The long-term sealing ability of two root canal sealers using different filling techniques

To evaluate the long-term sealing ability of AH Plus (DeTrey, Germany) and RoekoSeal Automix (RSA) (Roeko Dental Products, Germany) when used with different filling techniques. The experiment was conducted on sixty-six extracted single rooted teeth. The crowns were removed at the cementoenamel junction and root canals were instrumented using a step-back technique. Samples were divided into three groups of 20 teeth each and root canals were filled using either cold lateral condesation, the Touch'n Heat technique or the Thermafil technique. For each technique AH Plus was used as the sealer in 10 samples and in 10 samples RSA. Six sample were used as the control group. With the use of a fluid transport model leakage was measured repeatedly at 1 month, 6 and 12 months and recorded in microlitres per day. Leakage was significantly greater (p<0.05) after month 12 compared to month 1, for all techniques and with both sealers. There was no significant difference between sealing ability of AH Plus and RSA. RSA and AH Plus in combination with either cold laterally compacted gutta-percha, Touch'n Heat and Thermafil provided similar sealing ability. Both materials leaked more after 12 months.
