“…Micro CT is recognized as the gold standard for the morphological evaluation of the effects of canal shaping. This method is important, as it can be used in in vitro studies to improve the distribution in the study sample, using established morphological parameters to provide a consistent baseline [41]. For example, it is possible to select radicular systems with similar morphologies to eliminate potential anatomical bias that would alter the research results, using established morphological parameters to provide a consistent baseline [42].…”

Endodontic shaping can lead to canal and apical anatomical alterations, which may compromise the outcome of root canal treatment. The objective of this systematic literature review is to assess whether the use of martensitic endodontic instruments can result in less apical transportation compared to austenitic instruments during endodontic therapy. A search was conducted on PubMed, Ovid MEDLINE, and the Web of Science. The inclusion criteria were in vitro studies comparing apical transportation using endodontic instruments with austenitic or martensitic alloys. The search of the scientific databases yielded 592 results, of which only 10 were eligible for evaluation after screening. Based on the analysis of the selected articles, it can be concluded that martensitic endodontic instruments result in less apical transportation compared to austenitic instruments during the shaping phase of endodontic treatment. This behavior can be attributed to the increased flexibility of martensitic instruments. Further research is warranted to further explore this topic and provide additional evidence supporting the use of martensitic instruments in clinical practice.

“…The NiTi alloys used in endodontic instruments contain approximately 56% by weight of nickel and 44% of titanium, in an equiatomic ratio of 1:1 [41]. In some nickel-titanium alloys, 2% of the nickel is converted to cobalt [43].…”

“…Cesaitiene et al assessed the canal transportation and centering ability of different techniques of glide path preparation by the use of rotary files in curved root canals. They demonstrated that all rotary systems had a similar performance in this respect [ 25 ]. They used PathFile and ProGlider files in their study, which are different from the file systems used in the present study.…”

Aims. A glide path is created prior to root canal instrumentation by nickel-titanium (NiTi) rotary files to increase the efficiency and safety of cleaning and shaping. This study aimed to assess root canal transportation in use of different glide path files in curved canals. Materials and Methods. 30 sound mesiobuccal root canals of mandibular molars with 20° to 40° curvature were selected and randomly assigned to 3 groups of EdgeGlidePath (EGP, EdgeEndo), One-G (Micro-Mega), and Neolix (Neoniti). The specimens were scanned before and after glide path creation by microcomputed tomography (micro-CT). The pre- and postoperative micro-CT scans were superimposed, and the degree of canal transportation and centering ratio were measured at 1, 3, 5, and 7 mm distances from the apical foramen. Statistical Analysis. The data were analyzed by two-way and one-way ANOVA. Results. The effects of distance from the apical foramen and instrument type and the interaction effect of the two were not significant on the centering ability of the files or canal transportation. Conclusion. EdgeGlidePath, One-G, and Neolix files fabricated from the conventional NiTi alloy or heat-treated M-Wire alloy showed similar performance regarding centering ability and canal transportation in glide path preparation in curved canals.

The introduction of nickel–titanium rotary instruments revolutionized shaping procedures as they were able to produce a well-tapered preparation while reducing operator fatigue. The major drawback of rotary instruments was the high risk of fracture due to bending and torsional stress. Thus, the creation of a glide path has been advocated and recommended by most rotary instrument manufacturers. The aim of the present review is to summarize existing knowledge on glide path preparation and identify areas where further research is needed. The primary goal is to provide a comprehensive overview of the techniques and instruments used in glide path preparation, highlighting their advantages and limitations. The secondary goal is to explore the effect of glide path creation on the overall success of endodontic treatment, particularly in terms of reducing procedural errors and improving treatment outcomes. An online search on PubMed, ScienceDirect, UCLA, and Scopus databases was conducted, and 116 articles were identified. Eligible articles were divided into nine categories based on what they researched and compared. The categories included centering ability and/or root canal transportation, cyclic fatigue resistance, glide path and shaping time, tortional stress resistance, apical extrusion of debris and/or bacteria, defects in dentine walls, file separation, postoperative pain assessment, and scouting ability and performance. Establishing a glide path reduces root canal transportation, especially with rotary methods. Reciprocating and heat-treated files offer higher fatigue resistance and shorter preparation time. Instruments with shorter pitch lengths have greater torsional strength. Preparation and coronal preflaring reduce apical debris and bacteria. Glide paths do not affect dentine microcracks, file separation, or defects but reduce immediate postoperative pain and improve cutting ability. Randomized trials are needed to assess their impact on treatment outcomes.
