Effect of three fiber post removal technique on the amount of root dentin an in vitro study

Aim: Aim of the current research was to differentiate among three distinct methods for removing fiber posts and assess their influence on the quantity of preserved root dentin. Methods: For 30 removed single-rooted teeth, the teeth were decorated along with endodontic treatment was performed. The roots were cut apically at (11mm from the CEJ) and fibre post spaces were made. Stereomicroscope radiographs of the apical cross section during post space were taken at 20x magnification. Dual cure resin cement was used to secure the fibre post. Following specimen were illustrated in the three (n=10) groups using the fibre post eliminated method: Diamond bur (I), Pesso reamer (II), and Ultrasonic tips (III). The previous section's photographs were shot at the same magnification after the post was removed. Graticule was utilized for assessing the x and y axis space disparities among prior to and following removing photographs. The one-way ANOVA test with the Bonferroni adjustment was used to statistically analyse the data. Results: The mean amount of root dentin eliminated was highest in diamond bur group when measured on x axis and y axis, while it is lowest for ultrasonic tip at both the axis. Conclusion: The most forceful approach for removing glass fibre was the diamond bur group.
