E. Faecalis Prevalence in Primary and Secondary Endodontic Infections: a Pre-post Microbial Analysis Following Chemo-mechanical Preparation

Chemo-mechanical preparation will be performed using reciprocating instruments . Irrigation will be carried out with 5.25% NaOCl during instrumentation and a final flush of 17% EDTA followed by 5.25% NaOCl. After drying with paper points, canal obturation will be achieved through continuous condensation wave technique. Obturation with gutta-percha will be performed using Reciproc blue R25 master cones and root canal sealer using the BeeFill 2 in 1 device (VDW, GmbH) with a small heat carrier (#40 tip size and .03 taper) following the manufacturer's instructions. After the down-packing phase, the back-filling will be performed with the same device and manual compaction using endodontic pluggers.
