A novel clinical protocol for dentin hypersensitivity management based on regenerative dental gel associated with calcium: A case study in a patient with periodontal disease

Introduction: Dentin hypersensitivity (DH) is defined as pain caused by dentin exposure in response to various stimuli. Patients with periodontal disease (PD) frequently report DH due to root surface exposure or after periodontal treatment. Bioactive agents derived from calcium and/or silicon-based systems, such as REFIX technology, have been used to promote tooth regeneration, with focus on tooth sensitivity treatment. Case Report: Based on this, the efficacy of REFIX gel combined with calcium on the treatment of a DH was evaluated in a PD 45-year-old male patient. The patient’s right and left sides were randomly selected to use one of the prophylaxis dental protocols: REFIX dental gel/calcium (RDGCa) (experimental: 13, 14, 15 teeth) or Pumice Stone (PS) (control: 23, 24, 25 teeth). The products were applied using dental polishing brush during 10 seconds in each tooth surface. Schiff Air Index (SAI) for sensitive teeth (0–3) were performed by applying air jet to each tooth’s vestibular surface for 5 seconds after and before the prophylaxis. The patient reported pain and interruption of the stimulus before and after PS prophylaxis (SAI 3 and 3 respectively). There was a reduction in pain when RDGCa protocol was used (SAI 3—before/SAI 1—after). In this instance, the patient felt the stimulus but did not request to be interrupted. This contrasted with the outcomes of the initial stimulus as well as PS. Conclusion: The results showed that the RDGCa strategy was successful in lowering DH in PD patients.
