In several experiments it was examined, whether slight deviations from the using reglementation for the PERIOTEST-device alter the measurement results. Tilting of the handpiece against ground or variation of the distance between handpiece and the surface of the tooth within the suggested intervals did not alter the PERIOTEST-value. If the measurement was done more incisal then specified, the PERIOTEST-value increased, if the measurement was done more cervical, the value decreased. Tilting the handpiece against the tooth surface within +/- 8 degrees in horizontal and +/- 6 degrees in vertical direction gave only little effect on the PERIOTEST-value on clinical firm upper front teeth.
在多项实验中，研究了与PERIOTEST设备使用规范的轻微偏差是否会改变测量结果。牙钻机头相对于地面倾斜或在建议间隔内改变牙钻机头与牙齿表面之间的距离，均未改变PERIOTEST值。如果测量位置比规定的更靠近切端，则PERIOTEST值会增加；如果测量位置更靠近牙颈部，则该值会降低。在临床稳固的上前牙上，将牙钻机头在水平方向上相对于牙齿表面倾斜 +/- 8度，在垂直方向上倾斜 +/- 6度，对PERIOTEST值的影响很小。
