Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

20 years to 64 years (ADULT)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

Initial dose:

  • 20 to 64 years
  • Patients with undergoing mandibular impacted third molar tooth extraction accompanied by lateral bone removal and crown cutting
  • Patients with pain that meets both of the following criteria
  • Pain intensity (4-categorical): "moderate pain" or "severe pain"
  • Pain intensity (VAS): 45.0 mm or more

Additional dose:

  • Patients with pain that corresponds to "4. Agree" or "5. Strongly agree" as the answer to the "question about the pain intensity" during the period from 5 hours to 12 hours post-initial dose of the study drug

Exclusion Criteria:

  • Patients with acute inflammatory findings in the oral cavity necessitating treatment
  • Patients who are scheduled to receive general anesthesia and analgesics in the process of the eligible tooth extraction

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Efficacy Rate (Percentage) of Patient's Impression
Time Frame: 2 hours post-additional dose

Patient's impression was assessed by self-report and was entered in the patient diary, based on the following categories: "Excellent", " Good", "Fair" and "Poor".

Efficacy rate was calculated from the following formula, "The number of participants assessed as Excellent or Good" over "total participants" multiplied by 100.
2 hours post-additional dose

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Number of Participants in Each Pain Intensity (PI) With 4 Categories
Time Frame: 2 hours after additional dose
Pain intensity was entered in the patient diary on the following categories: "No pain", "Mild pain", "Moderate pain" and "Severe pain".
2 hours after additional dose
Pain Intensity Measured by Visual Analog Scale (VAS)
Time Frame: 2 hours post-additional dose
The Pain intensity was recorded on the 100 mm VAS in the patient diary, where 0 mm=no pain, 100 mm=unbearable maximal pain.
2 hours post-additional dose
Differences in Pain Intensity (PI) Measured by VAS Among Participants
Time Frame: Pre-additional dose (baseline) and 2 hours post-additional dose
The differences in PI were obtained by subtracting the PI at each time point from the Baseline PI score.
Pre-additional dose (baseline) and 2 hours post-additional dose

Primary Completion (ACTUAL)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
