Autogenous dentin graft (ADG) represents a promising autologous grafting material for bone reconstruction, owing to its low immunogenicity, inherent osteoinductive properties, and straightforward processing. This study employs bibliometric analysis to examine the research progress and emerging trends in ADG, assessing the scholarly contributions of institutions, journals, and authors from different countries and regions. Publications on ADG from 2006 to 2025 were retrieved from the Web of Science Core Collection database. Bibliometric and visual analyses were performed using VOSviewer, CiteSpace, and R package 'bibliometric'. A total of 559 publications on ADG were identified. China led in research output with 61 articles, and Seoul National University was the most prolific institution, contributing 67 publications. Kim Young-Kyun emerged as the leading author, with an H-index of 18 and 23 publications. The Clinical Oral Implants Research was the most influential journal contributing the most publications. Keywords cluster analysis showed 4 main clusters were identified, including ADG for implant placement, ADG for alveolar ridge augmentation, combination with other materials and advantages of ADG. Keywords burst analysis showed emerging interests in 'guided bone regeneration' (2022-2025) and 'growth factors' (2023-2025). This bibliometric analysis provides an overview of global research trends in ADG. The frontiers in this field may be validation of efficacy of the demineralized ADG-derived membrane and development of standardized protocol for demineralized ADG to further improve patient prognosis.
