Regular use of
combination toothpastes can offer dentine hypersenstivity (DH) pain relief.
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.
