Periodontal disease is one of the most common problems in dogs and cats, and much of the hands-on dental work in a clinic is done by technicians. Most disease sits below the gumline, which is why charting and dental radiographs matter as much as cleaning.

Try each one before opening the answer. These come straight from the VetTech Pro question bank.
Question 1. What is the most common cause of halitosis in dogs and cats?
ARenal disease causing uremic breath, which is the leading cause in older dogs and cats
BA high dietary protein content that is fermented in the mouth
CPeriodontal disease, with volatile sulfur compounds made by anaerobic bacteria
DGastrointestinal disease with regurgitation of gastric contents
Show answer and rationale
Answer: C. Periodontal disease, with volatile sulfur compounds made by anaerobic bacteria
Owners frequently attribute bad breath to the stomach or to food. Where the mouth is genuinely healthy, renal disease, oral neoplasia and respiratory disease are worth considering as less common causes.
Question 2. For which teeth can the parallel radiographic technique be used in the dog?
AThe mandibular premolars and molars caudal to the symphysis
BAll maxillary teeth, because the hard palate keeps the sensor parallel
CThe maxillary canines only, with the sensor flat against the palate
DThe incisors in both arches, with the sensor placed behind the crowns
Show answer and rationale
Answer: A. The mandibular premolars and molars caudal to the symphysis
Only in the caudal mandible is there space to place the sensor parallel to the tooth without the palate or symphysis obstructing it. Everywhere else the bisecting angle technique is required.
Question 3. Why is the head positioned with the nose slightly downward during a dental procedure?
AIt improves access to the mandibular teeth and the lingual surfaces specifically
BIt reduces intracranial pressure during long procedures in older patients
CIt prevents the endotracheal tube from kinking at the back of the pharynx
DGravity drains water and debris out of the mouth rather than toward the pharynx
Show answer and rationale
Answer: D. Gravity drains water and debris out of the mouth rather than toward the pharynx
A head tilted upward pools irrigation fluid against the airway. The position must still avoid excessive neck flexion, which can obstruct the tube or compromise venous drainage.
