Dental Follicle Cells: Roles in Development and Beyond

Stem Cells International, 2019
Dental follicle cells (DFCs) are a group of mesenchymal progenitor cells surrounding the tooth germ, responsible for cementum, periodontal ligament, and alveolar bone formation in tooth development.

Bilateral fusion in primary mandibular teeth: A report of two cases

Journal of Indian Society of Pedodontics and Preventive Dentistry, 2011
The rare anomaly of fusion in primary dentition has very little documentation in Indian population. Two rare cases of bilateral fusion between primary mandibular lateral incisors and canines and primary mandibular central incisors and lateral incisors ...

Boundary feature fusion network for tooth image segmentation [PDF]

arXiv
Tooth segmentation is a critical technology in the field of medical image segmentation, with applications ranging from orthodontic treatment to human body identification and dental pathology assessment. Despite the development of numerous tooth image segmentation models by researchers, a common shortcoming is the failure to account for the challenges ...

Local topological algebraicity of analytic function germs [PDF]

arXiv, 2014
T. Mostowski showed that every (real or complex) germ of an analytic set is homeomorphic to the germ of an algebraic set. In this paper we show that every (real or complex) analytic function germ, defined on a possibly singular analytic space, is topologically equivalent to a polynomial function germ defined on an affine algebraic variety.
