Prevalence of enamel pearls in teeth from a human teeth bank.
Enamel pearls are anatomical structures that can bring about clinical implications if associated with the retention of plaque, in turn resulting in periodontal disease. In an attempt to avoid periodontal disease, the removal and treatment of these enamel pearls, may be a necessity in some circumstances. A total of 45,785 extracted teeth from a human teeth bank were analyzed for the presence of ...
متن کاملEnamel prism orientation within human teeth
Dental enamel is the most highly mineralised and hardest biological tissue in human body [16]. It is made of hydroxylapatite (HAP) Ca5(PO4)3(OH), which is hexagonal (6/m). The lattice parameters are a = b = 9.418 Å and c = 6.875 Å. About the inner structure of dental enamel it’s known, that it is composed of elongated “enamel prisms” of about 20μm diameter [1]. The crystallographic structure, r...
متن کاملThe dentin-enamel junction and the fracture of human teeth.
The dentin-enamel junction (DEJ), which is the interfacial region between the dentin and outer enamel coating in teeth, is known for its unique biomechanical properties that provide a crack-arrest barrier for flaws formed in the brittle enamel1. In this work, we re-examine how cracks propagate in the proximity of the DEJ, and specifically quantify, using interfacial fracture mechanics, the frac...
متن کاملIncremental enamel development in modern human deciduous anterior teeth.
This study reconstructs incremental enamel development for a sample of modern human deciduous mandibular (n = 42) and maxillary (n = 42) anterior (incisors and canines) teeth. Results are compared between anterior teeth, and with previous research for deciduous molars (Mahoney: Am J Phys Anthropol 144 (2011) 204-214) to identify developmental differences along the tooth row. Two hypotheses are ...
