- Question
- Answer
- Side 3

- What is oligodontia?
- decreased number of teeth
- Under what conditions should supernumary teeth be extracted?
- when they cause crowding of the normal dentition
- What is the preferred tx for retained deciduous teeth?
- overly retained deciduous teeth should be treated by gentle extraction
  
  deciduous teeth and the permanent tooth should not be present at the same time
  
  overly retained deciduous teeth can lead to malocclusion of the permanent dentition.
- What is prognathism?
- a forward relationship of one jaw relative to the other jaw. Usually pertaining to the mandible rather than the maxilla.
- In which breeds is a relative mandibular prognathism considered a normal bite?
- bulldogs, boxers
- What is brachygnathism?
- excessive shortness of one or both jaws
- What is wry bite?
- one side of the jaw, either mandible or maxilla is shorter than the other (one-sided brachygnathic bite
- What is "spear bite" & what breed may be genetically predisposed?
- = rostromesial inclination of maxillary canine teeth
  
  defect is hereditary and most frequently seen in Shetland Sheepdogs and can be orthodontically corrected with brackets, wires and elastics
- What are base narrow canine teeth?
- = lingual displacement of permanent mandibular canines
  
  frequently a result of overly retained deciduous canine teeth which may result in traumatic occlusion of the tips of the mandibular canine teeth with the palate
- What are some common clinical presentations of periodontal dz?
- mobile teeth
  periodontal and periapical abscesses with secondary facial swelling
  gingival recession
  mild to moderate gingival hemorrhage
  deep periodontal pockets with secondary oronasal fistulas resulting in a secondary rhinitis
- What are dental caries? What teeth are most commonly affected?
- Demineralization and loss of tooth structure
  
  Deep lesions cause pulpitis & pain
  
  Teeth most commonly affected by caries: maxillary 1st molar, mandibular 1st & 2nd molars
- What is the tx for dental caries?
- x-ray affected tooth, remove dental caries & restore tooth or extract tooth
- What is dental attrition?
- The abnormal process of teeth wearing rapidly
  
  diet and chewing habits account for most cases of severe attrition
- What teeth are most commonly fractured in dogs?
- canines, maxillary 4th premolar
- How can you determine if there is pulpal exposure in a fractured tooth?
- a dental explorer is used to determine if the pulp has been exposed
- What are some tx options for pulpal exposure?
- Vital Pulpotomy: utilized in recent fractures and fractures in young animals
  
  Conventional endodontic therapy: most common form of pulpal therapy also known as conventional root canal therapy and involves removal of the entire pulp and placement of gutta percha in canal
  
  Surgical endondontic therapy: utilized when apical resorption is present and tooth must be filled through the crown and apex of the affected tooth
  
  Extraction
- What are some possible sequela to pulpal exposure?
- acutely: extreme pain
  "pulp polyps": granulomatous tissue overlays pulp
  bacterial pulpitis
  pulp necrosis
  if chronic: periapical lysis, osteomyelitis, mucosal drainig tracts, rhinitis, ocular signs
- What are some potential sequelae assoc. w/ failure to tx fractured teeth?
- Abscess formation
  Cutaneous and mucosal fistula formation
  Chronic rhinitis associated with oronasal fistula formation
  Ocular signs
