An Italian version (OBC\u2010It) has been released recently. Anxiety and oral behaviours are known to be associated in individuals with oro\u2010facial pain due to temporomandibular disorders (TMD).

Group B received instructions about the OBC\u2010It, while Group A did not. After 2\u00a0weeks, both groups filled in the OBC\u2010It again.
