Conservative Treatment of Cervical Sensitivity M. Balanko, D.M.D.* R.E. Jordan, D.D.S., M.D.S.' A highly effective, long-lasting treatment of cervical sensitivity is presented.
A
lthough cervical sensitivityassociatedwith gingival recession may occur at any age, it is most frequently encountered in the geriatric dentition particularly after extensive bone loss, gingival recession, and/ or periodontal surgery. The exposure of cementa1 root surfaces is usually associated with extreme tooth pain on brushing or temperature changes. Cervical sensitivity may be eliminated on a long-term basis using either All Bond (Bisco Inc., Itasca, IL) or Tenure Bond (Den-Mat Corp., Santa Maria, CA) with the following technique.
METHOD Figure 1 shows a n extremely sensitive maxillary left canine in an adult patient. The gingival tissue is retracted using a proper clamp (Ivory212 SA, Columbus Dental, St. Louis, MO) (Fig.2).Gingival retraction cord may alternately be used. After a thorough flour of pumice prophylaxis, the cervical area is washed with water and warm air dried. A dilute phosphoric acid gel (either Etch N Seal [Den-Mat] or All Etch [Bisco]) is injected to cover the cervical area for 15 to 20 seconds (Fig. 3). The area is then washed with water and carefully warm air dried (Fig. 4). Several coats of either All Bond Mixed Primer (Bisco) or Tenure Bond (DenMat) are applied to the cervical area (Fig. 5) followed by warm air drying (Fig. 6). The cervical area should appear highly glossy and reflective.A layer of bond resin (either All Bond Dentin Enamel Bond [Bisco] or Visar Seal [Den-Mat]is applied to the cervical area on a finetipped brush followed by visible light curing. Finally a layer of filled glaze (either Bisco Glaze [Bisco] or Compguard [Den-Mat])is applied using a fine-tipped soft brush (Fig. 7) and visible light cured. Figure 8 shows the bond resin desensitized cervical region. The treatment as described is highly effective and long lasting.
