ETIOLOGY OF PERIODONTAL DISEASE

Periodontal disease comprise a group of inflammatory condition of the supporting tissues of the teeth that are caused by _______

True or False: Periodontal health is considered to a state of balance when the bacterial population coexists with the host and no irreparable damage occurs to either the bacteria or the host tissue

Consists of a mat of densely packed, colonized, and colonizing microorganisms that grow on and attach to the tooth

Free floating or loosely attached between the soft tissue and teeth

• Bacterial plaque

• Acquired pellicle

• Calculus

• Food debris

• Materia alba

 Primarily a protein film that forms on erupted teeth and can be removed by abrasives

 Quickly reforms after being removed

 Not removed by forceful rinsing

• Bacterial plaque

• Acquired pellicle

• Calculus

• Food debris

• Materia alba

 Calcified plaque that is usually covered by a soft layer of bacterial plaque

• Bacterial plaque

• Acquired pellicle

• Calculus

• Food debris

• Materia alba

 Food matter that is retained in the mouth

• Bacterial plaque

• Acquired pellicle

• Calculus

• Food debris

• Materia alba

 (literally, white matter)

 A soft mixture of salivary proteins, some bacteria, many desquamated epithelial cells, and occasional disintegrating leukocytes

 Usually flushed off with forceful water spray

• Bacterial plaque

• Acquired pellicle

• Calculus

• Food debris

• Materia alba

________ is the principal aetiological factor in virtually all forms of periodontal disease. Periodontal damage is almost certainly the direct consequence of colonization of the gingival sulcus by organisms within dental plaque.

What causes Periodontal disease?

• Plaque

• Saliva
