Abstract : An investigation was made to (1) evaluate the effect of tooth selection on periodontal indices and (2) compare two periodontal examination systems now in use. Employing data secured from periodontal examination of all teeth in 117 males, aged 17 to 24 years, the highest coefficient of correlation found was between the mean for all teeth and the mean of the teeth employed in the Ramfjord system (P.D.I.) (.944). The Periodontal Screening System (G.P.I.) and the P.D.I. examination system were compared by scoring periodontal status on a segmented basis where the highest score of any tooth in a segment was used as the score for the segment. The coefficient of correlation for the G.P.I. system was .961 compared to .910 for the P.D.I. system. The G.P.I. system was more effective in classifying periodontal status on a segmented basis.
