Korijenski kanali svih zuba iz uzorka biti \u0107e endodontski obra\u0111eni po jednakom protokolu. Biti \u0107e provedena hemomehani\u010dka obrada kanala uz upotrebu endomotora, ma\u0161inskih instrumenata za obradu kanala jednakog promjera. Uzorak \u0107e biti podijeljen u 5 grupa po 20 zuba; pozitivna kontrolna grupa napunjena samo gutaperka ko\u010di\u0107em bez silera, negativna kontrolna grupa sa prekrivenim apeksom korijena, tre\u0107a grupa zubi punjeni sa silerom na bazi epoksi-amin smole i gutapreka ko\u010di\u0107em, \u010detvrta grupa zubi punjeni sa silerom na bazi kalcij hidroksida i gutaperka ko\u010di\u0107em i peta grupa zubi punjeni sa silerom na bazi mineraltrioksid agregata i gutaperka ko\u010di\u0107em. Za dokazivanje apikalnog mikrocurenja koristit \u0107e se metoda Metoda ekstrakcije boje. Uzorci \u0107e zatim biti prekriveni lakom, osim apikalnog dijela u du\u017eini od 1 mm, te \u0107e biti uronjeni u 2% metilensko plavu boju na 37\u00b0C 72 sata. Nakon toga, svaki uzorak bi\u0107e uronjen u mali kontejner koji sadr\u017ei 1ml svje\u017ee pripremljene 65% HNO3 naredna 72 sata. Dobiveni rastvor \u0107e se u posebnim posudama centrifugirati na 14000 obrtaja 5 minuta da bi se razdvojio dobiveni debris od ekstrahirane boje. Koncentracija boje \u0107e se zatim odrediti UV spektrofotometrom na 550 nm valne du\u017eine.<br><strong>Upravljanje projektom: <\/strong>Priprema uzoraka vr\u0161it \u0107e se u laboratorijama Stomatolo\u0161kog fakulteta, dok \u0107e se ispitivanja provesti u laboratorijama Fakulteta zdravstvenih studija uz zajedni\u010dku saradnju.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><br><strong>Klju\u010dne rije\u010di: apikalno mikrocurenje, metoda ekstrakcije boje, endodontski sileri, UV spektrofotometrija<\/strong><\/p>\n\n\n<style>.wp-block-kadence-advancedbtn.kb-btns1339_df677d-ee{gap:var(--global-kb-gap-xs, 0.5rem );justify-content:center;align-items:center;}.kt-btns1339_df677d-ee .kt-button{font-weight:normal;font-style:normal;}.kt-btns1339_df677d-ee .kt-btn-wrap-0{margin-right:5px;}.wp-block-kadence-advancedbtn.kt-btns1339_df677d-ee .kt-btn-wrap-0 .kt-button{color:#555555;border-color:#555555;}.wp-block-kadence-advancedbtn.kt-btns1339_df677d-ee .kt-btn-wrap-0 .kt-button:hover, .wp-block-kadence-advancedbtn.kt-btns1339_df677d-ee .kt-btn-wrap-0 .kt-button:focus{color:#ffffff;border-color:#444444;}.wp-block-kadence-advancedbtn.kt-btns1339_df677d-ee .kt-btn-wrap-0 .kt-button::before{display:none;}.wp-block-kadence-advancedbtn.kt-btns1339_df677d-ee .kt-btn-wrap-0 .kt-button:hover, .wp-block-kadence-advancedbtn.kt-btns1339_df677d-ee .kt-btn-wrap-0 .kt-button:focus{background:#444444;}<\/style>\n<div class=\"wp-block-kadence-advancedbtn kb-buttons-wrap kb-btns1339_df677d-ee\"><style>ul.menu .wp-block-kadence-advancedbtn .kb-btn1339_ddfcf8-3c.kb-button{width:initial;}.wp-block-kadence-advancedbtn .kb-btn1339_ddfcf8-3c.kb-button{padding:var(--kb-btn-padding);margin:var(--kb-btn-margin);box-shadow:none;}.wp-block-kadence-advancedbtn .kb-btn1339_ddfcf8-3c.kb-button:hover, .wp-block-kadence-advancedbtn .kb-btn1339_ddfcf8-3c.kb-button:focus{box-shadow:var(--kb-btn-shadow-hover, none);}<\/style><a class=\"kb-button kt-button button kb-btn1339_ddfcf8-3c kt-btn-size-standard kt-btn-width-type-auto kb-btn-global-fill kt-btn-has-text-true kt-btn-has-svg-false wp-block-kadence-singlebtn\" href=\"https:\/\/www.fzs.unsa.ba\/wp-content\/uploads\/2026\/10\/Spektrofotometrijska-evaluacija-apikalnog-mikrocurenja-kod-upotrebe-tri-razlicita-endodontska-silera-1.pdf\"><span class=\"kt-btn-inner-text\">Download PDF<\/span><\/a><\/div>","protected":false},"excerpt":{"rendered":"<p>Uvod: Projekat predstavlja multidisciplinarnu in vitro studiju istra\u017eiva\u010da sa Stomatolo\u0161kog fakulteta i Fakulteta zdravstvenih studija Univerziteta u Sarajevu u vidu&#8230;<\/p>","protected":false},"author":1,"featured_media":1064,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_kadence_starter_templates_imported_post":false,"_kad_post_transparent":"","_kad_post_title":"","_kad_post_layout":"","_kad_post_sidebar_id":"","_kad_post_content_style":"","_kad_post_vertical_padding":"","_kad_post_feature":"","_kad_post_feature_position":"","_kad_post_header":false,"_kad_post_footer":false,"_kad_post_classname":"","footnotes":""},"categories":[17],"tags":[],"class_list":["post-1339","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-projekti"],"_links":{"self":[{"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/posts\/1339","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/comments?post=1339"}],"version-history":[{"count":1,"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/posts\/1339\/revisions"}],"predecessor-version":[{"id":1341,"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/posts\/1339\/revisions\/1341"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/media\/1064"}],"wp:attachment":[{"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/media?parent=1339"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/categories?post=1339"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fzs.unsa.ba\/en\/wp-json\/wp\/v2\/tags?post=1339"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
