Summary
Calcimol LC demonstrated superior compressive strength among tested dental liners, both immediately and after 24 hours. This finding suggests its suitability as a standalone liner for restorative materials.
Area of Science:
- Dental Materials Science
- Biomaterials Engineering
Background:
- Compressive strength is a critical property for dental liners.
- Selecting liners with adequate mechanical properties is essential for long-term restoration success.
Purpose of the Study:
- To evaluate and compare the compressive strength of five commonly used dental liners.
- To determine the mechanical performance of these liners under different setting conditions.
Main Methods:
- An in vitro experimental study involving 120 liner samples (Dycal, Calcimol LC, Vitrebond, Activa Bioactive, TheraCal LC).
- Compressive strength testing was performed immediately after setting and after 24-hour water immersion at 37°C.
- Data were analyzed using two-way ANOVA and Tukey's post-hoc test.
Main Results:
- Significant differences in compressive strength were observed among the five liners (p<0.05).
- Calcimol LC exhibited the highest compressive strength at both immediate and 24-hour testing points.
- Compressive strength increased significantly after 24 hours compared to immediate post-setting strength for all liners.
Conclusions:
- Calcimol LC, Activa Bioactive Liner, and TheraCal LC possess adequate compressive strength.
- These liners may be suitable for use as standalone materials, providing sufficient support for restorative dental materials.

01:20Strength of Cement

Strength tests for cement are not performed directly on neat cement paste due to difficulty in obtaining consistent, reliable specimens. Instead, cement is typically tested in the form of cement-sand mortar.
For compressive strength tests, ASTM C 109-05 standards prescribe a cement-sand mix ratio of 1:2.75 and a water/cement ratio of 0.485 for making 2-inch cubes. These cubes are mixed, cast, and cured in saturated lime water at 23°C until testing. Flexural strength testing, outlined in...

01:16Tensile Strength Considerations of Concrete
291
Considering the tensile strength of concrete involves recognizing that the theoretical strength of cement paste can be up to a thousand times higher than what is observed in practical applications. This significant discrepancy is largely attributed to the presence of microscopic cracks within the concrete. These cracks tend to amplify stress at their tips when a load is applied, a phenomenon explained by Griffith's theory of brittle fracture.

01:30Relation Between Tensile Strength and Compressive Strength of Concrete
446
Concrete is a fundamental building material, and understanding its strengths is crucial for construction projects. The relationship between its tensile and compressive strengths is intricate, showing that while these strengths are related, they do not increase at the same rate. Tensile strength's growth is slower and is affected by various factors such as the methods used for testing, the size and shape of the specimen, the texture of the aggregate used, and the moisture content of the...

01:21Impact Strength of Concrete
441
Impact strength in concrete is a critical measure that reflects the material's capability to endure the forces applied during pile driving and when supporting machinery foundations that experience impulsive loads. It is also essential when handling precast concrete components to prevent accidental damage. The impact strength is assessed by observing the concrete's resistance to repeated impacts and energy absorption capacity. A key indicator of significant damage to concrete is when it...

Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...

01:23Behavior of Concrete Under Compressive Load
390
Concrete exhibits specific behaviors under different compressive loads. Understanding this is crucial for understanding its structural integrity. When concrete undergoes uniaxial compression, it tends to develop cracks that run parallel to the direction of the force. These parallel cracks stem from localized tensile stresses that occur perpendicular to the compression direction. Additionally, angled cracks may appear due to the formation of shear planes.
