Tomography in endodontics, an online course on the Hotmart platform, is available, with 8 hours of class duration.
Cone beam tomography is now a reality for planning, treatment and proservation of clinical cases in the endodontic routine. Professionals are increasingly seeking this resource as a support for their work and for a better diagnosis and treatment. Therefore, it is essential to be trained in this resource, which goes far beyond receiving the printed images in the documentation folder.
Applications of tomography in endodontics
The tomography in endodontics has applications in various phases of treatment, from diagnosis to proservation of cases. A tomographic exam is capable of providing more information than the periapical radiograph, and in 30 to 60% of cases, there is a change in diagnosis or professional conduct in relation to that adopted only with the first exam.
CT is useful for the three-dimensional observation of tooth morphology, revealing with much greater fidelity the pulp chamber, with canal floor and entrance, and the number and shape of root canals and useful in detecting additional canals. In addition, teeth with abnormal anatomy can be much better understood with the aid of the exam, in addition to the observation of anomalies and malformations. In retreatments, it is of utmost importance in the detection of untreated canals, a common situation in flattened roots in mesiodistal direction, mentioned above.
Tomography in endodontics can also be used to detect cracked or fractured roots.
In case of root resorption, tomography is a more effective means than intraoral radiographs to locate and size the gaps. Moreover, only a three-dimensional examination can evaluate the communications of the resorptions with the root canal in cases of external resorption or with the periodontal tissues in cases of internal resorption.
Another application of tomography in endodontics, with greater efficiency in the detection of hypodense images in relation to radiographic examination, concerns the observation of periapical lesions, both in diagnosis and in the differential diagnosis between non-endodontic lesions, in surgical planning and in proservation. The tomography reveals images in the periapice earlier, in stages not yet observable in the periapical radiograph and with a higher percentage of detection.
When the hypodense images are located in the upper posterior teeth, the exam can be fundamental in the differential diagnosis of sinusitis of odontogenic origin, by revealing the communication of the lesions with the maxillary sinus, besides cortical disruption and thickening of the adjacent mucosa. This condition is common and underdiagnosed by both dentists and physicians.
One use of tomography, useful both for planning paraendodontic surgery and in preventing accidents in invasive endodontic treatments beyond the apical foramen, in which patency maneuvers and foraminal widening are performed, is the evaluation of the distances between apices and important anatomical structures, such as maxillary sinus and mandibular canal, as well as the observation prior to treatment of apical fenestrations. Therefore, the observation of the latter can also be useful for the diagnosis of long-term postoperative pain with no apparent cause
In dental trauma, tomography is useful to reveal crown and/or root and bone fractures, as well as images of empty alveolar space, typical of injuries involving tooth displacement . Tomography has been shown to be more efficient than panoramic radiographs in the observation of bone and alveolar fractures and than digital periapical radiographs in the detection of horizontal root fractures, even when the modification of the horizontal angulation of the x-rays was not able to reveal the fracture.
In cases of teeth with pulp chamber and root canal blocked by mineralization, a common situation in anterior teeth with a history of trauma, tomography, combined with prototyping technology, can be used through guides made in 3D printers, to guide the access of a surgical drill to the periapical region. Such treatment is called guided endodontic access.
Other applications in which tomography is also useful are the localization of foreign bodies, fractured instruments, perforations, evaluation of gutta-percha cone and/or root filling cement leakage, and in the various fields of endodontic research.
tomography course in endodontics on hotmart platform
The course will qualify the student, dental surgeon or endodontic specialist, to know, indicate and interpret cone beam tomography with endodontic purposes, and is composed of theoretical and practical modules, in which the student will be able to manipulate images in the software.
