Q

What are the classifications for periodontal conditions as of the 2017 guidelines?

Please Give George Nine Percy Pigs Straight Past Meal Time Tonight.

A
  • periodontal health
  • Gingivitis
  • Gingival diseases and conditions (non dental biofilm induced)
  • Necrotising periodontal diseases
  • Periodontitis
  • Periodontitis as a manifestation of systemic disease
  • Systemic diseases or conditions affecting the periodontal supporting tissues

Q

what constitutes as gingivitis?

A
  • gum inflammation

Q

describe the mechanisms of biofilm induced gingivitis

A

supragingival plaque accumulates on teeth, inflammatory cell infiltrate develops in gingival connective tissue. junction epithelium becomes disrupted. allows plaque to migrate apically and increases sulcus depth. creates false pocket.

Q

When doing a BPE how would you diagnose gingivitis?

A

  • > 30% BOP =Generalised gingivitis
  • Presence of plaque retentive factors

Q

how does pubertal gingivitis come about?

A

Increased inflammatory response to plaque mediated by hormonal changes. In teenagers can progress to periodontitis.

Q

what are the 4 main distinguishing features of periodontitis?

A
  • Apical migration of junctional epithelium beyond CEJ
  • Loss of attachment of periodontal tissues to cementum
  • Transformation of junctional epithelium to pocket epithelium
  • Alveolar bone loss
