Pulp cavities help in determining age

Maxillary canine.

Labiolingual sections show various stages of development.

1. Crown complete; root partially completed with large pulp cavity, wide open at apical end.

2. Tooth almost complete, except for lack of constriction of apical foramen.

3. Canine of young individual with large pulp cavity and completed root tip.

4. Typical canine of adult, demonstrating constriction of the foramen.

5. Canine of an elderly individual with a constricted pulp chamber and canal; this specimen has lost its original crown form because of wear during function.

How do I obtain my VTS in dentistry?

NAVTA created CVTS (Committee for Veterinary Technician Specialties) which governs Veterinary Technician specialists.

AVDT = Academy of Veterinary Dental Technicians

By December 15, all AVDT training program applicants and their mentors must together submit several required documents to the Credentials Chair of the Academy of Veterinary Dental Technicians along with the required fee:

Letter of Intent (Form 1)
The applicant’s curriculum vitae.
Complete employment history (Form 2)
Contract with veterinary dental mentor (Form 3)

All applicants and mentors are encouraged to review the current Credentials packet at the training program inception to become familiar with the scope of the final credentialing process.

After all credential guidelines are fulfilled, you may apply to take the exam, which is held once a year.

Dental explorers

Explores topography of tooth surface

Detects:

- Surface irregularities

- Completeness of debridement

- Smooth transitions of fillings

Scalers

Sharp tip and 3 sharp edges

Used for removal of supragingival calculus

Blade is straight or curved

Sickle scaler - most common

Curettes

Rounded tip and thin curved sides; rounded back

Removes calculus and debris from below the gumline (subgingival)

Gracey (1 cutting edge) and Universal (2 cutting edges) - most common

Calculus removal forceps

Quick removal of large pieces of calculus

Two tips:

- longer one over crown

- shorter one under calculus
