Abstract
Objective: This study is to compare a new hyperesthesia reliever patch with other conventional ones in the market and thus to provide a preliminary support for potential commercialization of a convenient product. Methods: The sample includes 47 adults individuals who reported hypersensitivity teeth. We selected the most painful hypersensitivity teeth based upon self-reporting from the participants, checked their conditions in the eyes, and then implemented cold test and electric pulp tests. We conducted and recorded the test results four times−pre-patching, a day, three days, and six days after patching. On the sixth day, this study surveyed participant satisfaction.Results: We observed no statistically significant difference between groups in VRS score in the cold test. However, average score for the Experiment 2 declined similarly as that for the Positive Control Group did. In contrast to the prepatching period, the average score declined after the first day for the Experiment 2 and the Positive Control Group (p<0.05); it fell down after three days for the Experiment 1 (p<0.01).Conclusion: It is estimated that there are pain relieving effects in the Experiment 2 as in the Positive Control Group. In the future, we need to recruit more participants, expand the test duration, and run studies with placebos. Moreover, we need to investigate whether there are any differences between toothpastes, mouthwashes, and new patches under research for intraoral application with greater duration for earlier effectiveness.
