本研究旨在分析荧光辅助排龋术（FACE）和剩余牙本质厚度对髓室温度变化的影响。 本研究采用新鲜拔除的乳磨牙和牙髓微循环模型。根据基于既往研究的把握度分析（把握度为90%）计算样本量。因此，需要40个样本。设计标准洞（3 × 3 mm）以获得2 mm的髓室距离，并在每颗牙齿（n=10）中，修改这些洞以获得1.5 mm、1 mm和0.5 mm的髓室最终距离。将牙齿的冠状部分放置在丙烯酸板上，该丙烯酸板具有用于进给和提取针以及热电偶的三个间隙。记录从开始时间到15 s和30 s，1 min，1.5 min，2 min，2.5 min，3 min间隔的温度变化。 结果表明，随着FACE作用时间的延长，腔底与髓室之间的厚度减小，温度变化增加。然而，所记录的值并不意味着对髓室造成不可逆的损伤。 最近的研究表明，Face是一种合适的龋齿检测系统，不影响髓室的健康，可以安全地用于乳牙。 关键词：龋病评估，龋齿，牙髓，儿童牙科。
This study aimed to analyze the effect of the Fluorescence Aided Caries Excavation (FACE) and the remaining dentin thickness on the temperature changes of the pulp chamber. Freshly extracted deciduous molars and a pulpal microcirculation model were used in the study. The sample size was calculated according to power analyses (power at 90%) based on previous studies. Thus, 40 samples were needed. Standard cavities (3x3 mm) were designed to obtain a 2 mm distance through to the pulp chamber, and in each tooth (n=10), these cavities were modified to obtain 1.5 mm, 1mm, and 0.5 mm final distance through to the pulp. Coronal parts of the teeth were placed on an acrylic plate with three gaps for feeding and extraction needles and the thermocouple. The temperature changes were recorded from the initial time to 15 s and 30 s,1 min, 1.5 min, 2 min, 2.5 min, 3 min intervals. The results showed that hence the thickness between cavity floor and pulp chamber was decreased, and application time of FACE was increased, an increase in temperature changes was detected. However, the recorded values were not mean to cause irreversible damages to the pulp chamber. The recent study showed that Face is an appropriate caries detecting system that does not affect the pulp chamber’s health, and it can be safely used in the primary teeth.
