Plaque
• Consists of microorganisms and extracellular matrix
-Microorganisms: streptococcus mutans and anaerobes (bacterias)
-Extracellular matrix: proteins, lipids and polysaccharids
Dental Calculus• Mineralized plaque that attaches to the tooth surface
-Supra-gingival: attaches to cervical crown
-Sub-gingival: attaches to root surface• Shows up mostly on lingual surfaces of anterior teeth and buccal
surfaces of molars• Amount of dental calculus is scored on a 3 point scale (1 being
slight, 3 being considerable)
Dental CariesRange in size and shape
Demineralization of enamel by the waste products of oral bacteria.
S. mutans, S. aureus
And so does everything!
Factors
• The two main factors influencing both caries and calculus are oral hygiene and diet
Dietary Factors
Complex carbohydrates survive longer in oral cavity, consumed over longer duration
Carbohydrates more easily digested by oral bacteria, create acidic waste easier
Sucrose, starch
Saliva neutralizes oral pH and breaks down food particles
Refined V. Unrefined Food Texture
Refinement and processing influence clearance time from oral cavityFood boiling and processing breaks down cell walls and releases carbohydrates
Oral hygiene
• Fluoride Exposure
Periodontal disease
• Plaque, hygiene and diet influence periodontal disease• Bacteria from plaque, dental calculus and from the mouth in general
start to make their way to the periodontal ligaments and aveolar region• As a response against the bacteria an immune response is started• This response causes irritation and inflammation• As the inflammation increases the collagen fibers become disrupted and
the legion begins to grow• With an expanding legion and more inflammation a loss of ligament
attachments occur• This can result in tooth loss and bone loss
