The influence of dimethyl sulfoxide on the flow behavior of calcium silicate cement in root canal obturation
Description
This study aims to develop and introduce calcium silicate cement containing DMSO for automated root canal fillings. We hypothesize that DMSO would not alter the flow characteristics of calcium silicate cements. The second hypothesis was that DMSO would not affect the apico-coronal extension of root canal fillings in simulated root canals. The third hypothesis was that DMSO would not affect the microleakage of an extracted human tooth. There are three types of data in the data set. The first data show flow characteristics of calcium silicate cements(CSC and DMSO_CSC) in the gypsum and resin channel. The flow behavior of calcium silicate cement in each channel was observed using a high-speed camera , then filling length was analyzed using the video. The second data show apico-coronal extension of root canal obturation in 8 different types of simulated root canals filled with CSC or DMSO_CSC. The apico-coronal extension was measured and analyzed based on its filling material (CSC or DMSO_CSC), apical size of the canal, taper of the canal, and length of the canal. The third data show nano-scaled leakage of root canal fillings of CSC or DMSO_CSC or control (gutta percha with AH plus sealer).
