General Rotary Instrument Usage Tips

  • For the safety of both user and patient, only qualified dentists should work with dental burs.
  • Sterilize all burs before each use.
  • Burs should be replaced frequently to avoid using a dull, worn, or damaged bur on a patient. A dull or damaged bur could result in reduced efficiency and possible harm to the patient.
  • Never force a bur into the turbine.
  • Observe recommended speeds and air pressure. This is particularly true for burs with a large head size or coarse/super coarse diamond grit size because too much speed could create undesirable heat.

 

  • Do not put pressure on the bur when in use.
  • Don’t keep the bur still; constant movement will avoid burning of the bur.
  • Do not “extend” the bur (always insert the bur fully into the handpiece chuck).
  • Always use the bur with sufficient water coolant.
  • Do not use a bur in a worn chuck; doing so might cause bur slippage and/or vibration that can lead to breakage.

Rotary Instrument Maintenance

Cleaning

  • Always wear gloves when handling contaminated instruments.
  • Presoak the burs for at least 10 minutes in a disinfection solution designed for dental burs that contains a corrosion inhibitor to minimize the dulling of diamond coating.
  • Use a brush to clean the burs thoroughly if needed.
  • Rinse several times to remove the disinfection solution.
  • Dry the burs and store in a clean and moisture-free environment.

Cleaning with Ultrasonic

  • Burs may be ultrasonically cleaned by inserting them in bur holders.
  • A cycle of 5 minutes is recommended, using a general purpose cleaner.
  • Rinse several times after cleaning.
  • Dry the burs and store in a clean and moisture-free environment.

Sterilization

  • Proper sterilization of instruments is extremely important to eliminate the possibility of cross infection of patients and staff with communicable diseases.
  • Place the burs in sterilization bags.
  • Autoclave the burs for atleast10 minutes at a temperature of 135 C.
  • Dry the burs and store in a clean and moisture-free environment.
  • Use a dry heat sterilizer at 170 C (340 F) for 1hour.When used according to the manufacturer’s instructions, this will not corrode or dull carbide burs.
  • Avoid cold sterilizing solutions as they contain oxidizing agents which may weaken carbide burs.

Note: It is the responsibility of the user to ensure that sterilization is effective.
