NCT01063530

Brief Summary

The purpose of the study is to confirm the clinical effectiveness and safety of topical diammine silver fluoride (DASF) as a tooth desensitizer in adulst by comparing it to the application of sterile water. The study will be conducted in two different sites in Peru. Participantes will be 144 adults who will have at least one vital maxillary or mandibular cuspid or premolar with a cervical defect on the buccal surface and clinical hypersensitivity in response to air. Subjects will be randomly assigned to a topical application of DAS or sterile water. The reduction of pain (sensitivity) using a 100 mm VAS, will be determined. Safety will be also determined by evaluating the gingival condition (erythema, white changes, ulceration, staining) before and ater the application of the products. The evaluation times will be 24 hours and 7 days.

Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • To be included the subject must have at least one vital maxillary or mandibular cuspid or premolar with a cervical defect on the buccal surface and clinical hypersensitivity in response to air with a score not less than 15 on the VAS for pain (described below).
  • The individual will have generally healthy gum tissue surrounding this tooth and no ulceration, and no leukoplakia (white changes) in this gingival tissue.

You may not qualify if:

  • Excluded will be subjects who are using any type of commercially available tooth desensitizer, have received a fluoride varnish treatment within the last month, or who are taking prescription medications of any kind, are taking aspirin or nonsteroidal anti-inflammatory drugs habitually, and women who are pregnant.
  • Individuals using smokeless tobacco will be excluded. Individuals with known sensitivity to silver or other heavy-metal ions will be excluded.
