Er:YAG lasers have been recently used for this purpose with conflicting results. The effects of lasers on tooth demineralization and the effects of different combinations of laser treatments and bonding agents were evaluated in this study.<\/jats:p><jats:p><jats:bold>Methods:\u00a0<\/jats:bold> The enamel contents of fluorine, calcium oxide and phosphorus pentoxide (P<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub>) were analysed using acid etching, laser treatment or both. The tensile bond strength of metallic and ceramic brackets using Transbond<jats:sup>\u00ae<\/jats:sup> XT and Fuji Ortho<jats:sup>\u00ae<\/jats:sup> LC were also tested, using acid etching, laser treatment or a combination of both.<\/jats:p><jats:p><jats:bold>Results:\u00a0<\/jats:bold> All treatments reduced the contents of fluorine, P<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub> and calcium oxide, and acid reduced P<jats:sub>2<\/jats:sub>O<jats:sub>5<\/jats:sub> levels more than laser. The bond strength with laser was weaker than with acid, and stronger when combining both. When using laser, the best adhesive was the Fuji Ortho<jats:sup>\u00ae<\/jats:sup> LC. The combination of laser and acid produced the best results when using Transbond<jats:sup>\u00ae<\/jats:sup> XT.<\/jats:p><jats:p><jats:bold>Conclusions:\u00a0<\/jats:bold> The demineralization promoted by laser was lower than the one produced with acid. Laser treatment produced lower tensile stress strength than acid, but still enough to produce clinically efficient retention. The combination of laser and acid produced the best retention results.<\/jats:p>","DOI":"10.1111\/j.1834-7819.2012.01679.x","type":"journal-article","created":{"date-parts":[[2012,4,4]],"date-time":"2012-04-04T07:28:49Z","timestamp":1333524529000},"page":"190-195","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Enamel demineralization and bracket bond strength when etching with acid and\u200a\/or Er:YAG laser"],"prefix":"10.1111","volume":"57","author":[{"given":"MF","family":"Lasmar","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"VGS","family":"Reher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"R","family":"Lalloo","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P","family":"Reher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,4,4]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1177\/00220345550340060801"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/0022-3913(94)90436-7"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1117\/12.148319"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.2319\/120605-426R.1"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1159\/000261245"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ajodo.2006.04.055"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.4012\/dmj.24.596"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1067\/mpr.2000.108600"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1590\/S0103-64402008000100010"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0889-5406(05)81007-8"},{"key":"e_1_2_7_12_2","unstructured":"GrothEB.Comparative study of enamel conditioning with Er\u2010YAG laser and phosphoric acid: morphological analysis and resistance to traction (Portuguese).Faculty of Dentistry University of S\u00e3o Paulo 1997.PhD thesis."},{"key":"e_1_2_7_13_2","unstructured":"BispoBL.Enamel conditioning with Er:YAG laser and phosphoric acid: resistance to traction and surface electronic microscopy (Portuguese).Faculty of Dentistry University of S\u00e3o Paulo 2000.MSc dissertation."},{"key":"e_1_2_7_14_2","first-page":"107","article-title":"Comparative study of six orthodontic bracket types in relation to adhesion forces (Portuguese)","volume":"13","author":"Fleishman LA","year":"2008","journal-title":"R Dental Press Ortodon Ortop Facial"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1117\/12.17486"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10103-009-0704-1"},{"key":"e_1_2_7_17_2","doi-asserted-by":"publisher","DOI":"10.1089\/104454703768247765"},{"key":"e_1_2_7_18_2","doi-asserted-by":"publisher","DOI":"10.1089\/104454701750285421"},{"key":"e_1_2_7_19_2","doi-asserted-by":"publisher","DOI":"10.1002\/lsm.20247"},{"key":"e_1_2_7_20_2","doi-asserted-by":"publisher","DOI":"10.1177\/00220345960750011401"},{"key":"e_1_2_7_21_2","doi-asserted-by":"publisher","DOI":"10.1007\/s10103-009-0718-8"}],"container-title":["Australian Dental Journal"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1834-7819.2012.01679.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1111\/j.1834-7819.2012.01679.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,15]],"date-time":"2023-10-15T21:47:01Z","timestamp":1697406421000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1111\/j.1834-7819.2012.01679.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2012,4,4]]},"references-count":20,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2012,6]]}},"alternative-id":["10.1111\/j.1834-7819.2012.01679.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1834-7819.2012.01679.x","archive":["Portico"],"relation":{},"ISSN":["0045-0421","1834-7819"],"issn-type":[{"value":"0045-0421","type":"print"},{"value":"1834-7819","type":"electronic"}],"subject":[],"published":{"date-parts":[[2012,4,4]]},"assertion":[{"value":"2012-04-04","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
