To compare the sealing ability of three innovative single‑cone obturation systems. The roots of 90 maxillary incisors were prepared with ProTaper rotary files until reaching to size F4. The roots were divided into four experimental (n = 20 each) and two control groups (n = 5 each). The experimental groups were filled as follows: Group 1, Cold lateral condensation using gutta-percha/ AH Plus Jet; Group 2, Single-cone ProTaper gutta-percha/Guttaflow2; Group 3, Single-cone Propoint PT/Smartpaste; and Group 4, Single-cone Propoint PT/Smartpastebio. The sealing ability of root canal fillings was tested at different time intervals using the glucose leakage model. Glucose leakage values were measured (mg/dL) by a spectrophotometer and statistically analyzed. All experimental groups presented significantly different glucose leakage at all experimental periods (P < 0.05). There was a progressive increase in the glucose leakage during the experimental periods in all groups. During experimental periods, Groups 4 showed the lowest significant cumulative glucose leakage values (P < 0.05).
