacial gap-formation in restorative
cavities. This in vitro study examined the initial stage (after one-day storage) of interfacial
gap-formation in Class I restoration together with determination of associated mechanicalproperties (compressive strength and flexural strength).
Materials and Methods: Cavity preparation was made in occlusal surface of premolar
teeth. Five HV-GICs were studied (Ketac Universal Aplicap, Ketac Molar Aplicap: 3M,Fuji IX GP, Fuji IX EXTRA, EQUIA Forte: GC, and two conventional glass-ionomercements (C-GICs, Ketac Silver Aplicap: 3M, Fuji II: GC, as controls), with specimen
sub-groups (n = 10 / group) for each property measured. After one-day storage andpolishing, the restored teeth were sectioned in a mesio-distal direction through the centerof the model Class I restorations. The presence or absence of interfacial-gaps wasmeasured at x 1000 magnification at 14 points (each 0.5-mm apart) along the cavity
restoration interface; (n=10; total points measured per group =140). Compressive andflexural strengths were measured (n = 10 / group), as described above.
Result: For HV-GICs and C-GICs, significant differences (p<0.05) in gap-incidence wereobserved. In the former case, 4-14 gaps were found. In the latter case, 21-24 gaps wereobserved. The compressive and flexural strengths of HV-GICs significantly increased
compared to C-GICs.
Conclusions: It is thought that a HV-GIC is the useful and significant restorative material
for some pediatric or geriatric patients.
Key Words: Highly-viscous glass-ionomer cement, Filling, Interfacial Gap-formation,
Class I restoration, Mechanical properties.
