Does anxiety have an impact on temporomandibular disorders? A study in a Turkish sample by using specific questionnaires

Objective The aim of the study is to verify the impact of anxiety on temporomandibular disorders (TMD) by using specific questionnaires in a Turkish sample. Methods This survey was conducted on 292 patients with a mean age of 38.59 +/- 10.38 using Helkimo index, Oral Health Impact Profile (OHIP-14), and State Trait Anxiety Inventory (STAI). Spearman Correlation and Fisher Freeman Halton analyses were used for the statistical analysis. Results There was no statistically significant difference between the Helkimo anamnestic dysfunction (HAD) levels in terms of OHIP-14 total scores or STAI state scores. There was, however, a statistically positive correlation between STAI state and OHIP-14 total values at 18.4%, a positive correlation between the STAI trait and OHIP-14 total values at 29.8%. Conclusion No significant correlation was observed between OHIP-14 total scores, STAI state scores, and HAD levels. Therefore, this study did not find a significant relationship between TMDs and anxiety.
