Assessing Body Temperature - Oral01:14

Assessing Body Temperature - Oral

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:
Instruct the patient to open their mouth and place...

Summary

The type of curing light and its distance from the tooth significantly impact temperature during orthodontic bonding. Light-emitting diode (LED) curing close to the tooth surface generates the most heat.

Area of Science:

  • Dental Materials Science
  • Orthodontic Technology
  • Biomedical Engineering

Background:

  • Orthodontic bracket bonding involves light-curing adhesives, which can generate heat.
  • Understanding temperature changes is crucial for patient comfort and pulp vitality.
  • Optimizing curing parameters can enhance bonding efficacy and safety.

Purpose of the Study:

  • To investigate the influence of different curing units (LED and Halogen) and light-tip distances on temperature rise during orthodontic bonding.
  • To quantify temperature increases using infrared thermography and artificial neural networks.
  • To identify optimal curing conditions minimizing thermal effects.

Main Methods:

  • Extracted human premolar teeth were used for bracket bonding.
  • Curing was performed using Light-Emitting Diode (LED) and High Intensity Halogen (HQTH) units.
  • Temperature was recorded using an infrared camera and analyzed with artificial neural networks at two distances (0 mm and 10 mm).

Main Results:

  • Both curing unit type and distance significantly affected temperature increase (p < 0.001).
  • LED curing at the tooth surface resulted in the highest temperature increase (11.35°C ± 0.91°C).
  • HQTH curing at 10 mm distance yielded the lowest temperature increase (2.57°C ± 0.6°C).

Conclusions:

  • LED curing units generate significantly higher temperatures than HQTH units.
  • Shorter light-tip to tooth surface distances increase temperature rise.
  • Longer exposure times correlate with increased temperature during orthodontic bonding.
