Mouth mirror, a commonly used dental instrument

Dental instruments are the tools that dental professionals use to provide dental treatment. They include tools to examine, manipulate, restore and remove teeth and surrounding oral structures.

Standard instruments are the instruments used to examine, restore and extract teeth and manipulate tissues.

Examination instruments[edit]

These tools allow the dental professional to manipulate tissues for better visual access during treatment or during dental examination.

Mirror[edit]

Dental mirrors are used by the dentist or dental auxiliary to view a mirror image of the teeth in locations of the mouth where visibility is difficult or impossible. They also are used for reflecting light onto desired surfaces, indirect vision, and with retraction of soft tissues to improve access or vision.

Local anesthesia[edit]

About Anesthesia Anesthesia is broken down into three main categories: local, regional, and general, all of which affect the nervous system in some way and can be administered using various methods and different medications.

Here's a basic look at each kind:

Local anesthesia. An anesthetic drug (which can be given as a shot, spray, or ointment) numbs only a small, specific area of the body (for example, a foot, hand, or patch of skin). With local anesthesia, a person is awake or sedated, depending on what is needed. Local anesthesia lasts for a short period of time and is often used for minor outpatient procedures (when patients come in for surgery and can go home that same day). For someone having outpatient surgery in a clinic or doctor's office (such as the dentist or dermatologist), this is probably the type of anesthetic used. The medicine used can numb the area during the procedure and for a short time afterwards to help control post-surgery discomfort.

Dental drills[edit]

A high-speed dental handpiece.

Dental handpieces come in many varying types which include: High speed air driven (also known as an airotor), slow speed, friction grip, surgical hand piece. Straight handpiece with a sharp bur.

Burs[edit]

Dental Burs cutting surface are either made of a multifluted tungsten carbide, a diamond coated tip or a stainless steel multi fluted rosehead. There are many different types and classifications of burs some of the most common are: the round bur (sizes ¼ to 10) or inverted cone (sizes 33½ to 90L). Burs are also classified by the type of shank. For instance a latch type, or right angle bur is only used in the slow speed handpiece with contra-angle attachment. Long shank or shaft is only used in the slow speed when the contra-angle is not in use, and finally a friction grip bur which is a small bur used only in the high-speed handpiece.

There are many bur shapes that are utilized in various specific procedures.

Operative burs[edit]

Flat fissure, pear-shaped, football, round, tapered, flame, chamfer, bevel, end cut, bud bur, steel, inverted cone, diamond, brown stone, and greenstone.
