“…Regarding dental fractures, MRI has the potential to help in determining the presence and extent of cracks and fractures in teeth due to good contrast, and especially without exposure to ionizing radiation as with CBCT, which is considered the current clinical standard [ 34 ].…”

“…In most cases, discontinuities cannot be definitively visualized in the absence of invasive measures such as CBCT imaging; in the study of Schuurmans et al, the aim was to develop MRI criteria for the identification of root cracks and fractures and to establish reliability and accuracy in their subsequent detection [ 5 , 34 ].…”

“…A problem when evaluating these MRI studies is that in vitro sequences are frequently applied, with very long acquisition times, and they are impossible to be applied in vivo, and therefore are far from improving clinical practice. From the results of these studies, it is possible to highlight that MRI, thanks to the higher contrast, has allowed for better evaluation of cracks and fractures compared to CBCT imaging [ 34 ].…”

An Update of the Possible Applications of Magnetic Resonance Imaging (MRI) in Dentistry: A Literature Review

This narrative review aims to evaluate the current evidence for the application of magnetic resonance imaging (MRI), a radiation-free diagnostic exam, in some fields of dentistry. Background: Radiographic imaging plays a significant role in current first and second level dental diagnostics and treatment planning. However, the main disadvantage is the high exposure to ionizing radiation for patients. Methods: A search for articles on dental MRI was performed using the PubMed electronic database, and 37 studies were included. Only some articles about endodontics, conservative dentistry, implantology, and oral and craniofacial surgery that best represented the aim of this study were selected. Results: All the included articles showed that MRI can obtain well-defined images, which can be applied in operative dentistry. Conclusions: This review highlights the potential of MRI for diagnosis in dental clinical practice, without the risk of biological damage from continuous ionizing radiation exposure.

“…As discussed, the diagnosis and localisation of cracks in teeth can be challenging; recently, a number of imaging techniques have shown some promise in visualising these. Firstly, imaging of teeth ex vivo with magnetic resonance imaging (MRI) using a protocol called sweep imaging with Fourier transformation (SWIFT) and a custom intra-oral MRI coil demonstrates cracks as small as 20 µm, and images are not hampered by streak artefact from metallic restorations as seen when using cone beam computed tomography (CBCT) 82,83 ; additionally, MRI avoids using ionising radiation and the problems that may come with this. This is important because MRI using conventional clinical protocols is typically unable to obtain useful signal from dental hard tissues, although currently the SWIFT protocol is not available on most MRI systems.…”

The painful tooth: mechanisms, presentation and differential diagnosis of odontogenic pain

2020

Pain arising for the teeth and supporting structures is a very common complaint, affecting around 9% of adults in the UK, and it can sometimes be difficult to determine the exact cause. In this narrative review, we explore the underlying neurophysiology of odontogenic pain and describe the relevance of this to clinical practise. We discuss characteristic features of pain arising from the various dentoalveolar structures and common oral disorders, and consider that nonodontogenic pain may occasionally present as toothache. As well as describing current approaches to reaching a reliable diagnosis, we also discuss some innovative techniques and potential future developments in this area.

“…Several methods have been used for diagnosing tooth cracks, such as methylene blue dye, microscopic examination, transillumination, the bite test, periapical radiography (PR), cone-beam computed tomographic (CBCT) imaging and magnetic resonance imaging (4,5). PR cannot diagnose early tooth cracks, especially when the crack extends from mesial to distal, or the crack is parallel to the long axis of the tooth.…”

Introduction The aim of this study was to evaluate four different ways in diagnosing tooth cracks, which may provide certain theoretical bases for early diagnosis of cracks. Methods 123 freshly extracted human teeth were collected in the Stomatology Hospital of Guangzhou Medical University, Guangzhou, China. Three observers examined the cracks of the crowns with naked eye, microscope, methylene blue dye, and methylene blue dye with magnification microscopic examination methods independently. Two criteria (crack lines appeared in enamel and dentin) were used to diagnose teeth cracks, and statistical analysis was performed using the SPSS and MedCalc statistical software. Kendall's W was conducted to assess the agreement among the three observers in each detection method. Sensitivity, specificity, positive predictive value, negative predictive value, and the area under the curve (AUC) drawn in terms of sensitivity and (1-specificity) were calculated to evaluate the diagnostic value of four different methods. Results 3 teeth were excluded because of the visual fatigue of the observer, and there were 120 teeth left. The method of methylene blue plus microscope had the lowest value of Kendall's W in criterion 1 and 2. The overall AUC values were more than 0.7 in both the microscopic and methylene blue plus microscopic method according to criterion 1 and 2, and in the method of naked-eye according to criterion 2. The pairwise comparison between A, B and C had statistical difference in the method of naked-eye, microscope and methylene blue plus microscope in criterion 2 ( P < 0.05). Conclusions Detecting tooth crack with the method of methylene blue plus microscope have a higher consistency among different experienced endodontists. Microscope and methylene blue dye with magnification microscopic examination were effective methods to diagnosis tooth crack. More cracks can be detected by experienced endodontists, and the difference persisted even with the use of microscopes or methylene blue dye.
