Summary
Clearfil DC Core Automix demonstrated the highest tensile bond strength when paired with the Hyper Lightel curing unit. This finding is crucial for optimizing dental composite bonding procedures.
Area of Science:
- Dental Materials Science
- Adhesive Dentistry
Background:
- Dental composites and core materials are essential for restorative procedures.
- Optimizing the bond strength between these materials and dentin is critical for restoration longevity.
Purpose of the Study:
- To evaluate the tensile bond strengths of three adhesive/composite core materials bonded to bovine dentin.
- To compare the efficacy of three different curing units on bond strength.
Main Methods:
- Three adhesive/composite core systems (S6054, UniFil Core, Clearfil DC Core Automix) were tested.
- Three curing units (quartz-tungsten-halogen, high-power quartz-tungsten-halogen, and LED) were utilized.
- Tensile bond strengths were measured after 24-hour water storage at 37°C and analyzed statistically.
Main Results:
- Clearfil DC Core Automix exhibited the highest tensile bond strength.
- The Hyper Lightel (high-power quartz-tungsten-halogen) curing unit resulted in the greatest bond strength when used with Clearfil DC Core Automix.
Conclusions:
- The combination of Clearfil DC Core Automix and the Hyper Lightel curing unit provides superior tensile bond strength to bovine dentin.
- Curing unit selection significantly impacts the bond strength of adhesive/composite core materials.

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...
01:25Accelerated Curing of Concrete
Accelerating concrete curing is achieved by applying heat and additional moisture. This process accelerates the hydration of the cement, resulting in an earlier strength gain in the concrete. Steam curing is a method wherein the concrete products are either transported through a chamber on a conveyor belt or encased in plastic, allowing steam at atmospheric pressure to circulate freely around them. This process begins with a phase of moist curing that typically lasts between 3 to 5 hours, after...
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 ASTM C...

01:17Mortar Properties
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 the...
01:20Curing of Concrete
The hydration of cement takes place within the water-filled capillary pores. However, environmental elements can disrupt this process by evaporating water from the concrete surfaces. Sealed concrete with a water-cement ratio below 0.5 experiences self-desiccation, leading to water loss. The water loss in concrete is mitigated by curing. This technique involves keeping the concrete saturated to maintain the necessary temperature and moisture conditions, to optimally fill the spaces in the cement...
01:21Impact Strength of Concrete
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 does not...
