Recurrent aphthous ulcer

Last edited: 4/15/2026

Overview

Recurrent aphthous ulcers (RAU) are common, painful oral mucosal lesions with no definitive cure, typically managed to reduce pain and promote healing. 1

Diagnosis

  • Clinical presentation characterized by recurrent, small, shallow ulcers in the mouth.
  • No specific diagnostic tests; diagnosis is clinical.
  • Grading systems often assess ulcer size, frequency, and duration, though standardized scales vary 1.
  • Management

  • First-line treatments: Topical corticosteroids, antimicrobial mouthwashes (e.g., chlorhexidine).
  • Adjunctive treatments:
  • - Bioadhesive devices containing 2-octyl cyanoacrylate applied by healthcare providers or self-administered, showing significant pain reduction and accelerated healing 1. - Systemic retinoids like etretinate in severe cases, particularly in non-childbearing individuals, warranting further assessment 2.

    Special Populations

  • Pregnancy: Systemic retinoids such as etretinate are contraindicated due to teratogenic risks 2.
  • Pediatrics: Limited specific guidance; treatments generally similar to adults but with caution regarding systemic agents 1.
  • Elderly: No specific considerations noted; management aligns with general guidelines 1.
  • Comorbidities: No specific recommendations provided in abstracts; tailored management based on underlying conditions is advised 12.
  • Key Recommendations

  • Consider the use of bioadhesive devices containing 2-octyl cyanoacrylate for pain reduction and accelerated healing in RAU management (Evidence: Strong 1).
  • Evaluate systemic retinoids like etretinate in severe cases of RAU among non-childbearing individuals, acknowledging potential benefits despite risks (Evidence: Moderate 2).
  • Prioritize topical corticosteroids and antimicrobial mouthwashes as initial treatment options for RAU (Evidence: Expert opinion 1).
