Journal Title: IOSR Journal of Dental and Medical Sciences (IOSR-JDMS) - Year 2019, Vol 18, Issue 4
Abstract
To evaluate the effectiveness of hand files, ProTaper R, Reciproc, XP-Endo Shaper in combination with XP-Endo Finisher R in the removal of obturation material with and without the aid of solvent. 120 extracted human mandibular premolars with single straight oval root canal were selected and prepared with a Reciproc #25.08 to the working length. The teeth were obturated with Elements Free Obturation Unit with AH Plus Sealer and then divided randomly into ten groups (n=10) according to the retreatment techniques. Group 1; hand files, Group 2; Reciproc, Group 3; ProTaper R, Group 4; XP-Endo Shaper, Group 5; XP-Endo Shaper in combination with XP-Endo Finisher R. In Groups 6, 7, 8, 9 and 10 the mechanical retreatment procedures were the same as Groups 1, 2, 3, 4 and 5 respectively. In these groups Resosolv was added to the procedure. The teeth were then split vertically into halves, and the cleanliness of the canal walls was determined by scanning electron microscopy. Statistical analysis were performed using one-way ANOVA, Kruskal–Wallis and Tukey’s honestly significant difference tests (P < 0.05).Reciproc was significantly faster than all the other techniques at removing the filling material from the root canals (p <0.01). XP-Endo Shaper and XP-Endo Finisher R groups were statistically more effective than the other techniques at removing the filling material (p <0.01). All the solvent aided groups were slower than the other groups at root filling removal (p <0.01). Neither retreatment protocols completely removed the filling material from the root canals.
