Summary
Thermography effectively diagnoses periapical inflammatory lesions, with higher temperatures indicating acute periapical abscess (AA). This non-contact imaging method aids in early detection of inflammatory reactions.
Area of Science:
- Dentistry
- Medical Imaging
- Diagnostic Technology
Background:
- Thermography utilizes non-contact devices to capture and analyze thermal data.
- Periapical inflammatory lesions require accurate diagnostic methods for effective treatment.
- Assessing thermography's validity against reference standards is crucial for its clinical adoption.
Purpose of the Study:
- To validate thermography as a diagnostic tool for periapical inflammatory lesions.
- To determine temperature ranges for specific conditions: acute pulpitis with apical periodontitis (AAP), acute periapical abscess (AA), and chronic periapical abscess (CA).
Main Methods:
- 80 patients diagnosed using clinical and radiographic criteria.
- Infrared thermography (FLIR E-5) with extraoral and intraoral imaging.
- Statistical analysis of temperature data and diagnostic agreement (Kappa coefficient).
Main Results:
- Significant differences in mean intraoral temperatures observed across AA, CA, and AAP groups (P < 0.001).
- Highest mean intraoral temperature recorded for acute periapical abscess (AA).
- Significant agreement found between thermographic evaluation and combined clinical/radiographic assessments (P < 0.001).
Conclusions:
- Thermography is a valid, quantitative, and non-ionizing method for diagnosing periapical inflammatory lesions.
- Elevated temperatures correlate with acute periapical abscess, suggesting diagnostic potential.
- Thermography may facilitate early detection of inflammatory processes, aiding preclinical diagnosis.

Body temperature can be assessed using various devices and measured in Celsius or Fahrenheit.
Glass-bulb Thermometer:
Glass-bulb thermometers are hollow glass tubes with a bulb tip containing liquid such as ethanol or mercury. Historically, glass bulb mercury thermometers were the standard device to measure body temperature. Today, mercury thermometers are prohibited in many countries due to the hazardous effects of mercury and the risk of exposure if the glass bulb breaks. In general,...

2.5K
A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.

01:43Thermosensation
32.8K
Peripheral thermosensation is the perception of external temperature. A change in temperature (on the surface of the skin and other tissues) is detected by a family of temperature-sensitive ion channels called Transient Receptor Potential, or TRP, receptors. These receptors are located on free nerve endings. Those detecting cold temperatures are closer to the surface of the skin than the nerve endings detecting warmth. These thermoTRP channels, while temperature selective, have relatively...
