Inclusion criteria
* Ability to confirm voluntary participation and agree to all trial purposes by signing and dating the informed consent forms; * Age greater than or equal to 12 years; * One minor recurrent aphthous stomatitis with onset of symptoms within 48 hours; * Moderate to severe baseline pain, with VAS ≥ 60 mm (EVA scale 0-100 mm).
Exclusion criteria
* Any clinical findings that, in the judgment of the investigator, may interfere with the safety of research participants; * Participants diagnosed with: Behcet's disease, rheumatoid arthritis, systemic lupus erythematosus, reactive arthritis, Reiter's syndrome, Crohn's disease, ulcerative colitis); * Participants with diseases that affect healing (e.g. diabetes); * Immunocompromised participants; * Participants with aphthous herpetiform ulceration or major aphthous ulceration; * Participants using medication to treat oral ulcerations (systemic or local); * Participants who used analgesics or anti-inflammatory drugs in the 6 hours prior to the beginning of the study; * Participants who used systemic antibiotics in the 2 weeks prior to the beginning of the study; * Participants using medications that can confuse pain assessment (psychotropics, antidepressants and sedative-hypnotics), except when on a stable dose for at least 30 days prior to the screening visit, and the dose cannot be changed during the clinical trial; * Participants with current smoking habits. * Participants who are pregnant, breastfeeding or planning to get pregnant or female participants with the potential to become pregnant who are not using a reliable method of contraception; * Known hypersensitivity to the formula components used during the clinical trial; * Participants with current or medical history of cancer in the last 5 years; * Participants who participated in other research protocol in the last 12 months, unless the investigator judges that there may be a direct benefit to it.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| To assess the change in pain intensity after the first application. | 3 and 10 minutes | Difference in pain intensity 3 and 10 minutes after the first application of the medication compared to baseline, measured by the VAS scale. The VAS consists of a 100 mm line, with two end points representing 0 (no pain) and 100 (Worst Possible Pain). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| To assess the pain intensity daily after breakfast, lunch and dinner. | 7 days | Pain intensity will be evaluated daily after breakfast, lunch and dinner by the Numeric Pain Rating Scale (NPRS). The NPRS is an 11-point scale scored from 0-10 representing 0 (no pain) and 10 (Worst Possible Pain). |
| To assess the pain intensity daily at night. | 7 days | Pain intensity will be evaluated daily at night by the Numeric Pain Rating Scale (NPRS). The NPRS is an 11-point scale scored from 0-10 representing 0 (no pain) and 10 (Worst Possible Pain). |
| To assess the oral health-related quality of life | 7 days | The oral health-related quality of life will be evaluated daily at night by the adapted Oral Health Impact Profile (OHIP) questionary. |
| To assess the change in pain intensity after 3 days of treatment. | 3 days | Difference in pain intensity after 3 days of treatment compared to baseline. Pain intensity will be evaluated by the Visual Analogue Scale (VAS). The VAS consists of a 100 mm line, with two end points representing 0 (no pain) and 100 (Worst Possible Pain). |
| Percentage of participants with no pain after 3 days of treatment. | 3 days | Percentage of participants with no pain after 3 days of treatment, defined as pain intensity = 0, measured by the VAS scale. The VAS consists of a 100 mm line, with two end points representing 0 (no pain) and 100 (Worst Possible Pain). |
| Global assessment of treatment by participant after 3 days of treatment | 3 days | The global evaluation of the treatment after 3 days of treatment will be evaluated by the categorical scale of 5 points representing 0 = very bad, 1 = bad, 2 = indifferent, 3 = good and 4 = very good. |
| Percentage of participants healed after 3 days of treatment. | 3 days | Percentage of participants healed after 3 days of treatment, defined as ulcer diameter = 0 mm and pain intensity = 0, measured by the VAS scale. The VAS consists of a 100 mm line, with two end points representing 0 (no pain) and 100 (Worst Possible Pain). |
