Abstract [en]

STUDY DESIGN: Prospective cohort study OBJECTIVE.: To evaluate the course of orofacial pain and jaw disability in relation to neck pain, neck disability and psychosocial factors at the acute stage and the chronic stage after whiplash trauma.Summary of Background Data Many individuals report chronic pain in the orofacial region after whiplash trauma. The possible association between whiplash trauma and orofacial pain is debated. Prospective studies are therefore needed to evaluate the development of orofacial pain after whiplash trauma.

METHODS: Within one month following a whiplash trauma, 176 cases were examined and compared to 116 controls with questionnaires concerning neck and jaw pain and related disability, non-specific physical symptoms and depression. At the 2-year follow-up, 119 cases (68%) and 104 controls (90%) were re-examined.

RESULTS: Compared to controls, cases reported more jaw and neck pain, both at baseline and follow-up. A majority (68%) of cases with pain in the jaw region in the acute stage also reported jaw pain at the follow-up. The intensity of jaw and neck pain was correlated both at baseline and follow-up. Both neck pain and jaw pain was correlated to non-specific physical symptoms and to depression.

CONCLUSION: Orofacial pain and jaw disability related to neck pain is often present already at the acute stage after whiplash trauma and persist into the chronic stage for most individuals. Assessment following whiplash trauma should therefore include both the neck and the orofacial regions. More studies are needed to further evaluate risk factors for development of orofacial pain after whiplash trauma.
