Objective
to determine patterns of alveolar bone loss (periodontitis) and other lesions evident on full mouth survey radiographs of cats
Design
Retrospective
147 cats
Procedure
Procedure—Full-mouth radiographs were evaluated
for evidence and severity of alveolar bone loss, odontoclastic resorption lesions (ORL), retained roots,
missing teeth, signs of endodontic disease secondary
to periodontitis, and apical resorption.
Cats with some degree of periodontitis
72%
What percentage of cats were missing teeth?
68%
Percentage of cats with ORL
67%
xxx had expansion of buccal bone
53%
cats < 4 not significantly more likely to have….
normal alveolar bone height
Prevalence of ORL increased with ….
age
cats > 13 yrs less likely than general population to have ….
moderate to severe periodontitis
Pure bred cats were or were not, more likely to have perio or ORL than mixed breeds?
were not
IN cats what type of bone loss is the most common radiographic pattern of bone loss
horizontal bone loss most common
When pure bred cats did have perio, was it more or less severe than the mixed breed cats?
more severe
Were the purebreds more likely to have FORL or Perio than mixed breed cats?
no
Cats with ORL were more or less likely to have alveolar bone loss?
more likely, severe focal vertical bone loss
What is generally accepted alveolar crest height from CEJ in cats?
within 1 mm of CEJ
In one study ___ % of cats had evidence of periodontitis and bone loss apparent on radiographs that was not clinically apparent or expected.
25.2%
What was the finding about buccal bone expansion in cats?
46% cats had alveolar bone>1 but <2 mm wide, 29% cats with normal alveolar bone height had mild buccal bone expansion
It has been stated that __% of dogs and cats over the age of 6 yrs have clinically important perio disease
85%
odontoclastic lesions were observed in ___% of cats in this study
67%
The higher prevalence of apical resorption in cats > 13 yrs is likely a reflection of increase in ___ with age.
FORL
