Quantitative estimation of haemodynamic changes of face by using termovision

METHODS: In Department of Oral Surgery 60 teeth in front part of jaws were extracted. Before the extraction 30 cases of patients were lightened by biostimulating laser. The other 30 patients had not any lightened by biostimulating laser. Thermovision camera was used to make en estimation of haemodynamic changes of facial skeleton after the surgery. All data were put together in a list including the age of patients, indications for extractions, power of laser, sex, use of curative diminishing congestion, part of jaw and size of operating area. Patients' feelings were assembled in a questionnaire.

Results: Distributions of temperatures recorded by thermovision camera in the operated areas are different. In cases, in which the biostimulating laser were used, temperature is higher than in cases with lack of biostimulating laser. This means that in cases where there was higher temperature operated areas had better blood supply. All of these caused better healing for the operated areas.

Conclusions: 1.The exploitation of biostimulating laser can be acknowledged as a helpful method in decrease of inflammations in dental surgery. 2. Termovision camera is very efficient in the assessment of changes of blood supply of tissues. 3. These methodology can be use as a additional method for cases with complication after surgery.
