该体外研究的目的是使用pH成像显微镜（SCHEM-100，HORIBA Ltd.，日本京都）。提取的人乳牙，无论是轻度或严重的牙本质龋病变的颊舌切割切片，放置在pH成像传感器的显微镜。通过Levene方差齐性检验和Tukey HSD多重比较检验对pH值进行统计学比较（p < 0.05）。对于轻度和重度病变的原始牙本质，龋损中的最低pH值均低于完整牙本质的最低pH值（6.6，范围6.3-6.9）。轻度病变组最低pH值（6.2，范围5.8-6.4）与重度病变组最低pH值（6.0，范围5.9-6.2）比较差异有统计学意义（p < 0.05）。结果表明，SCHEM-100能够区分乳牙完整牙本质和龋坏牙本质的pH值分布。
The aim of this in vitro study was to evaluate the pH value of intact and carious dentin in primary teeth using a pH-imaging microscope (SCHEM-100, HORIBA Ltd., Kyoto, Japan). Bucco-lingual cut sections of extracted human primary teeth, which had either mild or severe dentinal caries lesions, were placed on the pH-imaging sensor of the microscope. The pH values were compared statistically by Levene's test for equality of variances and Tukey HSD multiple comparison test (p < 0.05). For both mild and severe lesions in primary dentin, the lowest pH values in the carious lesions were lower than those of intact dentin (6.6, range 6.3-6.9). There were statistical differences between the lowest pH value within the mild lesions (6.2, range 5.8-6.4) and that of the severe lesions (6.0, range 5.9-6.2) (p < 0.05). It was concluded that SCHEM-100 was able to distinguish the pH-value distribution of intact and carious dentin in primary teeth.
