Harnessing Artificial Intelligence to Predict Dental Crowding in Modern Orthodontic Practice: A Comprehensive Review

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Dental crowding is fundamental to orthodontic diagnosis and treatment planning, yet what constitutes “crowding” remains surprisingly heterogeneous. Space analysis quantifies tooth size–arch length discrepancy, irregularity indices characterize alignment displacement, and clinician‐assigned severity reflects broader diagnostic interpretation ...

Characterization and Repetition Rate Locking of a 1 GHz Erbium‐Doped ZBLAN Waveguide‐Chip Comb Laser

Laser &Photonics Reviews, EarlyView.
A compact, erbium‐doped ZBLAN waveguide chip mode‐locked laser that self‐starts, delivers stable ultrashort pulses, and repetition rate locked to a 1 GHz radio‐frequency reference. The laser produces near transform‐limited 324 fs pulses and 12 nm bandwidth with low noise and long‐term stability, with potential applications in optical frequency ...

Host–Dopant Engineering of Ce4+‐Dominant Y3(Al,Ga)5O12:Ce,Mg Scintillators for High‐Performance X‐Ray Imaging

Laser &Photonics Reviews, EarlyView.
Mg2+ co‐doping strongly suppresses defect‐related emission and luminescence from trace impurities. Moreover, Mg2+ co‐doping improves the scintillation performance of Y3Al3Ga2O12:Ce by increasing the light yield and accelerating the decay time.

Broadband Chromatic Dispersion of Thermo‐Refractive Coefficients and Its Impact in Silicon Nitride Nonlinear Photonics

Laser &Photonics Reviews, EarlyView.
Chromatic dispersion of material thermo‐refractive coefficients is characterized across an octave in integrated Si3N4${\rm Si}_3{\rm N}_4$/SiO2${\rm SiO}_2$ platforms. A 7% variation is observed from telecom to visible wavelengths, while incorporating this dispersion into multiphysics modeling captures frequency‐dependent resonance shifts and improves ...

Characterization of Dental Composite Resin with Additional TiO2 Nanoparticle Filler

Macromolecular Symposia, EarlyView.
Silanized SiO2‐based dental composite resins with and without TiO2 nanoparticle addition were fabricated using a Bis‐GMA/TEGDMA resin matrix and photopolymerized under 468‐470 nm UV light. The resulting composites, composite I (55% SiO2) and composite II (50% SiO2 + 5% TiO2), were characterized via scanning electron microscopy (SEM), Fourier transform ...
