Custom sports mouthguards are used in various sports to protect teeth, temporomandibular joints, and soft tissues from impact forces. The present article demonstrates a digital workflow to fabricate a 3-dimensionally (3D) printed individualized sports mouthguard. An optical jaw tracking system is used to record a repeatable reference position, and mandibular excursive movements to achieve a completely balanced occlusion. The technique simplifies the fabrication of a custom-fit mouthguard over the conventional approach by providing increased thickness accuracy, control of design, and integration of jaw motion.

As in general pathology, digitalization is also inexorably making its way into dermatopathology. This article examines the current state of digitalization in German dermatopathology laboratories based on the authors' own experiences, the current study situation, and a survey of members of the Dermatological Histology Working Group (ADH). Experiences with the establishment of a digital laboratory workflow, artificial intelligence (AI)-based assistance systems, and whole slide images (WSI)-based training programs are discussed.

The search for reliable prognostic markers in oral squamous cell carcinoma (OSCC) remains a critical need. Tumor-infiltrating lymphocytes (TILs), particularly T lymphocytes, play a pivotal role in the immune response against tumors and are strongly correlated with favorable prognoses. Computational pathology has proven highly effective for histopathological image analysis, automating tasks such as cell detection, classification, and segmentation.

Article Synopsis
  • The integrated portable and automatic digital detection system (IPADS) is a new tool designed for rapid and accurate diagnosis of infectious diseases through nucleic acid detection.
  • It uses a hybrid magnetic system (HMS) to efficiently extract genetic material, simplifying traditional methods and allowing for quick sample processing with over 80% extraction efficiency.
  • In tests for hepatitis B virus (HBV) DNA, IPADS showed strong alignment with standard PCR methods, proving its potential as a reliable option for point-of-care testing.
