Comparison between cone-beam computed tomography and intraoral digital radiography for assessment of tooth root lesions

Objective: This study aimed to assess the knowledge level of Iranian dental practitioners about digital radiography(DR) andcone-beamcomputedtomography (CBCT). Material and Methods: In this crosssectional study, a researcher-designed questionnaire was administered among 180 general dentists and specialists. The questionnaire had three main domains of demographic information, fifteen questions about knowledge of DR (advantages, disadvantages, physical properties) and twenty six questions about knowledge of CBCT (indications, applications, advantages, route of knowledge acquisition). Data were analyzed using descriptive statistics, t-test and Pearson’s correlation coefficient. Results: Of 180 participants, 76 (42.2%) were females. The minimum, maximum and mean± standard deviation scores obtained in DR were 4, 14, and 9.031 ± 1.85 and in CBCT were 0,26 and 18.56 ± 4.81, respectively. In the CBCT domain, the participants had maximum knowledge about “low radiation dose” (72.8%) and minimum knowledge about the “role of CBCT in determination of bone density” (45%). In DR domain, the participants had maximum knowledge about “no need for radiographic films” (75.6%) and minimum knowledge about “not requiring manual processing” (15.6%). Overall, participants had higher level of knowledge about CBCT than DR. An inverse correlation was noted between age and work experience with the number of correct answers. However, no significant difference was noted in the knowledge level of males and females regarding CBCT or DR (p = 0.233 and p = 0.227, respectively). Conclusions: further education seem imperative for dentists in this respect for more efficient diagnosis and treatment planning, minimize patient radiation dose and save time and cost.

Mandibular Second Molar

Endodontic treatments are routinely done with the help of radiographs. However, radiographs represent only a two-dimensional image of an object. Failure to identify aberrant anatomy can lead to endodontic failure. This case report presents the use of three-dimensional imaging with cone beam computed tomography (CBCT) as an adjunct to digital radiography in identification and management of mandibular second molar with three mesial canals.

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

Before And After

The aim of the present study is to compare cone beam computed tomography and periapical digital radiography for the evaluation of root canal preparation. Nine extracted human molars were used in this study. Following access cavity preparation, mesio-buccal roots of maxillary and mesial roots of mandibular molars were prepared and the remaining roots were cut off. Three amalgam cavities were prepared on the coronal part of the teeth and were filled with amalgam to be used as landmarks. Specimens were scanned using cone-beam computed tomography and periapical digital radiograph images were obtained before and after root canal preparation. WaveOne Gold Primary was used for root canal preparation to full working length. Specimens were then scanned using CBCT and a periapical radiograph for the after-instrumentation images. The transportation and centering ratio were measured and calculated on the CBCT and periapical radiographic images. The Bland–Altman method was used for detecting the bias in the evaluation of agreement between the two methods’ measurements. There was agreement between the two methods’ measurements using CBCT scans and periapical digital radiographic images in the evaluation of transportation and centering ratio parameters. The two methods could be used interchangeably in measurements of transportation and calculating the centering ratio.

Objetivo: Describir el uso de las modalidades diagnosticas pertenecientes a la imagenología dentofacial en la odontología forense. Materiales y métodos: Se realizo una búsqueda en la base de datos de PubMed, Google Académico y SciELO con las palabras clave “Dentofacial imaging”, “Panoramic Radiography”, “Lateral Cephalogram”, “Cone Beam Computed Tomography (CBCT)”, “Digital Radiography”, y “Forensic Dentistry”. Se seleccionaron 48 artículos publicados en ingles, de fechas recientes, buscando información que describiera el uso de las modalidades diagnosticas pertenecientes a la imagenología dentofacial en la odontología forense. Resultados: Las modalidades diagnosticas de la imagenología dentofacial incluyen dentro de las más relevantes para la odontología forense la radiografía panorámica, la radiografía lateral de cráneo, la radiografía posterioanterior de cráneo y la tomografía computarizada de haz cónico. Conclusiones: Estas modalidades, junto a la ejecución de análisis morfométricos, permiten al odontólogo forense la identificación de un cadáver, la estimación de la edad, el sexo e incluso la reconstrucción facial forense con fines identificativos.
