| Research Abstract |
The purpose of this study was to determine effects of light curing of self-etching adhesives under ambient air or argon on inhibition depths and dentin bond strengths. Curing under ambient argon signi-cantly reduced oxygen inhibition at the free specimen surface and increased tensile bond strengths (TBS) to dentin during long period.
