Sažetak
Uvod/Cilj Primena instrumenata od legure nikl-titanijum (NiTi) u čišćenju i oblikovanju kanala je standard i preduslov za uspeh endodontskog tretmana. Cilj ovog rada je bio da se analizom skenirajućim elektronskim mikroskopom (SEM) proveri efikasnost čišćenja apikalne trećine kanala primenom dva različita NiTi sistema sa recipročnim pokretima. Metode U istraživanje je uključeno 20 jednokorenih zuba (pretkutnjaka) podeljenih u dve grupe. Preparacija kanala u prvoj grupi je realizovana jednom turpijom sa recipročnim pokretima UNICONE (MEDIN, Nove Mjesto u Moravskoj, Češka), a u drugoj instrumentom sa recipročnim pokretima RECIPROC BLUE (VDW Gmbh, Minhen, Nemačka). Kao rastvori za irigaciju korišćene su iste količine 2% rastvora NaOCl i 17% rastvor EDTA. Uzorci pripremljeni za analizu SEM razmaznog sloja u apikalnoj trećini su evoluirani prema skali 1-5 i na uveličanju od 1000×. Rezultati Analiza SEM je ukazala na uglavnom čiste zidove kanala u apeksnom segmentu u obe testirane grupe. Nešto čistiji zidovi uočeni su posle primene turpije UNICON (78%) u odnosu na uzorke druge grupe, gde je instrumentacija realizovana turpijom RECIPROC BLUE (76%), ali bez statistički značajnih razlika. Zaključak Recipročni sistemi sa jednom turpijom ne uklanjaju potpuno razmazni sloj, ali obezbeđuju efikasno čišćenje apikalne regije kanala.
