Abstract:
Selective culture of human carious dentine for Veillonella strains resulted in the isolation of two strains of a Gram-negative, coccus-shaped bacterium that has not been described previously. Comparative 16S rRNA and dnaK gene sequence analysis indicated that the two strains were homogeneous and comprised a distinct lineage within the genus Veillonella, phylogenetically most closely related to Veillonella rodentium. This was supported by DNA-DNA hybridization, which showed clearly that the two strains were similar and distinct from other Veillonella species, and the production of major cellular fatty acids (C(13 : 0) and C(17 : 1)omega8), which is consistent with other members of the genus Veillonella. Based on these observations, strains RBV81 and RBV106(T) represent a novel species, for which the name Veillonella denticariosi sp. nov. is proposed, with the type strain RBV106(T) (=CIP 109448(T) =CCUG 54362(T) =DSM 19009(T)).

The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or grinding food.

Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...
