To determine the circumstances in which oral health promotion (OHP) in General Dental Practice is at its most effective, a systematic review was conducted to identify, critically appraise and synthesize the available evidence. The research question was: Is oral health promotion within dental practice effective and how can its effects be optimized? Systematic searches of 20 online resources (including Ovid Medline and Embase) were conducted. A call for evidence was also issued, and citation lists of other relevant systematic reviews were included. All studies published since 1994 which were set in the context of general dental practice and investigated promoting good oral health in adult or child patients were considered. 44 studies reported in 52 papers were included in the review. The evidence was heterogeneous and the quality of reporting was variable. Results showed that oral health promotion based on behavioural and psychological models was effective for improving oral health. Verbal advice affected knowledge and reported behaviour, written advice promoted oral health knowledge. There was moderate evidence that the attributes of the 'sender' of an oral health promotion message influenced its effectiveness. Many barriers and facilitators were shown to influence the effectiveness of OHP in dental practice. The results of this review suggest that the psychology of behaviour change is the key to oral health promotion and greater emphasis on teaching oral health professionals about health psychology would make oral health promotion in the dental surgery more effective.

Objectives The objective of this study was to systematically review the evidence regarding the use of motivational interviewing in the context of general dental practice, in order that practitioners can decide whether it might be an important skill to develop within their practices.Data sources The results reported in this study form part of a larger systematic review which sought to identify whether oral health promotion within dental practice is effective and how its effects can be optimised. Here, we focus on the papers describing motivational interviewing in dental practice published since 1994. The systematic review included searches of 20 online resources (including Ovid Medline and Embase).Data selection Papers which were not about oral health promotion and did not apply the behavioural and psychological theories, which underpin motivational interviewing, were excluded.Data synthesis This review included eight papers all of which were considered to be of robust quality, in terms of their research methods and seven of which were considered to offer externally valid findings. Five described randomised controlled trials and all of these RCTs demonstrated that interventions including motivational interviewing had a positive effect on oral health and health behaviour.Conclusions This review shows that the motivational interviewing technique, which is based on the concept of autonomy support, has potential for helping patients with poor oral health. Training in motivational interviewing for dental personnel could be a very useful addition to the skill set of practitioners and dental teams.
