VTT 242 Final Exam UPDATED ACTUAL
QUESTIONS AND CORRECT ANSWERS
Abnormal findings on dental radiography - CORRECT ANSWER root resorption, periapical
radiolucency, bone loss & fractures, retained root tips, unerupted teeth, caries, neoplasia
To increase grayscale contrast for radiographs of periodontal disease, we can _____ the kVp. -
CORRECT ANSWER increase
To improve black-and-white contrast for radiographs detecting tooth root resorption and caries, we
can _______ the kVp. - CORRECT ANSWER decrease
Advantages of digital radiography - CORRECT ANSWER reduced radiation exposure for
patient & operator, decreased time
Disadvantages of digital radiography - CORRECT ANSWER lack of a variety of plate sizes
Paralleling technique - CORRECT ANSWER Film is placed parallel to the teeth, x-ray beam is
directed at a 90-degree angle to the film and teeth
Bisecting angle technique - CORRECT ANSWER Film is placed as close to parallel the tooth
axis as possible, beam is directed perpendicular to line drawn between long axis of tooth and the plane
of the film, so that it "bisects" the angle formed between the film and the tooth; used for ANY tooth
for which a parallel technique is not possible
Occlusal technique - CORRECT ANSWER Film is placed between teeth on the occlusal
surfaces, beam is directed perpendicular to film
Common problems associated with bisecting angle technique - CORRECT
ANSWER foreshortening & elongation of tooth images
The occlusal technique is used to image the ___________________. - CORRECT
ANSWER incisors and canines
, The bisecting angle technique is used to image the _____________________. - CORRECT
ANSWER canines and premolars
The parallel technique is used to image the _________________________. - CORRECT
ANSWER premolars and molars
In dogs, the carnassial tooth is the _____ & ______. - CORRECT ANSWER fourth upper
premolar, first lower molar
Rongeur - CORRECT ANSWER also known as extraction forceps; used for tooth removal
Closed extractions are appropriate for __________. - CORRECT ANSWER single-rooted teeth
Surgical extractions are appropriate for __________. - CORRECT ANSWER multi-rooted teeth
Winged elevators - CORRECT ANSWER Used to disrupt periodontal ligament prior to tooth
extraction
Endodontics - CORRECT ANSWER treatment of the inside of the tooth; root canals
Exodontics - CORRECT ANSWER tooth extractions
Indications for exodontic procedures - CORRECT ANSWER periodontal disease, tooth
fracture, resorptive lesions
Contraindications for exodontic procedures - CORRECT ANSWER severe alveolar bone loss,
lack of client consent
Most oral tumors in cats are ________. - CORRECT ANSWER squamous cell carcinomas
(malignant)
