“…[56][57][58] In retrospective cohorts and case reports, CBCT has been suggested as superior to periapical radiographs in the characterization of periapical lucent lesions, reliably demonstrating lesion proximity to the maxillary sinus, sinus membrane involvement, and lesion location relative to the mandibular canal. [56][57][58] There may also eventually be a role for CBCT in early detection of periapical disease, which could lead to better endodontic treatment outcomes. 55 Promising results have been demonstrated in studies characterizing CBCT images for endodontic surgical planning purposes as well.…”

SUMMARY: Conebeam x-ray CT (CBCT) is being increasingly used for point-of-service head and neck and dentomaxillofacial imaging. This technique provides relatively high isotropic spatial resolution of osseous structures with a reduced radiation dose compared with conventional CT scans. In this second installment in a 2-part review, the clinical applications in the dentomaxillofacial and head and neck regions will be explored, with particular emphasis on diagnostic imaging of the sinuses, temporal bone, and craniofacial structures. Several controversies surrounding the emergence of CBCT technology will also be addressed. C onebeam CT (CBCT) is an advancement in CT imagingthat has begun to emerge as a potentially low-dose crosssectional technique for visualizing bony structures in the head and neck. The physical principles, image quality parameters, and technical limitations relevant to CBCT imaging were discussed in Part 1 of this 2-part series. The second part presented here will highlight the evidence related to CBCT applications in head and neck as well as dentomaxillofacial imaging. Controversial aspects of this technology will also be addressed, including limitations in image quality and its often officebased operational model.CBCT was first adapted for potential clinical use in 1982 at the Mayo Clinic Biodynamics Research Laboratory. 1 Initial interest focused primarily on applications in angiography in which soft-tissue resolution could be sacrificed in favor of high temporal and spatial-resolving capabilities. Since that time, several CBCT systems have been developed for use both in the interventional suite and for general applications in CT angiography. 2,3 Exploration of CBCT technologies for use in radiation therapy guidance began in 1992, 4,5 followed by integration of the first CBCT imaging system into the gantry of a linear accelerator in 1999. 6 The first CBCT system became commercially available for dentomaxillofacial imaging in 2001 (NewTom QR DVT 9000; Quantitative Radiology, Verona, Italy). Comparatively low dosing requirements and a relatively compact design have also led to intense interest in surgical planning and intraoperative CBCT applications, particularly in the head and neck but also in spinal, thoracic, abdominal, and orthopedic procedures. [7][8][9][10][11] Diagnostic applications in CT mammography and head and neck imaging are also under evaluation. 12-14 The technical and clinical considerations pertaining to CBCT imaging in many of these applications have been the subjects of several recent reviews. [15][16][17][18][19] The recent review by Dörfler et al 16 of the neurointerventional applications of CBCT is of particular interest to the field of neuroradiology.The discussion below will focus on the diagnostic and treatment-planning applications of CBCT in dentomaxillofacial and head and neck imaging. Commercially available CBCT systems for dentomaxillofacial imaging include the CB MercuRay and CB Throne (Hitachi Medical, Kashiwi-shi, Chiba-ken, Japan), 3D Accuitomo products (J. Mor...

“…According to several studies, the probability of apical periodontitis existing and not being identified by periapical or panoramic radiography, is considerable [2][3][4] . On the other hand, cone beam computed tomography (CBCT) images are high resolution 1,3,5 , permitting a more precise identification of the apical periodontitis (AP), providing more effective information about the size and location, since the superimposition of the neighboring anatomical structures [1][2][3][4][6][7][8][9][10][11][12][13][14][15] is eliminated.…”

ObjectiveTo perform a descriptive study in order to evaluate apical periodontitis in endodontically treated teeth using cone beam computed tomography. Methods Eighty RESUMO ObjetivoRealizar um estudo descritivo para avaliar periodontites periapicais em dentes com tratamento endodôntico em tomografia computadorizada de feixe cônico. MétodosOitenta e seis exames que apresentaram pelo menos uma periodontite periapical foram selecionados e separados em dois grupos: 1 para a mandíbula, e 2 para a maxila. Todos os exames foram realizados na tomografia computadorizada de feixe cônico com os mesmos protocolos de aquisição, e o mesmo software de avaliação e de mensuração. As lesões foram classificadas de acordo com o índice periapical, mas sem considerar a expansão do osso cortical e/ou destruição. ResultadosCento e vinte sete dentes inferiores e 180 dentes superiores apresentaram periodontites periapicais com tamanho médio de 0,49 mm na mandíbula e de 0,75 mm na maxila. Observou-se que os pré-molares inferiores foram os dentes mais acometidos. Lesões identificadas entre os escores 0 e 1 corresponderam a 83,47% das lesões na mandíbula e 78,89% na maxila, sendo que 55,12% dos dentes tratados endodonticamente inferiores e 50% superiores não apresentaram lesões reincidentes ou em fase de reparação. ConclusãoHouve um predomínio de periodontites periapicais pequenas, sendo os pré-molares os dentes mais acometidos por estas lesões.Termos de indexação: Periodontite periapical. Tomografia computadorizada de feixe cônico. Diagnóstico por imagem. Tecido periapical.

“…O exame radiográfico, além de ser pobre em detalhes, não apresenta condições de medida do diâmetro dos canais radiculares, uma vez que se trata de uma imagem gerada em dois planos de uma estrutura com aspecto tridimensional. (EDER, et al, 2005;ESTRELA et al, 2008a;LOW et al, 2008;PAULA-SILVA et al, 2009). …”

“…(BERGMANS et al, 2001) Apesar deste avanço tecnológico, sua baixa difusão e utilização na comunidade odontológica foram determinadas por vários fatores limitantes tais como: altas doses de radiação para o paciente; baixa resolução das imagens para as exigências odontológicas; tamanho amplo do equipamento e a obrigatoriedade do paciente permanecer deitado para a realização do exame (LOW et al, 2008 (METZGER et al, 2010).…”
