Summary
Fiber post restorations offer the best functional tooth rescue after endodontic treatment. Traditional long modified fiber posts demonstrate superior resistance to compressive loads, preserving residual dental structures effectively.
Area of Science:
- Dentistry
- Biomaterials Science
- Restorative Dentistry
Context:
- Endodontically treated teeth require functional restoration.
- Fiber-reinforced composite posts (PMF) are a leading solution for tooth rescue.
- Evaluating the mechanical resistance of different PMF designs is crucial for clinical success.
Purpose:
- To assess the fracture resistance of four distinct types of fiber posts under laboratory conditions.
- To compare the performance of traditional long modified PMF against other designs when subjected to compressive forces.
Summary:
- Four types of fiber posts were tested for resistance to fracture under laboratory-simulated loads.
- External pressure was applied until lateral displacement led to specimen fracture.
- Results indicate traditional long modified fiber posts exhibit the highest tolerance to compressive loads.
Impact:
- Identifies traditional long modified fiber posts as optimal for preserving dental structure integrity.
- Provides evidence-based guidance for selecting the most robust fiber post system.
- Contributes to improving long-term outcomes for endodontically treated teeth through enhanced restorative choices.

02:37Types of Chemical Bonds
Chemical bonding theories were pioneered by American chemist Gilbert N. Lewis. He developed a model called the Lewis model to explain the type and formation of different bonds. Chemical bonding is central to chemistry; it explains how atoms or ions bond together to form molecules. It explains why some bonds are strong and others are weak, or why one carbon bonds with two oxygens and not three; why water is H2O and not H4O.

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

01:12Bonding and Strength of Aggregate
The bond between aggregate particles and the cement matrix is significantly influenced by the shape and surface texture of the aggregates. High-strength concretes benefit from a rougher texture, which leads to stronger bonding due to greater adhesion. Angular aggregates with larger surface areas also enhance this bond. The bonding quality, however, is complex to assess as no universally accepted test exists. Good bonding is indicated when a crushed concrete specimen shows some aggregate...
01:12Non-destructive Tests for Concrete Strength
The rebound hammer test, also known as the Schmidt hammer test, is a non-destructive technique for evaluating the hardness of concrete and, indirectly, the strength of concrete. It operates on the principle that the rebound of a spring-driven mass from a concrete surface correlates to the surface's hardness. The device comprises a mass within a tubular housing, a spring mechanism, and a plunger that strikes the concrete. Upon release, the energy imparted to the mass by the spring causes it to...
