Root canal filling is the most important stage in root canal treatment (RCT). Leakage at ⅓ of the tooth root can be affected by the type of cement, leading to RCT failure. This study analyzed leakage at the filling stage using calcium hydroxide (CaOH)2 and zinc oxide eugenol (ZOE) cements. The experimental laboratory study used samples of 16 maxillary central incisor teeth prepared by conventional techniques, divided into two groups and RCT was performed using the single cone technique. The samples were immersed in india ink for 7x24 hours, decalcified until transparent. The ink penetration depth was evaluated by stereo microscopy. As a result, the Ca(OH)2 cement group had 7 samples with a score of 1 and 1 sample with a score of 2. In the ZOE group, there were 5 samples with a score of 5 and 3 samples with a score of 3. The data were analyzed with an inde-pendent t-test to determine the differences between treatments (p<0.013). It was concluded that there was a significant differ-ence between the two cements, namely Ca(OH)2 cement showed better sealing ability than ZOE.
