Vet tech tasks | dental prophylaxis, certain procedures that do not result in alterations in the shape, structure, or positional location of teeth in the dental arch. |
After appropriate training and under the direct supervision of the vet. you may: | take impressions,make models, chart veterinary lesions, take and develop radiographs, perform non-surgical subgingival root scaling and debridement, providing that they do not alter the structure of the tooth |
apical | toward the apex of the tooth root |
buccal | side of the tooth that faces the cheek (posterior teeth) |
cervical | toward the crown of the tooth |
distal | side of the tooth that is farthest from the midline of the maxillary or mandibular dental arch |
gingival | area of the tooth toward or at the gingival tissue |
incisal | biting surface of the anterior teeth |
interdental | area between two adjacent teeth in the same arch |
interradicular | area between roots of multirooted teeth |
labial | surface of the tooth nearest the lips, term used to describe the front surface of incisor teeth as opposed to the distal surface that faces the tongue |
lingual | side of the tooth that faces the tongue (applied to mandibular teeth) |
mesial | surface of the tooth that is closest to the midline of the maxillary or mandibular dental arch |
occlusal | the chewing surfaces of the caudal teeth |

Malocclusions | this refers to an abnormal tooth alignment |
class I | neutroclusion(displaced canines/ anterior cross bite/ posterior crossbite) |
class II | distoclusion |
class III | mesioclusion |
class I | top and bottom jaw lengths are of normal proportion but one or more teeth are tipped or rotated out of normal line of occlusion for example anterior crossbite |
class II | distoclusion, this can be a result of an abnormally long maxilla or an abnormally short mandible |

what is the treatment | remove the plaque and calculus from teeth and minimize reoccurrence, surgery, root debridement, subgingival currettage |
root debridement | removal of calculus from diseased tooth roots |
subgingival curettage | cleaning/debriding the gingiva covering the roots(foreign debris and granulation tissue |
technician note the key to prevention of periodontal disease | minimize plaque accumulation by means of proper diet, routine professional dental scaling and polishing, and daily teeth brushing or mouth rinse |
Caries means | Cavity which is uncommon |
Periodontal elevators | used to elevate the gingival mucosa to allow root planning, tooth sectioning, and creating gingival flaps |
Supragingival scalers | used on the exposed tooth to remove calculus above the gingiva (not to be used subgingivally) |
Dental extraction forceps | used to remove tooth from jaw and to clean heavy calculus off teeth. Do not apply too much pressure as you could fracture the tooth |
curettes are used | subgingivally to scale tooth roots and debride the gingival sulcus. they come in various angles to improve access to the tooth roots |
scaler is held | in a modified pen grasp. |
the stroke of a scaler | should be made through the wrist and not the fingers to avoid operator hand fatigue |

Proper positioning for a radiograph of the mandibular premolars and molars | lateral recumbency |
Positioning for a study of the mandibular incisors and canines | dorsal recumbency |
Positioning for the rostral mandibular premolars. Can also obtain a lateral view of the incisors and canine tooth | dorsal recumbency |
Positioning for the maxillary incisors | sternal recumbency |
Positioning for a study of the maxillary premolars. can also be used to obtain a lateral view of the maxillary incisors and canine tooth | sternal recumbency |
x-rays help determine | if extraction is necessary |
Technician Note: when one is learning positioning techniques for intraoral dental radiographs | it is easiest to place the dog or cat in sternal recumbency for views of the maxillary dentition, in dorsal recumbency for views of the anterior mandible, and in lateral recumbency for views of the mandibular premolars and molars |
Bisecting Angle Technique | this minimizes image distortion and produces an accurate image of the canine teeth on the dental film. In any ninty degree arc, there is one angle that will allow an x-ray beam to cast an accurate shadow of the tooth on the film |
what is the first thing to do for the bisecting angle | find the middle of the long axis of tooth and film |
what is the second thing to do for the bisecting angle | use the BA and x-ray head to create a nintey degree angle, no larger, no smaller |
three ways to reduce incidence of tracheal tears | 1) always disconnect the animal from the anesthesia circuit when repositioning them 2) minimize movement of the endotracheal tube 3) inflate the cuff just enough to stop anesthetic-gas leaks |
what is the longest to keep the ultra sonic scaler on the tooth | ten to fifteen seconds to avoid heat build up |
why is polishing teeth so important | prevent rapid plaque accululation following dental cleaning |
how long can the polisher be left on teeth | not longer than five seconds or thermal damage could result |
What are the advantages of using fluoride polishing pastes | fluoride strengthens enamel, decreases tooth sensitivity, has antimicrobial properties, decreases the rate of plaque reattachment |
what is the angle the sharpening stone should be kept at | an angle of one hundred to one hundred ten to the scaler face to maintain the proper shape of the instument |
where does the conical sharpening stone placed on the curette | rolled across the face of the scaler to remove wire edges |
materials used to take impression | rubber mixing bowl, spatula, impression trays, scoop, and water measuring cylinder |
