Of course, the shaping quality goes hand in hand with the cleaning quality, because as long as cleaning is carried out, irrigants can penetrate and clean canal walls. Unless we are dealing with native structural imperfections (creep fracture), first of all, we have to take into account the accumulation of cyclic fatigue to which the instruments are subject, and the torsional stress produced during cutting maneuvers. In this article, we are going to describe the innovation brought to product research, regarding Ni-Ti instruments.Дealing with instruments and instrumentation, the most worrying issue is the risk of fracture to which they are subject. However, there are still doubts about their efficacy, especially if we take into account the cost-benefit ratio.ДЄs for As for new sealers (bioceramics), please refer to a further article that will deal with their characteristics and instructions for use. Irrigation and its issues associated with the various devices on the market were mentioned in a previous article on this blogВ and (but), to date, there has been no further innovation, except for some studies on laser-assisted techniques (PIPS). Instrumented Areas in Yellow вЂ“ Non-instrumented Areas in RedД¬linical and product research has focused on problem solving by concentrating work in three direction Only by removing the canal content (whether organic or not) irrigants are able to carry out their action, allowing the sealer and the filling materials to seal the endodont.ДЇor this purpose, different instrumentation methods have been developed over the years, making use of higher and higher performance materials however, studies carried out so far, by using Micro-Ct, have shown that an endodontic area, up to 70%, depending on the root canal anatomy and the root canal section examined, is left untreated, i.e. The need to shape a root canal root canal thoroughly is surely the primary purpose of any proper endodontic treatment.
