Inappropriate acetabular component angular position is believed to increase the risk of hip dislocation after total hip arthroplasty. However, manual measurement of these angles is time consuming and prone to interobserver variability. The purpose of this study was to develop a deep learning tool to automate the measurement of acetabular component angles on postoperative radiographs.

Two cohorts of 600 anteroposterior (AP) pelvis and 600 cross-table lateral hip postoperative radiographs were used to develop deep learning models to segment the acetabular component and the ischial tuberosities. Cohorts were manually annotated, augmented, and randomly split to train-validation-test data sets on an 811 basis. Two U-Net convolutional neural network models (one for AP and one for cross-table lateral radiographs) were trained for 50 epochs. Image processing was then deployed to measure the acetabular component angles on the predicted masks for anatomical landmarks. Performance of the tool was tested on 80 AP and 80 cross-table lateral radiographs.

The convolutional neural network models achieved a mean Dice similarity coefficient of 0.878 and 0.903 on AP and cross-table lateral test data sets, respectively. The mean difference between human-level and machine-level measurements was 1.35° (σ= 1.07°) and 1.39° (σ= 1.27°) for the inclination and anteversion angles, respectively. Differences of 5⁰ or more between human-level and machine-level measurements were observed in less than 2.5% of cases.

We developed a highly accurate deep learning tool to automate the measurement of angular position of acetabular components for use in both clinical and research settings.

Pneumatosis intestinalis (PI) is a rare condition usually occurring among adults who have undergone solid organ transplant and are taking steroid therapy. The coronavirus disease 2019 (COVID-19) virus uses angiotensin-converting enzyme 2 in gastrointestinal epithelium as a receptor for entry process. Due to the steroid intake, the COVID-19 virus is present in the patient's gastrointestinal tract for extended period of time. It may therefore increase the possibility of PI in such patients. It is usually asymptomatic, with a clinical spectrum ranging from indolent to life-threatening. Unfortunately, there are no algorithms concerning diagnosis and treatment of PI.

The aim of this study is to highlight the problem of PI induced by COVID-19, especially in high-risk groups such as solid organs recipients.

On the basis of the presented case of a severe course of COVID-19-induced PI, we conclude that laparotomy with bowel resection can be a feasible and a safe option for treatment.

The predoctoral dental curriculum includes didactic lectures, demonstrations, and training on shade-matching techniques and protocols. However, a significant percentage of esthetic failures are still observed clinically. An assessment is required to determine whether reevaluation and modification of this training protocol would help future dental practitioners better perceive and communicate the dental shade.

The purpose of this study was to evaluate dental students' knowledge of and skill in shade selection and effective prescription writing before and after educational training with 3 different shade guides.

Thirty predoctoral dental students (interns) who had completed their academic program and were undergoing clinical training were selected. https://www.selleckchem.com/mTOR.html After excluding color vision deficiency, the study participants were first asked to evaluate the shade of the right maxillary central incisor of 5 patient participants by using 3 different shade guides (Vitapan Classical, Vitapan 3D-MASTER, Chromascop) under strriculum.
A significant difference in prescription scoring was observed after training, along with a higher percentage shade match and percentage agreement. This indicated a need to reconsider the educational training provided for dental shade assessment and communication and to implement better protocols in the dental curriculum.
The accuracy of single implant placement is critical, as errors may cause problems with vital structures intraoperatively, as well as postoperatively with the prostheses. These issues may be exacerbated in complete-arch edentulous treatments requiring relative accuracy among multiple implants, particularly with prefabricated prosthetic structures.

The purpose of this clinical study was to determine the accuracy of dental implant placement by using haptic robotic guidance in completely edentulous participants.

In a prospective single-arm clinical study, 5 qualified participants elected to receive dental implants placed by using haptic robotic guidance to restore either the maxillary or mandibular arch, or both, with complete-arch implant-supported prostheses. Three dual-arch participants and 2 single-arch participants resulted in 38 endosteal dental implants being placed. A virtual preoperative restorative and surgical plan was created before surgery. This plan was matched to the surgical workspace on the necessary to measure outcomes and to assess differences as compared with nonrobotic implementations, haptic robotic preparation appears to confer additional intraoperative advantages over other techniques for treating completely edentulous arches.
This clinical series for treating completely edentulous patients by using haptic robotic guidance was found to be safe and accurate. While further longer-term clinical studies are necessary to measure outcomes and to assess differences as compared with nonrobotic implementations, haptic robotic preparation appears to confer additional intraoperative advantages over other techniques for treating completely edentulous arches.
Current computer-aided design and computer-aided manufacturing (CAD-CAM) technology has digitalized some traditional prosthodontic processes, but manual interventions are still needed for both clinical and dental laboratory procedures, and improved digital workflows are required.

The purpose of this retrospective clinical study was to develop a straightforward completely digital workflow to fabricate monolithic zirconia crowns and evaluate clinical efficiency and prosthetic outcomes.

Self-glazed zirconia crowns (N=229) were placed in 177 participants between 2016 and 2019 with a completely digital workflow. The extent of clinical adjustment needed for each crown was recorded and then divided into 3 categories zero adjustment, minimal adjustment, and unacceptable. Color match and marginal adaption were evaluated according to the modified US Public Health Service (USPHS) criteria.

A total of 213 (93.0%) crowns required zero adjustment during clinical evaluation, 11 (4.8%) needed minimal adjustment, and 5 (2.
