echol-Functionalized Synthetic Polymer as a Dental

2015-7-15 · This study reports a synthetic polymer functionalized with echol groups as dental adhesives. We hypothesize that a echol-functionalized polymer functions as a dental adhesive for wet dentin surfaces, potentially eliminating the compliions associated with saliva contamination. We prepared a random copolymer containing echol and methoxyethyl groups in the side chains.
