Summary

This randomized, double-blind clinical study compared the efficacy of four toothpastes for the treatment of dentinal hypersensitivity:

• 5% potassium nitrate
• 5% fluoro-calcium-phosphosilicate
• 10% strontium chloride
• herbal toothpaste

Objective

The aim was to investigate which of the four toothpastes most effectively reduces sensitive teeth.

Method

• 160 patients with dentinal hypersensitivity
• Divided into 4 groups of 40 people each
• Sensitivity was tested with three types of stimuli:
  • tactile stimuli
  • air stimulus
  • cold water stimulus
• Evaluation using a visual analogue scale (VAS)
• Follow-up appointments after:
  • 2 weeks
  • 1 month
  • 2 months

Results

• All four toothpastes improved symptoms over the course of the study.
• However, the toothpaste with fluoro-calcium-phosphosilicate showed the best results.
• It was superior to the other groups in all test stimuli and time points overall.
• Potassium nitrate and strontium chloride also worked, but less effectively.
• The herbal toothpaste showed the least improvement.

Why fluoro-calcium-phosphosilicate performed better

According to the authors, this technology works in several steps:

• Particles bind to the tooth surface
• Calcium, phosphate, and fluoride are released
• Fluorapatite is formed in and on the dentinal tubules
• The tubules are sealed more deeply and stably
• Additionally, the enamel is remineralized

Limitations

• There was no placebo control group
• This could lead to a certain bias
• Further larger clinical studies are needed

Conclusion

The study concludes that a toothpaste with fluoro-calcium-phosphosilicate was more effective for sensitive teeth than toothpastes with potassium nitrate, strontium chloride, or herbal ingredients.
