Summary

Dental injuries during endotracheal intubation are common, particularly to upper teeth. A new protective device was developed and tested, showing promise in reducing dental trauma during intubation procedures.

Area of Science:

  • Dental Trauma
  • Anesthesiology
  • Medical Device Design

Context:

  • Dental injuries are a known complication of endotracheal intubation.
  • A 10-year analysis revealed a 1 in 4,000 rate of dental injuries during intubation.
  • Upper jaw teeth, especially incisors, are most frequently affected.

Purpose:

  • To analyze the incidence and nature of dental injuries during endotracheal intubation.
  • To assess anesthesiologists' awareness of dental risks and need for protective measures.
  • To design and evaluate a novel dental protective device for intubation.

Summary:

  • A study of 126 intubation-related dental injury cases found fractures and dislocations common.
  • Anesthesiologists reported high awareness of dental risks but a lack of protective measures.

  • A newly designed gutter-shaped dental guard was tested in 108 patients.

    • Impact:

    • The protective device was effective in 73.2% of patients, reducing intubation difficulty.
    • Mouth opening was minimally reduced (mean 4.2 mm) with the device.
    • The device may be less suitable for patients with limited mouth opening (<3.5 cm).
