Not Applicable

Completed

• Conditions: Diagnoses Disease; Periodontitis
• Interventions: Device: Florida Probe Straight Tip Probe; Device: Ball Tip Probe

• Registration Number: NCT03690479
• Lead Sponsor: University of Florida

Brief Summary

Patient perception of pain on periodontal probing using a controlled-force, electronic probe was not significantly affected by the use of a modified (ball-end) probe tip design except for in the maxilla, where a standard straight probe tip appeared to be more comfortable for patients.

Detailed Description

Recordings of periodontal probing pocket depth (PPD) and probing attachment level (PAL) are utilized in diagnosis of periodontal disease and monitoring of disease progression. Manual probing presents reproducibility and accuracy issues based on features such as probe tip design, force applied by the operator and inflammatory status of the periodontal tissues. Evidence from the literature suggests that some patients may determine periodontal probing to be a painful experience.

The aims of this study are to evaluate the suitability of a new titanium probe tip for periodontal probing, and to evaluate pain on periodontal probing, in comparison to the existing probe tip used in the Florida Probe® system.

The study will be a randomized, blinded, split-mouth controlled trial. Twenty (20) consecutive patients meeting the inclusion criteria will be selected to undergo full-mouth periodontal probing. One half (upper or lower jaw) of the mouth will be probed using the current, standard probe tip; the opposing jaw will be probed using the new trial tip. At a second visit (within 2 weeks), prior to treatment, the mouth will be probed once again, alternating the jaws from the first visit.

On each occasion, patients will report on pain on probing utilizing two ungraded 100mm horizontal visual analogue scales (VAS) representing upper and lower jaws of the mouth.

Periodontal probing depth measurements will be compared to assess the reproducibility of the two probe tips.

Mean VAS values and standard deviations will be calculated for the test and control groups. Data analysis will be conducted using a non-parametric statistical model (Mann-Whitney U Test).

Inclusion criteria:

* Adult patients: age greater than 18 years.

* At least 4 tooth sites with periodontal probing pocket depth (PPD) greater or equal to 4mm.

Exclusion criteria:

- Patients using ongoing daily chronic analgesic medications (NSAIDs etc) for over 3 months.

Arm && Interventions

Group	Intervention	Description
Florida Probe Straight Tip Probe	Florida Probe Straight Tip Probe	One half (upper or lower jaw) of the mouth will be probed using the current, standard probe tip (straight-end probe, 0.45mm diameter).
Ball Tip Probe	Ball Tip Probe	One half (upper or lower jaw) of the mouth will be probed using the new trial tip (ball-end probe, 0.6mm diameter).

Primary Outcome Measures

Name	Time	Method
VAS (visual analogue scale) value 0-100mm	2 weeks	Patients will report on pain on probing utilizing two ungraded 100mm horizontal visual analogue scales (VAS): line with values from 0-100, where 0 is no pain and 100 is the worst possible pain, representing upper and lower jaws of the mouth.; Periodontal probing depth measurements will be compared to assess the reproducibility of the two probe tips.
