牙科材料的荧光会影响激光荧光设备诊断的读数。盐酸四环素(TCH)呈荧光，滞留在牙齿中。本研究的目的是评估TCH对诊断性阅读的影响。制备了含有不同量TCH的滤纸盘(每盘0.16-10 mg)。1日龄新生大鼠皮下注射TCH 29d，摘除下颌骨。测定紫外线照射前后大鼠牙盘和第一磨牙的诊断值(D-V)。含有TCH的盘片的D-V随TCH量的增加而增大。TCH含量较低(0.16-1.25 mg)的光盘的D-V值约为10-15，在UV下这些值增加到30-40。此外，磨牙在紫外线照射后的D-V是照射前的两倍。这些结果表明，TCH可能会影响诊断仪器获得的读数。
Dental materials that fluoresce affect the reading of the laser fluorescence device DIAGNOdent. Tetracycline hydrochloride (TCH) shows fluorescence and is retained in teeth. The aim of this study was to evaluate the effects of TCH on the DIAGNOdent reading. Filter-paper discs that contained various amounts of TCH were prepared (0.16–10 mg per disc). One-day-old newborn rats were subcutaneously injected with TCH for 29 days, and their mandibles were then removed. The DIAGNOdent values (D-V) of the discs and first molars of the rats were measured before and after they were subjected to ultraviolet irradiation (UV). The D-V of discs containing TCH increased depending on the amount of TCH. The D-Vs of discs with lower amounts of TCH (0.16–1.25 mg) were approximately 10–15, and these values increased to 30–40 under UV. In addition, the D-Vs of molars after UV were twofold greater than those before UV. These results suggest that TCH might affect the readings obtained by DIAGNOdent.
