Summary
Mineral trioxide aggregate (MTA) apexification successfully treated a traumatized immature tooth, promoting root development. Late-term surgical intervention ensured long-term healing and function in this pediatric dental trauma case.
Area of Science:
- Dentistry
- Endodontics
- Pediatric Dentistry
Background:
- Traumatized immature permanent teeth often require apexification for root development.
- Injury to the apical papilla can hinder natural root maturation.
- Mineral trioxide aggregate (MTA) is a common material for apexification.
Observation:
- A 7-year-old boy presented with a traumatized, non-vital immature maxillary incisor with signs of infection.
- Initial treatment involved palliative care and MTA apexification.
- The tooth showed continued root development and normal function for 14.5 years.
Findings:
- A late-term complication (17 years post-treatment) necessitated surgical intervention, including root resection and MTA root-end filling.
- Histological analysis revealed a mineralized tissue specimen.
- Long-term follow-up (20 years) confirmed periapical healing and restored tooth function.
Implications:
- This case highlights the potential for successful long-term outcomes with MTA apexification, even with late-term complications.
- Surgical intervention can effectively manage late-term issues in immature tooth apexification.
- Continued root development and function are achievable in severely traumatized immature teeth.

01:13Mortar Joint Deterioration in Masonry
249
Mortar joint deterioration is a significant concern in masonry structures, with water accumulation in the joints leading to damage from freeze-thaw cycles. The repeated expansion of water during freezing and its melting during thawing develop and propagate cracks in the masonry joints. Eventually, this leads to the spalling of mortar from the joints, loosening masonry units and weakening the structure. The deteriorated mortar joints are also vulnerable to moisture intrusion into the walls.

01:26Unsoundness of Aggregate due to Volume Change
287
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...

01:21Aggregate Cement Ratio
453
The Aggregate Cement ratio refers to the weight of aggregate divided by the weight of cement in a concrete mix. Altering this ratio has profound effects on the concrete's properties. This ratio plays a pivotal role in determining the strength, workability, and durability of concrete. When the Aggregate Cement ratio is higher, the mix is leaner, meaning it has less cement paste to lubricate the aggregate, potentially making the concrete less workable. Such mixes, known as lean, enhance the...

01:26Alkali Aggregate Reaction in Concrete
367
The alkali-aggregate reaction in concrete involves natural siliceous minerals in aggregates reacting with alkaline hydroxides derived from cement alkalis. This reaction forms an alkali-silica gel that absorbs water, swells, and increases in volume, which is confined by the surrounding cement paste, creating internal pressures that crack and disrupt the concrete. The extent of expansion and damage can be partly attributed to the alkali-silica reaction's osmotic hydraulic pressure and the...

01:20Microcracking in Concrete
325
Microcracking in concrete refers to the tiny cracks that can form within the material even before any external load is applied. These microcracks typically occur at the interface between the coarse aggregate and the hydrated cement paste, often as a result of differential volume changes prompted by variations in stress-strain behavior, as well as thermal and moisture movement. Initially, these microcracks remain stable and do not grow substantially until the concrete is stressed to about 30...

01:29Preplaced Aggregate Concrete
251
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...
