Summary
Calcium hydroxide root canal sealers show mild cytotoxicity but variable antibacterial effects. Further research is needed to confirm their tissue healing properties in endodontic treatments.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Calcium hydroxide has been widely used in endodontic sealers.
- Understanding its properties is crucial for effective root canal therapy.
Purpose of the Study:
- To review laboratory and clinical studies on calcium hydroxide-based root canal sealers.
- To assess their biological and physical characteristics and compare them with other sealers.
Main Methods:
- Extensive literature search of endodontic publications.
- Evaluation of studies on physical properties, biocompatibility, leakage, adhesion, solubility, antibacterial effects, and periapical healing.
Main Results:
- Calcium hydroxide sealers exhibit diverse physical and biological properties.
- Studies indicate mild cytotoxicity but variable antibacterial efficacy.
- Data on tissue healing properties remain inconclusive.
Conclusions:
- Calcium hydroxide-based root canal sealers possess a range of properties.
- Further investigation is necessary to fully elucidate their role in periapical tissue regeneration.

04:01Factors Affecting Solubility
Compared with pure water, the solubility of an ionic compound is less in aqueous solutions containing a common ion (one also produced by dissolution of the ionic compound). This is an example of a phenomenon known as the common ion effect, which is a consequence of the law of mass action that may be explained using Le Chȃtelier’s principle. Consider the dissolution of silver iodide:
01:24Hydration of Cement
Hydration of cement is a chemical reaction between cement particles and water. This process occurs primarily through two mechanisms: through-solution and topochemical. In the through-solution process, anhydrous compounds dissolve into their constituents, hydrates form in the solution, and then precipitate from the supersaturated solution. The topochemical process involves solid-state reactions at the cement particle surface. The through-solution process dominates the topochemical process at the...
01:29Sulfate Attack on Concrete
Sulfate attack on concrete is a deterioration process characterized by a whitish discoloration beginning at the edges and corners, accompanied by cracking and spalling. This phenomenon occurs when sulfates react with the components of hardened concrete, forming compounds like calcium sulfate and calcium sulfoaluminate which occupy more space than the substances they replace, causing the concrete to expand and disrupt.

01:24Carbonation Shrinkage
Atmospheric CO2 penetrates the concrete's pores and, in the presence of moisture, forms carbonic acid, which then reacts with calcium hydroxide in the hydrated cement, forming calcium carbonate. This process reduces the concrete's volume and is termed carbonation shrinkage.
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction facilitates the...

01:22Waterproofing and Anti-Bacterial Admixtures in Concrete
Concrete's susceptibility to water absorption is due to the capillary action within the pores of its hydrated cement paste. This action draws water in, creating the need for waterproofing admixtures to prevent such penetration. The efficacy of these admixtures is contingent upon the water pressure, with variations arising from different conditions such as rain, capillary rise, or hydrostatic pressure in structures intended to hold water.
