Home treatment protocol for dentin hypersensitivity with hydroxyapatite-based biodynamic toothpaste and lactoferrin: a pilot study.

BACKGROUND

In recent years, there has been a gradual increase in cases of dentin hypersensitivity, often related to gingival recession, enamel abrasion from brushing, and wear of root cementum. This condition can affect patients of all ages but is more common between 20 and 40 years of age, especially in females and individuals with periodontal disease. The study aimed to evaluate and compare the efficacy over time of a product for at-home treatment of dentin hypersensitivity.

METHODS

One hundred five patients aged between 28 and 65 years were recruited, each with at least two hypersensitive teeth due to erosions, abrasions, gingival recessions, and/or periodontal diseases. Participants were selected through the Schiff Test and anamnestic evaluations, with compilation of periodontal records. Patients are instructed to use the product three times a day, to be applied with a soft-bristled toothbrush and/or topically as a gel on teeth with strong sensitivity and deep cervical lesions and gingival recessions.

RESULTS

There were no statistically significant differences between measurements at baseline and after scaling. However, significant differences were observed in follow-ups from the 1st to the 8th week, with a progressive decrease in values. The average trend of product efficacy increases over time according to the Schiff Test, with a significant improvement observed at follow-ups conducted after four and eight weeks.

CONCLUSIONS

The results indicate that the product enriched with biomimetic hydroxyapatite and lactoferrin is effective in reducing the painful symptoms of dentin hypersensitivity and in counteracting the inflammatory state of the supporting tissues.
