Comparative Study on Adhesive Performance of Functional Monomers
Yasuhiro Yoshida,K. Nagakane,R. Fukuda,Y. Nakayama,Masayuki Okazaki,Hideaki Shintani,Satoshi Inoue,Yoh-ichi Tagawa,Kazuomi Suzuki,J. De Munck,B. Van Meerbeek +10 more
TL;DR: Besides self-etching dentin, specific functional monomers have additional chemical bonding efficacy that is expected to contribute to their adhesive potential to tooth tissue.
Journal ArticleDOI
Adhesion to and Decalcification of Hydroxyapatite by Carboxylic Acids
Yasuhiro Yoshida,B. Van Meerbeek,Y. Nakayama,Masayuki Yoshioka,J. Snauwaert,Yasuhiko Abe,Paul Lambrechts,Guido Vanherle,Masayuki Okazaki +8 more
TL;DR: An adhesion/decalcification concept was advanced that predicts that carboxylic acids, regardless of concentration/pH, either adhere to or decalcify hydroxyapatite, depending on the dissolution rate of the respective calcium salts in the acid solution.
Journal ArticleDOI
Bonding efficacy of polyalkenoic acids to hydroxyapatite, enamel and dentin.
R. Fukuda,Yasuhiro Yoshida,Y. Nakayama,Masayuki Okazaki,Satoshi Inoue,Hidehiko Sano,Kazuomi Suzuki,Hideaki Shintani,B. Van Meerbeek +8 more
TL;DR: The present findings indicate that the molecular structure of the polyalkenoic acid significantly influences the chemical bonding efficacy to Hap-based substrates.
Journal ArticleDOI
Gel Phase Formation at Resin-modified Glass-ionomer/Tooth Interfaces
Eduardo Coutinho,Yasuhiro Yoshida,Satoshi Inoue,R. Fukuda,Johan Snauwaert,Y. Nakayama,J. De Munck,Paul Lambrechts,Kazuomi Suzuki,B. Van Meerbeek +9 more
TL;DR: It is concluded that the self-adhesiveness of RMGIs should be attributed to ionic bonding to hydroxyapatite around collagen, and to micro-mechanical interlocking for those R MGIs that additionally hybridize dentin.
Journal ArticleDOI
Analysis of chemical interaction of 4-MET with hydroxyapatite using XPS.
Kouji Nagakane,Yasuhiro Yoshida,Isao Hirata,R. Fukuda,Y. Nakayama,Kenichi Shirai,Tatsuyuki Ogawa,Kazuomi Suzuki,Bart Van Meerbeek,Masayuki Okazaki +9 more
TL;DR: XPS spectra of HAp treated with 4-MET disclosed the surface to be enriched in calcium and decreased in phosphorus, indicating that phosphorus was extracted at a relatively higher rate than calcium.
