Oral Diseases and Dental Specialties: Pedodontics Flashcards
What is the treatment of dental disease in puppies and kittens?
Pedodontics
What is the absence of teeth?
Anodontia
Why might teeth be missing in a kitten or a puppy?
Because they never developed in the first place
Slow to erupt
Were present and fell out
Which breeds are likely to retain their teeth in the bone subgingivally?
Boxers, pug, and dachshund
What do retained teeth lead to?
Formation of a dentigerous or follicular cyst
Known as “dentigerous cysts”
What are persistent primary teeth also called?
Retained, deciduous, or baby teeth
Do persistent teeth cause problems?
Yes, sometimes cause orthodontic and periodontal abnormalities
How can persistent primary teeth cause periodontal disease?
From plaque being trapped between the primary and adult teeth
When should a primary tooth be extracted?
As soon as possible after the adult tooth starts to erupt
What general rule applies to primary teeth?
There is no room for two teeth of the same type in the same mouth at the same time
What describes the process of extracting primary teeth to prevent orthodontic malocclusions?
Interceptive orthodontics
What is caused by mutations of a specific protein called dentin sialophophoprotein (DPP)?
Dentinogenesis imperfeca
What is necessary for the initiation of mineralization of dentin?
The protein dentin sialophosphoprotein
What do the teeth of patients that do not have DPP look like?
Their teeth are brittle, discolored, and are susceptible to fracture
What is the soft tissue covering a partially erupted tooth crown called?
The operculum
An accumulation of oral debris bacteria beneath the tissue or biting the operculum with the opposing tooth leads to inflammation of the soft tissues, which is called what?
Pericoronitis or operculitis
What is an inherited condition that occurs primarily in West Highland white terriers and is when non-neoplastic bone forms in the region of the temporomandibular joint and occasionally extends into the mandible?
Cranial Mandibular Osteodystrophy
How do you treat Cranial Mandibular Osteodystrophy?
Patients are treated symptomatically for pain, which usually lessens as the patient gets older
Mandibular periostitis ossificans occurs in what dogs?
Immature large breed dogs
What does mandibular periostitis ossificans cause?
A unilateral swelling of the ventral portion of the mandible, caused by the formation of periosteal new bone, which is thought to be an inflammatory condition that spontaneously disappears
What happens if a fractured primary tooth is left untreated?
It may result in abscessation
What can abscessation cause?
A defect in the enamel production known as enamel hypoplasia and possibly a fistula
What can supernumerary teeth cause?
Malpositioning and noneruption of other teeth
Severe plaque accumulation
Predispose to periodontal disease owing to the lack of normal cleaning action.
How do you treat an animal with supernumerary teeth?
Extraction after intraoral radiographic evaluation to differentiate between deciduous and permanent teeth
How do you differentiate between deciduous and permanent teeth?
Deciduous teeth are smaller than their permanent counterparts
The roots of deciduous teeth are relatively long in relation to the crown
What are peg teeth and where do they generally occur?
Abnormally formed supernumerary teeth
Occur in the canine and incisor regions
Supernumerary teeth may also result from the formation of what?
A third set of teeth
The primary teeth fall out at the normal time two new rows of teeth (outermost being the adult teeth) grow
What is the joining of two developing teeth that have different tooth buds?
Fusion
What is it called when a tooth bud is partially divided in the attempt to form two teeth?
A gemini tooth
How do you differentiate between fusion and gemini teeth?
A radiograph is necessary
What does a fusion tooth look like on a radiograph?
Two roots will be seen with fused teeth
What does a gemini tooth look like on a radiograph?
One root with twin crowns
What is a dilacerated root?
An abnormally formed root
How is a dilacerated root caused?
Trauma during the tooth’s development or a genetic condition
