The citation records of the papers published in the Journal of Periodontology vols. 31–45 and Journal of Periodontal Reserch vols. 1–9 have been examined and lists of most cited papers ranked by total number of citation and citations per year compiled. Several diverse approaches to periodontal research are represented in these lists including microbiology, histology, immunilogy. and surgery.The patterns of periodontal literature usage with time resembles that found for biomedical lliterature and other bibliographic indices such as Price's Index and the number ro references per paper place periodontal research in or close to the range of values found for “normal” sciences.The distribution of citations among individual papers resembles that found in other sciences in that the majority of papers have very little impact. In the first five years following publication, 18% of papers published in J. Periodontol. were not cited while less than 10% were cited ten times or more. The record for papers published in J. Periodontal Res. is slightly better, 9.5% were not cited and 12.6% were cited ten times of more in the five years following publication. In this study. there were no instances of papers that failed to be cited in the first five years achieving ten or more citations in any subsequent five year period. One class of research publication, case reports, was associated with a very low citation frequency. It appears that the influence fo case reports on subsequent research is small.
