Researchers have recently found that aluminum lactate/potassium nitrate/hydroxylapatite toothpaste is efficacious when compared to potassium nitrate control toothpaste for the prevention of dentine hypersensitivity both immediately and over a 2 week period.

The study objective was to determine the efficacy of a cosmetic aluminum lactate/potassium nitrate/hydroxylapatite toothpaste for the reduction of dentine hypersensitivity (DH) pain as compared to a control toothpaste.

The study was a randomized, examiner-blind, two treatment arm, parallel controlled trial in healthy adults with at least 2 sensitive teeth. At baseline, immediately after treatment and at 7 and 14 days of twice-daily brushing of the test or control toothpaste the sensitivity of 2 test teeth was measured following iced-water (Schiff and VAS) and tactile (Yeaple probe) stimuli, and a whole mouth plaque score was obtained. Participants also completed a whole-mouth VAS and DHEQ15 quality of life questionnaire at baseline, 7, and 14 days.

The result was;
--Both kinds of toothpaste reduced DH in test teeth, but pain reduction in the test group was significantly better at all time points and by all measures.

--There was a relative risk reduction of Schiff sensitivity of 55 % immediately after brushing which rose to 81 % after 7 and 88.6 % after 14 days.

--There were no differences in plaque, whole mouth VAS, or DHEQ15 scores at any time point.

In conclusion, this study demonstrated the efficacy of an aluminum lactate/potassium nitrate/hydroxylapatite toothpaste compared to a potassium nitrate control toothpaste for the prevention of dentine hypersensitivity both immediately and over a 2 week period.
