Overexpression of miR-10a-5p in LPS-challenged stem cells from the apical papilla resulted in down-regulation of messenger RNA levels of TNFA and up-regulation of interleukin IL10. RNA sequencing of K-562 cells treated withmiR-10a-5pmimics and inhibitors identified miR-10a-5p target genes associated with multiple pathways, including macrophage-mediated inflammation and coagulation pathways. Over 100 miRNAs were differentially expressed in AP and appeared to be involved with modulation of genes in inflammatory and immune pathways. MiR-10a-5p was the most significantly up-regulated miRNA in AP and may play a critical role in suppressing inflammation and promoting healing.

The aim of this study was to evaluate the volumes of total obturation and voids in different obturation techniques using nano-computed tomographic imaging. The null hypothesiswas that the obturation technique and the materials used have no effect on the total volume of obturation or the total volume of voids. Fifty maxillary left central incisor 3-dimensional-printed replicas (TrueTooth; Dental Engineering Laboratories, Santa Barbara, CA) were instrumented and randomly assigned to 5 different obturation groups (n=10) single cone with EndoSequence Gutta-Percha Points (Brasseler USA, Savannah, GA) and Ribbon Sealer (Dentsply Sirona, Tulsa, OK) (SC1), single cone with BC 150 Series Gutta-Percha Points (Brasseler USA) and EndoSequence BC Sealer (Brasseler USA) (SC2), continuous wave with EndoSequence Gutta-Percha Points and Ribbon Sealer (CW), GuttaCorecarrier obturation (Dentsply Sirona) and Ribbon Sealer (GC)
