Abstract

Aim: The purpose of this study was to compare the effects of 20-min applications of MTAD and 15% ethylenediaminetetraacetic acid (EDTA) solutions during final irrigation on the demineralization of root canal dentin.


Methodology: Forty mandibular and maxillary single-rooted teeth were randomly divided into two groups. During initial irrigation following the use of each file, 2 mL of 2.5% sodium hypochloride (NaOCl) solution was applied to all teeth. During final irrigation, 5 mL of EDTA solution was applied to the teeth in Group 1 and 5 mL MTAD solution was applied to the teeth in Group 2. Both solutions were applied for 20 min. All teeth were then washed with 5 mL distilled water and dried with paper points. The teeth were buccolingually bisected along the long axes using hammers and chisels. Scanning electron microscopic (SEM) images were then obtained and scored.


Results: Mann–Whitney U tests revealed significant differences between the MTAD and EDTA groups (p < 0.001).


Conclusions: The EDTA solution produced more demineralized areas in the dentin tubules than the MTAD solution.
