Trial Outcomes & Findings for OZONE_EXO: Comparative Analysis of Protocols for Dental Exactions in Patients at Risk of MRONJ: Case-control Study (NCT NCT06072404)

NCT ID: NCT06072404

Last Updated: 2025-01-09

Results Overview

The inflammatory phase is evaluated 3-5 days after tissue injury on the basis of eight parameters, measured on a 9-point scale (0-8): bleeding (spontaneously or on palpation), granulation tissue, hematoma, tissue color, incision margins, suppuration, edema, and pain. A score of 5-8 indicates a successful inflammatory phase

Participant Flow

Potential participants were identified among patients attending the "Oral Medicine with Dentistry for Fragile Patients Unit" at the Paolo Giaccone Policlinico University Hospital of Palermo from February 2018 to March 2020. Patients were approached with written and verbal information about the study.

The study recruited 117 patients (27 male and 90 female) and were randomized to treatment.

PRIMARY outcome

Timeframe: 14 days after the intervention

The proliferative phase is evaluated 14 days after tissue injury on the basis of five parameters, measured on a 6-point scale (0-5): re-epithelialization, tissue color, scar, suppuration, and pain. A score of 3-5 score indicates successful healing.

PRIMARY outcome

3 score on a scale
Standard Deviation 0
2.96 score on a scale
Standard Deviation 0.192

SECONDARY outcome

Timeframe: 6 week

The total score of the IPR scale ranges from 0 to 16:0-4 indicates poor healing; 5-10, acceptable healing; and 11-16, excellent healing The inflammatory phase carries the greatest weight in the final score because its impairment can jeopardize the entire series of biologic events leading to early wound healing.
