Oral amyloidosis: two unusual case presentations.

Two cases of oral amyloidosis are reported. In each case there were unusual oral manifestations. In the first case the patient's only complaints were of recurrent swelling of the submandibular glands and xerostomia. The diagnosis of amyloidosis was determined from a labial salivary gland biopsy. In the second case an enlarged tongue had produced displacement of the teeth, causing malocclusion. The resulting difficulty in chewing stimulated the patient to seek advice. In each case the diagnosis was confirmed by electron microscopy, Congo red staining, and serum and urine electrophoresis.

Three year follow-up TMJ patients: success rates and silent periods.

A telephone survey to assess treatment success was conducted 2-3 years after treatment of patients suffering from TMJ syndrome. Pre-treatment silent period durations were compared among groups of patients determined by their response to the telephone survey. The short-term (immediately post-treatment) improvement rate was 81%. Some 35% of patients were completely cured. There was no statistically significant difference in mean silent period duration among the groups of patients that achieved complete, partial or no relief of symptoms. The long-term (2-3 years after treatment) persistence of improvement rate was 72%. There was also no statistical difference in the mean silent period duration between those patients who had experienced persistence of success and those who reported either no relief or relapse of symptoms.

The effect of voluntary activity on the masseteric silent period duration.

This study examined both TMJ and normal groups for any changes in the masseteric silent period with variation of the subjects' occlusal force. An analog meter was used to give each subject feedback on how hard the teeth were clenched together. Five silent periods were elicited at each of the four levels of occlusal force from 40% to 100% of maximum force. Results showed a small decrease in silent period duration for both groups when occlusal force was increased.

The variability of EMG silent periods in TMJ patients.

The variability of the EMG silent period in jaw closing muscles of TMJ dysfunction patients was examined. Considerable within-subject variability was found in the duration of the silent period. This variability increased with symptom severity. The authors recommend that multiple measurements be averaged to obtain a more accurate estimate of the silent period duration.

A public education program in self-examination for orofacial cancer.

Instruction in self-examination for early signs of orofacial cancer was given to over 450 persons attending a large county fair in western New York State. Participants received one-on-one instruction from dentists or specially trained dental hygienists according to a protocol designed to detect abnormalities of the oral cavity, cervical lymph nodes, and major salivary glands, as well as facial skin cancers. This method of personal instruction was judged feasible for large-scale application.

TMJ symptom severity and EMG silent periods.

The hypotheses that latency or duration of the EMG silent period evoked by a tap to the chin during a maximal clench would be more prolonged in more severe TMJ patients were tested. The mean latency did not, and the mean duration did, increase significantly with increased severity of TMJ dysfunction.
