NRS: numerical rating scale to assess the impact of TMJ pain on the patients abilities to perform daily activities and on the quality of their life on a 0–10 NRS where 0 corresponded to “no impact of TMJ pain on daily activities/quality of life” and 10 corresponded to “maximum impact of the TMJ pain on daily activities/quality of life.” A NRS was also used to assess the TMJ pain intensity where 0 corresponded to “no pain” and 10 to “worst imaginable pain.”
