Summary. The quality of the apical seal using the single cone gutta‐percha obturation technique with four different dentinal bonding agents was assessed by measuring the linear penetration of methylene blue dye. No leakage was measurable in 75 per cent of the canals sealed with Scotchbond, 70 per cent of canals sealed with Restodent, 60 per cent of canals sealed with Dentin‐Adhesit, and in 30 per cent of canals sealed with GLUMA. The mean linear dye penetration in canals sealed with these agents was 0.32, 1.95, 0.57 and 2.41mm, respectively. There was no statistically significant difference between the single cone gutta‐percha technique and the laterally condensed gutta‐percha technique when Scotchbond was used as sealer (P > 0.01).
