multiple studies have demonstrated the benefits of providing routine HIV screening in the A&E environment to be both feasible and effective. We are aware of the oral manifestations which are common in HIVpositive patients, such as candidiasis, RAS, hairy tongue and periodontal disease.In providing routine HIV screens as a form of investigation, we can collectively increase the number of undiagnosed positive patients which would in-turn not only aid in the appropriate management of these patients, but also reduce the risk of HIV transmission to other members of the population. I feel that all clinicians should consider the deduction of STIs, particularly HIV, when investigating and thus diagnosing oral diseases.
