A Study On The Influence Of Calcium Fluoride Addition To BiodentineTM
Ahmed Hassan El-Banna;
Abstract
The aim of this study was to evaluate the influence of addition of CaF2 powder to Biodentine™ to improve the biological properties without compromising the manipulative and mechanical properties.
Different concentration of CaF2 (2&10 wt. %) was added to the Biodentine™ capsules and compared to a control unmodified Biodentine™. All the experimental groups were characterized using ESEM with EDX and XRD.
The different experimental groups was evaluated regarding their setting time and compressive strength to assess the manipulative and mechanical properties. The cement in-vitro bioactivity was assessed through combined evaluation of ion leaching, pH changes and apatite forming ability over different time intervals (1, 14 and 28 days) after storage in HBSS. Furthermore, the antibacterial effect of the different experimental groups was tested over different time intervals of storage in HBSS.
Regarding the setting time, it was evaluated according to the ISO (6867-2012) for root canal sealer. Both initial and final setting times were evaluated using Gilmore needle. For the compressive strength testing, the cement was evaluated following the ISO (9917-1) for water based cements test method.
Forin-vitro bioactivity, the prepared cements discs were prepared according to the manufacturer’s instructions and stored in HBSS at 37◦ C.
