Objective: To study diagnoses of reported mouth opening limitations and the outcome after treatment, to better understand the symptom and the prognosis.Methods: New referrals to an Orofacial Pain & Temporomandibular Disorders (TMD) Clinic with the symptom of “jaw locking” in the referral were considered for this clinical prospective report. This referrals constituted 5.8% of all the referrals during a ten month period, and 40 patients were included. Case history, clinical examination and diagnoses were made according to the RDC/ TMD criteria. MRI and CT examinations of the temporomandibular joint were performed when indicated. Reported symptoms and clinical signs were compared for different diagnoses. The treatment was non-invasive and conservative, no patient underwent surgery. At end of treatment, the clinical examination was repeated, the primary and definite diagnoses were compared, and the improvement after treatment was evaluated.Results: The main diagnoses were disc displacement with reduction (DDwR), 23%, disc displacement without reduction (DDwoR), 30%, and myofascial pain with limited opening (wLO), 45%. General Hypermobility was significantly more frequent in the disc displacement diagnosis compared with myofascial pain (p<0.05). After treatment, the mean opening capacity was good, regardless of the diagnosis.Conclusion: A report of jaw locking is not indicative of a single diagnosis of TMD. A diagnosis based on the history and a clinical examination is generally accurate. The symptom of opening limitations responds well to conservative treatment methods.
