Today’s goals

What will you learn?

Open the roomAir, water, suction, and power.
Know the chairControls, light, tray, and cuspidor.
Know the toolsHigh-speed, low-speed, syringe, and suction.
Use daily X-raysXCP, bitewings, PAs, and pre/post-op images.
01 β€’ The operatory

Start with the room

Before the first patient, make sure the room is clean, stocked, and ready.

Basic examination instruments from your manual (page 49).
Dental equipment from the Smile Center manual
Dental X-ray equipment (manual, page 52). Ask your instructor to show the compressor in your office.

  • Air powers many handpieces.
  • Water rinses and cools.
  • Suction removes saliva, water, and debris.
  • Power turns the unit on.
Easy memory trick: Air = power. Water = rinse. Suction = remove.
🩻 Daily X-ray tip

At the start of the day, make sure your X-ray area is ready. Check that the sensor or plates, barriers, and holders are available and clean according to office protocol.

02 β€’ Chair station

Know the dental chair

Basic dental instruments from manual
Basic exam instruments. Your instructor will demonstrate chair controls using the actual chair.

Main parts to know

  • Chair controls β€” move the patient up, down, back, and upright.
  • Overhead light β€” helps the dentist see clearly.
  • Instrument tray β€” holds instruments during treatment.
  • Cuspidor β€” spit bowl, if the chair has one.
  • Main power switch β€” turns the unit on and off.
  • Foot pedal β€” activates the handpiece.

Class practice: Find each part on the real chair.

🩻 Daily X-ray use

When taking an intraoral image, help position the patient comfortably. Good patient position makes the image easier to take.

03 β€’ Handpieces

Learn the main handpieces

High speed dental handpiece

High-speed handpiece

Used to cut tooth structure and remove old fillings.

Bur used: friction-grip bur.

Low speed dental handpiece

Low-speed handpiece

Used for polishing, finishing, and some caries removal.

Bur used: latch-type bur.

Important: The bur must match the handpiece. Always check that the bur is fully seated and locked before use.
🩻 Daily X-ray use

Before some procedures, the dentist may order an X-ray to check the tooth. After treatment, another image may be needed to check the result.

04 β€’ Tray setup and basic tools

Set up a clean tray

Dental tools arranged on a workstation
Clean, organized setup helps the whole team work faster.

Basic exam tray

  • Mouth mirror
  • Explorer
  • Periodontal probe
  • 2x2 gauze
  • Cotton rolls
  • Patient bib and bib clip
  • Saliva ejector or HVE as needed

Every office is a little different. Follow your instructor and office setup.

Cotton rolls
Gauze
2x2 gauze
🩻 Daily X-ray use

Add X-ray supplies when needed: sensor or plate, barrier, XCP holder, and the correct exposure requested by the dentist.

05 β€’ Suction and syringe

Keep the mouth clean and dry

Dental suction tips

Suction tips

HVE is strong suction.

Saliva ejector is gentle suction.

Surgical suction is narrow and precise.

Air-water syringe

The air-water syringe has two buttons.

  • Air button β€” dries the tooth.
  • Water button β€” rinses the tooth.
  • Both buttons β€” makes spray.

Learn how your chair is set up. Some chairs look different.

Simple rule: Strong suction for drilling. Gentle suction for resting water and saliva.
🩻 Daily X-ray use

Drying the teeth and controlling saliva can help before some images, especially when placing a sensor or positioning device.

06 β€’ X-rays in daily use

Use X-rays every day

This module does not teach radiation law. It teaches the everyday dental-assisting side of X-rays.

  • Bitewings are common for checking the crowns of back teeth and bone level between them.
  • Periapicals (PAs) show the whole tooth and root area.
  • Pre-op images may be needed before root canals, extractions, crowns, or other treatment.
  • Post-op images may be needed to check the final result.
07 β€’ Real X-ray examples

See what common images look like

Bitewing x ray example 1

Bitewing example 1

Shows upper and lower back teeth together.

Bitewing x ray example 2

Bitewing example 2

Another bitewing example. Good for class discussion.

Periapical x ray example

Periapical (PA) example

Shows the full tooth, root, and bone around it.

Panoramic x ray example

Panoramic example

Shows a wide view of the teeth and jaws.

Pre and post treatment X-rays
Pre-operative and post-operative dental radiographs (manual, page 63).
Completed root canal radiograph
Completed root canal example (manual, page 68).
Class discussion idea: Ask the class: β€œWhich image would you want for a full-mouth overview? Which one would you want to check one tooth?”
08 β€’ Anesthetic syringe

Know the syringe parts

Dental syringe handling
Students should learn the parts and safe handling first.

Parts to name

  • Barrel β€” holds the anesthetic carpule.
  • Thumb ring β€” where the thumb goes.
  • Plunger / harpoon β€” engages the carpule.
  • Needle β€” attaches to the syringe.

Practice only with instructor supervision. Use safe training steps. Handle sharps very carefully.

🩻 Daily X-ray use

Before an extraction or endodontic procedure, the dentist may review a PA or panoramic image to plan treatment.
