Aim: The aims of this study were to identify the most cited articles in Periodontology published from January 1990 to March 2005; and to analyse the differences between citation Classics and less cited articles. Material and Methods: The search was carried out in four international periodontal journals: Journal of Periodontology , Journal of Clinical Periodontology , International Journal of Periodontics and Restorative Dentistry and Journal of Periodontal Research . The Classics, that are articles cited at least 100 times, were identified using the Science Citation Index database. From every issue of the journals that contained a Classic, another article was randomly selected and used as a Control. Results: Fifty‐five Classics and 55 Controls were identified. Classic articles were longer, used more images, had more authors, and contained more self‐references than Controls. Moreover Classics had on the average a bigger sample size, often dealt with etiopathogenesis and prognosis, but were rarely controlled or randomized studies. Conclusions: Classic articles play an instructive role, but are often non‐Controlled studies.
