Omega-3 Gel May Help Calm Inflammation in Dental Pulp Repair Material

This laboratory study explored a new type of injectable gel used in dentistry for a procedure called direct pulp capping, where a material is placed over exposed tooth pulp to help protect it. Researchers added omega-3 fatty acids to a common gel material (GelMA) to see if it would change how the gel behaves and how it interacts with cells.

The scientists tested the physical properties of the gel (like its structure, swelling, and strength), and then examined how it affected dental pulp stem cells and immune cells called macrophages, both with and without an inflammatory trigger (LPS, a bacterial component). They also tested the gel in an animal model to see how the body responded to it, including looking at markers of inflammation and immune cell behavior.

The addition of omega-3 to the gel was associated with changes in how the material behaved and how immune cells responded, including markers related to inflammation control. This is a preclinical, materials-science study rather than a study involving people taking omega-3 supplements or fish oil.
