  2. Study First Submitted
  • Stopped: an ongoing trial was terminated, suspended or withdrawn.

  • Minor: routine progress and housekeeping, such as sites added or enrollment closed.
The goal of this clinical trial is to determine whether strontium-doped bioactive glass-ceramic (SBGC)-filled dentine adhesive is effective in relieving dentine hypersensitivity. The main question it aims to answer is: Is SBGC-filled dentine adhesive more effective in reducing dentine hypersensitivity than non-SBGC-filled dentine adhesive? Researchers will compare SBGC-filled dentine adhesive to a dentine adhesive to see if SBGC-filled dentine adhesive is more effective at relieving dentine hypersensitivity. Participants will receive a single application of either SBGC-filled dentine adhesive (intervention group) or dentine adhesive (control group) on the root surfaces of teeth presenting with pain subject to an air-blast test. The degree of pain will be assessed using a Sensitivity Score at baseline, immediately after application of either the intervention dentine adhesive or control dentine adhesive. The participants will visit the clinic at 1 month, 3 months and 6 months for re-assessment of the severity of dentine hypersensitivity.
