Porosity in Cement Paste

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...

Summary

This summary is machine-generated.

Mineral-releasing calcium-phosphate cement (Ca-PO(4)) aids in remineralizing dentin. Acid etching before applying the cement significantly boosted dentin microhardness after 3 months in vivo.

Background:

Minimally invasive caries removal preserves dentin.
Mineral-releasing cements can promote dentin remineralization.
Indirect pulp capping aims to maintain pulp vitality.

Purpose of the Study:

Evaluate the in vivo remineralization of caries-affected dentin using resin-based calcium-phosphate cement (Ca-PO(4)).
Assess the effect of acid etching on the remineralization capacity of the cement.

Main Methods:

Permanent teeth indicated for extraction were excavated and restored with or without Ca-PO(4) base.
Teeth were restored with adhesive restorations.
After 3 months in vivo, teeth were extracted for in vitro microhardness analysis of the cavity floor.

Main Results:

Caries-affected dentin treated with acid etching prior to Ca-PO(4) cement showed significantly increased Knoop microhardness.
The non-etched Ca-PO(4) group showed similar results to the control (no cement).
Acid etching enhanced the microhardness of residual dentin near the interface.

Conclusions:

Acid etching prior to Ca-PO(4) cement application enhances dentin remineralization and microhardness.
This technique shows promise for preserving and repairing caries-affected dentin.
Resin-based Ca-PO(4) cement is a viable option for indirect pulp capping when combined with appropriate surface treatment.
