Summary
Glycerin effectively prevents the oxygen-inhibited layer in dental composites. The optimal protocol involves using glycerin during polymerization and finishing for a smooth, defect-free restoration.
Area of Science:
- Dental Materials Science
- Polymer Chemistry
- Surface Analysis
Background:
- The oxygen-inhibited layer on dental composites can compromise restoration integrity.
- Effective polymerization protocols are crucial for durable and aesthetic dental restorations.
Purpose of the Study:
- To evaluate glycerin's efficacy in preventing the oxygen-inhibited layer.
- To identify the optimal polymerization protocol for composite material finishing.
Main Methods:
- Dental cavities were restored with composite material.
- Samples were treated with glycerin and subjected to different polymerization protocols.
- Surface analysis was performed using a scanning electron microscope (SEM).
Main Results:

Wood surfacing is a critical finishing process designed to smoothen the wood surface, enhance its dimensional accuracy, and make handling safer. This process compensates for potential shrinkage during the seasoning phase by marginally increasing the wood dimensions before surfacing. It also helps correct some distortions that may occur as the wood dries.
The equipment used in the surfacing process is a plane equipped with rotating blades. This tool efficiently smoothens the wood surface and can...

01:14Polymer Classification: Architecture
3.1K
Polymers are classified as linear or branched on the basis of their chain architecture. The polymer chains in linear polymers have a long chain-like structure with minimal to no branching at all. Even if a polymer features large substituent groups on the monomer, which appear as branches to the skeleton, it is not considered a branched polymer. A branched polymer contains secondary polymer chains that arise from the main polymer chain. The branching occurs when the polymer growth shifts from...

01:03Step-Growth Polymerization: Overview
3.8K
Step-growth or condensation polymerization is a stepwise reaction of bi or multifunctional monomers to form long-chain polymers. As all the monomers are reactive, most of the monomers are consumed at the early stages of the reaction to form small chains of reactive oligomers, which then combine to form long polymer chains in the late stages. Hence, the reaction has to proceed for a long time to achieve high molecular weight polymers.

3.2K
Unlike ionic or small covalent molecules, polymers do not form crystalline solids due to the diffusion limitations of their long-chain structures. However, polymers contain microscopic crystalline domains separated by amorphous domains.
Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
