A scaler tip or the like that is detachably attached to the tip of a dental ultrasonic scaler or a handpiece of a dental air scaler is gradually worn away from the tip during use.
Thus, conventionally, a wear checker 51 for the scaler tip shown in FIG. 8 has been used to check the wear amount of the scaler tip.

The wear checker 51 for the scaler chip shown in FIG. 8 is a business card size and has a card shape, and on its surface 51a, there are five types of scaler chips 52 to 56 and scaler chips 52 to 56, respectively. Three lines 57 to 59 that serve as a measure of the amount of wear are drawn.
The lower end portion of the wearer 51 for the scaler tip is provided with five notches 60 for receiving a two-sided width portion provided on the scaler tip (not shown).
Then, the wear amount of the scaler tip is determined by inserting the two-face width portion of the scaler tip whose wear amount is to be checked into the notch 60 of the corresponding scaler tip 52 to 56, so that the outer shape of the scaler tip is as follows. The scaler tip wear checker 51 was placed on the surface 51a of the scaler tip so as to match the outer shape of the corresponding scaler tip 52 to 56, and the wear amount of the scaler tip was checked.
Note that the line 59 has a larger amount of wear than the line 58, and the line 58 has a larger amount of wear than the line 57. That is, the line 57 shows the smallest amount of wear, and the line 59 shows the largest amount of wear.

However, the notch 60 of the scaler tip wear checker 51 shown in FIG. 8 is formed larger than the two-sided width portion of the scaler tip, and the scaler tip two-sided width of the scaler tip whose wear amount is to be checked. When the portion is inserted into the cutout 60 of the corresponding scaler chip 52 to 56, the portion having the two surface widths in the cutout 60 is rattled.
In addition, on the surface 51a of the scaler tip wear checker 51, the outer shape of the scaler tip whose wear amount is to be checked and the corresponding outer shape of the scaler tips 52 to 56 are determined. There was annoyance that had to be adjusted accurately.
Further, a scaler tip whose wear amount is to be checked is arranged on the surface 51a of the scaler tip wear checker 51 with the outer shape of the scaler tip whose wear amount is to be checked and the corresponding outer shape of the scaler tips 52 to 56. At the time of matching, depending on the line of sight and skill of the confirmer (operator), there is a possibility that the outer shape of the scaler chip whose wear amount is to be checked and the outer shape of the corresponding scaler chips 52 to 56 are not exactly matched.
