What is the recommended treatment for caries that is close to the pulp chamber?

The recommended treatment for caries that is close to the pulp chamber involves placing calcium hydroxide directly on the pulp before proceeding with restoration, typically with amalgam. This method is based on the properties of calcium hydroxide, which promotes dentin formation (a process known as dentinogenesis) and helps to create an environment conducive to pulp health. When caries are deep but not yet involving the pulp, calcium hydroxide acts as a barrier, protecting the pulp from further damage and irritation.

Following the application of calcium hydroxide, amalgam is commonly used for restoration since it provides durability and strength, essential for posterior teeth subjected to significant chewing forces. This approach is suitable when the pulp is still vital and has not been irreversibly damaged.

In contrast, other treatment options such as pulpectomy and pulpotomy involve more invasive procedures that are typically reserved for cases where the pulp is already infected or necrotic, rather than when it is merely at risk due to deep caries. Zinc oxide eugenol cement can serve as a restorative material or temporary base but does not promote pulp health in the same way that calcium hydroxide does. Therefore, the combination of calcium hydroxide application followed by a restoration with amalgam is the most
