NCT02142543

Brief Summary

This is a prospective, randomized, blinded, placebo-controlled, crossover clinical trial to evaluate the efficacy of 2-DeNT oral topical powder in the treatment of recurrent aphthous stomatitis (RAS). To be included in the study, subjects must have had minor RAS ulcers of less than 48 hours duration. It was randomly determined which powder was used first; all subjects used both the 2-DeNT powder and the placebo powder. Subjects applied the powder twice daily and maintained a daily log recording the size of the ulcer, its erythema score, and their level of pain. The subjects continued applying the 2-DeNT powder until the ulcer was resolved.

Outcome Measures

Primary Outcomes (1)

  • Ulcer size

    Size was measured from the outside edge of the white border to the outside edge of the opposite white border. If the ulcer was oval in shape, its longest dimension was measured.

    From time of randomization until ulcer was healed, an expected average of 3 to 5 days

Secondary Outcomes (1)

  • Erythema

    From time of randomization until ulcer was healed, an expected average of 3 to 5 days

Other Outcomes (1)

  • Pain

    From time of randomization until ulcer was healed, an expected average of 3 to 5 days

Study Arms (2)

placebo

PLACEBO COMPARATOR

placebo powder containing zinc oxide, karaya gum, and yellow dye, which was added to imitate the color of the original powder, applied twice a day until the ulcer had resolved, an expected average of 3-5 days

Drug: Placebo Comparator

2-DeNT powder

EXPERIMENTAL

2-DeNT powder containing dexamethasone, diphenhydramine, tetracycline, metronidazole, nystatin, zinc oxide, and karaya gum, applied twice a day until the ulcer had resolved, applied twice a day until the ulcer had resolved, in an expected average of 3 to 5 days

  • having used corticosteroids, oral retinoids, or other immunomodulatory agents within one month of participation in the study; non-steroidal anti-inflammatory agents (e.g., aspirin, ibuprofen, etc.), acetaminophen, or oral antihistamines chronically within one month of participation in the study or any use within five days of participation in the study; topical medication (including steroids, retinoids, and anti-microbial drugs) within two weeks of participation in the study, systemic antibiotics within two weeks of participation in the study; any preparation or medication (OTC or prescription) applied to the ulcer within 48 hours of participation in the study
  • history of drug or alcohol abuse
  • having had any dental work within 2 weeks of study entry
  • having had any orthodontic or oral appliances (that could cause oral trauma) within 1 cm of the ulcer or any recollection of trauma in the area of the ulcer
