Trial Outcomes & Findings for Comparison Between Dexamethasone and Ibuprofen on Pain Prevention and Control Following Surgical Implant Placement (NCT NCT02763059)

NCT ID: NCT02763059

Last Updated: 2025-11-13

Results Overview

The Visual Analog Scale (VAS) is a 10-cm line with two extremes at either end: "no pain" (0) and "pain that could not be more severe" (10). Patients were asked to mark a point on the line that best represented their perceived level of pain. The marked position on the line was then measured in centimeters to provide a score between 0 and 10. * Minimum Score: 0 (No pain) * Maximum Score: 10 (Pain that could not be more severe) * Interpretation: Lower scores indicate better outcomes, representing lower levels of perceived pain. Higher scores indicate worse outcomes, representing greater levels of pain. * Unit of Measure: Scores on a scale (0-10)

PRIMARY outcome

Timeframe: 8 hours-time

The Visual Analog Scale (VAS) is a 10-cm line with two extremes at either end: "no pain" (0) and "pain that could not be more severe" (10). Patients were asked to mark a point on the line that best represented their perceived level of pain. The marked position on the line was then measured in centimeters to provide a score between 0 and 10. * Minimum Score: 0 (No pain) * Maximum Score: 10 (Pain that could not be more severe) * Interpretation: Lower scores indicate better outcomes, representing lower levels of perceived pain. Higher scores indicate worse outcomes, representing greater levels of pain. * Unit of Measure: Scores on a scale (0-10)

Timeframe: 8 hours-time

The Numerical Rating Scale (NRS-101) is a scale ranging from 0 to 100, where 0 represents "no pain" and 10(0) represents either "the worst possible pain" or "the most intense pain imaginable". * Minimum Score: 0 (No pain) * Maximum Score: 100 (Worst possible pain) * Interpretation: Lower scores indicate better outcomes, representing lower levels of perceived pain. Higher scores indicate worse outcomes, representing higher levels of perceived pain. * Unit of Measure: Scores on a scale (0-100)

SECONDARY outcome

Timeframe: 8 hours-time

The 4-point Verbal Rating Scale (VRS-4) is a verbal scale used to assess the severity of a given condition, such as pain. Patients rate their experience by selecting one of four verbal descriptors that best represents their perceived intensity, ranging from "no pain" to "severe pain." * Minimum Score: 0 (No pain) * Maximum Score: 3 (Severe pain) * Interpretation: Lower scores indicate better outcomes, representing lower levels of perceived severity. Higher scores indicate worse outcomes, representing greater levels of severity. * Unit of Measure: Scores on a scale (0-3)
