Samples from seven patients, which contained residual biomaterial particles, were examined by field emission scanning electron microscopy and energy dispersive X\u2010ray spectroscopy was used to determine the composition of the remaining bone graft substitute material.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> Residual graft material occurred in isolated areas surrounded by bone and consisted of individual particles up to 1\u2003mm in length and smaller spherical granules. On the basis of 187 separate point analyses, the residual material was divided into three categories (A, B and C) consisting of: A, mainly CaS (S\/P atomic% ratio \u22652.41); B, a heterogeneous mixture of CaS and calcium phosphate (S\/P=0.11\u20132.4) and C, mainly calcium phosphate (S\/P\u22640.11; C), which had a mean Ca\u2003:\u2003P ratio of 1.63\u00b10.2, consistent with Ca\u2010deficient hydroxyapatite. Linescans and elemental maps showed that type C material was present in areas which appeared dense and surrounded, or were adjacent to, more granular CaS\u2010containing material, and also occurred as spherical particles. The latter could be disintegrating calcium phosphate in the final stages of the resorption process.<\/jats:p><jats:p><jats:bold>Conclusions: <\/jats:bold> CaS resorption in the human maxillary sinus is accompanied by CaP precipitation which may contribute to its biocompatibility and rapid replacement by bone.<\/jats:p>","DOI":"10.1111\/j.1600-0501.2008.01550.x","type":"journal-article","created":{"date-parts":[[2008,7,10]],"date-time":"2008-07-10T11:30:53Z","timestamp":1215689453000},"page":"814-822","source":"Crossref","is-referenced-by-count":17,"title":["Back\u2010scattered electron imaging and elemental microanalysis of retrieved bone tissue following maxillary sinus floor augmentation with calcium sulphate"],"prefix":"10.1111","volume":"19","author":[{"given":"Nicola","family":"Slater","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Amir","family":"Dasmah","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lars","family":"Sennerby","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mats","family":"Hallman","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Adriano","family":"Piattelli","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rachel","family":"Sammons","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,7,10]]},"reference":[{"key":"e_1_2_10_2_1","doi-asserted-by":"publisher","DOI":"10.1080\/13102818.2007.10817446"},{"key":"e_1_2_10_3_1","first-page":"655","article-title":"The versatility of calcium sulfate","volume":"20","author":"Bier S.J.","year":"1999","journal-title":"Compendium of Continuing Education in Dentistry"},{"key":"e_1_2_10_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/BF00297191"},{"key":"e_1_2_10_5_1","first-page":"869","article-title":"Augmentation of the maxillary sinus with calcium sulphate","volume":"14","author":"De Leonardis D.","year":"1999","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_10_6_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2000.71.6.940"},{"key":"e_1_2_10_7_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.1995.66.8.673"},{"key":"e_1_2_10_8_1","first-page":"1","volume-title":"Bone\u2010Bonding Biomaterials","author":"Ducheyne P.","year":"1992"},{"key":"e_1_2_10_9_1","first-page":"503","article-title":"Maxillary sinus augmentation using prehardened calcium sulfate","volume":"22","author":"Guarnieri R.","year":"2002","journal-title":"International Journal of Periodontics and Restorative Dentistry"},{"key":"e_1_2_10_10_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2004.75.6.902"},{"key":"e_1_2_10_11_1","first-page":"79","article-title":"Maxillary sinus augmentation using granular calcium sulfate (surgiplaster sinus)","volume":"26","author":"Guarnieri R.","year":"2006","journal-title":"International Journal of Periodontics and Restorative Dentistry"},{"key":"e_1_2_10_12_1","first-page":"31","volume-title":"Bone\u2010Bonding Biomaterials","author":"Kokubo T.","year":"1992"},{"key":"e_1_2_10_13_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2006.09.002"},{"key":"e_1_2_10_14_1","first-page":"493","article-title":"Comparison of three methods using calcium sulfate as a graft barrier material for the treatment of Class II mandibular molar furcation defects","volume":"22","author":"Maragos P.","year":"2002","journal-title":"International Journal of Periodontics and Restorative Dentistry"},{"key":"e_1_2_10_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbm.b.30636"},{"key":"e_1_2_10_16_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-051X.1999.260407.x"},{"key":"e_1_2_10_17_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbm.b.20012"},{"key":"e_1_2_10_18_1","doi-asserted-by":"publisher","DOI":"10.1902\/jop.2001.72.3.296"},{"key":"e_1_2_10_19_1","doi-asserted-by":"publisher","DOI":"10.1016\/S1079-2104(97)90043-3"},{"key":"e_1_2_10_20_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0011-8532(22)00070-2"},{"key":"e_1_2_10_21_1","doi-asserted-by":"publisher","DOI":"10.1046\/j.1365-2591.2001.00369.x"},{"key":"e_1_2_10_22_1","first-page":"866","article-title":"Short\u2010term healing following the use of calcium sulfate as a grafting material for sinus augmentation.
