Pellicles were formed by exposing bovine enamel slabs to the oral environment at the buccal aspect of the upper first molars and at the lingual aspect of the lower incisors in 3 subjects over periods of 24 h. Enamel specimens with and without 24\u2013hour pellicles were immersed in citric acid (0.1 and 1%) for periods ranging from 30 s to 5 min, and processed for measurement of surface microhardness (SMH) and transmission electron microscopy (TEM). In comparison to uncovered enamel specimen significantly less decrease in SMH due to acid exposure was observed in pellicle\u2013coated enamel specimens. Pellicles formed at the buccal aspect of the upper molars were less effective in protecting the enamel against acid\u2013induced softening as compared to pellicles formed at the lingual aspect of the lower incisors only after 5 min exposure in 1% citric acid. TEM analysis showed that pellicle layers were dissolved continously due to acid exposure. However, even after 5 min exposure to 1% citric acid, a residual pellicle layer could be detected on the enamel surface. In conclusion, site\u2013dependent differences of buccally and lingually in vivo formed 24\u2013hour pellicles have minor importance concerning the pellicle\u2013induced protection of the enamel surface against erosive changes.<\/jats:p>","DOI":"10.1159\/000047446","type":"journal-article","created":{"date-parts":[[2003,4,15]],"date-time":"2003-04-15T12:11:24Z","timestamp":1050408684000},"page":"142-148","source":"Crossref","is-referenced-by-count":71,"title":["Protective Properties of Salivary Pellicles from Two Different Intraoral Sites on Enamel Erosion"],"prefix":"10.1159","volume":"35","author":[{"given":"M.","family":"Hannig","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Balz","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2001,3,9]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1159\/000016486"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1159\/000016536"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1159\/000016508"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1016\/0003-9969(86)90126-3"}],"container-title":["Caries Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/47446","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/47446","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,24]],"date-time":"2025-04-24T03:53:05Z","timestamp":1745466785000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000047446"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2001]]},"references-count":4,"journal-issue":{"issue":"2","published-online":{"date-parts":[[2001,4,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000047446","archive":["Portico"],"relation":{},"ISSN":["0008-6568","1421-976X"],"issn-type":[{"value":"0008-6568","type":"print"},{"value":"1421-976X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2001]]}}}
