Evaluating Recurring Esthetic Dental Proportion (RED) and Golden Proportion in Natural Dentition

Avicenna Journal of Dental Research, 2016
Background: The width ratio of teeth is an important factor in dental and facial esthetics. The Golden proportion (62%) and the recurring esthetic dental proportion (RED) are two theories in this field that have been suggested to create harmony among anterior teeth. These have rarely been studied among the Iranian population.

Through Diamond Robust Surface Enhanced Raman Spectroscopy

Advanced Functional Materials, EarlyView.
Thin film diamond growth offers a unique opportunity for Surface Enhanced Raman Spectroscopy (SERS); the encapsulation of plasmonic nanostructures within a transparent, chemically stable, and physically robust coating. The diamond acts as both a window and protective layer, enabling illumination of the plasmonic nanostructures through the diamond ...

Injectable Dual‐Network Hydrogel System for Osteochondral Repair Combining Immunomodulation, Mechanical Adaptability, and Enhanced Tissue Integration

Advanced Functional Materials, EarlyView.
A UV‐triggered injectable dual‐network hydrogel is reported as the first application of bletilla striata polysaccharide (BSP) in osteochondral repair. By integrating methacrylamide‐modified BSP and nitrobenzaldehyde‐functionalized hyaluronic acid, the system achieves immunomodulation, mechanical reinforcement, and dynamic tissue adhesion, thereby ...

The Golden Proportion in Dentistry: A Literature Review

Middle East Journal of Rehabilitation and Health, 2016
Context: In the last 2 decades, several studies have questioned the application of the rule of the golden proportion in dentistry. Therefore, the purpose of this review study was to assess the dental use of the golden proportion. Evidence Acquisition: We performed MEDLINE and Cochrane searches for English language literature published through 2015 ...

Dual‐Ligand Metal‐Organic Frameworks via In Situ Amidoxime Engineering for Selective Ion Separation

Advanced Functional Materials, EarlyView.
Inspired by microbial ion‐trapping mechanisms, a mild and universal strategy is developed to construct highly porous amidoxime‐functionalized MOFs. DFT calculations and molecular force measurements reveal that the dual‐ligand amidoxime configuration significantly strengthens Ga(III) affinity.

Palladio’s Villa Emo: The Golden Proportion Hypothesis Rebutted [PDF]

Nexus Network Journal, 2001
In a most thoughtful and persuasive paper Rachel Fletcher comes close to convincing that Palladio may well have made use of the ‘golden section’, or extreme and mean ratio, in the design of the Villa Emo at Fanzolo. What is surprising is that a visually gratifying result is so very wrong when tested by the numbers.
