Popis: | Objective: Effective tools and methods are applied during root canal retreatment to eliminate root canal obturation materials and preserve the initial root canal anatomy. The present study compared the efficacy of Reciproc, Neoniti, ProTaper, and Hedstrom files in the retreatment of curved root canals. Material and methods: In the present in vitro study, 100 root canals with 25‒45º curvatures were used. After the samples were initially prepared and examined by CBCT, the root canals were obturated with gutta-percha and randomly assigned to four groups (n=25). A retreatment was carried out in each group with NeoNiTi, ProTaper, Reciproc, and Hedstrom files. CBCT examinations were carried out again under the same conditions. The samples were evaluated at 3-, 6-, and 9-mm distances from the apex on the first and the second CBCT image for root canal transportation and remaining gutta-percha in the root canals. The time required for retreating each canal in each sample was recorded. One-way ANOVA and corresponding non-parametric tests were applied for data analysis. Results: The root canal transportation in the NeoNiTi group was lower than that in the other groups and significantly different from the ProTaper group (P0.05). Conclusion: Despite the fact that the NeoNiTi file produced less transportation than other file systems evaluated in the retreatment of curved root canals, all the files were very effective at the clinically acceptable levels. Svrha rada: Učinkoviti alati i metode primjenjuju se tijekom revizije endodontskog liječenja pri uklanjanju materijala za punjenje korijenskog kanala i kako bi se očuvala njegova početna anatomija. Ovo istraživanje uspoređivalo je učinkovitost instrumenata Reciproc, Neoniti, ProTaper i Hedstrom u reviziji zakrivljenih korijenskih kanala. Materijal i metode: U ovo istraživanje in vitro bilo je uključeno 100 korijenskih kanala sa zakrivljenošću od 25 do 45º. Nakon što su uzorci inicijalno instrumentirani i pregledani CBCT-om, korijenski kanali opturirani su gutaperkom i nasumično raspoređeni u četiri skupine (n = 25). Revizija je provedena u svakoj skupini instrumentima Neoniti, ProTaper, Reciproc i Hedstrom. Ponovno su obavljene CBCT pretrage pod istim uvjetima. Uzorci su procijenjeni na udaljenosti od 3, 6 i 9 mm od apeksa na prvoj i drugoj CBCT snimci s obzirom na transportaciju korijenskog kanala i zaostalu gutaperku u korijenskim kanalima. Zabilježeno je vrijeme potrebno za reviziju svakog kanala u svakom uzorku. Za analizu podataka primijenjeni su jednosmjerna ANOVA i odgovarajući neparametrijski testovi. Rezultati: Transportacija korijenskih kanala u Neoniti skupini bila je manja nego u drugima i statistički se značajno razlikovala od ProTaper skupine (P < 0,05). Nakon revizije zaostala je gutaperka u svim četirima skupinama, što nije bilo statistički značajno (P > 0,05). Zaključak: Unatoč manjoj transportaciji s instrumentima Neoniti u usporedbi s ostalim sustavima procijenjenima u reviziji zakrivljenih korijenskih kanala, svi su instrumenti bili vrlo učinkoviti na klinički prihvatljivim razinama. |
