Published in Quintessence Int, Vol. 45 (8), pp. 703-11
Methodology
Double-blind randomized trial in 105 people with dentin hypersensitivity: 15% nano-hydroxyapatite fluoride-free toothpaste versus fluoride toothpaste versus placebo (35 per group), brushing for 2 minutes twice daily for 4 weeks; air blast, tactile and visual analogue scale scores at 2 and 4 weeks.
Key Findings
Cold-air and tactile sensitivity and visual analogue scale scores were significantly lower (P < .001) with nano-hydroxyapatite than with the fluoride or placebo groups at 2 and 4 weeks.
Conclusions
Fluoride-free nano-hydroxyapatite toothpaste gave quick relief within 2 to 4 weeks.
Limitations
Four-week follow-up; single research group; the abstract does not report funding.
Supplements Studied
encourage the application of nano-hydroxyapatite in fluoride-free toothpaste as an effective desensitizing agent
