X-ray diffraction analysis revealed \u03b1-Ca&lt;sub&gt;3&lt;\/sub&gt;(PO&lt;sub&gt;4&lt;\/sub&gt;), the high-temperature modification of enamel hydroxyapatite, thus indicating that the enamel melting temperature was above 1,000 \u00b0C in the interaction area of laser (continuous wave, 15 s exposure time, 1 mm spot size) and tissue. Powers of 0.5 and 1 W (continuous wave), 1.5 mm spot size, and 10 s exposure time vaporize and carbonize dentin tissue at the cavity bottom of class I preparation molars. The observed temperature rise of 4 \u00b0C indicates that thermal injury to the pulp tissue does not occur.<\/jats:p>","DOI":"10.1159\/000261437","type":"journal-article","created":{"date-parts":[[2009,11,24]],"date-time":"2009-11-24T03:28:15Z","timestamp":1259033295000},"page":"165-169","source":"Crossref","is-referenced-by-count":31,"title":["Laser Induced Molar Tooth Pulp Chamber Temperature Changes"],"prefix":"10.1159","author":[{"given":"I","family":"Ani\u0107","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.","family":"Vidovi\u0107","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Lui\u0107","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Tudja","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2009,11,19]]},"container-title":["Caries Research"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000261437","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T16:52:15Z","timestamp":1777481535000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000261437"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009,11,19]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000261437","archive":["Portico"],"relation":{},"ISSN":["0008-6568","1421-976X"],"issn-type":[{"value":"0008-6568","type":"print"},{"value":"1421-976X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009,11,19]]}}}
