Summary: Autotransplantation of a mature tooth often leads to pulp necrosis. Root canal treatment is recommended to prevent complications. However, conventional dental radiography cannot visualize extraoral root-end resection. Contrast-enhanced magnetic resonance imaging proved to be useful for observing pulp revascularization after autotransplantation, avoiding the need for root canal treatment.

Summary: We propose a motion estimation and motion correction approach for oral and maxillofacial cone beam CT scans based solely on 2D projection images. This algorithm improves the visualization quality of motion impaired scans, eliminating the need for re-scans and reducing radiation dosage for patients.

Summary: This study compared tooth color and enamel and dentinal thickness between orthodontically treated and untreated individuals. The results showed significant differences in tooth color but not in enamel and dentinal thickness between the two groups. There were weak to moderate correlations between tooth color and enamel and dentinal thickness.

Summary: This study evaluated the precision of a simplified workflow using only preoperative CBCT scans to gain guided access to root canals of extracted mandibular molars. The influence of the presence of coronal restoration in the simplified workflow was also evaluated. The results showed that the simplified digital workflow using only CBCT examination allowed a high level of precision in obtaining access in extracted molars with and without coronal restoration.

Summary: This clinical study evaluated the correlation between Vitamin D (Vit D), cholesterol levels, and T- and Z-scores of dual-energy X-ray absorptiometry (DXA) scans with cone beam computed tomography values in the maxillary and mandibular jaws. A total of 187 patients aged between 45 and 65 were included in the study, divided into control (non-osteoporosis) and case (osteoporosis) groups. The results showed a significant inverse relationship between Vit D and cholesterol in the case group, and a positive relationship between Vit D and cone beam computed tomography values in all regions of the jaws except the mandibular posterior region. Pearson correlation analysis revealed an insignificant negative association between Vit D, cholesterol levels, and cone beam computed tomography values in all regions of the jaws, while Z-values were highly correlated with the cone beam computed tomography values in all regions of the jaws. Vit D, cholesterol levels, and Z-values were found to be related to the cone beam computed tomography values of the jaws in women and men aged 45-65.

Summary: The study found that piezocision-assisted orthodontic maxillary arch expansion does not cause significant changes in cortical plates, except for the premolar region. This suggests that premolars may be at greater risk of buccal plate loss than other teeth.

Summary: A study compared linear measurements of intrabony defects using different CBCT section thicknesses with intraoperative measurements, and found no statistically significant difference between clinical and radiographic bone level measurements at section thicknesses of 0.25, 1, and 3 mm.

Summary: This study evaluated the guided endodontics technique and found it to have high accuracy and low rise in root surface temperature. However, further research is needed to determine its reliability and safety in clinical applications.

Summary: This study compared the pulp volume changes of maxillary anterior teeth after en-masse retraction with or without piezocision-assisted orthodontics, and found that the effect of piezocision-assisted orthodontic tooth movement on pulp volume was similar to conventional orthodontic treatment. The degree of change in pulp volume does not appear to be related to root resorption. Additionally, a statistically significant but moderate correlation was found between the pulp volume change of the right canine and its root length.

Summary: This study evaluated the accuracy of 3D-printed endodontic guides for access cavity preparation in different types of teeth. The results showed that the accuracy was acceptable, with higher deviations in the M group compared to the other groups. Angular deviation was found to best discriminate the canal access ability of guided access cavity preparation.

Summary: CBCT provides advantages for evaluating acute small bone and joint trauma by reliably detecting and excluding extremity fractures and related findings. Additional findings change therapy in one third of patients, suggesting substantial clinical impact.

Summary: CE-CBBCT features are associated with IHC receptors and molecular subtypes of breast cancer, which can help predict IHC receptor status and differentiate molecular subtypes. Specific features such as lesion number, tumor size, and internal enhancement pattern are related to different subtypes.

Summary: The aim of this study was to provide a tool to aid medical doctors in planning endovascular surgery by quickly detecting stenotic vessels and quantifying the degree of stenosis. The use of skeletonization improved the visualization of vessels and the distance transform provided a linear representation of the diameter of critical vessels selected by the user. The system also estimated the exact distance between landmarks and the occlusion, which is crucial information for surgery planning. The proposed tool offers the advantage of examining chosen vessels in a linear representation free from tortuous vascular courses and vessel crossings.
