Calcium Hydroxide Pulp Capping Agent: An Overview on Composition, Properties, and Clinical Applications

Calcium hydroxide is a commonly used material in pulp capping procedures due to its favourable biological properties, including the ability to promote dentin bridge formation and stimulate reparative dentinogenesis. The mechanical properties of calcium hydroxide, including its compressive strength, flexural strength, and wear resistance, are relatively low, but they are not critical properties in pulp capping procedures. However, the composition and formulation of calcium hydroxide can vary depending on the manufacturer, and this can affect the material's physical and chemical properties, as well as its handling characteristics. Despite these variations, calcium hydroxide remains a popular choice for pulp capping due to its favourable biological properties and its long-standing history of use in dental procedures.
