Question Answer
What is the etiological agent of PD (periodontal disease)? (a) bacteria (b) plaquePlaque *Host response to plaque produces gingival inflammation
What is the primary determinant of need for professional dental therapy?Gingival Inflammation
What is the most important diagnostic tool in dentistry?Radiology
If the angle of your x-ray beam is too steep what will you get?Foreshortening *Elongation is when the angle is too shallow*
What will the shadow look like if it is correct?The correct bisecting angle - shadow will be the same size as the structure (tooth)
You see a tooth with one Giant Blood Vessel in the middle of the tooth and thin dentin and the tip of the root apex has not closed... is this a young or old dog?Young < 9 months **Adult 4yr or older, primary tissue in adult tooth is Dentin**
When does the tooth root apex close?not until 9mo
When you have a “complicated” crown fracture (pulp is exposed) what are the two things you can do?1) Extraction or 2) Root Canal
What is the Normal Sulcus (“Pocket”) Depth of the tooth for Cats? (a) 1.0-2.0mm (b) 0.5-2.0mm (c) 0.5-1.0mm (d)1.0-3.0mm0.5-1.0mm
What is the Normal Sulcus (“Pocket”) Depth of the tooth for Dogs? (a) 1.0-2.0mm (b) 0.5-2.0mm (c) 0.5-1.0mm (d)1.0-3.0mm1.0-3.0mm
If the pocket depth is less than 5mm how do you clean the sulcus?Closed Root Planing ( non surgical procedure, not opening gum tissue) ** Pocket Depth greater than 5mm OPEN ROOT PLANING **
What are the treatment options for Tooth Resorption?1) Extraction 2) Crown Amputation (Coronal) **30-50% of all cats will develop TR**
How can you distinguish gingivostomatitis from eosinophilic granuloma complex (They have similar signs)Can distinguish from GS ONLY** by Histology **Eosinophilic Granuloma Complex underlying etiology is Allergy
Secondary teeth erupt facially / buccally to the primary tooth... What is the exception to this?The upper canine tooth erupts mesially to the primary tooth (Situated toward the middle of the front of the jaw along the curve of the dental arch.)
how can steroids affect periodontal dz?collagen degradation, osteoporosis (increased destruction of perio tissues)
PD stage 2 is charaterized how?PD with <25% bone attachment loss
PD stage 3 is charaterized how?PD with 25-50% attachment loss
PD stage 4 is charaterized how?PD with >50 % attachment loss
Assessment starts with awake patient and the oral exam is... (what should you tell owners about this?)incomplete- must caution owners you are getting only a partial picture of oral disease
Assessment during Anesthesia would be a ___ ___ oral examCOMPLETE, EXTERNAL
parallel xray technique is used in...HUMANS but not in animals
what is the Bisecting Angle Technique:?Position Film, Tubehead, Patient so Parallel Technique is Simulated (Correct Bisecting Angle: Shadow (Radiographic Image) Same Size as Structure (Tooth))
Effective Treatment RequiresGeneral Anesthesia
When should teeth be extracted?pulpal penetration (when endodontics not possible), 50% root attachment loss, Grade III furcation exposure (poke explorer through from one side of tooth under the roots to the other), --retained deciduous, unerupted or impacted teeth, malocclusion causing trauma to apposing teeth or other tissues (when orthodontics not possible), tooth resorption, oronasal fistula
when do you need analgesia (in relation to extractions)Analgesia is Imperative Before, During and After Extractions
Some Malocclusions “Normal” for Certain Breeds (e.g., Bulldog, MAL-3): however, which malocclusions shouldnt occur in who?MAL-2, MAL-3 Should not Occur in Other Breeds (e.g., Retrievers): These are Skeletal Hereditary Defects, Dogs Should Not be Bred
Two Treatments for Non-Vital Teethextraction, root canal therapy
