“…This was previously demonstrated in a pilot study reporting a temperature increase 3 days and 5 days post-operatively compared with the baseline temperature. 4 However, the present study showed decreased temperature of the control side and no change of the operated side compared with the pre-operative examination. The background of this apparent discrepancy is unknown, but may be related to variations in skin temperature over time.…”

“…It is easy to use, non-invasive and relatively inexpensive to acquire and maintain. As inflamed tissue is characterised by liberation of heat, thermography has been used to detect inflammation after the surgical removal of mandibular third molars 4,19 and to detect nerve injuries. 10,13,14 Moreover, a higher skin temperature on the affected side has been shown in a patient with Frey's syndrome.…”

“…The method has been used for multiple purposes within medicine [1][2][3] and in the field of dentistry. [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19] An inflammatory process is characterized by heat production and emission as one of the cardinal symptoms, which is why thermography may be used to evaluate inflammation. Many studies have been performed on the use of thermography in the diagnosis of temporomandibular joint disorders 5,6,9,11,12,15,16 and diagnosis of nerve injuries after surgery or trauma, 10,13,14,17 as well as within clinical research.…”

Objective: To assess differences in skin temperature between the operated and control side of the face after mandibular third molar surgery using thermography. Methods: 127 patients had 1 mandibular third molar removed. Before the surgery, standardized thermograms were taken of both sides of the patient's face using a Flir ThermaCam TM E320 (Precisions Teknik AB, Halmstad, Sweden). The imaging procedure was repeated 2 days and 7 days after surgery. A region of interest including the third molar region was marked on each image. The mean temperature within each region of interest was calculated. The difference between sides and over time were assessed using paired t-tests. Results: No significant difference was found between the operated side and the control side either before or 7 days after surgery (p . 0.3). The temperature of the operated side (mean: 32.39 u C, range: 28.9-35.3 u C) was higher than that of the control side (mean: 32.06 u C, range: 28.5-35.0 u C) 2 days after surgery [0.33 u C, 95% confidence interval (CI): 0.22-0.44 u C, p , 0.001]. No significant difference was found between the pre-operative and the 7-day postoperative temperature (p . 0.1). After 2 days, the operated side was not significantly different from the temperature pre-operatively (p 5 0.12), whereas the control side had a lower temperature (0.57 u C, 95% CI: 0.29-0.86 u C, p , 0.001). Conclusions: Thermography seems useful for quantitative assessment of inflammation between the intervention side and the control side after surgical removal of mandibular third molars. However, thermography cannot be used to assess absolute temperature changes due to normal variations in skin temperature over time.

There was no significant difference in gingival or incisal temperatures between pairs of contralateral maxillary lateral incisors and a consistent temperature gradient existed from gingival to incisal areas of healthy maxillary lateral incisor teeth. The protocol described is suitable for TI of vital teeth. However, TI measured tooth surface temperature only which was extremely sensitive to air currents. A 15-min acclimatization period under rubber dam was adequate to allow stable tooth surface temperature measurement.

“…Based on the above studies it can be concluded that, IRT can be successfully used for temperature monitoring of the dental tissue and optimization of sterilization process. Other applications of infrared thermography in dental sciences include evaluation of craniomandibular disorders [157], detection of carotid occlusal disease [158], quantification of the effects of post-surgical inflammation [159,160].…”

The primary objective of this study is the development of transparent thin film materials in the IR enabling strong infrared absorption of organic compounds in the vicinity of metal nanoparticles by the surface plasmon effect. For developing these optical micro-sensors, heterostructures combining gold nanoparticles and chalcogenide planar waveguides are fabricated and adequately characterized. Single As 2 S 3 and Ge 25 Sb 10 Se 65 amorphous chalcogenide thin films are prepared by radiofrequency magnetron sputtering. For the fabrication of gold nanoparticles on a chalcogenide planar waveguide, direct current sputtering is employed. Fabricated single layers or hetero-structures are characterized using various techniques to investigate the influence of deposition parameters. The nanoparticles of gold are functionalized by a self-assembled monolayer of 4-nitrothiophenol. Finally, the surface enhanced infrared absorption spectra of 4-nitrothiophenol self-assembled on fabricated Au/Ge-Sb-Se thin films hetero-structures are measured and analyzed. This optical component presents a ~24 enhancement factor for the detection of NO 2 symmetric stretching vibration band of 4-nitrothiophenol at 1336 cm −1 .
