| Research Abstract |
The results of the research project reviled that the adhesive interface degraded over time. Moist bonding systems showed greater degradation with the extraction of resin within the hybrid layer and depletion of collagen fibrils compared to self-etching systems both in vivo and in vitro. Release of endocrine disrupter from resins were undetectable from both short- and long-term experiment in vivo.
