Abstract
Objective: To compare the sealing ability of three single-cone obturation systems using a glucose leakage model. Materials and Methods: A total of 90 freshly extracted human mandibular incisors with oval canals were selected and their crowns were cut. The ischolar_main canal of each sample was instrumented using a rotary crown down technique and then divided into four experimental (n=20 each) and two control groups (n=5 each). Samples in the experimental groups were filled as follows: Group 1, cold lateral condensation using Gutta-percha/AH Plus; Group 2, single-cone C-Points/Smart-Paste Bio Sealer; Group 3, single cone Bio-Ceramic Impregnated Gutta-Percha/Endo-Sequence Bio-Ceramic Sealer; Group 4, single-cone Resilon/RealSeal SE. After 7 days, the sealing ability of ischolar_main canal fillings was tested at different time intervals using glucose leakage model. Glucose leakage values were measured using a spectrophotometer and statistically analyzed. Results: The four experimental groups presented significantly different glucose leakage values at all test periods (P<0.05). At the end of the observation period, the cumulative glucose leakage values of Groups 2 and 3 were significantly lower than those of Groups 1 and 4 (P<0.05). Conclusion: C-Points/ Smart-Paste Bio and Bio-Ceramic Impregnated Gutta-Percha/Endo-Sequence Bio-Ceramic Sealer combinations provided the superior sealing ability over the lateral condensation technique.
