Flashcards in Carnivore dental Deck (56):
What is the normal periodontal depth in a cat?
What is the normal depth of the periodontal pocket in a dog?
What may a greater periodontal depth than normal be indicative of?
Disease in the periodontal space, e.g. periodontitis
What does R stand for when completing a dental chart?
How is enamel defect coded for by a dental chart?
What does RT stand for on a dental chart?
Retained temporary tooth
What does CA stand for only a dental chart?
What 4 factors are examined and graded when performing a dental examination?
Why are some dog breeds more prone to dental disease than others?
Retained deciduous teeth into adulthood
What kind of teeth do dogs and cats have: hypsodont or brachydont?
At what age do deciduous teeth begin erupting in both species?
Which teeth are not present in the deciduous dental formula of both species?
At what age do permanent teeth begin erupting?
Which of the premolars in both species possesses only a single root?
1st maxillary premolar
How does the first maxillary premolar differ from the others in both species?
This is the only tooth of the premolars to have a single root, compared with the 2 diverging roots of the other premolars
Which teeth in dogs are single rooted unusually?
1st maxillary premolar
1st mandibular premolar
How many deciduous teeth does a kitten have?
26 deciduous teeth
What is the deciduous dental formula for kittens?
2(I 3/3 C 1/1 P 3/2) = 26 teeth
When do the deciduous teeth in a kitten erupt and finish emerging?
Deciduous teeth begin emerging at 4wks and have come through by 8wks
At what age do the cats' permanent dentition begin emerging?
Incisors at 3-4mo
Which species has a degree of grinding surface to their occluding aspect of their molars? Why
Dogs have a grinding surface to their molars as their diet is not as specialised as cats
What is the role of the periodontal ligament?
Permits tiny movements of teeth during mastication
Which species has the smaller periodontal pocket?
What is the root covered by?
What material covers the crown of teeth?
Where is the periodontal ligament found?
Between the tooth and its alveolar socket
What layer is the pulp cavity deeper than?
What feature of teeth makes them difficult to extract?
Many teeth roots have a bulbosity at the end which can complicate extractions
What are the alveolar sockets lined by?
A cribriform plate
How is the cribriform plate identified radiographically?
As the lamina dura
What does disruption of the lamina dura indicate?
Which teeth in a dog have 2 roots?
Maxilla: 06 07 10
Mandible: 06, 07 08 09 10
Which teeth have 2 roots in a cat?
Mandible: 07 08 09
What do maxillary teeth 08 and 09 have in common in a dog?
They both have 3 roots
Which teeth in a cat have 3 roots?
08 maxillary teeth
Why are cats teeth more complicated to extract?
Their periodontal space is considerably smaller
Their roots are smaller
Which teeth are single-rooted?
What is the name of the numbering system employed for the dental arcades?
Triadan numbering system
How many teeth are there on each arcade in a dog?
10 on each upper arcade
11 on each lower arcade
What is the danger posed to cats by inflated endotracheal tubes?
Cats have highly sensitive larynxes that can go into spasm with an inflated tube
In which species is an ET tube fitted and the cuff inflated?
Dogs - due to sensitive nature of cats' larynxes
What should be inserted into the pharynx and regularly changed to prevent blood or debris from entering the trachea?
What vital sign should be monitored in particularly when dental procedures or exams are being performed?
Body temperature as this can rapidly fall during dentals
What is the difference between calculus and plaque?
Calculus is mineralised plaque
Plaque is a sticky, light colour biofilm that initially contains gram + aerobes
What is periodontal disease commonly caused by?
Subgingival plaque and calculus
What components are graded in a canine dental chart?
What additional section is present on a feline dental chart?
Why is adequate water spray crucial when using a scaler?
To prevent heating and damaging of teeth
How is damage to the enamel prevented when using a dental scaler?
Scaler must be kept moving at all times
Flat of tip must be used for each tooth
What is the aim of scaling?
To remove calculus present above and below gumline, hence leaving behind a smooth surface to inhibit future buildup
If there is a periodontal pocket >2mm depth, what piece of equipment should be used?
A hand curette
How many places should the periodontal pocket be assessed?
6 places (3 buccal, 3 lingual)
What is used to perform polishing of teeth?
Fine grade prophy paste
How long should be spent scaling each tooth?
No more than 2s
What is the maximum period of time that should be spent polishing a tooth?
