To advance the understanding of organoid technology and facilitate its translation into pulp regenerative medicine, this review provided a comprehensive overview of organoids, encompassing their developmental history, self-organization mechanisms, fundamental definitions, and current applications. Building on this foundation, we highlighted recent progress in oral and maxillofacial organoid research, with a particular focus on the construction of dental pulp organoids. Additionally, we systematically summarized the commonly employed construction methods and explored innovative bioengineering strategies that hold promise for future applications.
