METHOD FOR PREDICTION OF DEVELOPMENT AND EARLY DETECTION OF INITIAL OCCUPATIONAL FLUOROSIS Russian patent published in 2014 - IPC A61B6/00 A61B10/00 

FIELD: medicine.

SUBSTANCE: occupational history is studied; clinical and radiological examinations, as well as an osteodensimetry are carried out to detect the following values: profession; osteoporosis sings in at least one of elbow or knee joints; a hyperostosis coefficient of a middle diaphysis of the left radial bone; a reference density of a distal metaphysis of the right radial bone; a hyperostosis coefficient of a middle diaphysis of the left shin bone; a reference density of a proximal metadiaphysis of the right shin bone; a T criterion in the right radial bone; a T criterion in the lumbar spine. That is followed by calculating prognostic coefficients F₁, F₂, F₃ to be compared. If F₁ is more than F₂ and F_3, occupational fluorosis is suspected. If F₂ is more than F₁ and F₃, a high risk of developing fluorosis is predicted. If F₃ is more than F₁ and F₂, a risk of developing fluorosis is considered to be low.

EFFECT: method enables more accurate prediction of developing fluorosis in workers by assessing a combination of risk factors, clinical-radiological and osteodensimetric signs of bone remodelling which are the most informative ones.
