Summary
Mineral trioxide aggregate (MTA) is a versatile endodontic material. This review examines various MTA-like materials, exploring their composition and applications in dental treatments.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Mineral trioxide aggregate (MTA) is a widely used material in endodontics.
- MTA is composed of refined Portland cement, bismuth oxide, and trace elements like SiO₂, CaO, MgO, K₂SO₄, and Na₂SO₄.
- Hydrated MTA exhibits an alkaline pH, starting at 10.2 and increasing to 12.5 within three hours.
Purpose of the Study:
- To review Mineral Trioxide Aggregate (MTA)-like materials.
- To provide an overview of MTA derivatives and their characteristics.
Main Methods:
- Literature review of MTA and MTA-like materials.
- Analysis of material composition and properties.
Main Results:
- MTA is a mixture of Portland cement and bismuth oxide.
- Several MTA-derived materials exist, including Endo-CPM Sealer, Ortho MTA, MTA-Fillapex, DiaRoot BioAggregate, MTA Bio, light-cured MTA, tricalcium silicate, and iRoot SP.
- MTA's hydration process leads to a significant increase in pH.
Conclusions:
- MTA is a significant material in endodontic therapy.
- A growing number of MTA-like materials are available, offering alternatives with potentially varied properties and applications.

01:29Aggregates Classification
991
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

01:26Unsoundness of Aggregate due to Volume Change
517
Unsoundness in aggregates due to volume changes is primarily caused by the physical alterations aggregates undergo, such as freezing and thawing, thermal changes, and wetting and drying. Unsound aggregates, when subjected to these changes, result in volume change upon disintegration. This, in turn, contributes to the deterioration of concrete, including scaling, pop-outs, and cracking. Particular types of aggregates, such as porous flints, cherts, and those containing clay minerals, are...

01:29Preplaced Aggregate Concrete
501
Preplaced aggregate concrete is ideal for construction environments that are not easily accessible. The process begins by properly wetting the gap-graded coarse aggregates to remove the dirt, then placing it in the form and compacting it. Voids are filled with a mortar mix pumped under pressure through slotted pipes. This mortar typically consists of Portland cement, pozzolan, fine aggregates, water, and a fluidizing aid. The pozzolan helps reduce bleeding and segregation while improving the...

01:21Pozzolans
848
Pozzolans are siliceous or aluminous materials blended with Portland cement. They interact with the calcium hydroxide produced during the hydration of Portland cement and contribute to improved strength and durability of concrete. The pozzolanic activity, a measure of a pozzolan's effectiveness, is typically assessed using the strength activity index, as defined in ASTM C 618-93, which calculates the ratio of the compressive strength of cement mixtures with and without pozzolan.

01:29Mortar
881
Mortar, a mixture of Portland cement, hydrated lime, sand, and water, is a crucial binding material in construction. Its primary function is to join masonry units together, filling gaps and ensuring a uniform distribution of weight across the structure. This helps in preventing potential weaknesses. Mortar also serves as a protective barrier against environmental elements such as water and wind, thereby safeguarding the interior of the structure. It also compensates for surface irregularities...

01:22Toughness and Hardness of Aggregate
1.1K
Toughness and hardness are critical properties of aggregate materials used in concrete, particularly on pavement surfaces and industrial flooring subjected to heavy loads. Toughness is defined as the aggregate's resistance to failure by impact and is measured by the aggregate impact value (AIV). For this, the aggregate impact value test is performed, wherein the impact is delivered by a standard hammer, which falls freely under its own weight onto the aggregates. The aggregates fragment in...
