A Comparison Between the Repeatability of Probing Pocket Depths Achieved With Manual and Automated Periodontal Probes

Measuring the clinical attachment loss using a periodontal probe is the benchmark by which attachment loss is diagnosed in periodontal disease. The accuracy and reproducibility of the probing measurements is an essential part of diagnosis, treatment planning and assessment of the treatment outcome. There are inherent errors associated with probing that have been identified in the literature. These relate to the operator technique, the probe used and the state of inflammation of the periodontal pocket/crevice.

The aim of this study is to compare the reproducibility of probing measurements using a probe tip with millimeter markings up to 15mm in the Florida probe ® handpiece. This tip will be used to allow conventional clinical measurements to be recorded at the same time as the electronic recordings on the Florida probe ®. The examiner would take the manual probe measurement and be blind to the electronic reading taken. The sites under question will have a second measurement recorded to allow assessment of the repeatability of the recordings. Therefore, from 2 probing passes 4 measurements would be obtained 2 manual and 2 electronic readings.

Inclusion criteria

• Age 18 and over

Exclusion criteria

• Any medical condition that would exclude them from having the measurements taken
• Any medical problem that would make participation difficult
• If they do not have sufficient sites where probing depths are required.
