The purpose of this study was to find out the more efficient method of tooth surface
treatment when the etched surface is contaminated by saliva. After the comparative
analyses on shear bond strengths of different test materials, fracture sites were
observed microscopically to evaluate the failure pattern of each group.
The results obtained were as follows
1. Shear bond strengths of contaminated groups were shown to be markedly lower
than those of control groups(p<.05) under the conditions with or without application of
bonding agent. General decline of shear bond strength with time was seen in all the
tested groups.
2. Comparison of shear bond strength between groups without application of bonding
agent, significant differences(p<.05) were found between all groups except group ¥´ and
¥· regardless of time intervals(p>.05).
3. In contaminated groups where bonding agent was applied with sealant, statistical
differences (p<.05) were found between all 1-day groups except group ¥³-¥µ and ¥³-¥·.
4. When the sealant was applied directly to the saliva-left tooth surface, the shear
bond strength of group ¥³ was shown to be superior to that of group ¥²(p<.05).
5. Based on the results above, it was demonstrated that the bond of sealant to tooth
surface is-greatly affected by saliva contamination and that the complete tooth isolation
method should be fully emphasized. The application of bonding resin is recommended
when performing sealant under the environment very susceptible to saliva contamination.
