研究概览
简要总结
The purpose of the study is to evaluate the efficacy of Sensi-StopTM strips (Procter & Gamble™) on the relief of dentinal hypersensitivity. In other words, do Sensi-StopTM strips (Procter & Gamble™) reduce or eliminate cold sensitivity in teeth? In addition, the investigators will evaluate whether there is a difference in the Sensi-StopTM strip (Procter & Gamble™) effectiveness when the product is placed by a dental professional compared to self-placement by the person with sensitive teeth. This product is not experimental.
详细描述
There are two groups in this research study: 1) The Self Applied group, and 2) the Professionally Applied group.
Once it is determined that interested individuals qualify to participate in the study and have determined that they want to participate, the group that participants are in will be determined. The study has been designed to ensure that 66% of the study participants receives strips that contain the active ingredient and 33% of the subjects receive strips without the active ingredient. This means that there is a 1 out of 3 chance that participants will be assigned to receive the strip(s) without the active desensitizing ingredient. At the end of your 8-week participation, if it turns out that participants received the strips without the active ingredient, they will be offered a sample pack with two strips that contain the active desensitizing ingredient for them to use at home.

入选标准
- •Patient presents in good general health with no allergies to commercial dental products and are currently not using any desensitizing agents.
- •If participants are using desensitizing agent the participant must agree to not use any desensitizing agents in the 4 weeks leading up to the baseline data collection appointment and during the following 8 week length of the study.
- •Patients with a history of having used Sensi-Stop Strips (Procter & Gamble™) in the past will not be eligible to participate because it will not be possible to maintain blindness to the treatment that they receive.
- •Patients will also have at least the following baseline measurements:
- •i. Schiff Air Scale = equal to or greater than 1
- •ii. Verbal Rating Scale = equal to or greater than 1
- •iii. Recession= 1mm or greater
排除标准
- •Any dental pathology resulting in pain that could confound the study findings would render the patient ineligible: e.g. advanced dental decay, pulpitis, fractured teeth, fractured restorations, chipped teeth, cracked teeth, severe gingival inflammation, post-restorative sensitivity, marginal leakage, severe periodontal disease, as characterized by purulent exudate, generalized mobility, and/or severe recession.
- •Also, if potential study subjects are not willing to agree to avoid the use of desensitizing and/or whitening products they will not be enrolled.
- •Adults lacking in the ability to give consent will also be excluded.
研究组 & 干预措施
Prof applied oxalate
Subjects will be randomized to either receive the Prof applied oxalate Crest Sensi-Stop strip (Procter & Gamble™). The oxalate strip contains 3% dipotassium oxalate desensitizing gel. The placebo strip is blank. The strips will be placed by a licensed dental professional and will be in place for 10 minutes. Subjects will be instructed to not rinse their mouth, drink, eat or brush their teeth for 30 minutes after completion of the treatment.
干预措施: Prof applied oxalate (Device)
Self-applied oxalate
Participants randomized to the Active Comparator Group will have the following intervention: Intervention: self-applied oxalate (Crest Sensi-Stop strip Procter & Gamble™), which contains 3% dipotassium oxalate desensitizing gel. The strip will be placed by the participant, following the manufacturer's directions. The strip will be left in place for 10 minutes. Subjects will be instructed to not rinse their mouth, drink, eat or brush their teeth for 30 minutes after completion of the treatment.
干预措施: Self applied oxalate (Device)
Prof applied placebo
Subjects will be randomized to either receive the Prof applied placebo Crest Sensi-Stop strip (Procter & Gamble™). The oxalate strip contains 3% dipotassium oxalate desensitizing gel. The placebo strip is blank (sham). The strips will be placed by a licensed dental professional and will be in place for 10 minutes. Subjects will be instructed to not rinse their mouth, drink, eat or brush their teeth for 30 minutes after completion of the treatment.

结局指标
主要结局
Schiff Air Test: Mean Reduction in Sensitivity Between Groups
时间窗: 30 Minutes Post, 4 Weeks Post, 8 Weeks Post Baseline
An analysis of covariance model was used to compare mean reduction in sensitivity scores (SAS and VRS) between groups at each post-treatment time point. A linear mixed effect model with group, time and baseline score as fixed effects and a random subject effect was used to compare the sensitivity outcomes between groups across time. The effect of location was also examined using this model. Schiff Air Scale 0-3 Measurement of Dentinal Hypersensitivity 0 Tooth/Patient did not respond to the air stimulus 1. Tooth/Patient responded to the air stimulus but did not request discontinuation of the stimulus 2. Tooth/Patient responded to the air stimulus and request discontinuation or moved from the stimulus 3. Tooth/Patient responded to the air stimulus, considered the stimulus painful, and requested discontinuation of the stimulus
