Summary: The study found that the performance of automatic exposure compensation (AEC) varies between different intraoral radiographic systems. In the RVG 6100 system, the presence of a titanium implant did not affect gray values, but increasing kilovoltage (kV) decreased gray values in all tissues. In the Express system, the presence of the implant and/or increased exposure factors led to a decrease in gray values of enamel and coronary dentine. The distance of the implant did not affect the results.

Summary: This study compared the diagnostic efficacy of different devices in detecting simulated internal root resorption (IRR) and found that the sensitivity and accuracy values were higher with the use of Android Tablet, while lower results were observed with the iMac. Furthermore, the size of the lesion interferes with the detection capacity in the image, but the use of portable devices does not impair the diagnosis of IRR.

Summary: Calcium silicate-based cement (CSC) is widely used in dentistry due to its excellent biocompatibility, sealing ability, and antibacterial activity. This study compared four commercial CSCs and found that premixed CSCs had improved physical properties, with ECPR exhibiting the highest antibacterial properties. However, there were no significant differences in biological properties at 12.5% dilution. Further investigation is needed for clinical situations.

Summary: A systematic review found that regenerative endodontic treatment (RET) showed high survival and success rates in treating traumatized necrotic immature permanent teeth. However, the impact of trauma on the prognosis of RET remains uncertain. Further research is needed to evaluate root maturation using 3-dimensional radiographic evaluations in traumatized teeth, and high-level clinical studies comparing RET with apexification are necessary.

Summary: The aim of this study was to evaluate the influence of different opacities and thicknesses of lithium disilicate on the degree of conversion (DC) and bond strength (BS) of resin cements. Lithium disilicate ceramic samples with high translucency (HT), low translucency (LT), and medium opacity (MO) were used, with varying thicknesses. Both light-cured and dual-cured resin cements were tested for DC and BS. Results showed that an increase in thickness led to a decrease in DC for both cements, while affecting only the BS of the light-cured cement for MO ceramic. Comparing opacities, more translucent ceramics exhibited higher DC values. The LT and MO ceramics showed higher BS values than the HT. Dual-cured cement generally performed better in both analyses. Thicker and more opaque ceramic materials can decrease the DC of the cement, and the BS decreases with increasing thickness of more-opaque ceramics.

Summary: This study compared the measurements of alveolar bone height and width between zero-echo-time MRI (ZTE-MRI) and cone beam CT (CBCT). The results showed good inter- and intra-observer reproducibility for both imaging techniques, with statistically insignificant differences in most bone measurements. The mean measurement differences were also within the range of method error. Therefore, ZTE-MRI is not significantly different from CBCT in measuring alveolar bone height and width.

Summary: The aim of this study was to compare the volume and visual assessment of pulp cavities obtained from 6 different CBCT units with the reference standard of micro-CT. The results showed that Prexion, X1, and Orthophos provided the closest match to the reference standard in terms of 3D reconstructions. Intra- and interexaminer agreements were good to excellent for quantitative measurements. The study concluded that semiautomatic segmentation of CBCT images is a feasible method for producing virtual 3D models of the pulp cavity.

Summary: This single-blind randomized controlled trial aimed to determine if there was a difference in implant treatment outcome and patient-reported outcome measures (PROMs) between osteotome-mediated sinus floor elevation with Bio-Oss Collagen and no grafting material after 1 year of implant loading. The study found no significant difference in any outcome measures between the two treatment groups. Both treatment modalities resulted in high patient satisfaction and improved quality of life.

Summary: This study evaluated the soft tissue remodeling, marginal bone levels, and implant success rate of immediately placed single implants in the maxillary esthetic zone. The results showed a high implant success rate and minimal changes in soft and hard tissues. Patients with thick phenotype showed less papillary recession than thin-phenotype patients.

Summary: The aim of this study was to describe the surveillance and biosafety measures adopted by dentists, dental hygienists, and dental assistants in Brazil's Southern Region, as well as to evaluate access to information during the COVID-19 pandemic. The study used a self-applied and validated online questionnaire and analyzed the availability of healthcare supplies and compliance with recommended biosafety measures. The results showed that certain surveillance measures, such as investigating symptoms and ensuring distancing in waiting rooms, had higher compliance, while procedures related to aerosol prevention had lower compliance, including the use of intraoral radiographs and rubber dams. Additionally, the study found a concerning reliance on non-governmental information sources.

Summary: This study aimed to assess the endo-sinus bone gain after osteotome-mediated sinus floor elevation with Bio-Oss Collagen compared with no grafting material. The results showed that the use of Bio-Oss Collagen significantly increased endo-sinus bone gain compared to no grafting material. Over time, both treatment modalities showed a gradual decrease in endo-sinus bone gain, reducing the difference between the control and test groups.

Summary: This in vitro study evaluated the influence of antimicrobial photodynamic therapy (aPDT), using methylene blue (MB) as photosensitizer (PS) and calcium hydroxide (CH) as intracanal medication on adhesive bond strength, sealing, and integrity of the luting interface of glass-fiber posts to different thirds of endodontically treated root canal dentin. The results showed that aPDT combined with calcium hydroxide can achieve satisfactory adhesive bond strength, sealing, and integrity of the adhesive interface at any intra-radicular depth.

Summary: This study systematically reviewed the application of MRI in the diagnosis of periodontal and/or periapical disease. The findings showed that MRI provides diagnostic information of the hard and soft tissue components affected by these diseases with relatively high sensitivity and specificity. However, there were differences in MRI acquisition protocols and disease definitions among the included studies. Therefore, more research is needed to define the accuracy of this diagnostic modality.

Summary: The study found that 2.5% calcium hypochlorite (Ca(OCl)(2)) had lower cytotoxicity and caused less cell death compared to 2.5% sodium hypochlorite (NaOCl). Both Ca(OCl)(2) and NaOCl negatively affected cell metabolism and lysosome integrity, and disrupted cell structures. Additionally, Ca(OCl)(2) had similar effects on ALP activity as NaOCl, but had a smaller influence on mineralized nodule formation.

Summary: This study aimed to analyze the influence of supracrestal tissue height on peri-implant tissue remodeling in esthetic areas. The results showed that implants with thin supracrestal tissue height had greater bone loss and papillary recession than implants with thick soft tissue height, even when using the one abutment-one time concept. Supracrestal tissue height plays a significant role in peri-implant tissue remodeling.

Summary: Using artificial intelligence for detecting cephalometric landmarks in digital imaging examinations has shown promising results, but there is a lack of consensus on accuracy and precision. A meta-analysis of selected studies revealed AI agreement rates of 79-90% compared to manual detection, with the lowest divergence observed for the menton cephalometric landmark. However, further research is needed to validate AI's strength and effectiveness in different samples.

Summary: Digital diagnostic imaging is essential in implant dentistry. The most commonly used imaging modalities include intraoral periapical radiographs, panoramic views, and cone beam computed tomography (CBCT). The future of implant dentistry is expected to involve digital workflows, artificial intelligence, and ionising-radiation-free imaging modalities.

Summary: This study compared the measurements of height, width, and area in alveolar bone sites using magnetic resonance imaging (MRI) and cone beam CT (CBCT). The results showed that bone height measurements were similar using both CBCT and MRI, while ZTE-MRI resulted in smaller estimates for bone width and area.
