The Toronto Automated Periodontal Probe allows simultaneous measurements of gingival attachment level and probing velocity. The efficacy of probing velocity in measuring the integrity of the dento-gingival junction was studied and compared with loss of gingival attachment level, gingival inflammation, tooth mobility and gingival crevicular fluid collagenolytic activity. The gingiva around the maxillary and mandibular incisor teeth of 2 monkeys were first brought to clinical health by daily prophylaxis. Baseline measurements were made and inflammation was then induced around the maxillary incisors by withdrawing plaque control and by placing silk ligatures subgingivally. The mandibular incisors served as controls. After 10 weeks, the ligatures were removed and the teeth scaled and polished daily for 1 week. The plaque index and gingival index reached maximum values within 1 week; crevicular fluid flow was significantly increased at 1 and 3 weeks but mobility did not change significantly. There was progressive loss of the gingival attachment level, which peaked at 10 weeks on experimental teeth; there was no significant loss on control teeth. Probing velocity around experimental teeth exhibited large and significant increases above controls between 1 and 3 weeks, coinciding with the largest weekly losses of the gingival attachment level. Thus probing velocity may be a useful clinical method for the ancillary measurement of early loss of the gingival attachment level. It can also detect biophysical changes in the dento-gingival junction of progressive inflammatory lesions.
