However, few thermodynamic studies have been aimed at the elucidation of the interfacial terms. Contact angle measurements (sessile drop and thin layer wicking) and kinetic dissolution and growth techniques have been used to study the interfacial properties of root dentin (D), human enamel (E), and hydroxyapatite (HAP). The interfacial tensions between water (w) and each of these phases were calculated from contact angle data according to surface tension components theory.

Kinetics studies of the crystallization of HAP on HAP, dentin, and enamel yielded the interfacial free-energy values, \u03b3\n                    <jats:sub>wHAP<\/jats:sub>\n                    = 17.1 x 10\n                    <jats:sup>-3<\/jats:sup>\n                    J m\n                    <jats:sup>-2<\/jats:sup>\n                    , 17.7 x 10-3J m\n                    <jats:sup>-2<\/jats:sup>\n                    , and 9.4 x 10-3J m\n                    <jats:sup>-2<\/jats:sup>\n                    , respectively, probably reflecting the interfacial energies of the deposited phases rather than those of the dental hard-tissue substrata. The lower interfacial tension values are consistent with the higher solubilities of these solid phases: logKso = -52.0, -55 - 57, and -58 - 59, for root dentin, enamel, and HAP, respectively, expressed as an equivalent HAP ionic product. The higher interfacial free-energy is also consistent with the slower mineralization of HAP on dentin and enamel surfaces.\n                  <\/jats:p>","DOI":"10.1177\/08959374970110042601","type":"journal-article","created":{"date-parts":[[2009,1,8]],"date-time":"2009-01-08T19:41:28Z","timestamp":1231443688000},"page":"566-575","source":"Crossref","is-referenced-by-count":23,"title":["The Relationship between Surface Free-Energy and Kinetics in the Mineralization and Demineralization of Dental Hard Tissue"],"prefix":"10.1177","volume":"11","author":[{"given":"W.","family":"Wu","sequence":"first","affiliation":[{"name":"Department of Chemistry 756 Natural Sciences Complex State University of New York at Buffalo Buffalo, New York 14260-3000, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.H.","family":"Nancollas","sequence":"additional","affiliation":[{"name":"Department of Chemistry 756 Natural Sciences Complex State University of New York at Buffalo Buffalo, New York 14260-3000, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[1997,11,1]]},"reference":[{"key":"atypb1","doi-asserted-by":"publisher","DOI":"10.1177\/00220345810600100901"},{"key":"atypb2","first-page":"219","volume":"5","author":"Arends J.","year":"1977","journal-title":"J Biol Buccale"},{"key":"atypb3","doi-asserted-by":"publisher","DOI":"10.1159\/000260700"},{"key":"atypb4","doi-asserted-by":"publisher","DOI":"10.1149\/1.2403829"},{"key":"atypb5","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0248(67)90034-6"},{"key":"atypb6","first-page":"921","volume":"43","author":"Brauer GM","year":"1964","journal-title":"J Dent Res"},{"key":"atypb7","doi-asserted-by":"publisher","DOI":"10.1177\/08959374870010022301"},{"key":"atypb8","doi-asserted-by":"publisher","DOI":"10.1098\/rsta.1951.0006"},{"key":"atypb9","doi-asserted-by":"publisher","DOI":"10.1177\/00220345860650050601"},{"key":"atypb10","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0248(92)90568-4"},{"key":"atypb11","doi-asserted-by":"publisher","DOI":"10.1177\/00220345820610010101"},{"key":"atypb12","doi-asserted-by":"publisher","DOI":"10.1159\/000260795"},{"key":"atypb13","doi-asserted-by":"publisher","DOI":"10.1016\/0022-0248(91)90012-T"},{"key":"atypb14","first-page":"955","volume":"65","author":"Foreman PC","year":"1989","journal-title":"J Dent Res"},{"key":"atypb15","volume-title":"A dual constant composition study of the mineralization kinetics of hydroxyapatite and human dental enamel (PhD dissertation).
