Quiz #2 Flashcards
(59 cards)
What is periodontal debridement?
-Removal of plaque, bacteria, endotoxins, and hard calcus from teeth
What is the goal of periodontal debridement?
-Prevent/stop infection and restore oral soft tissue health
What is the purpose of the modified pen grip? Explain.
-provides good fingertip tactile sensitivity
-precise instrument control
What instrument do you use the modified pen grip?
-hand scalers (not morse)
-Probe and explorer
What are the 3 parts of the handle? Describe each
-Handle: The part of the instrument held
-Shank: The area of the insturment between the working area and the handle, subdivided into working and terminal
-Working area: Subdivided into heel, tip, middle or toe. Has a flat face and 1 or 2 cutting edges on either side of the face
Describe the sickle scaler.
-Angle cutting edge of scaler to scrape plaque and tartar off teeth
-Curved or straight
-Has a triangular cross section and tapers into a sharp pointed tip with two cutting edges on either side of the face
What are the uses for the sickle scaler? Towards or away from the gum line?
-Removing calcus from pits, fissures, developmental grooves, and interproximal spaces
-Aways pull away from the gumline
Describe the morse scaler.
-Smaller than the sickle scaler
-held in pencil grip
When would you use the morse scaler?
-used straight onto the tooth to clean ridges
Describe curettes.
-scalers that are used for subgingival calculus removal and root planning
When do you use a curette?
-removal of calculus from the sulcus or adhered to the tooth root
How can you tell the difference between a curette and sickle scaler?
-Curettes will have a rounded edge that can go under the gingiva without causing harm
What are the 2 types of curettes? Which is used most in vet med?
-Gracey
-Universal (used in vet med)
Describe the periodontal probe.
-Has no sharp edges, used to measure the dept of the gingival sulcus, gingival recession or hyperplasia, diameter of oral masses and any other oral structures
How do you use the periodontal probe?
-Inset the probe in between the gingiva and root surface, parallel to the long axes of the tooth. Walk the probe along the circumference of each tooth at least four times
What are normal sulcus depths for dogs? Cats?
-Dogs:1-3mm
-Cats:0.5-1mm
Describe the shepherd’s hook/explorer.
-Used to detect calculus, explore cavities, and exposed pulp chambers
-Has a sharp tip only
What does the shepherd’s hook help you to feel?
-Abrasions
-Attrition
What is furcation?
-The area where the tooths roots leave/enter the bottom of the tooth
Describe the stages of furcation.
-stage 1: Furcation exposure with mild amount of alveolar crest loss
-Stage 2: ½ of furcation and alveolar crest loss
-Stage 3: Alveolar crest completely lost, Furcation fully exposed
What is the tooth mobility scoring index?
-Seeing how much the tooth is able to move
Describe the stages of the mobility scoring index.
-Stage 0: Physiologic movement up to 0.2mm
-Stage 1: Mobility is increased in any direction other than axial over a distance of more than 0.2mm and up to 0.5mm
-Stage 2: Mobility is increased in any direction other than axial over a distance of more than 0.5mm and up to 1mm
-Stage 3: Mobility is increased in any direction other than axial over a distance of more than 1mm or any axial movement
Describe elevators
-Serves as a wedge placed between the root and the bone to stretch and break the periodontal ligament
Describe periosteal elevators.
-Used to create a mucoperiosteal flap
- Cuts away the periosteum to release the gingiva and mucosa
-reveals alveolar bone underneath
