Perio Week 10 Flashcards
Necrotizing gingivitis limited to
Gingival tissues
Necrotizing perio
Necrosis of gingival tissues, PDL, and alveolar bone
Necrotizing stomatitis
Severe necrosis extends beyond gingiva to other parts of the oral cavity (cheek, tongue palate)
Alternative terminology of necrotizing peril
Trench mouth
ANUG
Vincent infection
Necrotizing ulcerative gingivostomatitis
Necrotizing period disease is very painful, the gingival tissues appear
Fiery red with spontaneous bleeding
Necrotizing perio disease rapidly escalates and produce loss of periodontal attachment within
Days
Necrotizing perio disease gives the appearance that papillae and gingival margins have been
Punched out or cratered
Pseudomembrane refers to
A gray layer of tissue that covers the necrotic areas of the gingiva
Systemic signs and symptoms of necrotizing perio disease
Swollen lymph nodes (submand and cervical)
In severe cases: fever loss of appetite, increased pulse rate, malaise
Predisposing factors of NPD
Compromised host immune response
Poor oral self care
Emotional stress
Fatigue
Alcohol use
Smoking
Mean age of NPD in industrialized countries is
22-24 years old
Mucogingival conditions are assessed through clinical examinations for
Recession
Frenum pulling of gingiva
Width of attached gingiva
Attached gingiva formula: to calculate the width of attached gingiva at a specific site
Measure the width of the gingiva (from margin to Mucogingival junction)
Subtract the probing depth from total width
Adequate attached gingiva
Greater than 1mm
Inadequate probe depth is less than
1mm
What may contribute to inadequate attached gingiva
Maxillary and mandibular frenum pull
Buccal frenum
Recession
Bruxism
Ortho
Age
Lip/tongue piercing
Gingival phenotype refers to
Clinical observation of variation in the thickness and width of facial keratinized tissue
Periodontal biotype describes
Individual differences in bone and soft tissue that make up the periodontium as well as tooth form
3 main biotypes
Thin scalloped
Thick flat
Thick scalloped
Research shows that plaque associated inflammation may result in
Deep periodontal pockets with a thick flat biotype and into gingival recession in a thin scalloped biotype
Thin scalloped biotype is slender
Triangular shaped tooth crowns
Clear thin delicate gingiva /thin alveolar bone
Thick flay biotype; what shape tooth crowns
Square shaped
Thick fibrotic gingiva: thick alveolar bone
Thick scalloped biotype has pronounced gingival scalloping; what kind of fibrotic tissue
Thick fibrotic tissue
Narrow zone of keratinized tissue
Gingival recession is the most common Mucogingival deformity and is characterized by
Apical displacement of gingival margin with respect to CEJ
-attachment loss with root exposure
Risk factors of gingival recession
Thin periodontal biotype
Absence of attached gingiva
Reduced thickness of alveolar bone due to abnormal tooth position
-Marginal recession but does not extend to MGJ
-no loss of bone or soft tissue in interdental area
-Complete root coverage is obtainable
What miller recession classification?
Class I gingival recession
Class II miller gingival recession same as class one miller except
Marginal recession extends beyond MGJ
-marginal recession extends beyond MGJ
-bone and soft tissue loss in interdental
- may have tooth malpositioning that prevents coverage of certain roots
Miller classification?
Class III gingival recession
T/F. Class IV miller gingival recession is the same as class III miler just more extreme and crater like
True
RT1 gingival recession with no loss of Interproximal attachment. Most likely associated with
Traumatic tooth brushing
RT2 gingival recession with loss of Interproximal attachment most likely associated with
Periodontitis associated horizontal bone loss
RT3 same as RT2 but with Interproximal attachment loss greater than buccal loss associated with
Infrabony defects
Aberrant (abnormal) frenum can contribute to a
Diastema
Recession
Muscle tension
Non carious cervical lesions (NCCL’S)
Are defined as dental tissue lost at or near the CEJ and not related to?
Tooth decay
Traumatic occlusal forces are forces that exceeds?
Adaptive capacity of periodontium and or the teeth
(Excessive wear, occlusal trauma, fracture)
Primary occlusal trauma occurs in the presence of?
Normal bone level
Normal attachment level
Excessive occlusal forces
Secondary occlusal trauma occurs in the presence of
Bone loss
Attachment loss
Normal/excessive occlusal forces
Crowding and overhanging restorations can contribute to
Periodontitis
What procedures may cause recession and loss of clinical attachment
Indirect restorations (crowns, bridges)
Ortho treatment
