The treatment of hypersensitive cervical abrasion cavities using ASPA cement

This study evaluated the usefulness of the alumino-silicate polyacrylate (ASPA) or glass ionomer cement in the treatment of hypersensitive cervical abrasion cavities. Various methods of treatment of hypersensitive cervical abrasion cavities have been described, and all these methods have their disadvantages. The ASPA cement was used to treat non-carious hypersensitive cervical abrasion cavities in 189 teeth from fifty-eight adult patients. The patients were followed-up for periods ranging from 6-15 months. Of the 189 treated teeth, the ASPA restoration was intact in 163 or 86.2%. Seventeen teeth or 9.0% had partial loss of the restorations and nine or 4.8% had complete loss of restorations. With regard to symptoms, 176 or 93.1% of the treated teeth were no longer sensitive to stimuli from the oral cavity following placement of the ASPA restoration. Of the fifty-eight patients, fifty-two or 89.7% were completely relieved of all symptoms. Of the remaining teeth eleven or 5.8% reported a reduction in the severity of the symptoms. Only one patient, with both restorations lost, reported no improvement. No case of pulpal death was recorded, and there was no evidence of caries at the margin of any of the restorations. The results indicate that the method is effective, and it has some distinct advantages over existing methods of treatment of these cavities.
