Summary
This study found key periodontopathogenic bacteria like Fusobacterium nucleatum and Porphyromonas gingivalis correlate with periodontitis severity. Microbial analysis aids in classifying periodontitis stages and grades.
Area of Science:
- Periodontology
- Microbiology
- Oral Health
Background:
- Periodontitis is a complex oral disease with varying severity and progression.
- Identifying specific bacterial species associated with different stages of periodontitis is crucial for effective management.
Purpose of the Study:
- To identify key periodontopathogenic species in correlation with the current periodontitis classification system.
- To evaluate the association between the frequency of specific bacteria and periodontitis stages and grades.
Main Methods:
- In-vivo study of 100 patients categorized into 4 periodontitis stages (I-IV) and a healthy control group (n=20 each).
- Samples from deepest periodontal pockets analyzed for Fusobacterium nucleatum, Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Tannerella forsythia, Treponema denticola, and Enterococcus faecalis.
Main Results:
- Fusobacterium nucleatum was the most prevalent (98%), followed by Tannerella forsythia (73%), Treponema denticola (66%), and Porphyromonas gingivalis (45%).
- Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis showed significant association with advanced periodontitis stages (IV) and higher grades (C).
- Specific bacteria like Tannerella forsythia and Treponema denticola were significantly more frequent in early stages.
Conclusions:
- Significant correlations exist between periodontopathogenic species, disease severity, and progression risk.
- Microbial analysis offers valuable supplementary information for periodontitis classification, particularly for advanced stages and grades.

02:54Evolutionary Relationships through Genome Comparisons
5.7K
Genome comparison is one of the excellent ways to interpret the evolutionary relationships between organisms. The basic principle of genome comparison is that if two species share a common feature, it is likely encoded by the DNA sequence conserved between both species. The advent of genome sequencing technologies in the late 20th century enabled scientists to understand the concept of conservation of domains between species and helped them to deduce evolutionary relationships across diverse...

02:40The Tree of Life - Bacteria, Archaea, Eukaryotes
32.2K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

01:23Phylogeny
43.7K
Phylogeny is concerned with the evolutionary diversification of organisms or groups of organisms. A group of organisms with a name is called a taxon (singular). Taxa (plural) can span different levels of the evolutionary hierarchy. For instance, the group containing all birds is a taxon (comprising the class Aves), and the group of all species of daisies (the genus Bellis) is a taxon. Phylogenies can likewise include just one genus (i.e., depict species relationships) or span an entire kingdom.

02:05Gene Evolution - Fast or Slow?
7.1K
The genomes of eukaryotes are punctuated by long stretches of sequence which do not code for proteins or RNAs. Although some of these regions do contain crucial regulatory sequences, the vast majority of this DNA serves no known function. Typically, these regions of the genome are the ones in which the fastest change, in evolutionary terms, is observed, because there is typically little to no selection pressure acting on these regions to preserve their sequences.

The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin...
