Summary
Resin-based root canal sealers exhibit the lowest solubility, making them ideal for dental applications. All tested sealers met ISO standards, but resin-based options offer superior insolubility for effective apical sealing.
Area of Science:
- Endodontics
- Dental Materials Science
Background:
- Root canal sealers are crucial for apical sealing to prevent bacterial invasion.
- Material insolubility is a key characteristic for effective root canal sealers in dentistry.
Purpose of the Study:
- To evaluate and compare the solubility of six different root canal sealers.
- Tested materials included zinc oxide-eugenol (ZnOE), calcium hydroxide, and resin-based sealers.
Main Methods:
- Solubility was assessed by measuring weight loss (%) after 24 hours and 2 months in water.
- Standardized specimens were tested according to ISO 6876 and ADA specifications No. 30 and No. 57.
- Statistical analysis was performed using a one-way ANOVA.
Main Results:
- Significant differences in solubility were observed among the tested root canal sealer groups.
- Resin-based sealers demonstrated significantly lower solubility percentages compared to ZnOE and calcium hydroxide sealers.
- No significant solubility difference was found between the resin-based sealers tested.
Conclusions:
- All evaluated root canal sealers met the <3% weight loss criteria of ISO 6876 and ADA specifications.
- Resin-based root canal sealers exhibited the lowest solubility, indicating they are virtually insoluble.
- The superior insolubility of resin-based sealers makes them highly suitable for endodontic applications.

Solution, Solubility, and Solubility Equilibrium
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...

01:09Solubility Equilibria: Overview
When a substance such as sodium chloride is added to water, it dissolves, forming an aqueous solution. The extent of dissolution is called solubility. The process of dissolution can exist in equilibrium, just like other chemical processes. Solubility equilibria are also called precipitation equilibria because the process of solubility can be reversible. The reverse of the solubility process is called precipitation.
