Introduction The prevalence of oral piercings in the UK is increasing. Consequently, the dental profession is encountering an increasing number of complications associated with piercings. Providing patient preventative advice regarding piercing complications is important, however the level of advice offered by UK dentists is currently unknown. Aims The aim of this survey was to establish the current knowledge, attitudes and behaviours of dentists regarding advice provided to patients with oral piercings. Methods A questionnaire was sent to 200 dentists across Wales with questions regarding perceived confidence in providing advice, type of advice provided, the sources dentists use to acquire knowledge and the perceived need for further professional information. Results Fifty-three dentists responded. Only 24.5% were very confident discussing piercing complications. The advice provided varied markedly, with the majority (73.6%) reporting they had acquired knowledge through experience alone. Only one dentist reported providing written information and 83% responded that they would like to have access to printed information directed at patients. Conclusions The results of this survey suggest that dental professionals are not fully confident discussing risks and preventative advice with patients. To address this, patient information leaflets have been developed to encourage dentists to discuss complications associated with oral piercings with patients.
