Objective To analyze the research hotspots and development trends in the field of cracked teeth.

Method  The literature related to cracked teeth published from the establishment of the Web of Science database to June 29, 2022 was searched on the computer, and the included literature was visually analyzed by VOSviewer software and Prism Graphpad software to present the number of published papers, literature types, distribution of national institutions, journal sources, citations, and network analysis of researchers' co-authorship of relevant studies, and the keywords co-occurrence and cluster.

Result  A total of 518 pieces of literature related to cracked teeth were included. In terms of study type, 442 (85.3%) were articles and 32 (6.2%) were reviews. The United States was the country with the largest number of published papers, followed by China. The top ten journals with the largest number of publications were all from European and American countries, among which Journal of Endodontics has the largest number of papers (69, 13.3%). The total number of citations of 518 articles was 10,141, and the mean number of citations per article was 19.58. Highly cited literature was associated with the etiology, pathogenesis, and prevention of cracked teeth. The authors with most published articles are Ferracane JL, Funkhouser E and Hilton TJ. Keywords co-occurrence analysis showed that the research hotspots mainly focused on the diagnosis, etiology, and prevention of cracked teeth.

Conclusion  The diagnosis and prevention of cracked teeth are still  hot direction of research. Researchers can enhance the conduction of high-quality clinical research according to these hotspots.
