Abstract:
Four Gram-stain-positive, catalase-negative, coccoid-shaped isolates were obtained from the oral cavities of wild boars and characterized by phenotypic and phylogenetic studies. On the results of biochemical tests, the organisms were tentatively identified as a streptococcal species. Comparative 16S rRNA gene sequencing studies confirmed that the organisms are members of the genus Streptococcus, with Streptococcus equi subsp. equi ATCC 33398(T) as their closest phylogenetic relative (94.7 % similarity). DNA-DNA hybridization analysis showed that the isolates displayed less than 10 % relatedness to Streptococcus equi subsp. equi DSM 20561(T). From the phylogenetic and phenotypic evidence, the four isolates represent a novel species of the genus Streptococcus, for which the name Streptococcus dentapri sp. nov. (type strain NUM 1529(T) =JCM 15752(T) =DSM 21999(T)) is proposed.

Tooth Anatomy
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.
Oral Cavity
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...
