Inclusion criteria
Inclusion criteria: Those who meet all of the following criteria are eligible (1) Have at least one tooth that is judged to have a score of 1 or 2 on the criteria in Section 6 for abrasion and cold air stimulation. (2) Those who are 20 years of age or older at the time of consent (regardless of gender).

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Evaluation of abrasion pain, cold air pain, and subjective evaluation using the criteria shown in the table below. (1) Abrasion pain: The tooth surface is rubbed perpendicularly at a constant pressure (40g) using a probe capable of applying a constant pressure to the cervical area. The adjacent tooth is covered with gauze to isolate it from the test tooth, and pressurized air (0.38 MPa) is blown on the labial cervical region of the test tooth for 1 second. The physician in charge performs calibration using the measuring instruments. (3) Subjective evaluation: The physician in charge will evaluate the subject's own hypersensitivity state in daily life by interviewing the subject. | — |
