Calcium Release and pH of Three Endodontic Root Canal Sealers
ثبت نشده
چکیده
The aim of this study was to asses the calcium release and pH of three root canal sealers. pH and calcium release of three root canal sealers Apexit, Sealapex and Vitapex, were assessed at 30 and 60 min, and 7 days after spatulation. After manipulation, the sealers were placed in tubes and immersed in sealed glass flasks containing 10ml of deionized water and stored at 37°C. Tubes were removed at the scheduled times and the water was tested for pH with a potentiometer and for released calcium atomic absorption spectrophotometry was used. Vitapex produced an alkaline pH and released significantly higher calcium amounts more pronounced results at 7 days compared with the other sealers. Sealapex presented the highest calcium ion release, especially after the longest interval. High calcium release and pH are valuable features for a root canal sealer under clinical conditions.
