TITANIUMTETRAFLUORIDE FOR TREATMENT OF HYPERSENSITIVE DENTIN

Dentine hypersensitivity in cervical areas and severe dentine sensitiv ity in teeth prepared for restorations were treated with a titaniumtet rafluoride solution. Patients included in the study complained spontan eously about the sensitivity in intact dentine surfaces. Thirty patien ts with at least one tooth on each side of the maxilla and/or mandible experiencing moderate or severe sensitivity in cervical areas partici pated. The degree of sensitivity was determined by scraping an explore r over the dentine surface and by air blast. At least one sensitive to oth on one side of the jaw was treated with titaniumtetrafluoride, and one on the contralateral side with a placebo solution. Results were r ecorded after one month, four, eight and twelve months, using the expl orer and the air blast. A total of 102 teeth, of which 51 were control s, were treated. About 80% responded to the treatment with-the titaniu mtetrafluoride solution after one month and 55-84% thereafter. No resp onse occurred in any of the placebo-treated teeth. Twenty patients wit h severe sensitivity in dentine of teeth prepared for crowns were also treated with the titaniumtetrafluoride solution when trying casts and crowns and before cementation. A total of 52 teeth were treated. Dese nsitizing effects occurred in 75% of the patients, with 36 of the 52 p repared teeth.
