What are the main benefits of veterinary dentistry according to the notes?
Good medicine (relieves pain, extends life) and a profitable niche/business.
Which organs are most susceptible to damage from periodontal bacteria due to high blood flow?
Lungs, liver, and kidneys.
A medium-proportioned head; examples include Poodles, Corgis, Beagles, Labradors, and Domestic Short Hair cats.
Mesaticephalic skull type
Short, wide head; often with crowded and rotated premolar teeth; examples include Boxers, Pugs, Bulldogs, and Persian cats.
Brachycephalic skull type
Long, narrow head; examples include Collies, Greyhounds, Borzoi, and Seal Point Siamese cats; malocclusions common in caudal mouth.
Dolichocephalic skull type
What is the maxilla hard palate and what are the ridges called?
The roof of the mouth made of hard bone; ridges are called rugae palatinae.
What is the incisive papilla and where is it located?
A small papilla located behind the central incisors on the hard palate.
What do the nasopalatine ducts do and where do they lead?
Exit on each side of the hard palate and connect to the vomeronasal organ and amygdala, involved in scent and emotion.
What separates the oral cavity from the pharynx?
The soft palate.
What is the area where the two jaws join?
The lateral palatine fold.
What does the oral mucosa line from to?
The mucogingival line to the end of the lips.
What are the components of the attachment apparatus/periodontium?
Gingiva, Cementum, Periodontal Ligament, and Alveolar Bone.
What are the basic tooth components?
Crown, Cervical portion (neck), and Root.
What is enamel and its inorganic content percentage?
The hard outer layer covering the crown formed by ameloblasts; 96% inorganic hydroxyapatite crystals.
What is the dentin composition in terms of inorganic vs organic material?
Approximately 70% inorganic and 30% organic.
Who produces dentin?
Odontoblasts
Name the three types of dentin.
Primary, Secondary, and Tertiary dentin.
What is the outer covering of the tooth root and its hardness relative to bone?
Cementum; hardness similar to bone; produced by cementoblasts; can regenerate.
What does the pulp consist of?
Pulp canal, pulp chamber, root canal; contains blood vessels, lymphatics, nerves, and cells.
What are the main tooth types?
Incisors, Canine, Premolars, Molars
Having all the teeth of the same form; fish, reptiles, sharks, dolphins
Homodont
Having teeth of different shapes, as molars, incisors, etc.
Heterodont
An animal in which permanent teeth do not have a temporary precursor; Dolphins and most rodents
Monophyodont
Having several sets of teeth formed in succession through life
Polyphyodont
Having 2 dentitions, a deciduous and a permanent
Diphyodont
What are brachydont and hypsodont crown types
Brachydont: short crowns (dogs, cats, primates); Hypsodont: long crowns (horses, cows).
How is normal occlusion described in the canine/feline dental exam notes?
Scissors bite; mandibular teeth contact the palatal side of maxillary teeth; canines fit between the lateral incisor and maxillary canines; premolar cusps intermesh; mandibular teeth about 1/2 tooth in front; maxillary premolars do not contact mandibular premolars.
What defines Class I malocclusion and its subtypes?
Overall normal occlusion but one or more teeth not anatomically correct; includes distoversion, mesioversion, buccoversion, linguoversion, labioversion, crossbite; rostral/caudal variants.
What characterizes Class II malocclusion?
Mandible shorter than normal; can cause adult canines and incisors to contact the hard palate; may cause ulcers.
What characterizes Class III malocclusion?
Maxilla too short or mandible too long; mandibular prognathism; can lead to excessive wear and abnormal incisor contact; maxillary brachygnathism with crowding.
Measures pocket depth
AL Probe
Checks surface hardness and smoothness
Explorer
What is the normal periodontal pocket depth for dogs?
1-3mm
What is the normal periodontal pocket depth for cats?
½ -1mm
The area of bone loss at the branching point of a tooth root
Furcation
What consists a complete Dental Prophylaxis?
Oral cavity exam
Gross and Subgingival calculus removal
Probing
Missed plaque detection
Polish
Sulcus irrigation
Diagnostics
Final charting
What are the positional terms?
Labial, Buccal, Palatal, Lingual Mesial, and Distal
Pertaining to the tooth surface that faces the lip
Labial
Side of a tooth or gingiva facing the cheek
Buccal
The side of a tooth adjacent to (or the direction towards) the palate
Palatal
The direction towards the anterior midline in a dental arch
Mesial
The direction towards the last tooth in each quadrant of a dental arch, as opposed to mesial, which refers to the direction towards the anterior midline
Distal
What is the primary dental formula for canine?
i 3/3 c 1/1 p 3/3 X 2 = 28
What is the permanent dental formula for canine?
I 3/3 C 1/1 P 4/4 M 2/3 X 2 = 42
What is the deciduous (primary) dental formula for feline?
i 3/3 c 1/1 p 3/2 X 2 = 26
What is the permanent dental formula for feline?
I 3/3 C 1/1 P 3/2 M1/1 X2 =30
The absence of teeth
Anodontia
Failure to lose primary teeth as permanent teeth erupt
Persistent Primary/retained deciduous teeth
Process of extracting primary teeth to prevent malocclusions
Interceptive Orthodontics
Inflammation of non gingival periodontal tissue
Periodontitis
Inflammation of the mucosal lining of any structures in the mouth (refers to widespread oral inflammation
Stomatitis
A syndrome in cats characterized by resorption of the tooth by odontoclasts; believed to be caused by excess vit. C in the diet
Feline Tooth Resorption or Feline Odontoclastic Resorption Lesion
Thickening and excess growth of the gingiva as a result of chronic inflammation and the patient’s response to plaque
Gingival Hyperplasia
Presence of a tumor in the gingiva that contains mainly fibrous tissues; most common benign tumor in dogs; known as fibromatous epulis
Peripheral Odontogenic Fibroma
Known as acanthomatous epulis; composed of epithelial cells and classified as benign, but they do invade the bone
Peripheral Acanthomatous Ameloblastoma
•Locally and highly invasive
•Highly metastatic to lung, lymph nodes, and bone
•Prognosis is poor and recurrence is common
•Most common-dogs
•Rare- cats
Malignant Melanoma
•Nodular, gray-pink, irregular masses
•Invade the bone and cause tooth mobility
•Tumors in more rostral positions have better prognosis
•Most common- cats
•Second most common-dogs
Squamous Cell Carcinoma
•Occur at earlier age than others
•Metastasizes slowly, but aggressively invasive
•Requires wide surgical resection
•Guarded prognosis
•Second most common-cats
•Third most common-dogs
