The PerioMind system, developed on top of the graph, demonstrated efficient parsing of natural language queries and the generation of professional responses. The system achieved the following evaluation scores (out of 5): accuracy 4.8, interpretability 4.4, domain relevance 4.8, and completeness 4.5.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>This study developed a structured knowledge graph and the PerioMind system for periodontology, supporting intelligent diagnosis, education, and research.
