Technic for treating cervical sensitivity.

PURPOSE: 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. MATERIALS AND 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).

Self-applied treatments in the management of dentine hypersensitivity.

A summary of the research on the different self-applied treatments for hypersensitive dentine provides some support for several agents but invalidates others. This is true for toothpastes, mouthwashes and gels. Direct comparison of studies is difficult because the materials and methods used are different. In addition, the size of patient groups, and methods of stimulation and assessment of the evoked pain reaction are different. Therefore our concept of the efficacy of self-applied treatment is not so much based on a homogeneous pool of data, but rather on a collection of individual studies. If we subtract from these data sets those based on obviously older ways of evaluating efficacy, we are left with surprisingly few studies that properly assess the efficacy of compounds suited to self-applied treatment. Therefore, guidelines should be established for testing such compounds, and publication of the data sets should depend on proper use of such designs. Stimuli, design and pain assessment should be standardized. In addition, patient recruitment could be defined better in relation to criteria for inclusion. Another area of concern is the pretreatment history of the hypersensitive teeth, because some teeth will become hypersensitive during the observation period, whilst others, which were hypersensitive, will spontaneously become insensitive. Therefore one should know the rate of spontaneous change in tooth sensitivity levels in each patient, in order not to assign treatment effects to teeth that would have lost their sensitivity anyway.
