Description of normal microflora and lifespan. Explanations of oral bacteria and side effects of left untreated.
Viral versus Fungal
Types of bacteria involved in gastrointestinal diseases with onset time and side effects
Develop along with intestinal epithelium over 1-2 years post-birth.
Commensal & mutualistic.
- Intestine and mucosal layer develop with microflora
- Mutual is tic: Organisms that make vitamins, metabolize viral acids
1000 species.
- What you eat, autism, etc.. lead to abnormal microflora
the bacteria come from about 30 or 40 species (normal)
- bacteriorities flagellus (seen in everyone)
- Enterobacter species

Diseases of the Oral Cavity
Bacterial
Plaque: NOT A DISEASE
- Can contain up to 30 different species of bacteria
- Held together by polysaccharides by bacteria that do sugar metabolism
- Don;t want precipitated minerals: BECOMES TARTAR
Ecological succession
- 300-500 cells thick, if left on teeth it can calcify into tartar
- Tartar can lead to anaerobic pockets: Irritate gums
- Tooth enamel will start to demineralization from the acids coming from tartar
Caries: IS DISEASE AKA Cavities
Lain for cariosis: Rotten
- Teeth dissolving
- Fluoride helps, but only up until age 20
Periodontal: After plaque, tartar, and caries: IS A CHRONIC DISEASE
- Gum inflammation and erosion
- Erosion of periodontal ligaments (they hold teeth in place)
- No pain
- Teeth will fall out
- Gram-negative rods proliferate in mouth
- Systemic problems can occur as a result
- Diagnosed by observation and gum depth
