Sense of coherence and dental fear/dental anxiety: A systematic review and meta-analysis.

AIM The aim of this systematic review and meta-analysis was to evaluate the association between sense of coherence (SOC) and dental fear/dental anxiety. METHODS Computerized searches were performed in six databases. Gray literature and manual searches were also conducted. Study selection, risk of bias assessment, and meta-analyses were performed. The results of meta-analyses were reported in odds ratio (OR), mean difference (MD), and confidence interval (CI). RESULTS After removing duplicates, 131 references were retrieved and the full texts of 12 were evaluated. Nine references met the eligibility criteria and were included. The results of meta-analyses demonstrated that individuals with a weaker SOC had a score in the dental anxiety/dental fear scale 6.04 times higher than individuals with a stronger SOC (OR = 6.04, CI = 2.62-13.91). Individuals with no dental anxiety/dental fear had a mean score of the SOC scale higher than individuals with dental anxiety/dental fear (MD = 5.39, CI = 2.21-8.56). Sensitivity analysis demonstrated that the result of a higher mean score of the SOC scale among individuals with no dental anxiety/dental fear remained (MD = 7.38, CI = 3.79-10.98). Risk of bias ranged from low to high. The certainty of evidence was very low. CONCLUSION Individuals with stronger SOC have lower levels of dental fear/dental anxiety.
