The current pulp diagnostic techniques based on subjective patient response to electrical or thermal stimuli are unable to assess tooth vascularization, which is a true indicator of pulp vitality. The present study evaluates thermography as a pulp vitality test, assessing tooth recovery following thermal stimulation.
A model simulating intrapulpal circulation was developed. Superficial thermographic measurements were obtained from teeth with and without elevation of the intracoronal temperature before and after applying thermal stress with cold. The data were analyzed using analysis of variance (ANOVA), and the level of significance was set at P<0.05.
The model obtained could help differentiate between teeth with and without simulated pulp circulation. Recovery following application of thermal stress showed significant differences between the two types of teeth.
Thermography has the potential to be used as a diagnostic tool for the vascularity status of the dental pulp.
当前基于患者对电刺激或热刺激的主观反应的牙髓诊断技术无法评估牙齿血管化情况，而牙齿血管化是牙髓活力的真实指标。本研究评估热成像作为一种牙髓活力测试方法，评估热刺激后牙齿的恢复情况。
建立了一个模拟牙髓内循环的模型。在施加冷热应力前后，从冠内温度未升高和升高的牙齿获取表面热成像测量数据。使用方差分析（ANOVA）对数据进行分析，显著性水平设定为P<0.05。
所获得的模型有助于区分有和没有模拟牙髓循环的牙齿。两种类型的牙齿在施加热应力后的恢复情况存在显著差异。
热成像有潜力用作诊断牙髓血管状态的工具。
