As compared to the potassium nitrate toothpaste, the use of potassium nitrate + aluminium lactate + hydroxylapatite toothpaste was effective in providing from DH relief not just instantly but as well as over a period of 2 weeks’, a study in Journal of Dentistry portrayed.

This randomised controlled trial comprised of people with a minimum of 2 sensitive teeth (Schiff  greater than equal to 2) to determine the efficacy of this combination toothpaste (test toothpaste)for DH pain relief as compared to control.

After routine brushing for 2 times using the test toothpaste or control toothpaste, the sensitivity of 2 test teeth was measured instantly after therapy and at 1 week and at 2 weeks. Thereafter, a whole mouth plaque score was determined.

Patients in the test group had significantly better pain reduction at specified time periods even though both toothpastes decreased DH in test teeth. Instantly after brushing, a relative risk decrease of Schiff sensitivity of 55% was observed which escalated to 81% after 1 week and 88.6 % after 2 weeks.

This combination toothpaste appears to be promising for pain alleviation from DH, as concluded. But, the study authors highlighted the need of future research of Potassium nitrate + aluminium lactate + hydroxylapatite toothpaste for prevention of DH pain.
