- •To qualify for the study, the subject must have a rating of at least moderate pain on the Dental Pain Scale (DPS) and a score of at least 50 mm on the Visual Analog Scale. To be included in the moderate pain stratum, the subjects must have a rating of moderate pain in the DPS and to be included in the severe pain stratum the subjects must have a rating of severe pain in the DPS.
- •Females who are neither pregnant, as verified by a urine-based pregnancy test, nor breast-feeding.
- •Female subjects of childbearing potential and those who are post-menopausal for less than 2 years must be using a medically approved method of contraception (i.e., oral, transdermal or implanted contraceptive devices, intrauterine device, diaphragm, condom, abstinence, or surgical sterility).

排除标准
- •Presence of spontaneous toothache pain in a primary tooth. Presence of spontaneous toothache pain in more than one tooth. Presence of an open tooth cavity in a tooth adjacent to the painful tooth with the open tooth cavity.
- •Presence of concomitant oral pain due to any other condition such as: soft-tissue lesions (e.g., aphthous or traumatic ulcer, herpes labialis, acute necrotizing ulcerative gingivitis); or multiple hard-tissue (e.g., carious) lesions; pain due to other surgical procedures, injuries or dental surface sensitivity.

主要结局
Percentage of Participants With a Response
时间窗: Baseline, 5, 10, 15 and 20 minutes
Responder was defined as participant experiencing improvement in pain intensity, as exhibited by a pain score reduction on the Dental Pain Scale (DPS) from baseline of at least 1 unit for two consecutive assessments anytime between the 5 and 20-minute time points. Response in DPS scale was assigned values as 0 (None), 1 (Mild), 2 (Moderate) and 3 (Severe).
