An Exploratory Comparative Analysis of Mixed Reality Simulation Versus 3D‐Printed Models for Undergraduate Training in Third Molar Removal

Journal of Dental Education, EarlyView.
ABSTRACT Purpose/Objectives To compare the effectiveness of MR simulation and 3D‐printed models in training undergraduate students in wisdom tooth removal, and to assess students’ perceptions of the MR simulator. Methods Students trained first on either the MR simulator or 3D‐printed plastic models and then repeated the training using the other method ...

3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

Journal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.

Patient regret in tooth extraction for periodontitis: Highlighting the role of patient involvement in decision‐making

Journal of Periodontology, EarlyView.
Abstract Background Tooth extraction is one of the most common irreversible treatment options in dentistry, and it may lead to complex emotional responses such as patient regret. This study aimed to assess the extent of decisional regret among patients who underwent tooth extraction due to periodontal disease and to identify associated influencing ...

Arabinoxylan‐enriched fraction from durum wheat meal modulates structure, texture, nutritional and sensory properties of extruded snacks

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Arabinoxylans (AX), abundant in wheat bran, represent a valuable yet underutilized fraction of cereal milling by‐products. In this study, an AX‐enriched fraction obtained from durum wheat meal (DWM), produced from defatted durum wheat germ and debranning fractions, was incorporated at increasing levels (0–25%) into pea starch ...
