Effect of Amalgambond on cervical sensitivity.
OBJECTIVE
To evaluate in vivo the feasibility of utilizing Amalgambond adhesive agent alone for the treatment of cervical sensitivity on teeth that did not require a restoration.


METHODS
Nineteen subjects were selected from a group of patients reporting sensitivity at the cervical region of anterior or posterior teeth. The degree of sensitivity was determined by tactile sense (scraping an explorer over the surface area) or "fluid-shift" sensitivity determined by an air-blast from a syringe for 5 seconds. Patient reactions to stimuli were qualified as : (1) none; (2) slight; (3) moderate; and (4) severe. Only patients with at least two teeth experiencing moderate or severe sensitivity were used. Each of the patients had at least one sensitive tooth treated with Amalgambond and at least one untreated sensitive tooth to act as control. Results were recorded at 24 hours, 7 days, 1 and 6 months.


RESULTS
At 6 months, 18 of 19 treated teeth recalled showed decreased sensitivity with 15 showing no sensitivity, and only one remained as sensitive as at baseline. All control teeth remained unchanged from original sensitivity ratings. The teeth with cervical sensitivity treated with Amalgambond adhesive alone had a high probability of decrease or complete loss of sensitivity immediately and the decrease was sustained for at least 6 months (P<0.001).
