Purpose: Bone grafts can be challenging to assess on cone-beam computed tomography (CBCT) examinations due to their discreet appearance and the potential introduction of metallic artifacts from implant screws. This study aimed to evaluate the effect of CBCT milliamperage (mA) on detecting bone graft dehiscence adjacent to titanium (Ti) and zirconia (Zr) implants. Materials and Methods: Twenty Ti and 20 Zr implants were installed in bovine rib blocks. Gaps of at least 2 mmwere created between the implant and the bone and filled with particulate autogenous bone grafts. In half of the blocks, the gap was completely filled, while in the other half, the grafting material was removed up to the thirdimplant thread. CBCT images were acquired at 4, 6.3, and 10 mA and evaluated by 5 observers to detect bone graftdehiscence. The area under the receiver operating characteristic curve, accuracy, sensitivity, and specificity werecalculated. These values were then compared across various dental implant materials and mA levels using 2-wayanalysis of variance with a significance level of 5%. Results: No statistically significant differences were observed in the diagnostic values for bone graft dehiscencebetween implant types (P>0.05) or mA settings (P>0.05). Conclusion Although a protocol with lower radiation exposure (that is, lower mA) could be employed, the use of CBCT for evaluating bone graft dehiscence adjacent to different types of dental implants should be approached with caution.

Purpose: This study was conducted evaluate the influence of reconstruction parameters of micro-computed tomography (micro-CT) images on bone mineral density (BMD) analyses. Materials and Methods: The sample consisted of micro-CT images of the maxillae of 5 Wistar rats, acquired using a SkyScan 1174 unit (Bruker, Kontich, Belgium). Each acquisition was reconstructed following the manufacturer's recommendations (standard protocol; SP) for the application of artifact correction tools (beam hardening correction [BHC], 45%; smoothing filter, degree 2; and ring artifact correction [RAC], level 5). Additionally, images were reconstructed with 36 protocols combining different settings of artifact correction tools (P0 to P35). BMD analysis was performed for each reconstructed image. The BMD values obtained for each protocol were compared to those obtained using the SP through repeated-measures analysis of variance with the Dunnett post hoc test (α=0.05). Results: The BMD values obtained from all protocols that used a BHC of 45% did not significantly differ from those obtained using the SP (p>0.05). The other protocols all yielded significantly different BMD values from the SP (p<0.05). The smoothing and RAC tools did not affect BMD values. Conclusion BMD values measured on micro-CT images were influenced by the BHC level. Higher levels of BHC induced higher values of BMD.

Nasal myiasis is an infestation by dipterous larvae within the nasal cavity, where they feed on both living tissue andfluid. This condition predominantly occurs in rural areas of tropical countries, where inadequate sanitation and ahot, humid climate create an ideal environment for larvae development. A 57-year-old, otherwise healthy male ruralworker presented with a toothache in the region of the maxillary incisors. Imaging studies identified a punctiformradiopaque/hyperdense area near the nasal septum in the left nasal fossa. The larva was surgically excised andsent for histopathological analysis. Histologic sections confirmed the clinical diagnosis, and the patient remainedasymptomatic after a 2-month follow-up. Nasal myiasis can mimic the symptoms of a toothache in the anterior region of the maxilla. This condition can affect even immunocompetent patients, and complementary imaging studies may be decisive in diagnosing it.

Purpose: The aim of this study was to identify, compile, and report the technical specifications of current and historical intraoral digital radiographic systems and recommend standardised reporting practices for production companies. Materials and Methods: A comprehensive report was prepared on 150 intraoral digital radiographic systems, comprising 105 sensor-based (70%) and 45 phosphor storage plate (PSP)-based systems (30%). Technical specifi cations were obtained from official company sources and scientific articles to ensure a complete collection of available data. Results: These systems were produced by 55 companies across 11 countries, with the United States leading (35.3%), followed by France (12%). Among the sensor systems, 76.2% used complementary metal-oxide-semiconductor (CMOS) technology, with notable variations in sizes and resolutions. PSP systems were available in 7 plate sizes and displayed diverse resolutions and scanning times. Twenty-one companies produced both sensor- and PSP-based systems, 33 produced only sensor-based systems, and 1 produced exclusively PSP-based systems. Conclusion This report identified 150 digital radiographic systems, revealing wide variability in technicalspecifications and a lack of standardised reporting protocols. The comprehensive summary and recommendations forconsistent documentation provided here can help clinicians make informed decisions and encourage manufacturers and production companies to adopt uniform reporting standards aligned with local regulatory frameworks.
