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

Abstract: The interdental pressure index (IPI) is introduced to specifically evaluate clinical interproximal-tissue conditions and assess the effect of interproximal hygiene stimulation. This index scores clinical responses of periodontal tissues to the apical pressure of a horizontally placed periodontal probe. It is negative when gingival tissues are firm, bleeding-free, and slightly ischemic by the stimulation; otherwise it is positive. The clinical validation showed high intraoperator agreement (0.92; 95% CI: 0.82–0… Show more

“…The pressure applied by a horizontal probe in the interdental area should be firm and continuous until reaching maximum compression with minimal discomfort to the patient. A Visual Analogical Scale (VAS) was used to estimate the patient’s discomfort perception correlated to interproximal pressure (0 = no pain, 10 = unbearable pain) [ 11 ].The force ranged between 100 and 200 cN (0.40–0.80 gram force), and 80% of subjects assigned a VAS score ≤ 3 to their discomfort. From this observation, it can be assumed that a correct IDB classification recording force should induce minimal patient discomfort.…”

“…A 95% agreement on criteria for pocket depth and CAL was obtained. A visual analog scale (VAS) was used to estimate the correlation between the patient's discomfort perception and the interproximal pressure (0 = no pain, 10 = unbearable pain) [39]. The pressure used to place the IDB was approximately 0.20-0.40 g-force, and 78% of participants were assigned a VAS score of ≤1.…”
