Root Fractures

Detecting vertical root fractures represents an immense challenge for oral health professionals. One of the main tools used to detect this type of biological complication is the periapical radiograph. However, conventional radiography consists of two-dimensional imaging that is limited by the superimposition of bony structures that complicate the detection of root fractures. The alternative, a Cone-Beam Computed Tomography (CBCT) scan, cannot be prescribed in every case since radiation should be kept to a minimum as stipulated by the “As Low As Reasonably Achievable” (ALARA) principle. Therefore, to justify the use of a CBCT scan to detect a vertical tooth root fracture, the clinician must prove that it has significant benefits over traditional imaging. Since few systematic reviews have compared CBCT technology to traditional radiography for the diagnosis of vertical root fractures, it is of utmost importance in clinical practice, especially in endodontology and clinical dental medicine, where the available reviews are examined to generate a clinical recommendation. The four hypotheses of this protocol are that (1) CBCT is superior to traditional radiography for detecting vertical root fractures of vital teeth; (2) CBCT is superior to traditional radiography for detecting longitudinal root fractures of vital teeth with radiopaque restorations; (3) CBCT is superior to traditional radiography for detecting vertical root fractures of root-filled teeth without a radiopaque post that may cause artifacts; and (4) CBCT is superior to traditional radiography for detecting vertical root fractures of root-filled teeth with a radiopaque post regardless of its longitude. To test these hypotheses, all the current secondary resources related to the aim of this meta-review are evaluated. If there is sufficient evidence to support clinical decisions, then the appropriate recommendations will be formulated. PROSPERO ID: CRD42018067792

ABSTRACT Aim Our objective was to perform an in vitro evaluation of root fracture in endodontically treated teeth using two cone beam computed tomography (CBCT) machines. Materials and methods The sample comprised 86 singlerooted human premolars that had been fractured by a universal testing machine. The tomographic images were acquired using an Orthopantomograph OP300® and an Orthophos XG 3D® and evaluated by three examiners, by means of specific software. The teeth were classified into presence or absence of root fracture, then the root third where the fracture occurred, was determined. With regard to the detection of the fracture, the Kappa statistic was used for intra and interexaminer reproducibility at two distinct points in time. Chi-squared test was employed to analyze the sensitivity and specificity of the two tomographs (p < 0.05). Results The results showed a good or excellent Kappa index between examiners. As for the absolute frequency, the sensitivity (0.6) of the Orthophos XG 3D® equipment was superior, while specificity (0.91) was higher with the Orthopantomograph OP300®. On the receiver operating characteristics curve, moderate performance was found with an accuracy of 0.73 (OrthopantomographOP300®) and 0.74 (Orthophos XG 3D®) respectively. As far as the location of the root fracture is concerned, moderate agreement was verified using the Kappa statistic (k = 0.56). Conclusion Although the regular CBCTs represent the imaging examination of choice for assisting root fracture diagnosis in endodontically treated teeth, their performance in this study demonstrated an imprecise diagnosis of fractures in a good many cases, irrespective of the tomography machine used. Clinical significance An early and precise detection of root fractures is of the utmost clinical importance, but the radiopaque and/or metallic filling materials in the CBCT viewing field may generate artifacts, known as the beam-hardening effect, which could compromise root fracture detection.

Horizontal Root Fracture

Different locations and healing patterns of horizontal root fractures bear different prognoses. Conventional periapical radiographs have been routinely used for the evaluation of the locations and healing of horizontal root fractures, with the limitation of presenting two-dimensional images. The three-dimensional imaging technology, cone-beam computed tomography (CBCT), has recently gained interest in dental traumatology, in particular for locating and diagnosing root fractures. However, the assessment of healing patterns of horizontal root fracture using CBCT compared to conventional radiographs has not been established. This case report describes the different healing patterns evaluated by two-dimensional radiographs and CBCT of a horizontally root-fractured maxillary right central incisor treated with mineral trioxide aggregate (MTA) with a two-year follow-up. The findings suggest that the healing patterns of horizontal root fractures seen on conventional radiographs and CBCT may be different.

Abstract Background Endodontic disease can adversely affect the quality of life and therefore early diagnosis and consequent timely treatment is of paramount importance for the Endodontist. Radiology is an essential component in treatment planning, disease monitoring and assessment of treatment outcome. Periapical radiographs and panoramic radiography are frequently utilised but they provide only two-dimensional representation of three-dimensional structures. The advent of cone beam computed tomography (CBCT) offers three-dimensional accuracy of the hard tissue images with a reasonable cost and this has revolutionised imaging of the dentomaxillofacial structures. This imaging system has been seen to overcome some limitations of conventional radiography, as brought out in this review. The improvement in the accuracy is, however, accompanied at the cost of increased radiation exposure to the patient. Nevertheless, smaller areas of exposure are normally appropriate for endodontic imaging, and adjustment in the exposure parameters can further moderate the effective dose (Loubele et al. 37(6):309-18, 2008). Aims and objectives The aim of this review is to present the pertinent literature on the various applications of cone beam computed tomography in the field of endodontics. Methods Literature was electronically searched on the following sources; Medline and Keats Library. Further, a manual search was performed on the following journals: International Endodontic Journal, Journal of Endodontics, Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, Endodontology, Journal of Dental Research, European Journal of Oral Sciences & Odontology and Dentomaxillofacial Radiology. A preliminary search was performed to gain an idea of the available literature using keywords ‘Cone Beam Computed Tomography’ to view the volume of the literature evident and identify questions to be addressed in this review. The initial search showed 243 potential articles. After scrutinising the titles and abstracts of the retrieved articles, 70 relevant studies were reviewed in full text. Furthermore, ‘published guidelines on the use of CBCT’ were also searched so as to include the results as an additional source material. All the articles eligible to be included in the review were in the English language and ranged from the year 1960 to the present. Also all the studies reviewed were based on the various uses of cone beam computed tomography in the field of endodontics. The keywords used to search were ‘Cone Beam Computed Tomography (CBCT)’, ‘Conventional radiography’, ‘Applications of CBCT in endodontics’, ‘CBCT and tooth morphology’, ‘CBCT and apical periodontitis’, ‘CBCT and vertical root fractures’, ‘CBCT and resorption’, ‘CBCT and pre-surgical assessment’, ‘CBCT and dento-alveolar trauma’ and ‘CBCT and endodontic outcome’. Results Every case is unique and CBCT should be considered only after studying each case individually. CBCT imaging needs to be adopted or used where information from conventional imaging systems is either inadequate for the management of endodontic problems or inconclusive. Having said that, it is safe to state that CBCT imaging has the potential to become the first choice for endodontic treatment planning and outcome assessment, especially when new scanners with lower radiation doses and enhanced resolution would be available.
