How to calculate the CDD in a dog? - briefly
To calculate the CDD (Corrected Dosage Diagram) for a dog, you need to consider both the dog's weight and the total dose of medication administered. The formula used is: CDD = Total Dose / Weight of Dog. This calculation helps ensure that the dosage is appropriate for the size of the animal, preventing underdosing or overdosing.
How to calculate the CDD in a dog? - in detail
Calculating the Canine Dental Disease (CDD) index in dogs is a critical component of oral health assessment and management. The CDD index, established by the American Veterinary Dental College, is a standardized system used to evaluate the severity and extent of periodontal disease in canines. Here's a detailed step-by-step guide on how to calculate the CDD:
-
Examination Under Anesthesia: The first step involves a thorough examination of the dog's mouth while under general anesthesia. This ensures safety and allows for a comprehensive assessment without causing discomfort to the animal.
-
Probing Depths: Use a periodontal probe to measure the depth of pockets between the teeth and gums. The probe is inserted gently into the sulcus (the space between the tooth and gum) at six specific sites around each tooth: mesiobuccal, buccal, distobuccal, mesiolingual, lingual, and distolingual.
-
Recording Pocket Depths: Record the probing depths in millimeters for each site. The CDD index is based on the deepest pocket measured around a tooth.
-
Assigning Scores: Assign a score to each tooth based on the deepest probing depth found:
- Score 0: No signs of dental disease (pocket depth ≤ 3 mm).
- Score 1: Gingivitis (pocket depth > 3 mm but ≤ 4 mm).
- Score 2: Early periodontal disease (pocket depth > 4 mm but ≤ 6 mm).
- Score 3: Advanced periodontal disease (pocket depth > 6 mm).
- Score 4: Severe periodontal disease with significant bone loss and mobility.
-
Calculating the CDD Index: Sum up all the scores assigned to each tooth. Divide this total by the number of teeth scored to obtain the average score, which is the CDD index.
-
Interpreting Results: The resulting CDD index provides a numerical value representing the overall severity of dental disease in the dog:
- CDD 0-1: Mild dental disease.
- CDD 2-3: Moderate dental disease.
- CDD 4-5: Severe dental disease.
-
Documentation and Treatment Planning: Document the CDD index along with specific findings from the oral examination. Use this information to develop a comprehensive treatment plan, which may include professional dental cleaning, antibiotics, and other therapies as needed.
By following these detailed steps, veterinary professionals can accurately calculate the Canine Dental Disease index, enabling them to provide appropriate care and improve the oral health of their canine patients.
