Samples were immersed in calcification solution for 16 h and changes in crystal morphology were monitored by field emission scanning electron microscopy. Without fluoride, plate-like octacalcium phosphate crystals (20 nm thick, 2\u201310 \u03bcm wide) were formed. With 1\u201310 mg\/l fluoride, arrays of denser needle-like nanocrystals (20\u201330 nm wide, &gt;500 nm in length) were formed. We conclude that there is a minimal fluoride concentration (1 mg\/l) that dramatically affects the morphology of calcium phosphate crystals grown on etched enamel in vitro.<\/jats:p>","DOI":"10.1159\/000209346","type":"journal-article","created":{"date-parts":[[2009,3,25]],"date-time":"2009-03-25T14:41:06Z","timestamp":1237992066000},"page":"132-136","source":"Crossref","is-referenced-by-count":44,"title":["Effect of Fluoride on the Morphology of Calcium Phosphate Crystals Grown on Acid-Etched Human Enamel"],"prefix":"10.1159","volume":"43","author":[{"given":"Y.","family":"Fan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Z.","family":"Sun","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Moradian-Oldak","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,3,24]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00701082"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1177%2F10454411970080020301"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1177%2F154411130201300206"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016%2F0003-9969%2875%2990023-0"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1002%2Fadma.200502401"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.biomaterials.2008.10.019"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.biomaterials.2007.02.016"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1021%2Fcm00034a009"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1159%2F000163021"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.biomaterials.2004.05.009"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1007%2FBF00301634"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1159%2F000074360"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1159%2F000077752"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1600-0722.1996.tb00068.x"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1021%2Fj100615a007"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1600-0722.1996.tb00064.x"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1159%2F000077766"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1600-0722.1997.tb00231.x"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016%2FS0142-9612%2803%2900559-3"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1177%2F154405910608500415"},{"key":"ref21","doi-asserted-by":"publisher","DOI":"10.1016%2FS0142-9612%2897%2900232-9"},{"key":"ref22","doi-asserted-by":"publisher","DOI":"10.1038%2F433819a"},{"key":"ref23","doi-asserted-by":"publisher","DOI":"10.1177%2F154405910808700612"},{"key":"ref24","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.matlet.2007.01.040"},{"key":"ref25","doi-asserted-by":"publisher","DOI":"10.1002%2Fadfm.200500274"}],"container-title":["Caries Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/209346","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/209346","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T22:40:28Z","timestamp":1745448028000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000209346"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":25,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2009,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000209346","archive":["Portico"],"relation":{},"ISSN":["0008-6568","1421-976X"],"issn-type":[{"value":"0008-6568","type":"print"},{"value":"1421-976X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009]]}}}
