Molar teeth impaction on panoramic radiography

Padjadjaran Journal of Dentistry, 2015
Introduction: The third molar are the most frequently impacted tooth. Characteristic of impacted third molar in every person may be different. Third molar are the last erupted tooth in dental arch and grow during the final period of growth, therefore ...

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

Advanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.

Tooth Movement Following Third Molar Removal

Australasian Orthodontic Journal, 1994
The mandibular dental arches of 45 young adults (mean age = 24.3 years) were analyzed by measuring study casts taken immediately before and twelve weeks after the removal of impacted third molar teeth. Arch length and width were measured at predetermined

Deciphering Small Molecule Diffusion Parameters Across Light Responsive Polymersome Membranes

Advanced Functional Materials, EarlyView.
Light‐responsive polymersomes bearing donor–acceptor Stenhouse adducts (DASAs) enable programmable control over small‐molecule transport across synthetic membranes. By systematically varying DASA density, an optimal functionalization regime is identified that maximizes light‐gated permeability.

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance

Advanced Functional Materials, EarlyView.
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

High‐Resolution and Real‐Time In Situ Generation of Cellular Spheroids by Laser‐Assisted Bioprinting for Guided Microvascularization

Advanced Functional Materials, EarlyView.
Micro‐injection laser‐assisted bioprinting enables ultrafast and precise patterning of small endothelial cell spheroids by injecting a highly concentrated single‐cell suspension into GelMA/ColMA hydrogels. In co‐culture with fibroblasts, controlled pre‐vasculogenic network formation is obtained at microscale resolution.

Dentofacial Morphology in Third Molar Agenesis

Turkish Journal of Orthodontics, 2015
Objective:In the literature, some studies show a relation between tooth agenesis and craniofacial morphology, whereas other authors conclude that dental agenesis exerts little influence on dent facial structures.

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges

Advanced Functional Materials, EarlyView.
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Autotransplantation of a Mature Mandibular Third Molar to Replace Hopeless Mandibular First Molar Autotransplantation of a Mature Mandibular Third Molar to Replace Hopeless Mandibular First Molar [PDF]

Journal of Dental Materials and Techniques, 2013
In this case report, a mature third mandibular molar was transplanted in the socket of a hopeless first mandibular molar of the same quadrant. A 32-year-old woman was diagnosed with strip perforation of her left first lower molar.
