“…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 .

“…Computed tomography (12,14) and thermography (15) can also be used to study carotid calcifications. In this case, an anteroposterior projection with the patient's mouth shut was taken to confirm that the radiopaque nodular masses were located in the intervertebral space between C3 and C4.…”

“…Contrast angiography is also used for the confirmation of the presence of calcifications, its nature and extension (1,12). However, the high cost, the potential for serious complications, and the limited information obtained by this method has stimulated the development of other techniques which are not invasive, such as color flow Doppler studies (ultra-sound) and Doppler spectral analysis (Spectral Doppler Scanner) (1,5,12). These techniques are relatively inexpensive and have a low risk of complications and low mortality rates, while supplying sophisticated images.…”

Most cerebrovascular accidents (CVAs), commonly referred to as noncardiogenic strokes, occur as a result of atherosclerosis involving the common, internal and external carotids arteries, due to atheroma formation.Several factors influence atheroma formation, such as hypertension, smoking, diabetes mellitus, hypercholesterolemia, obesity and sedentary lifestyle among others. When atheromas are positioned inside the vessel lumen, they alter the flow of blood, causing the stroke. These atheromas, that are calcified plaques, can be observed in panoramic radiography. (J. Oral Sci. 45, 177-180, 2003) Key words: panoramic radiography; cerebrovascular accident; stroke, atheroma.Case Report A 68-year-old man came to the Radiology Clinic of the Piracicaba Dentistry School at the State University of Campinas for panoramic radiography screening prior to prosthetic treatment. Panoramic radiography showed several bilateral nodular radiopaque masses located inferior and posterior to the angle of the jaw, above the hyoid bone (Fig. 1). As the vertebral bodies were not visible, a further anteroposterior projection with the patient's mouth shut was taken, for the purpose of differential diagnosis. This radiograph verified that these masses were located in the intervertebral space between C3 and C4 (Fig. 2).Physical examination revealed no neck bruits and the patient reported no history of overt transient ischemic Correspondence to Dr. Flavio Ricardo Manzi,

“…Previous studies reported a 2-11% prevalence rate of CACs on panoramic radiographs in the dental patient population 1,12,17,20,21,22. Several studies showed that the detection of CACs on panoramic radiographs might be a useful aid in detecting patients at the risk of stroke 2,12,21,23.…”

“…Several studies showed that the detection of CACs on panoramic radiographs might be a useful aid in detecting patients at the risk of stroke 2,12,21,23. The patients' medical histories with panoramic radiographic evidence of CAC revealed risk factors of stroke, male gender, advanced age, smoking, hypertension, diabetes, and hypercholesterolaemia 2,12,17,20,21. In a previous study, patients who were found to have CAC on panoramic radiographs had a high frequency of end points in a relatively short period of time after the identification of CAC 24.…”

Interobserver agreement on the diagnosis of carotid artery calcifications on panoramic radiographs

PurposeThis study was performed to investigate the interobserver agreement on the detection of carotid artery calcifications on panoramic radiographs.Materials and MethodsThis study consisted of panoramic radiographs acquired from 634 male patients of the age of 50 years or older. Having excluded carotids of no diagnostic quality, 1008 carotids from the panoramic radiographs of the patients were interpreted by two oral and maxillofacial radiologists independently for the presence of carotid artery calcifications. Statistical analysis was used to calculate the interobserver agreement.ResultsInterobserver agreement was obtained for 932 carotids (92.4%). Inconsistent interpretation of 76 carotids (7.5%) between the two observers was found. Cohen's kappa value was 0.688 (p<0.001).ConclusionThe probability of a match between the two observers was substantially high.
