简要总结
The study is designed as a prospective, randomized, parallel arm, double blinded, pilot clinical trial.The primary objective is to evaluate the efficacy of Sensi-IP +NaF as compared to a NaF toothpaste in the reduction of dentin hypersensitivity in adult participants over 14 days. Study endpoints include Evaporative Air blast Stimuli (Schiff Airblast Sensitivity Score), Tactile Stimuli (Yeaple probe Assessment), Visual Analogue Scale Evaporative Stimuli and the occurrence of adverse events. The study will include 2 study arms: 1. Sodium fluoride toothpaste with Sensi IP (N=23) and 2. Sodium fluoride toothpaste (N=23). Total of 46 participants (ages 18-80 years) with at least one hypersensitive tooth in 2 different quadrants which are anterior to the molars will be enrolled.
详细描述
The Study design is a prospective, randomized, parallel arm, double blinded, single study site, proof of concept clinical trial. The study will include 2 study arms: 1) Brushing with sodium fluoride toothpaste with Sensi IP (N=23) and 2) Brushing with sodium fluoride toothpaste (N=23).
A total of 46 adults (18 - 80 years of age) will be included in this clinical trial. To account for the potential of a 15% drop out, as many as 46 participants may be enrolled and treated with the goal of 20 participants per arm.
Study procedures will take place at the following timelines shown below:
Visit 1: Screening Visit -Informed consent; Screening for eligibility
Visit 2: Baseline Day 1: 7 days post screening; (+/- 1 Day) -Confirm eligibility, 1st treatment with allocated product

- •Crowns, veneers, or bridges
结局指标
主要结局
Change from baseline at Day 14 using the Schiff Airblast Sensitivity Score
时间窗: 14 Days
Schiff Airblast sensitivity score is mainly used to assess participant response to evaporated air stimuli. The scale is 0-3 and higher scores mean a worse outcome.
次要结局
- Change from baseline at Day 14 using the Yeaple probe assessment(14 Days)
- Change from baseline at Day 14 using the Visual Analogue Score (VAS) for pain following evaporative stimuli(14 Days)
