Summary
Augmented-reality-assisted intraoral scanning (ARIOS) demonstrated improved scanning efficiency and user preference over traditional intraoral scanning (IOS). Training significantly enhanced operator proficiency with ARIOS, making it a more ergonomic and user-friendly option.
Area of Science:
- Dental Technology
- Digital Dentistry
- Medical Simulation
Background:
- Intraoral scanning (IOS) has become a standard in digital dentistry.
- Augmented-reality-assisted intraoral scanning (ARIOS) presents a novel approach to enhance the IOS workflow.
- Evaluating new technologies is crucial for advancing dental procedures.
Purpose of the Study:
- To compare scanning time, image count, and precision between ARIOS and IOS.
- To assess participant-related outcomes, including user experience and workload, for both scanning methods.
- To determine the impact of andragogical training on operator proficiency with ARIOS.
Main Methods:
- A within-subject experimental design compared ARIOS and IOS in 25 dental students.
- Participants performed multiple optical scans of a typodont under both conditions after a familiarization session.
- Data collected included scanning time, image count, scan data precision (RMS), and subjective feedback via surveys (including NASA-TLX).
Main Results:
- ARIOS showed a statistically significant decrease in scanning time (mandibular: 8.5%, maxillary: 10.5%) and image count (mandibular: 8.6%, maxillary: 9.3%) compared to IOS.
- Scan data precision, measured by RMS, was comparable between ARIOS and IOS.
- A 7:3 preference for ARIOS was observed in participant exit surveys, with ARIOS rated higher for ergonomics, ease of use, and overall workload.
Conclusions:
- Andragogical training effectively improved operator proficiency with ARIOS.
- ARIOS offers significant advantages in scanning efficacy, ergonomics, ease of use, and reduced overall workload compared to traditional IOS.
- ARIOS represents a promising advancement in intraoral scanning technology for dental education and practice.

01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:26Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.

01:24Prosopagnosia
Prosopagnosia, also known as face blindness, is the inability to recognize faces. In severe cases, individuals with prosopagnosia may not recognize close family members, including parents and spouses, by their faces. For instance, someone with prosopagnosia might walk past their child in a crowd, only realizing their mistake upon noticing their child's distinctive backpack or favorite jacket. Prosopagnosia specifically impairs facial recognition, while the recognition of other objects or...
