Abstract
Abstract
Background: Since there are significant differences between instruments and guta-percha cones of the same size, cutting and adapting the guta-percha cone to the desired size is very important for apical sealing. The aim of this study was to evaluate the accuracy of the cut lengths of guta-percha cones cut with a scalpel blade under different magnifications using stereomicroscope-based measurements.
Materials and Methods: The tips of the gutta-percha cones were cut 2 mm with the naked eye ve under different magnifications using a scalpel blade and stainless steel endodontic finger ruler. The use magnifications were 2.5x Galilean loupe (Keeler, Windsor, UK), a 7.5x prismatic loupe (Admetec, Haifa, Israel) and a 25x operating microscope (Zeiss, Oberkochen, Germany). Each cut guta-percha tip was imaged under a 40x Zeiss Stemi 305 stereomicroscope using Zeiss Zen Lite 2 software and lengths were measured by two observers. Inter-observer agreements were calculated utilising the weighted kappa coefficient. Data were analyzed by Kruskal Wallis H test at P<0.05 significance level.
Results: There was no statistically significant difference between cut-lengths of gutta-percha cones depending on the magnification (p>0.05). Although there was no statistically significant difference, the mean values of the 25x magnification group were lower than the other groups (26,03).
Conclusions: Given the limitations of this study, similar guta-percha cut lengths were obtained under the naked eye, 2.5x, 7.5x and 25x magnifications. In order to better evaluate the magnification efficiency, studies with larger sample sizes, along with evaluating the morphological surface, are needed.
