Intraoral digital scans: Part 2—influence of ambient scanning light conditions on the mesh quality of different intraoral scanners [PDF]

The Journal of Prosthetic Dentistry, 2020
STATEMENT OF PROBLEM Digital scans should be able to accurately reproduce the different complex geometries of the patient's mouth. Mesh quality of the digitized mouth is an important factor that influences the capabilities of the geometry reproduction of an intraoral scanner (IOS).

Smart Denture with Embedded Thin‐Film Temperature Sensors Patterned by Femtosecond Laser Pulse for Elderly Healthcare

Advanced Intelligent Systems, Volume 7, Issue 3, March 2025.
We demonstrate the direct‐laser patterning of a gold thin film on polymethyl methacrylate to fabricate a temperature sensor for dentures. The temperature sensor‐embedded smart dentures are evaluated in an oral environment, enabling in‐situ monitoring for elderly healthcare.

Early stages of tooth development in the harbor porpoise Phocoena phocoena

The Anatomical Record, EarlyView.
Abstract Here we describe the stages of tooth development in toothed whales on the basis of the harbor porpoise (Phocoena phocoena). The aim of the study was to find out whether these stages are identical to those of other mammals analyzed so far although toothed whales are homodont and monophyodont.
