“…Due to complex and not completely accessible morphology apical infiltration is still common in endodontic treatments and thus raises concerns about the quality of the filling provided by the filling materials currently available. The appearance of the spaces and the interface like gaps in the root canal is primarily attributed to the quality of the interface configured by the adhesive endodontic material and dentin, as well as the difficult and unfavorable configuration of the endodontic morphology [7,29,30].…”

“…Air or adhesive materials appear similar in the OCT images, as well as in μCT images. Therefore, the SEM/EDX method was essential to identify that the material defects are voids and their origin [30,36,[40][41][42].…”

“…The analysis made in Figure 10 shows different types of materials that exist in the area where the endodontic material is considered. The preparation of a sample for SEM analysis is one of the most critical aspects of this investigation method [30,43].…”

“…By virtue of non-invasively investigation mode and ability to analyze the profound layers of the material, OCT is a future potential tool for in vivo imaging in dental medicine and endodontics [27,28]. The ef version of OCT proves that real time evaluation of root canal filling adapting to the morphology of the root canal can be made non-invasively in real time [4,5,7,29,30].…”

Objectives: The goal of endodontic therapy is mechanically cleaning and shaping the root canal system, the removal of organic and inorganic debris followed by sealing with permanent filling materials. Materials and Methods: Therefore, the aim of this in vitro study was to engage three imagistic methods: (i) en face (ef) time domain (TD) optical coherence tomography (OCT), (ii) micro-computed tomography (μCT), and (iii) scanning electron microscopy (SEM), in terms of their efficiency in assessing the quality of endodontic fillings. So far, is settled that efOCT images can identify defects/voids in several of the investigated root canal fillings and identify gaps of 50 μm. Results: The results delivered by μCT technology also showed several imperfections of the endodontic filling but also at the interfaces formed by the sealer and the root canal walls. SEM investigations highlights the complex form of the interface formed the endodontic filling material and the walls of the root canal, as well as shortcomings of the materials from several samples. Gaps of 50 μm are identified with efOCT. Conclusions: The net advantage of OCT technology, in respect to the other two technologies consists in its non-invasiveness. The OCT axial resolution is also sufficient to see the material gaps. Another advantage of efOCT investigations is that they allow real-time imaging of complex arrangement at the interfaces of the filling material with dentinal root.

“…[5][6][7][8][9] In endodontics, the use of OCT was described for the evaluation of intracanal anatomy, root perforations, vertical fractures, presence of smear layer on the root canal and analysis of the apical region. 5,[10][11][12] The apical filling consists of an important item of endodontic success, as it could be associated to apical sealing, and control of recontamination. The advent of NiTi instruments associated with single cone (SC) obturation technique, along with the obturation cement, avoids the use of accessory cones commonly used in lateral condensation (LC) technique.…”
