Porosity in Cement Paste01:18

Porosity in Cement Paste

The porosity of concrete is a measure of the void spaces within its structure. These spaces impact its strength and durability significantly. When water and cement interact, a chemical reaction called hydration creates a semi-solid paste. This paste includes combined water, making up approximately 23% of the cement's dry mass, and gel water, which fills minuscule voids known as gel pores, accounting for about 28% of the cement gel volume.
The balance of water to cement in the mix is critical—it...
Porosity and Absorption of Aggregate01:20

Porosity and Absorption of Aggregate

Aggregates contain pores of varying sizes; while some are completely enclosed within the particles, others open onto the surface, allowing water to penetrate. The porosity of aggregates is a major factor contributing to the overall porosity of concrete, given that aggregates constitute about three-quarters of concrete's volume.
When all pores in an aggregate are filled with water, the aggregate is considered saturated and surface-dry. If left in dry air, water will evaporate until the aggregate...

Area of Science:

  • Dentistry
  • Endodontics
  • Dental Materials

Background:

  • Pulp capping historically presented unpredictable outcomes, often leading to contraindication.
  • Mineral trioxide aggregate (MTA) is a novel material exhibiting resistance to bacterial leakage, potentially protecting the pulp.
  • MTA, combined with a sealed restoration, may facilitate pulp repair and maintain vitality.

Purpose of the Study:

  • To evaluate the efficacy of mineral trioxide aggregate (MTA) as a direct pulp-capping material.
  • To assess the long-term outcomes of vital pulp therapy using MTA in permanent teeth with reversible pulpitis.

Main Methods:

  • Forty patients (ages 7-45) with reversible pulpitis underwent direct pulp capping with MTA.
  • Caries removal was followed by MTA application to exposures and surrounding dentin.
  • A two-visit protocol included provisional and final bonded composite restorations, with follow-up evaluations for up to nine years.

Main Results:

  • A nine-year follow-up of 49 teeth revealed a 97.96% favorable outcome rate based on radiographic, symptomatic, and cold testing assessments.
  • All 15 teeth in younger patients with open apices demonstrated completed root formation (apexogenesis).

Conclusions:

  • Mineral trioxide aggregate (MTA) proves to be a reliable material for direct pulp capping on carious exposures in permanent teeth.
  • A two-visit treatment protocol is crucial for successful vital pulp therapy using MTA.
  • Vital pulp therapy with MTA is a viable treatment option for teeth diagnosed with reversible pulpitis.
