mucogingival deformitites Flashcards
Whats the whole purpose of correcting mucogingival defects?
to obtain the most attached tissue possible which improves hygiene, function and esthetics
defects that require tissue removal are…..
crown lengthening, esthetic surgical correction, aberrant frenums
what is the most prominant mucogingival defect you will see?
root recession
is attached gingiva keratinized?
no, the sulcus is not keratinized
how do you calculate the width of the attached gingiva?
subtract the depth of the sulcus from distance between crest of gingival margin and the mucogingival junction
would you want a wider or narrower zone of attached gingiva around teeth that are used as abutments for dentures?
wider.
what causes mucogingival defects on tooth roots?
ortho treated teeth
trauma
displacement of gingival margin from CEJ( clinical vs anatomical crown)
are longer and narrower teeth associated with more or less bone loss?
more
symptomology of mucugingival defects can include…
periodontal disease leading to bone loss
irritation of marginal tissues due to limited amount of keratinized tissues
exposure of tooth leading to sensitivity
esthetic concern for patient
___ % of people 65 and older, and 50% of people aged 18-64 will have one or more sites with gingival recession
88%
whats the most common etiologic factor associated with gingival recession?
malpositioned teeth and toothbrush trauma
The index of recession by smith is used to measure what?
horizontal and vertical loss of attached gingiva
nordland and tarnows system is used to measuer what?
loss of papillary height
millers classification of gingival recession classes 1-4
1: recession that doesnt extend to the MGJ
2: recession extends to or beyond MJG with no attachment loss in interdental area
3: recession extends to or byond MHJ with periodontal attachment loss in interdental area
4: recession extends to or beyond MGJ with severe bone and soft tissue loss in interdental area
T/F, treating abrasive defects with composite will solve the Pts esthetic s due to long tooth?
F, it needs MGJ surgery where the tissue is pulled down to where the CEJ should be.
