Aphthous ulcers (recurrent).

INTRODUCTION

Most people with recurrent aphthous ulcers develop a few ulcers less than 10 mm in diameter that heal after 7 to 10 days without scarring. The causes are unknown but local physical trauma may trigger ulcers in susceptible people. In 10% of sufferers, lesions are more than 10 mm in diameter and can cause scarring.

METHODS AND OUTCOMES

We conducted a systematic review and aimed to answer the following clinical question: What are the effects of selected topical treatments for recurrent idiopathic aphthous ulcers? We searched: Medline, Embase, The Cochrane Library, and other important databases up to December 2013 (Clinical Evidence reviews are updated periodically; please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

RESULTS

We found nine studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

CONCLUSIONS

In this systematic review we present information relating to the effectiveness and safety of the following interventions: analgesics (local), corticosteroids (topical), tetracycline antibiotic mouthwash, and topical antiseptic agents (chlorhexidine and similar agents).
