Özet
Objective: It is aimed to compare the effect of root canal treatment and retreatment procedureson the fracture strength of roots. Material and Methods: One hundred and twenty extracted single-canalmandibular premolar teeth were involved in the present study. The bucco-lingual and mesio-distal diameters of the roots were measured. The crowns of teeth were removed from the point of cemento-enamel junction in the way ensuring the standard root length of 14 mm. The teeth were then randomly divided into 6groups (n=20). In Group 1, no instrumentation or obturation was performed. The rest of the roots werechemo-mechanically prepared with nickel-titanium rotary instruments (ProTaper Next, Dentsply Maillefer, Ballaigues, Switzerland) up to size 40/.06. The teeth in Group 2 were left without obturation. Group 3was obturated by using the warm vertical compaction technique. Those in Group 4 were obturated and retreated (20/.07). The teeth in Group 5 were obturated, retreated and apically enlarged (50/.05). Finally, theteeth in Group 6 were obturated, retreated, apically enlarged (50/.05) and re-obturated and then the fracture resistances of the all specimens were tested by using a universal testing machine. Results: There was nostatistically significant difference between the fracture resistance of teeth in Group 1, Group 3, and theGroup 6. No statistically significant difference was found between the teeth in Group 2, Group 4 and Group5. The lowest resistance to fracture was found in Group 5. There were statistically significant differences between Group 1, Group 3, Group 6 and Group 2, Group 4, Group 5. Conclusion: Obturation after preparationand retreatment procedures increased the resistance of teeth to fracture.
