“…Infrared thermography detects infrared radiation and isothermal contour lines can be mapped on the surface of a body. For many years, IR thermography has been used successfully for measuring the temperature in materials, tissues, or organs 22, 23, 24. Although most heat from the light likely propagates into dental substrates, the dissipation of heat in the ambient air cannot be ruled out.…”

Positively charged quaternized poly(phthalazinone ether sulfone ketone) (QAPPESK) nanofiltration (NF) membranes were prepared from chloromethylated poly(phthalazinone ether sulfone ketone) by the dye/wet phase inversion method with N-methyl-2-pyrrolidone (NMP) and N,N-dimethylacetamide (DMAc) as solvents. The effects of the ratio of NMP to DMAc, the evaporation time, the evaporation temperature, and the coagulation temperature on membrane performance were evaluated by the orthogonal design method. The results showed that the optimal preparation conditions were an NMP/ DMAc ratio of 2/8, an evaporation time of 5 min at 70 C, and a coagulation temperature lower than 5 C. The effects of the additive type and concentration on the QAPPESK NF membrane cross-section morphology and performance were investigated in detail. Furthermore, QAPPESK NF membranes exhibited good thermal stability with stable membrane performance for 120 h at 60 C.

“…Temperature of the measuring area was changing clearly within the first 30 seconds and seemed to stabilize after 60 seconds. Basing on temperature histograms of the measuring area we obtained a graph, which we called the model of physiological oral mucosa temperature distribution [2]. In order to take above two different variants of measuring conditions onto consideration we created two models.…”

The aim of this study was to create the diagnosis method of early marginal gingiva pathological states and to evaluate treatment effects.In periodontal, chronic bacterial infection is observed, which caused inflammation. Initially there are a large amount of G (+) cocci, then they are replaced by Actinomyces viscosus, Actinomyces israelii, Fusobacterium, Veillonella, Bacteroides and Treponeme sp. The temperature changes are often one of the earliest symptoms of pathological process. Almost all pathological conditions, for example, inflammations or cancers (tumors) caused changes of hot stream, produced in sick tissue. This process can affect temperature of surrounding tissues and often it is demonstrated on the skin and oral mucosa surfaces. Thermographic methods allow determining the value and surfaces distribution of these temperature changes.

“…A group of researchers proposed a thermovision camera to visualize the heat change in tissue to indirectly trace the laser irradiation. [10][11][12] However, this is a less practical approach, because most of the LHR devices at the professional clinics have cooling tips built around the laser irradiation tip, which lessens the effect of thermovision camera.…”

Background and Objective: The robot-assisted automatic laser hair removal (LHR) system is developed to automatically detect any arbitrary shape of the desired LHR treatment area and to provide uniform laser irradiation to the designated skin area. Methods: For uniform delivery of laser energy, a unit of a commercial LHR device, a laser distance sensor, and a high-resolution webcam are attached at the six axis industrial robot's end-effector, which can be easily controlled using a graphical user interface (GUI). During the treatment, the system provides real-time treatment progress as well as the total number of ''pick and place'' automatically. Results: During the test, it was demonstrated that the arbitrary shapes were detected, and that the laser was delivered uniformly. The localization error test and the area-per-spot test produced satisfactory outcome averages of 1.04 mm error and 38.22 mm 2 /spot, respectively. Conclusions: Results showed that the system successfully demonstrated accuracy and effectiveness. The proposed system is expected to become a promising device in LHR treatment.
