AI in Dental Radiology-Improving the Efficiency of Reporting With ChatGPT: Comparative Study.

Background: Structured and standardized documentation is critical for accurately recording diagnostic findings, treatment plans, and patient progress in health care. Manual documentation can be labor-intensive and error-prone, especially under time constraints, prompting interest in the potential of artificial intelligence (AI) to automate and optimize these processes, particularly in medical documentation.

Objective: This study aimed to assess the effectiveness of ChatGPT (OpenAI) in generating radiology reports from dental panoramic radiographs, comparing the performance of AI-generated reports with those manually created by dental students.

Assessing cytotoxicity: a comparative analysis of biodegradable and conventional 3D-printing materials post-steam sterilization for surgical guides.

Ecological concerns and the depletion of petroleum resources have driven the exploration of biodegradable 3D-printing materials derived from bio-renewable sources, such as polylactic acid (PLA) and polyhydroxyalkanoates (PHA). This study aimed to compare the potential cytotoxic effects of a biodegradable PLA/PHA blend filament, a conventional photopolymer (MED610), and a combination of MED610 with a support material (SUP705) before and after steam sterilization in vitro, with a focus on their application in the production of surgical guides.PLA/PHA, MED610, and SUP705 (both in their pure and steam-sterilized forms;= 6 per group) were assessed for their cytotoxic effects on human fibroblasts using the neutral red uptake assay.

Evaluation of dental students' learning curve in intraligamentary anesthesia using different syringe systems: A prospective crossover study.

Purpose/objectives: This prospective crossover preclinical trial aimed to evaluate the learning curve of dental students in successfully administering intraligamentary anesthesia (ILA) using three different syringe systems.

Methods: Dental students performed ILA using three devices in two separate sessions, each targeting mandibular and/or maxillary premolars. The devices included two manual systems (pistol-type and lever-based) and one computer-controlled local anesthetic delivery system (CCLAD).

Model-Based Optimization of Solid-Supported Micro-Hotplates for Microfluidic Cryofixation.

Cryofixation by ultra-rapid freezing is widely regarded as the gold standard for preserving cell structure without artefacts for electron microscopy. However, conventional cryofixation technologies are not compatible with live imaging, making it difficult to capture dynamic cellular processes at a precise time. To overcome this limitation, we recently introduced a new technology, called microfluidic cryofixation.

Effects of volume management on free flap perfusion and metabolism in a large animal model study.

Free flap failure represents a substantial clinical burden. The role of intraoperative volume management remains controversial, with valid studies lacking. Here, using a large animal model, we investigated the influence of volume management on free flap perfusion and metabolism.
