Biomimetic Hydroxyapatite Toothpaste and Mouthwash for Reducing Dental Sensitivity (SENS-BIOREP)

September 16, 2025 updated by: Andrea Scribante, University of Pavia

Effect of Biomimetic Hydroxyapatite-Based Toothpaste and Mouthwash on Dental Sensitivity in Patients With Gingival Recession: A Randomized Controlled Clinical Trial

This randomized controlled clinical trial evaluates the effectiveness of a biomimetic hydroxyapatite-based toothpaste and mouthwash in reducing dental sensitivity in patients with gingival recession. A total of 100 participants will be randomly assigned to two groups. The control group will receive Biorepair Total Protection toothpaste, and the trial group will receive Biorepair high-density mouthwash. Both products will be applied for 30 seconds. Dental sensitivity will be assessed before and after treatment using the Shiff Air Index and the Visual Analogue Scale (VAS).

Study Overview

Status

Status

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • Male and female subjects aged between 18 and 70;
  • Subjects with gingival recession and tooth sensitivity;
  • Subjects who have agreed to give their free written informed consent to participate in the study.

Exclusion Criteria:

  • Male and female subjects who are not adults;
  • Subjects without gingival recessions;

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Active Comparator: Control Group - Toothpaste
50 participants will receive a single 30-second application of Biorepair Total Protection toothpaste. The intervention aims to reduce dental sensitivity in patients with gingival recession. Clinical indices (Schiff Air Index and VAS) will be assessed before and after application.
Device: Biorepair Total Protection Toothpaste
Application of Biorepair Total Protection toothpaste for 30 seconds, performed once in a clinical setting. The aim is to reduce dental sensitivity in patients with gingival recession.
Experimental: Trial Group - Mouthwash
50 participants will receive a single 30-second application of Biorepair high-density mouthwash. The intervention aims to reduce dental sensitivity in patients with gingival recession. Clinical indices (Schiff Air Index and VAS) will be assessed before and after application.
Device: Biorepair High-Density Mouthwash
Application of Biorepair High-Density mouthwash for 30 seconds, performed once in a clinical setting. The aim is to reduce dental sensitivity in patients with gingival recession.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Change in Dental Sensitivity Measured by the Schiff Air Index
Time Frame: T0 (baseline) and T1 (immediately post-treatment, same visit)
Variation in dental sensitivity scores assessed using the Schiff Air Index at baseline (T0) and after a 30-second application of either toothpaste or mouthwash (T1). The Schiff scale ranges from 0 (no response) to 3 (painful response to air stimulus), with higher scores indicating greater sensitivity.
T0 (baseline) and T1 (immediately post-treatment, same visit)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Change in Pain Perception Measured by the Visual Analogue Scale (VAS)
Time Frame: T0 (baseline) and T1 (immediately post-treatment, same visit)
Variation in perceived pain intensity related to dental sensitivity, reported by the patient using the Visual Analogue Scale (VAS) at two timepoints: T0 (baseline) and T1 (immediately after 30-second treatment with either toothpaste or mouthwash). The VAS is a 10 cm horizontal line ranging from 0 (no pain) to 10 (worst imaginable pain).
T0 (baseline) and T1 (immediately post-treatment, same visit)

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure.
