A Proposed New Index for Clinical Evaluation of Interproximal Soft Tissues: The Interdental Pressure Index

Table 4

Distribution of interproximal areas on the basis of pocket bleeding index (PBI), gingival index (GI), and clinical interdental pressure index (IPI) determinations.

	PBI+; 𝑛 (%)	PBI−; 𝑛 (%)	GI = 0 or 1; 𝑛 (%)	GI = 2 or 3; 𝑛 (%)
IPI+	11 (100)	—	2 (18)	9 (82)
IPI−	3 (21)	11 (79)	12 (86)	2 (14)
Fisher’s exact test	𝑃=0.0001		𝑃=0.001
