Comparative assessment of low-level laser therapy (LLLT) vs. topical application of amlexanox + lidocaine to treat recurrent aphthous ulcers (RAUs): A randomized controlled trial.

The present study aimed to assess and compare the pain perception and ulcer sizes before and after applying low-level laser therapy (LLLT) and Amlexanox + lidocaine. Twenty-six patients referring to the out-patient department of the institution and diagnosed with recurrent aphthous ulcers (RAU) were assigned to two groups to receive either LLLT or Amlexanox + lidocaine. In group 1, the patients were provided with amlexanox + lidocaine to apply topically four times daily.
