“…This can help, as the same sample can serve as its own control. Studies that have used micro-CT pointed out that dentinal defects are present in uninstrumented roots (Ceyhanli et al 2016;De-Deus et al 2014;Jamleh et al 2015), which is in agreement with recent studies with the root-sectioning methodology. However, as stated earlier, it has been questioned if the scanning resolution offers enough sensitivity (Shemesh 2015) as dentinal defects do not have distinct physical separations in the dentin.…”

“…Jamleh et al eliminated the specimens that presented cracks before instrumentation and detected 90% of specimens instrumented with ProTaper presenting dentinal defects after root canal instrumentation and 50% of the specimens instrumented with WaveOne (Jamleh et al 2015). Similar results were achieved by Ceyhanli et al that also found dentinal defects using micro-CT methodology (Ceyhanli et al 2016). According to that study, 42% of specimens instrumented with ProTaper presented dentinal defects, along with 35% for Safesider and 25% for Race system.…”

“…However, as stated earlier, it has been questioned if the scanning resolution offers enough sensitivity (Shemesh 2015) as dentinal defects do not have distinct physical separations in the dentin. The presence of physical separation is needed for digital signal processing which is why the term microcrack is often used in micro-CT studies (De-Deus et al 2014;Ceyhanli et al 2016). In the science of digital signal processing, the NyquistShannon sampling theorem states that to digitally detect an entity, the signal has to be at least two times larger than the voxel size.…”

Root-originating dentinal defects: methodological aspects and clinical relevance

It was in the 1980s when the association between root-filling procedures and dentinal microcracks was made. Nowadays, root-originating microcracks, also known as dentinal defects, are recognized as a possible precursor that is part of the longitudinal process of root-originating fractures. The presence of dentinal defects has been shown to significantly decrease the outcome through a periapical microsurgery model. Several in vitro articles have been published in the past years in regards to dentinal defects, but most of them have serious methodology concerns that will be discussed in this review. A total grasp of the development and the role dentinal defects play in endodontics is crucial to the specialty. This review aims to discuss dentinal defects and their causative factors and the research models that have been used and their clinical significance. Through a comprehensive critical review of the literature, this article will express the need for further in vivo clinical research and better ex vivo methods that can replicate the clinical setting to answer several remaining questions about the development of and the role dentinal defects play in endodontics.

“…12 Dentinal microcracks can occur during tooth extraction and tooth-sectioning procedures, and pre-existing defects may not be detected using root sectioning and microscopic observation techniques. 13 A crucial goal in endodontic research is to overcome the potential problem of dentinal microcrack formation during instrumentation with rotary or reciprocating instruments. 13 The purpose of this study is to evaluate dentinal defects caused by different NiTi file systems and K files.…”

The aim of the study was to compare different imaging methods in the diagnosis of microcracks on root dentin and to evaluate the frequency of dentinal microcracks observed after root canal preparation using the ProTaper Universal (PTU) system of different sizes. A total of 30 mandibular molars' mesial roots were scanned with microcomputed tomography (micro‐CT) and cone beam computed tomography (CBCT) imaging methods before instrumentation. Root canal instrumentation was performed up to PTU F2 and F4 files. After instrumentation stages, the roots were scanned again with micro‐CT and then with CBCT in same parameters. All roots were sectioned horizontally at 2, 4, 6, 8, and 10 mm from the apices of the specimens. The sections were imaged under a stereomicroscope. Finally, imaging of the sections was done by scanning electron microscopy (SEM). Statistical data analysis of instrumentation steps was performed using Friedman and Wilcoxon tests, and the data of imaging methods were analyzed using Kruskal–Wallis and Mann–Whitney U tests (p = .05). Instrumentation with the PTU system up to F2 and F4 files significantly increased the number of microcracks compared with preoperative samples according to micro‐CT imaging (p < .05). For detecting microcracks on the root dentin, there were no statistically significant differences between micro‐CT (43.9%) and stereomicroscopy (45.8%) (p < .05). SEM showed significantly higher percentage of microcracks (88.3%) (p > .05). No microcrack was observed using the CBCT method. There were no statistically differences between micro‐CT and stereomicroscopy. SEM showed more dentinal microcracks while no microcrack was observed with CBCT.

Comparison of ProTaper, RaCe and Safesider instruments in the induction of dentinal microcracks: a micro‐CT study

Abstract: All instrumentation systems significantly increased the number of microcracks compared with preoperative specimens. The PTU system generated more post-instrumentation dentinal microcracks than the RaCe system.
