Addition of MTA in a salicylate-based resin root canal sealer to retrograde root-end filling

Aim To evaluate the flow, pH and calcium release of white MTA (WMTA), salicylate-based resin root canal sealer (Sealapex; SEAL) SEAL containing 10 (SE10) or 20% (SE20) (w/w) MTA. Methodology Flow test was realized according to ISO 6876 specification. The sealers samples (n= 10) were placed in polyethylene tubes immersed deionized water. After 24 hours 7, 14, 28 days, water determined with a meter, assessed by atomic absorption spectrophotometry. Results WMTA showed respectively highest lowest flow rate when compared other materials (P<0.05). SE20 value only 24h 7 days periods (p<0.05). In 14- 28-days periods, (p<0.05), but there are no differences between groups (p>0.05). all Conclusions proves be an association better handling than WMTA, satisfactory potential for alkalinization release.
