Abstract

Aim: This clinical study aimed to evaluate the efficacy of a toothpaste containing a proprietary REFIX technology (Regenerador + Sensitive DentalClean, Rabbit Corp) against dentin hypersensitivity. Materials and methods: Fifty-three volunteers who fulfilled the inclusion criteria and signed the consent form were included. They were examined for dentin hypersensitivity. The participants received a 1-second blast of air, and the tooth sensitivity, from 0 to 10, was immediately evaluated using a visual analog scale (VAS). Then, the participants brushed their teeth with the multifunctional toothpaste, and dentin hypersensitivity was tested a second time using the same scale. The participants continued to use the toothpaste three times a day for 1 week, after which dentin hypersensitivity was recorded for the third time. Data were statistically analyzed using analysis of variance (ANOVA) and Tukey\'s test (α = 0.05). Results: The mean patient age was 40 years, and 70% of the 53 subjects were female. There was a significant reduction in dentin hypersensitivity immediately after using the toothpaste and after 1 week. The baseline mean patient-reported pain score was severe (6.5 ± 2.4). Immediately after the first use of the toothpaste, the mean reported pain significantly decreased to mild pain (2.5 ± 2.5) (p < 0.05). After 1 week of consistent use of the toothpaste, the pain score reduced significantly (0.7 ± 1.2) (p < 0.05), and most participants reported no pain, demonstrating the effectiveness of the REFIX technology against dentin hypersensitivity. Conclusion: This clinical trial shows that the use of the phosphate-based desensitizing toothpaste containing REFIX technology significantly reduces dentin hypersensitivity after 1 week of consistent use. Clinical significance: The absence of pain, a desired clinical condition in patients with dentin hypersensitivity, was reached with the use of desensitizing toothpaste containing REFIX technology after 1 week of use. Such condition positively impacts quality of life, providing a healthier daily routine for patients.
