Sažetak
Uvod Cilj ovog rada je bio da se primenom skenirajuće elektronske mikroskopije analiziraju površine novih ručnih endodontskih instrumenata i proveri eventualno postojanje proizvodnih nečistoća ili defekata na radnom delu. Materijal i metod U istraživanju su korišćena po tri seta novih ručnih instrumenata: K-File (KF), (18 instrumenata) (Dentsply Maillefer, Switzerland) i Hedstorm Files (HF), (18 instrumenata) (SybronEndo Co, USA). Instrumenti su podvrgnuti SEM analizi sa uvećanjem 170×, a semikvantitativnom EDXS analizom utvrđivan je hemijski sastav nečistoće. Statistička analiza je urađena primenom Fišerovog testa (p < 0,05). Rezultati Rezultati su pokazali da ne postoji nijedan instrument bez defekta. Najučestaliji tip defekta je bilo prisustvo metalnih opiljaka i žlebova, koji su uočeni na površini svih ispitivanih instrumenata. Debri je uočen na svim KF (100% apikalno i u srednjoj trećini) i HF (56% apikalno i 56% u srednjoj trećini). Prisustvo udubljenja zabeleženo je kod KF (33% apikalno i 39% u srednjoj trećini) i HF (11% apikalno i 6% u srednjoj trećini). Korozija radne površine, pojava uglačane površine i prekid sečivne ivice su uočeni samo u grupi KF. Zaključak Na svim ispitivanim ručnim instrumentima su uočeni proizvodni defekti, a najučestaliji tip nepravilnosti je bilo prisustvo metalnih opiljaka i žlebova.
