Brief summary

The purpose of this study is to compare the efficacy of laser photobiomodulation and Magic Mouthwash for treatment of pain in pediatric patients with aphthous ulcers , to assess how photobiomodulation influences the rate of healing of aphthous ulcers in pediatric patients and to measure changes in pain levels reported by pediatric patients undergoing photobiomodulation treatment for aphthous ulcers.

Interventions

patients will receive PBM therapy using the Biolase Epic pro laser. An average power of 0.6w (peak power = 80w, rep. rate= 20Hz). Each aphthous ulcer will be irradiated one time for a total of 30 seconds via continuous wave.

DRUGMaalox plus Benadryl

1:1 mixture of Maalox and Benadryl will be applied to the ulcer as needed for pain. Applications typically will be applied before eating to form a dissolvable oral band-aid that lasts for up to 30 minutes. 10 milliliters of 1:1 Maalox: Benadryl solution will be provided to the family. During the presenting appointment, the patient/family will be shown how to use the 1:1 Maalox: Benadryl solution. It will be applied topically with no rinsing needed.

Design outcomes

Primary

MeasureTime frameDescription
Change in Quality of life as assessed by questionnaire (Likert scale)Baseline, immediately after treatment(about 5 minutes), 24 hours after treatmentThis is a 6 item questionnaire and each is scored from 1-5, maximum score of 30,higher number indicating better outcome
Pain as assessed by how frequently patient complains of pain (Likert scale)upto 24 hours after treatment
Pain as assessed by number of participants who are using any over-the-counter or prescription medications, topical treatments, or oral rinses to treat aphthous ulcer painupto 24 hours after treatment

Secondary

MeasureTime frameDescription
Change in lesion size as an indication of healing as assessed by clinical intraoral images of the aphthous ulcer and measuring toolpre-treatment and immediately post-treatment(about 5 minutes)
Change in pain as assessed by a Visual Analogue Scale (VAS) for control groupBaseline, 24 hours after treatmentPain level is scored from 0(no pain) to 10(worst pain)
Pain as assessed by a Visual Analogue Scale (VAS) for experimental groupBaseline, immediately after PBM(about 5 minutes), 24 hours after treatmentPain level is scored from 0(no pain) to 10(worst pain)
