Effectiveness of a nanoemulsion-containing Nigella sativa nanoparticles encapsulated in propolis nanomicelles on dentin tubule occlusion: An scanning electron microscopy study

Nanoemulsion containing <i>Nigella sativa</i> nanoparticles within propolis nanomicelles demonstrated superior dentinal tubule occlusion compared to fluoride varnish, with notable resistance to acid and brushing challenges. Given their natural origin, anti-inflammatory, and remineralizing properties, such nanoformulations may offer an effective and biocompatible alternative for managing DH. Clinical studies are recommended to validate these findings <i>in vivo</i>.
