Studies suggest that despite improvement in dental health the overall level of dental fear and anxiety in population has remained relatively consistent over recent decades. The origins of dental fear and anxiety result from a combination of both cultural factors (traditions, myths and beliefs) as well as psychological factors. However less is known about the influence of oral health beliefs on feelings and behaviours related to health professional care, in particular dental fear and anxiety
This review aimed to critically appraise the evidence on the relationship of oral health beliefs with dental fear and anxiety in distinct patient groups.
Searches were conducted in the Cochrane, Embase, Portal BVS, Clinical Trials, Ovid, OpenGrey, PubMed, Scopus, and Web of Science databases. There were no limits on language or date of publication. Case-control, cohort, and cross-sectional studies assessing the association between negative health beliefs and dental fear/anxiety were considered.
Two reviewers independently selected the studies, extracted data and assessed risk of bias. The Newcastle Ottawa Scale for the relevant study design was used to assess risk of bias. Random effects meta-analysis of mean differences of dental beliefs scores between dental fear/anxiety and control groups, and the correlation of dental beliefs with dental fear and anxiety measures were conducted for studies with low or unclear/moderate risk of bias.
- 10 studies involving a total of 5257 patients were included.
- 4 studies were considered to be at high risk of bias, 6 at unclear or moderate risk of bias.
- 7 different dental fear and anxiety measures were used and 4 different methods to assess dental beliefs.
- 6 studies contributed to the meta-analysis.
- The standardised mean difference of dental beliefs effects was higher in patients with dental fear and anxiety compared to controls = 1.20 (95%CI; 0.27-2.14) [ 3 studies,1074 patients].
- A moderate positive correlation was observed between dental beliefs and dental fear measures; r = 0.54 (95%CI; 0.47-0.60) P < 0.001.
The authors concluded: –
Based on these results, the presence of negative health beliefs is directly related to the increase of dental fear and anxiety; however, these findings are supported in studies with unclear/moderate risk of bias.
The authors have searched a broad range of databases to identify relevant papers and used standard methodological approaches to assess risk of bias. However, none of the included studies were considered to be at low risk of bias, with most being considered to be at risk in relation to selection bias and exposure and outcome measurement. Consequently while the findings suggest that patients with negative health beliefs are more likely to suffer with dental fear and anxiety this should be interpreted cautiously.
