Oral Exam and History • Patient history is very important for safety of the
patient. • Animal is put under elective anesthesia for dental
procedures. • Oral exam includes evaluation of the following:
• Face• Head• Neck• Occlusion• Intraoral structure
• Soft tissues• Teeth• Surrounding structures

Oral Exam/Periodontal Exam • Periodontium attachment structures of the teeth
includes:• Gingival connective tissue• Alveolar bone• Periodontal ligament• Cementum
• Examine for: • Mobility• Fracture/chips • Gingiva-Inflammation, hyperplasia, neoplasia • Sulcus depth(normal 0-3 mm)• Furcation exposure

Mobility Scoring • Stage 0: Physiological mobility 0.2mm.• Stage 1: Mobility is increased in any
direction 0.2-0.5mm.• Stage 2: Mobility is increased in any
direction 0.5 to 1 mm.• Stage 3: Mobility is increased in any
direction more than 1 mm.

Periodontal Disease • Gingivitis-inflammation of the gingiva.• Periodontitis-inflammation of all
structures of periodontum. • Four grades of periodontal disease.
• Review Chapter 6 of Holstrom: Veterinary Dentistry a Team Approach

Four Grades of Periodontal Disease

Periodontal Debridement • Done before scaling. • Manual removal of large plaque from
teeth.• Remove both hard and soft plaque both
supragingival and subgingival. • When debriding, make sure to use
cuffed ET tube and angle the patient’s head down so debris does is not aspirated.

Power Scaling: Energy → Vibration• When scaling, bacteria becomes aerosolized; be sure all
proper safety equipment is worn (face mask, goggles, gloves, gown).
• Power scaling instruments have a water cooled tip. • Allows for quick and effective cleaning.
• Sonic Scaler- powered by an air compressor on the dental unit, attached to a high speed air line.• Elliptical motion created by the air exiting the shaft.
• Ultrasonic Scaler-uses electrical energy that’s converted to sound waves creating rapid vibrations. Effectively removes biofilm and hard plaque.• Piezoelectric• Magnetostrictive
• Review chapter 3 of Holstrom

Ultrasonic Scaling
Ultrasonic scaling tip should never be at 90 degree angle toward tooth surface, the tip will cause damage to the enamel.

Hand Scalers • In general, consist of three parts:
• Handle• Shank• Working end
• Shank can be straight or bent. • Straight shank best for rostral teeth.• Bent better to reach more distal teeth.
• Types of scalers:• Sickle-Supragingival scaling• Curette-Subgingival scaling

Hand Scalers
Review Chapter 34 of McCurnin’s Clinical Textbook for Veterinary Technicians, 8th Edition.
Scaler parts include the Face, Cutting Edge and Tip
Curette parts include the Toe, Face and Cutting Edge.

Polishing • Smooths surface of teeth after scaling.• Abrasive agent is used as prophy paste. • Polisher cup (on the prophy angle) on low speed
hand piece either electrical or powered by air compressor.

Single-Root Extraction In the state of California, licensed veterinary technicians
are legally allowed to perform simple, or single-root extractions under the direct supervision of a licensed veterinarian.
Step 1: sever the gingival attachment using a dental elevator or a root tip pick.
Step 2: vertically rotate the elevator around the tooth increasing the space applying slow, steady pressure.
Step 3: continue applying pressure to break the periodontal ligament and exfoliate tooth.
