Flashcards in Dentistry Final Deck (94):
General sequence for complete Prophy
Oral cavity evaluated, large pieces of calculus removed, periodontal area probed for pocket depth & presence of subgingival calculus.
Subgingival calculus removed, teeth evaluated, degree of disease evaluated, further diagnostic tests performed.
Medium. Most common head type. Labradors and DSH, ex.
Short wide heads. Commonly results in crowded and rotated premolars.
Boxers, Persians ex.
Long narrow heads.
Collies, seal point Siamese ex.
Incisal and maxillary bones hold the teeth.
Portion of the roof of the mouth that consists of hard bone. Covered with mucous membrane w/irregular ridges called "Rugae palatinae"
Posterior portion of roof of the mouth, no underlying bone. Separates the oral cavity from the pharynx.
Lateral palatine fold or fauca
The area in which the two jaws join in the back of the oral cavity
Lower jaw. Covered by muscle and skin ventrally, mucous membrane becomes the gingiva at the mucogingival line
Hinge joint that joins mandible to maxilla
Vestibule of oral cavity
Part of oral mucosa between the cheeks or lips and the alveolar ridge (teeth/gingiva)
Part of the tooth above the gumline covered in enamel
Hardest substance in the body. Covers the crown of the tooth, above the gumline. Produced by ameloblasts.
Indentation close to the gumline where the enamel thins.
Also called cementoenamel junction or cervical line
Underneath the gumline, sits in the socket (alveolus)
Deepest part of the root.
Prophylaxis or Prophy
Prevention or protective treatment for disease
Where blood vessels and nerves enter the tooth
Apical delta (small channels)
Apical foramen (larger canals)
Tip or pointed prominence on the occlusal surface of the crown
Make up the bulk of the tooth, produced by odontoblasts
Innermost portion of the tooth. Lined by odontoblasts and contains nerves, blood vessels, different cells and fibrous tissue
Portion of the pulp chamber below the gumline
Hardening and tighter attachment of the epithelial tissue of the attached gingiva that makes it able to withstand chewing
The portion of gingiva that is not directly attached to the tooth or supporting structure
Free gingival groove
Slight groove between free and attached gingiva
Area between free gingiva and tooth when healthy and without a space
Space between free gingiva and tooth. Considered diseased tissue when periodontal disease is present
Less densely keratinized gingival tissue covering the bones
Structures that support the tooth: periodontal ligament, cementum, sharpey's fibers, alveolar bone
Fibrous structure that holds tooth In place in the socket
Material that can repair itself if damaged and attaches periodontal ligament ti the tooth
Bone of the jaw in which the tooth rests
Dental formula for puppy
2x(3/3 i, 1/1 c, 3/3p)=28
Time line for puppy teeth
Primary incisors erupt at 3-4 weeks, canines at 3 weeks; premolars from 4-12 weeks.
Fall out (exfoliate) about 1-2 weeks before adult teeth eruption
Adult dog dental formula
2x(3/3 I, 1/1 C, 4/4 P, 2/3 M)=42
Used for gnawing and grooming
Used for holding and tearing
Used for cutting and breaking up
Used for grinding
Dog adult teeth timeline
Incisors erupt at 3-5 months, canine & premolar at 4-6 months, molars at 5-7 months
Kitten dental formula
2x(3/3 i, 1/1 c, 3/2 p)=26
Kitten teeth timeline
Incisors erupt at 2-3 weeks, canines at 3-4 weeks, premolars at 3-6 weeks
Cat dental formula
2x(3/3 I, 1/1 C, 3/2 P, 1/1 M)=30
Cat adult teeth timeline
Incisors erupt at 3-4 months, canines at 4-5, premolars at 4-6 months, molars at 4-5 months
Dog teeth with one root
Incisors, canines, first premolar, mandibular third molar
(101-105, 201-205, 301-305, 311, 401-405, 411)
Dog teeth with 2 roots
Maxillary second and third premolars; mandibular second, third, and fourth premolars; mandibular first and second molars
(106, 107, 206, 207, 306-310, 496-410)
Dog teeth with three roots
Maxillary fourth premolar, and first and second molars
Cat teeth with one root
Incisors, canines, maxillary second premolar
101-104, 106, 201-204, 206, 301-304, 401-404)
Cat teeth with two roots
Maxillary third premolar, mandibular third and fourth premolars, mandibular first molar
(107, 207, 307-309, 407-409)
Cat teeth with three roots
Maxillary fourth premolar
Tooth in the cat with a varying number of roots
Maxillary first molar (feline)
The area in which the roots join the crown. In two-rooted it is bi-, in three-rooted it is Tri-
The direction toward the outside of the teeth
Toward the cheeks
Toward the middle of the mouth
Palatal for the maxillary
Lingual for the mandible
Side of the tooth closest to the center line of the dental arch
Side of the tooth farthest from the center line of the dental arch
Direction towards the crown
Toward the root of the tooth
Area between two teeth
The way teeth fit together. Cats and dogs have a "sectorial" one with chewing occurring on the sides of the teeth.
Anatomic numbering order
Right/left, maxillary/mandibular, ordinal number, type of tooth
Teeth missing in a cat
Maxillary First premolar, mandibular first and second premolars (105, 205, 305, 306, 405, 406)
Rule of four and nine
The canine tooth is always 04 and the first molar is always 09 regardless of how many teeth are actually in the mouth
Matrix of connective tissue consisting of bundles of strong collagenous fibers connecting periosteum to bone
The tissue that lines most of the oral cavity outside the mucogingival line, ends at the lips.

0-3 mm in dogs
0-1 mm in cats
A defect in enamel production
Junction between the gingiva attached to the underlying bone (attached gingiva) and the flap overlying the tooth (free gingiva)
