Otalgia and aversive symptoms in temporomandibular disorders.

The term Costen's syndrome has been used in the dentomedical literature to describe a constellation of craniofacial symptoms. Since some of the same complaints have been reported in patients with "generalized" psychological distress, symptoms associated with the syndrome may not be useful in differential diagnosis of temporomandibular disorders. The present study investigated whether some somatic complaints, particularly tinnitus and dizziness, were pathognomonic in patients with chronic temporomandibular pain. Illness behavior and personality factors were studied for possible interrelationships with these symptoms. Factor analysis revealed that tinnitus and dizziness loaded on separate factors. Tinnitus loaded with nasal stuffiness, tearing, and itching of the eyelids and nose, while dizziness loaded with complaints of altered taste and smell and blurred vision. Neither was consistently related to measures of pain or to indices of illness behavior or somatic focus.

Interexaminer comparison of bone scintigraphy and panoramic radiography of temporomandibular joints: correlation with signs and symptoms.

Panoramic radiographs of the temporomandibular joints of patients with orofacial pain were examined for evidence of pathology by three different groups of four dental specialists and by a group of four general dentists. Bone scans of the same joints were used as the "gold standard" for identification of disorder and indicated a low rate of correct readings by the four professional groups. When the symptomatic side of the complaint was used as the gold standard, there was no statistically significant association with the bone scan observations. Comparative analysis of other patient symptoms showed little agreement with panoramic radiographs and scintigraphs. Reliability estimates may be highly variable, even among clinical experts. These results show that neither radiologic technique would be definitive for diagnosis of TM disorders.

Management of the isolated deformed dentinoalveolar complex by subepithelial graft and resin-bonded fixed partial denture.

Two cases in which subepithelial connective tissue grafts were used as adjuncts to definitive prosthetic reconstruction have been presented. The method for managing the deformed dentinoalveolar complex in the anterior portion of the mouth was discussed. The improved appearance coupled with the resin-bonded fixed partial denture warrant the consideration of the subepithelial graft in selected cases.

Reinforced matrices for pin-amalgam restorations reduce microleakage.

The considerable decrease in microkeakage in the compound-reinforced restorations may be due to the tighter fit of the matrix band at the gingival wall of the preparation, which allows better condensation and marginal sealing of the restoration. The compound prevents lateral migration of the band during condensation pressures.
