Photoacoustic Digital Tooth and Image Reconstruction of Tooth Root
2023 IEEE International Ultrasonics Symposium (IUS), 2023 Imaging of teeth is very important to doctors in the diagnosis and treatment of dental diseases. The main imaging modality currently used is Cone-Beam Computed Tomography (CBCT), which however suffers from ionizing radiation causing potential damage to human body.

Application of cryopreservation to tooth germ transplantation for root development and tooth eruption [PDF]
Scientific Reports, 2021 AbstractWe cryopreserved mouse tooth germs with widely open cervical margins of the enamel organ to overcome difficulties in cryoprotectant permeation and tested their efficacy by transplanting them into recipient mice. The upper right first molar germs of 8-day-old donor mice were extracted and categorized into the following four groups according to ...

Malformations of the tooth root in humans [PDF]
Frontiers in Physiology, 2015 The most common root malformations in humans arise from either developmental disorders of the root alone or disorders of radicular development as part of a general tooth dysplasia. The aim of this review is to relate the characteristics of these root malformations to potentially disrupted processes involved in radicular morphogenesis.

Tooth Eruption without Roots [PDF]
Journal of Dental Research, 2013 Root development and tooth eruption are very important topics in dentistry. However, they remain among the less-studied and -understood subjects. Root development accompanies rapid tooth eruption, but roots are required for the movement of teeth into the oral cavity.
