Dental Instruments And Their Uses

During my first visit to a dental clinic, I tend to notice that there are many different dental kits or dental instruments that are laid down beside the dental chair. A dentist and dental nurse use a variety of dental instruments/equipment for examining, cleaning, cutting and restoring teeth.

Dental Instruments are dental tools dental team use such as (Dentists, Dental nurses), to be able to remove teeth, Identify and select for all dental treatments.

According to Coventry Dentists, there are many different dental instruments used by oral health care professionals in their different roles and specialities. When I got my fillings done by a Dentist in Sacramento they introduced me to the different tools they used.

Certain types of instruments are unique to various therapeutic procedures. During an examination by a general dentist, the  most commonly used instruments are the cotton pliers, mouth mirror, probes and explorers.” deded

Practical Identification of Dental instruments

Today, the dental team (such as a dental nurse) have major challenges in identifying dental instruments and selecting them for dental use.
  Here is a practical guide in identifying (dental instruments and dental materials) and selecting for dental use to help our career and boost our morale. Not everyone is familiar with these dental tools names and information. Before I list all the basic dental instruments pictures and names available in a dental office/clinic and their uses.
Dental Instruments Uses

What is instrumentation?

Instrumentation is the familiarization of the dental team such as (Dentists, Dental Nurse, Dental technologists), with the instrument to be able to classify, Identify and select for dental use.

Types of instruments?

  1. Working end: This is a part that is used to carry out the purpose and the function of an instrument.
  2. The shank: It is the part of an instrument that connects the working end and the handle.it may be a curve or straight.
  3. And handle: The handle is the part that we hold. For example, Double-ended instrument I.e two working ends for example spoon excavator and carver. The single-ended instrument, for example, Coupland elevator.  Corn socket instrument I.e they are separated from the shank instrument and working end and permit instrument exchange or replacement for example mouth mirror, handpieces and bur. 
Practical Identification Of Dental Instruments

Physical identification of dental instruments include:

  1. Basic instruments
  2. Basic Materials used in dentistry
  3. Local anaesthesia
  4. Instruments and materials used in rubber dam placement
  5. Instruments and materials used in moisture control
  6. Handpieces, Burs the rotary attachment
  7. Matrix band and matrix retainers
  8. Elevators
  9. Extraction forceps
  10. Impression trays
  11. Orthodontics instruments.

Dental instruments can be either hand-held or rotary (for example-driven in a handpiece) and some can be of fiber optic light sources and ultrasonic equipment.

Cavity Preparation Dental hand instruments

The types of hand instruments can be categorized based on their function:

  • Examining the mouth and teeth
  • Scaling or professional cleaning of teeth
  • Cutting teeth and removing cavities
  • Placing and condensing filling materials
  • Carving and finishing dental fillings
  • Miscellaneous types.

General features of hand instrument design

Most of the hand-held instruments are made of stainless steel or sometimes carbon steel. Chisels and scalers often have tungsten carbide tips. The basic design of a hand instrument has a blade, a shank, and a handle.

Cavity Preparation Hand-Cutting Instruments

  • Enamel Hatchet, Binangel Chisel, Wedelstaedt Chisel, Hoe Excavator:  To remove decay and refine cavity preparation. TRAY SET-UP: Amalgam, composite.
  • Straight Chisel: To remove decay and refine cavity preparation; pushing motion
  • Angle Former: To remove decay and refine cavity preparation, especially line angles and point angles; pushing motion
  • Gingival Margin Trimmer: To remove decay and refine cavity preparation, especially to bevel the gingival margin of the cavity preparation

Basic instruments

 The examination set is the basic instrument used first to examine a patient. This include:
  1.  Dental probe: it is used to detect the depth of caries.
  2.  Mouth mirror: it is used to view the patient mouth or for visualization of the patient mouth.
  3.  College tweezers: For picking cotton wool into the patient mouth or for picking up some instrument.

Basic Materials needed in Dentistry

  1.   Gloves: For protection
  2.  Face mask: For protecting the face.
  3.  Cotton wool: For cleaning up the saliva, blood and to stop bleeding.

    Local Anesthesia

  • Topical Local Anesthesia For example. Ethyl chloride
  • Injectible Local Anesthesia For example. Xylocaine

Uses of Topical Anaesthetics

    1. Prevention of pain from needles during injections.
    2. Relief of painful sockets, ulcers, and wounds
    3. Prevention of gingival discomfort while taking copper ring impression.

Instruments used for placing and condensing filling materials

Instruments Used For Placing And Condensing Filling Materials

  • Plastic instruments are used to convey and shape filling materials and are usually flat blades that do not use heavy pressure. Some instruments have rounded ends for shaping and burnishing the surfaces of fillings. Plastic instruments are usually made of stainless steel for most materials though there are also thin Teflon-coated or titanium nitride instruments that are non-stick for composite fillings.
  • Condensers or pluggers instruments are used for compressing and forming filling materials. You must apply heavy pressure in order to use these instruments properly. So, therefore, these instruments are usually used for metal or amalgam fillings.
