1. When interpreting dental radiographs, which of the following findings is most consistent with periapical disease?
Increased opacity surrounding the root apex
Lucency surrounding the root apex with loss of lamina dura
Widening of the periodontal ligament space in the coronal third only
Hypercementosis at the root apex
2. True or False: Tooth resorption in feline patients is always visible on oral examination without the use of dental radiography.
True
False
3. Which of the following best describes the appropriate technique for a rostral mandibular nerve block in a canine patient?
Inject adjacent to the mental foramen at the level of the third premolar
Deposit anesthetic at the mandibular foramen on the medial aspect of the ramus
Inject at the infraorbital foramen just caudal to the upper third premolar
Place the needle directly into the periodontal ligament space
4. A 6-year-old dog presents with Stage 3 periodontal disease affecting the maxillary fourth premolar. Radiographs reveal 40% horizontal bone loss with an otherwise intact root structure. What is the most appropriate treatment consideration?
Extraction is the only option at this stage
Periodontal therapy including subgingival scaling, root planing, and guided tissue regeneration may be indicated as an alternative to extraction
Polish and recheck in six months
Crown amputation with vital pulp therapy
5. When extracting a multi-rooted tooth, which of the following is the correct first step after flap elevation?
Apply forceps and rotate the tooth to luxate
Section the tooth at the furcation to separate roots before extraction
Use an elevator apically to luxate the entire tooth as a unit
Pack the socket with absorbable gelatin sponge before extraction
6. True or False: Dental radiographs should be taken after every extraction to confirm complete root removal.
True
False
7. Which suture pattern is most commonly recommended for closure of a simple gingival flap following tooth extraction in veterinary patients?
Continuous locking pattern with non-absorbable monofilament
Simple interrupted pattern with absorbable monofilament
Horizontal mattress with non-absorbable braided suture
