The purpose of this study was to compare the marginal leakage of resin liner which
was used as a liner to amalgam restoration. Control group composed of no liner group,
copalite group and experimental group comp Bed of All-bond 2, Vitrebond, Superbond
D-liner applied groups were evaluated. Cl.V preparation with a size of 3¡¿2¡¿1.5mm on
70 extracted primary molars were made and applied appropriate liners for each groups.
After amalgam filling and polishing, polished specimens underwent temperature changed
from 5¡É to 55¡É a thousand times. After thermocycling, specimens were placed in 2%
methylene blue dye solution for hours in an incubator set at 37¡É. The teeth were
sectioned buccolingually and the degree of dye penetration was observed with a
spectroscopy.(¡¿30) The following results were obtained.
1. Vitrebond, All-bond 2, Superbond D-liner group exhibited a statistically significant
low, degree of dye penetration than no liner and copalite group. (Kruskal-Wallis analys
P<0.05)
2. No liner group and copalite group exhibited a similar degree of dye penetration. (Man
Whitney analysis, p>0.05)
3. All-bond 2 group exhibited a statistically significant lower degree of dye penetration
than Vitrebond group,(Menn-Whitney analysis, P<0.05) Superbond D-liner group also
exhibited a lower degree of dye penetration than Vitrebond group but was statistically
insignficant(Mann-Whitney analysis, P>0.05)
