“…The quick improvement of innovation has brought forth different advanced dental imaging modalities, including digital intraoral radiography and cone beam computerized tomography (CBCT) scanners. CBCT has made storming in maxillofacial imaging, encouraging the progress of dental determination from 2D to 3D pictures and extending the part of imaging from finding to imaging guidance of operative and surgical systems by utilization of outsider programming [2][3][4][5][6][7][8][9][10][11].…”

To ensure the diagnostic ability of CBCT for caries detection under different types of tooth colored restorative materials. Material and Methods: In the present study a total of 80 extracted carious permanent molar teeth were selected. Caries was classified as grade 3 according to International Caries Detection and Assessment System (ICDAS) criteria. Half of carious lesions were removed from 40 molars as Control specimens. Carious teeth were randomly assigned into two groups and each group was divided into four subgroups including: two carious and two non-carious as controlled group and all the teeth were filled with different bioactive restorative materials, then all the specimens were scanned with cone beam computed tomography (CBCT) using a Promax ® 3DMid CBCT device (Planmeca, Oy, Helsinki, Finland). Results: Caries was detected in all the carious specimens of all the groups except that group A2 was much less remarkable than other groups. In the control specimens (noncarious) of all the groups: No caries was detected .Conclusion: Although CBCT is an excellent tool for secondary caries detection under different types of restorative materials but it should not be used as a primary diagnostic tool on regular basis. If its use is a must, so, optimized low dose low resolution protocol is recommended.

“…It is better than a medical CT because it gives 3D tomographic images while subjecting the patient to less radiation. While it is useful in cases where 2D imaging techniques are inadequate, it nevertheless uses more radiation than 2D radiographic imaging techniques, so the technician has to exercise care when using this method [18].…”

Dental Caries - Diagnosis, Prevention and Management

View full text Add to dashboard Cite

When preparing prosthetic restorations, dentists always try to create restorations functionally ideal while not compromising on esthetics. The factors that make a restoration successful include how well they fit both internally and marginally, their ability to withstand punishment without breaking, and their visual appeal. Imperfect marginal adaptation can lead to unpleasant and unwanted side effects such as plaque accumulation, marginal discoloration, microleakage, carious and endodontic lesions, and periodontal disease. If there is a gap between the crown and the prepared tooth, this can result in the dissolution of the luting material. If the fit of the restoration and the thickness of the cement are designed to be favorable, the cement is not dissolved and the abutment tooth is prevented from secondary caries. The marginal fit of the restorations is considerably affected by the materials and techniques used when making dental crowns. This chapter contains reviews on marginal fitting and caries.

Purpose This study evaluated the impact of artifacts generated by metal crowns on the detection of proximal caries lesions in teeth at various distances using cone-beam computed tomography (CBCT). Additionally, the diagnostic impacts of tube current and metal artifact reduction (MAR) were investigated. Materials and Methods Thirty teeth were arranged within 10 phantoms, each containing 1 first premolar, 1 second premolar, and 1 second molar. A sound first molar (for the control group) or a tooth with a metal crown was placed. Of the 60 proximal surfaces evaluated, 15 were sound and 45 exhibited enamel caries. CBCT scans were acquired using an OP300 Maxio unit (Instrumentarium, Tuusula, Finland), while varying the tube current (4, 8, or 12.5 mA) and enabling or disabling MAR. Five observers assessed mesial and distal surfaces using a 5-point scale. Multi-way analysis of variance was employed for data comparison, with P <0.05 indicating statistical significance. Results The area under the curve (AUC) varied from 0.40 to 0.60 (sensitivity: 0.28-0.45, specificity: 0.44-0.80). The diagnostic accuracy was not significantly affected by the presence of a metal crown, milliamperage, or MAR ( P >0.05). However, the overall AUC and specificity were significantly lower for surfaces near a crown ( P <0.05). Conclusion CBCT-based caries detection was not influenced by the presence of a metal crown, variations in milliamperage, or MAR activation. However, the diagnostic accuracy was low and was further diminished for surfaces near a crown. Consequently, CBCT is not recommended for the detection of incipient caries lesions.
