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.

Seeing Through the Face: Robust Facial Diagnosis Enhanced by Landmark Detection and Pose Normalization

Advanced Intelligent Systems, EarlyView.
This study proposes a robust, generalizable new approach for facial type diagnosis. Based on landmark detection and pose normalization, a 94.7% diagnostic accuracy is achieved by Combined Heatmap Regression and Coordinate Regression network. This research makes the AI‐generated preliminary diagnosis more interpretable and reducing the impact of ...

Pre-warming of dental composites

Dental Materials, 2011
Cavity lining with flowable composites have been proposed to improve initial marginal adaptation and minimize shrinkage stresses. The purpose of this study was to evaluate if prewarming of composites would influence the flow and enhance marginal adaptation thus the effect of pre-warming different types of composites on their properties are reported.Six

Nanoparticle release from dental composites

Acta Biomaterialia, 2014
Dental composites typically contain high amounts (up to 60 vol.%) of nanosized filler particles. There is a current concern that dental personnel (and patients) may inhale nanosized dust particles (10(6)cm(-3)). The median diameter of airborne composite dust varied between 38 and 70 nm.

Hydrolytic Degradation of Dental Composites

Journal of Dental Research, 1984
The leakage of filler elements from four composites after storage in water was investigated by use of atomic absorption spectrophotometry. The results confirmed previous findings that leaching of silicon from different composites is strongly dependent on filler composition. Consideration of the total filler surface of each composite material indicated

Novel hydroxyapatite-based dental composites

Biomaterials, 1994
Newly designed composite resins for dental applications have been studied. The matrix phases were based on 2,2 bis-4(2-hydroxy-3-methacryloyloxypropoxy)phenyl propane and a urethane dimethacrylate. Tetrahydrofurfuryl methacrylate was added as a diluent to both dimethacrylates in a proportion of 30 wt%.
