Self-adjusting file (SAF) compared to newly designed rotary and reciprocating files: composition and microstructure, microbial biofilm removal capability and shaping effectiveness

Abstract

The aim of this study is to compare the Self adjusting file (SAF) to Wave One (WO) , BT-Race (BTR) and manual instrumentation (MAN) in their basic composition through SEM-EDX spetroscopy, the ability in disinfecting ex vivo long oval canals after E.Faecalis contamination though cultures and the cleanliness of the root canal space for debris and smear layer through SEM and Optical microscopy after chemomechanical preparation.Files were analysed through SEM-EDX spectroscopy for the basic composition. All files analysed contained Ni and Ti. The WO contained 52,14%wt. of Ni and 46,79%wt. of Ti, the SAF 51,99%wt. of Ni and 47,12 %wt. Ti and the BTR 51,49%wt. of Ni and 47,31%wt. of Ti. No differences were observed between the groups. For the microbiological experiment 100 long oval teeth were collected and after initial preparation and contamination with E.Faecalis were divided into four groups randomly (n=25). Before chemomechanical preparation the first microbiological sampling was perform ...
