Periodontics Flashcards
What is the definition of a periodontal abscess?
Localised, acute exacerbation of a pre-existing pocket
What is the definition of a periapical abscess?
Localised collection of pus around apex of a non-vital tooth due to pulp necrosis
How does a periodontal abscess present?
Usually vital
Pain on lateral movements
Usually mobile
Loss of alveolar crest
Associated with generalised horizontal bone loss
How does a periapical abscess present?
Non-vital
TTP vertical
May be mobile
Loss of lamina dura
What is the definition of occlusal trauma?
Tooth mobility which is progressively increasing or tooth mobility with symptoms and radiographic evidence of increased pdl width
What is the definition of periapical periodontitis?
Periodontal disease that has reached the apex of the tooth
How does periapical periodontitis present?
Resorption of alveolar bone
Loss of attachment
How does chronic gingivitis present?
Bleeding on probing
Gingival inflammation
False pockets due to oedema
What are the contraindications for periodontal surgery?
Poor OH/plaque control
Smoker
What is the purpose of periodontal surgery?
Arrest disease by gaining access to complete RSD and regenerate lost periodontal tissues
What are the indications for periodontal surgery?
Post non-surgical periodontal treatment
Excellent OH
Inflammation resolved
Pockets >5mm persist
What are the benefits of open flap for periodontal surgery?
Helps gain access to root surface in persistent pockets
What are the benefits of a gingivectomy?
Improves aesthetics
Facilitates plaque control
What are the reasons for a gingivectomy?
Reduces overgrowth
Pseudopockets
Areas with difficult access
Gingival fibrzomatosis
