Development of a Self-etch Adhesive for Resin-modified Glass Ionomers

E. Coutinho, K. Van Landuyt, J. De Munck, A. Poitevin, Y. Yoshida, S. Inoue, M. Peumans, K. Suzuki, P. Lambrechts, and B. Van Meerbeek
The self-etch technique is a promising approach to ionomer-tooth interfaces, since it enhances the user-friendliness of resin-modified glass ionomers and lowers their technique-sensitivity.
