We have here investigated the extent to which the self-adhesiveness of resin-modified glass-ionomers (RMGIs) can be attributed to this chemical bonding capacity. Therefore, the interaction of 3 RMGIs with tooth substrates was comprehensively characterized, with electron and atomic force microscopy correlated with x-ray photoelectron spectroscopy (XPS). Interfacial ultrastructural analysis for 2 RMGIs disclosed a shallow hybridization of hydroxyapatite-coated collagen, on which a submicron gel phase was deposited through reaction of the polyalkenoic acid with calcium extracted from the dentin surface. One RMGI, however, bonded to dentin without hybrid layer or gel phase formation. XPS indicated that polycarboxylic acids included in the RMGIs electrostatically interacted with hydroxyapatite. We conclude that the self-adhesiveness of RMGIs should be attributed to ionic bonding to hydroxyapatite around collagen, and to micro-mechanical interlocking for those RMGIs that additionally hybridize dentin.<\/jats:p>","DOI":"10.1177\/154405910708600714","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T19:39:42Z","timestamp":1231443582000},"page":"656-661","source":"Crossref","is-referenced-by-count":67,"title":["Gel Phase Formation at Resin-modified Glass-ionomer\/Tooth Interfaces"],"prefix":"10.1177","volume":"86","author":[{"given":"E.","family":"Coutinho","sequence":"first","affiliation":[{"name":"Leuven BIOMAT Research Cluster-Department of Conservative Dentistry, School of Dentistry, Oral Pathology and Maxillo-Facial Surgery, Catholic University of Leuven, Kapucijnenvoer 7, B-3000, Leuven, Belgium;"},{"name":"Department of Biomaterials Science, Okayama University Graduate School of Medicine, Dentistry and Pharmaceutical Science, Okayama, Japan;"},{"name":"Division for General Dentistry, Hokkaido University Dental Hospital, Sapporo, Japan;"},{"name":"Department of Operative Dentistry and Dental Materials, Hiroshima University Graduate School of Biomedical Sciences, Hiroshima, Japan;"},{"name":"Laboratory for Molecular and Nanomaterials, Department of Chemistry, Catholic University of Leuven, Belgium;
