Abstract
Enormous advances have been made over the past decade concerning the proper use of statistical techniques in reporting periodontal research. However, numerous articles still appear which use inappropriate or less than optimal statistical methods. This paper describes the most common problems encountered in a recent review of the literature, and presents suggestions which will hopefully improve the quality of statistical information reported in future research articles.
