What is the Gingival Contour Plaque Index (GCPI)?
|
Recently introduced and validated method of measuring plaque accumulation in dogs
It focuses on plaque accumluated along the gingival margin |
|
|
Why does it appear important to measure the plaque accumulation along the gingival margin?
|
Plaque that accumulates in this area leads to gingival inflammation and, potentially, periodontitis
|
|
|
How was this study performed?
|
A 6-month plaque and gingivitis study was conducted to demonstrate the clinical research application of the GCPI and to ensure that documented quantification of plaque-reducing efficacy could be related to a reduction in gingivitis
|
|
|
What are the advantages of the GCPI?
|
Ability to quantify plaque accumulation in an awake dog with fewer research personnel and more efficient time use
|
|
|
Dental foods, treats, and chews have been reported to control plaque and calculus accumulation in companion animals
|
True
|
|
|
The study panel consisted of 14 beagle dogs (ages b/w 1.3-10.8 years)
|
Criteria for acceptance into this research panel were good overall health and full dentition
|
|
|
The investigation was conducted in 3 phases
|
Phase I: 3 day stratification study prior to assigning either to a test group or control group & to ensure that these groups were balanced for plaque accumulation
Phase II: oral health optimization period (cleaned teeth), to ensure all dogs began the study with clean dentition and minimal gingivitis Phase III: 6-month plaque and gingivitis assessment, comparing a commercially available test food possessing plaque-reducing efficacy (Hills t/d) |
|
|
How was the GCPI plaque graded?
|
A gingival contour probe (probe that is marked in mm, however curved compared to the straight ones we usually use), was used to measure the length of the gingival margin from the midpoint of the mesial surface, along the buccal surface, to the midpoint of the distal surface at the point where the gingiva contacts the tooth, as well as the length of the plaque along this contour
|
|
|
What teeth were scored in this study?
|
Maxillary I3, canine, P1-P4, and M1
Mandibular canine, P2-P4 |
|
|
What was the gingival grading system 0-3?
|
GI0: normal gingiva
GI0.5: mild inflammation, slight redness GI1: moderate inflammation and redness, no bleeding upon probing GI2: moderate inflammation with severe redness, bleeding on probing GI3: severe inflammation and redness, edema, ulceration and spontaneous bleeding |
|
|
What were the findings?***Do I have this right**
|
When evaluating GCPI before day 15 of the test and control groups (there was no real difference in the plaque accumulation of the groups, however after day 15 the plaque accumulation did become statistically significant (test group had less plaque)
With the gingivitis, there was a significant difference b/w the groups and the test group had lower scores of gingivitis |
|
|
If allowed to accumulate, plaque may lead to gingivitis and possibly periodontitis
|
An association has been demonstrated b/w periodontitis and systemic disease in dogs. Control of supragingival plaque can attenuate the development of gingivitis
|
|
|
Finding effective methods to accurately and reproducibly quantify plaque attenuation has lead to the development of plaque quantification protocols for use in animals
|
This was the purpose to evaluate if the GCPI was a good study model, and it appears to be
|
|
|
Several factors (age, breed, diet, general health, immunocompetence) contribute to the development and severity of periodontal disease
|
Progression of periodontal disease results in tissue distruction and tooth loss, and also may contribute to systemic diseases
|
|
|
Since plaque is the initiating cause of gingivitis and subsequent periodontitis, assessment of plaque reduction is a key step in determining efficacy of canine and feline dental health products
|
Plaque levels have been shown to achieve stable values in 1-2 weeks in dogs
