Which type of sealant is often referred to as therapeutic?

The term "therapeutic sealant" refers to a type of sealant that is specifically used to not only protect teeth from decay but also to aid in the remineralization of early carious lesions. Bert and seal is a product that is designed with a therapeutic impact in mind, addressing both preventive and restorative needs by coating teeth that may have early signs of decay, thus helping to halt its progression.

This distinguishes it from preventative sealants, which primarily serve to create a barrier against decay on sound teeth. Incipient sealants are not a standard term in dental terminology and do not specifically refer to a sealant. Composite sealants, while widely used, typically do not have the same therapeutic properties associated with remineralization as Bert and seal does. Therefore, the correct response pertains to a sealant that offers additional therapeutic benefits beyond mere prevention.
