67
Q

Describe the difference between dental plaque biofilm and dental calculus

A

Dental plaque biofilm is the sticky film of bacterial colonies that constantly forms on the surface of teeth. Dental calculus is oral biofilm that has been mineralized by calcium and phosphate salts from saliva. When dental plaque biofilm is not removed form the teeth, it will hard and create dental calculus.

68
Q

List the sequence for dental plaque biofilm formation.

A

The first stage is the deposition of salivary components, know as the acquired pellicle. Although the acquired pellicle has a protective function, acting as a barrier to acids, it also serves as an initial site of attachment for bacteria

Bacteria such as gram-positive cocci, are the first microorganisms to adhere to and colonize on teeth. Early plaque consists primarily of aerobic, gram positive cocci such as steptococcus mutans.

Once bacteria have adhered to the tooth surface, they colonize & multiply. As the growth process continues, an intermicrobial matrix forms and connects the bacterial colonies. The biofilm is now a fully functioning community of different species.

69
Q

List 3 criteria required for dental caries to occur

A
  1. Susceptible tooth - any tooth that has erupted into the oral cavity, a tooth with optimum fluoride content is less susceptible to the process of dental caries
  2. Acidogenic microorganisms - bacteria that produces acids through the metabolism of fermentable carbohydrates, streptococcus mutans and lactobacillus are consistently associated with dental decay
  3. Cariogenic food source - a food source that is associated with the development of dental caries, sugars that are easily fermented and breakdown into simple sugars (glucose, fructose, maltose & lactose)
    Acidogenic bacteria will ferment these carbohydrates and produce acid, which will begin to demineralize the tooth
70
Q

Define demineralization

A

The process that occurs when acids produced in the oral cavity diffuse into the tooth and dissolve the calcium and phosphate minerals. If the acid attacks are infrequent and of short duration, saliva can assist in the repairing of damage by neutralizing the acid and replacing minerals lost from the tooth. If however, the flow of saliva is low, the bacterial level is high, and the frequency of client snacking is high, remineralization cannot take place and the start of dental caries may occur.

71
Q

How does saliva serve as protectant against decay?

A
  1. Physical protection: assists in the removal of sugars from the mouth
  2. Chemical protection: Neutralizes and buffers acids in bacterial plaque
  3. Antibacterial protection: contains antibacterial properties

Q

Because dental plaque biofilm is not easily seen; it can be difficult for patients to realize it is there. What can you use to make your oral hygiene instructions more effective?

A

a disclosing agent

158
Q

This method is useful for all types of dental conditions, especially periodontal diseases. With bristles. Pointed at a 45-degre angle into the gingival sulcus, the brush is vibrated gently back and forth about 10 times. The brush is then moved forward and the vibrations repeated.

A

Bass Method

159
Q

This method is useful for removing biofilm without reaching the sulcus. The brush is placed above the free gingiva with the bristles pointed toward the apices. Light pressure is exerted and the brush is drawn toward the occlusal surface using a rolling stroke.

A

Rolling Stroke Method

160
Q

This method is useful for patients with severe loss of interdental papilla height, fixed prosthetic appliances and previous gingival surgery. The rolling stroke method is completed first. Then the bristle tips are directed toward the occlusal or incisal surface. The handle is rotated, flexing the bristles and bringing them into contact with the interdental tissue and exposed proximal surfaces. The handle of the brush is vibrated with a slow, circular motion.

A

Charters

161
Q

This method is useful for patients for cleaning cervical areas, and for stimulation and massage of the gingiva. It works well in areas of recession and proximal surfaces. The brush ends are placed partly on the ginigva and partly on the cervical area of the tooth and directed slightly apically and angled 45 degrees. The bristles are vibrated in a rotary motion over the gingiva and rolled over the tooth making some bristles reach interproximally

A

Modified Stillman

162
Q

This method is useful for small children or others with poor manual dexterity. The teeth are occluded.
Then, lightly press the bristles against the posterior teeth and the gingiva. The brush is moved in a
circular motion, using circles of large diameter. The circular motion is continued, and the brush is
slowly motioned toward the anterior until all facial surfaces have been brushed. With the mouth open,
use an in and out stroke on the maxillary and mandibular lingual surfaces.
