| Outline of Final Research Achievements |
Transmitted-light plethysmography (TLP) is a non-invasive objective method that uses a 525-nm LED to detect blood volume change in the pulp. Previous study showed that TLP amplitude is influenced by multiple factors, such as pathological conditions, tooth morphology, dental pulp circulating system, blood oxygen saturation, and so on. The present study aimed to investigate pulpal blood flow with TLP in healthy permanent maxillary incisors in different root formation stages and to assess the influences of body growth of children and tooth color on the TLP amplitude. The results indicated that the TLP amplitude and optical density may be affected by growth and development in children, thus indicating changes in the vascular dynamics of the pulp and hard tissue maturation during root formation stages.
