RESUMO
PURPOSE: To evaluate the effects of topical applications of Gluma Alternate, a Gluma Desensitizer version with reduced glutaraldehyde content, Health-Dent Desensitizer and Scotchbond Multi-Purpose (SMP) on hypersensitive erosion/abrasion lesions. MATERIALS AND METHODS: 55 patients were included in the trial with at least three teeth each presenting severe sensitivity. From a total of 184 teeth, 69 were treated with Gluma Alternate, 58 with Health Dent and 51 treated SMP, serving as a control. Sensitivity was recorded as response to cold air stimulus prior to treatment, immediately after the topical application of the agents, and after 1 week, 1 month and 6 months. RESULTS: Both Gluma Alternate and SMP showed significant reduction in sensitivity between pre- and postoperative pain scores (P < 0.05). The post-treatment sensitivity scores (0 and 1) were no different between 1 week and 6 months. In the Health-Dent group only 10 of the 58 teeth showed sensitivity reduction. For this reason the remaining 48 teeth received a "rescue treatment" with Gluma Desensitizer. At the end of the 6-month observation time, all teeth treated with Gluma Alternate, Gluma Desensitizer, and SMP showed no or very little dentin sensitivity.

The aim of this clinical trial was to investigate the effects of topical applications of Gluma 3 Primer or Gluma 2000 conditioning solutions on hypersensitive erosion/abrasion lesions. Thirty-four patients were included in the trial with at least two teeth each presenting severe sensitivity. From a total of 116 teeth, 40 were treated with Gluma 3 Primer, 42 with Gluma 2000 Conditioner and 34 served as the control. Sensitivity was recorded as response to tactile and cold air stimuli prior to treatment as baseline, immediately after the topical application of the agents, after 1 week, 1 month and 6 months. Both Gluma groups showed a highly significant reduction in sensitivity between baseline and postoperative pain scores (P < 0.05) and between the postoperative and the 1-week responses (P < 0.05). The sensitivity scores were not different between 1 week and 6 months. In the control group, no pain reduction was registered between baseline and up to 1-month recall. After 6 months, however, the sensitivity was spontaneously slightly reduced. At the end of the 6-month observation time, 29 Gluma and 31 Gluma 2000 treated teeth no longer showed dentin sensitivity.
