Thanks for your precise reading of our article and your constructive comments.We read the letter to the editor, and we should state that you were right on claiming that VRF is usually seen in endodontically treated teeth. But you should consider that the main purpose of this study was to compare the accuracy of two different imaging systems in the detection of VRFs. To my opinion, as the experimentally produced fracture line would be evaluated by the two systems in a same condition, it is not critical to fill the root canals, because the resultant masking effect would be same for both of the systems. Moreover, we used Monagham method in producing VRFs in our study, and if we filled the root canals after inducing VRFs, displacement of fractured parts would be a probable result. The purpose of Kamburoglu study in filling 1/3 apical of root canal is probably to keep streak artifact effect of CBCT images. This artifact is not discussed in two evaluated methods in our study. The reference 2 is probably a compliment to reference 3, and the sampling method was same for both of the articles. We tried to mimic the clinical conditions using Monagham method in producing VRFs, so the fracture lines are at any direction. However, in Kamburoglu study, fracture lines are produced only in a bucco-lingual direction and cannot completely present the clinical conditions. Regarding the fact that aims of reference 1 are the same as ours, it would have been better to discuss it in our study. However, results of this study are in accordance with reference 1, while our sample size was more than three times larger than reference 1.
