Dental anxiety was assessed using the CORAH-Modified Dental Anxiety Scale (CORAH-MDAS) preoperatively, immediately postoperatively, and at 1 and 2 weeks. Perceived stress was evaluated using the 10-item Perceived Stress Scale (PSS-10) at baseline and 1 month.

Further, these factors may have a causal relationship with pain. Systemic conditions such as arthritides, autoimmune disorders, anemias, chronic infections, thyroid disorders, and medication- induced myalgia seem to have the most impact.
