About this study
Official title: Evaluation of the Efficacy of a Product for Oral Care in Use Test Under Dentist Control.
The goal of this study is to learn if a tooth gel works to alleviate teeth hypersensitivity in adults. It will also learn about the safety of the product.
The main question it aims to answer is:
- Does the tooth gel help to improve signs of teeth hypersensitivity?
Researchers will compare before and after product use to see if it works to improve teeth sensitivity. Participants will:
- Use assigned products daily for 14 days
- Visit the clinic on the established days during 14 days for check-ups and evaluation
- Conditions
- Dentine Sensitivity
- Being tested
- Desensitizing tooth gel
- Medical subject headings
- Dentin Sensitivity
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Desensitizing tooth gelOther
Desensitizing tooth gel was used 3 times a day after meals during 14 days
| Study group | Role | What they receive |
|---|---|---|
| Desensitizing tooth gel | Experimental | Not described Receives: Other: Desensitizing tooth gel |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Baseline in teeth sensitivity to cold air at 14 days.
Change evaluated by VAS score scale from 0 to 3, where 0 means the absence of pain while 3 is the highest pain.
Measured: From enrolment to the end of use at 14 days.
Change from Baseline in teeth sensitivity to periodontal probe at 14 days
Change evaluated by VAS score scale: from 0 to 10, where 0 means the absence of pain while 10 is the highest pain
Measured: From enrolment to the end of use at 14 days.
