SUBSTANCE: clinical dental health parameters following the endodontic treatment (Cl parameter) expressed in the quantitative equivalent according to table 3, are recorded. The X-ray periapical tissue health parameters following the endodontic treatment (Rtissue parameter) expressed in the quantitative equivalent according to table 4, are recorded.The X-ray root filling health parameters following the endodontic treatment (Rfilling parameter) expressed in the quantitative equivalent according to table 5, are recorded. In questionable cases, the recording procedure involves a higher rate of the estimation scale, and for multirooted teeth - the highest rate specified; each following root filling health parameter and its assessment criterion is secondary from the previous one depending on a degree of risk of potential post-endodontic complications and arranged in the ascending order, thereby characterising an increase of a therapeutic defect rate, except for the first assessment criteria of each of the parameters of a quantitative aspect of the X-ray filling health with 1 point assigned to describe the ideal clinical outcome for the given parameter. A complex index of the endodontic treatment expressed in points is calculated by formula: CIET = Cl+Rtissue+ΣRfilling, wherein CIET is the complex index of the endodontic treatment; Cl is the quantitative characteristics of the clinical dental health following the endodontic treatment; Rtissue is the quantitative characteristics of the X-ray periapical tissue health following the endodontic treatment; ΣRfilling is a total score derived in accordance with the criteria of the quantitative characteristics of the X-ray root filling health following the endodontic treatment. The clinical outcome is analysed on a basis of theoretical evaluation of numerical ranges of accepted values of the complex index of the endodontic treatment enabling to specify the therapeutic approach to the patient. The complex index less than 12 points testifies to adequate leak resistance of the root filling; pathological changes in the periapical tissues are absent; the tooth does not need to be treated; the prediction is considered to be favourable. If the range is 13-19 points, the root filling occurs to seal the root canal inadequately; the risk of periapical complications is minimised; the 6-24-month case follow-up is recommended. The range of 20-37 points shows the unsatisfactory leak resistance of the root filling; the high probability of post-endodontic complications is stated; the recurrent endodontic manipulation is recommended; the prediction is open to question. If the index reaches 37 points and more, the surgical management is recommended.

EFFECT: by additional quantitative characteristics of the clinical and X-ray periapical tissue and root filling health, the method enables characterising the quality of the therapeutic outcomes in the nearest and remote period, and specifying the indications for a certain method of treating.

SUBSTANCE: invention refers to medicine, functional diagnostics and can be used for preclinical, predoctoral examination, assessment of the functional state of body organs and systems, and pre-diagnosis. The method involves measuring electrical conductivity (EC) of 24 representing points of 12 symmetrical meridians, determining an arithmetic mean (AM) value of these measurements and specifying a corridor of permissible values for this patient, to which the derived values are compared in order to assess the functional state of the patient's body. That involves using the following criteria: a ratio of total ECs of Yin meridian points to total ECs of Yang meridian points, a ratio of total ECs of arm points to total ECs of leg points, a ratio of total ECs of left-side points to total ECs of right-side points. ECs are measured at voltages 5V, and/or 9V, and/or 12V. If the measurements are taken at 9V, the measured ECs are re-calculated by formula: I new=9/(29/I measured-0.1)*Coeff, (I); if the measurement process is performed at 12V, the measured values are re-calculated by formula: I new=9/(29/I measured-0.1)*Coeff, (I); and at 5V: I new=1 measured*Coeff, (III), wherein in (I), (II) and (III) respectively: I new is the re-calculated EC; I measured is the measured EC; Coeff is a correction coefficient taking into account a meridian conductivity heterogeneity. The re-calculated values are transformed into adjusted ones by formula: I adjusted=I new/I mean, wherein: I adjusted is the adjusted EC; I new is the non-adjusted re-calculated EC; I mean is the arithmetic mean value of all the 24 measurements. That is followed by delimiting an individual normal corridor for this patient depending on the preset diagnostic sensitivity S and a width of corridor of the permissible EC values Wpv. The Wpv represents a range of EC values measured in this patient, whereas the diagnostic sensitivity S is specified depending on selecting the patients with a certain disease. Delimiting the individual normal corridor for this patient is ensured by measuring intermediate coefficients for lower Kl and upper Ku corridor limits respectively: Kl=1-(1-S)*Wpv/2.1 and Ku=1+(1-Kl)*1.1. Lower L and upper U limits of the individual normal corridor are determined: L=Kl* I mean and U=Ku* I mean. That is followed by comparing I adjusted to the derived limits of the individual normal corridor.

EFFECT: method provides high accuracy of the individual diagnosis.

SUBSTANCE: "orthopaedic index" is calculated as a sum of three values. The first value is derived by conducting densitometry, and points are assigned according to its findings: 1 point for norm, 2 points for osteopenia, 3 points for osteoporosis, and 4 points for severe osteoporosis. The second value is derived by means of Charlson comorbidity index; 0-2 points according to the Charlson comorbidity index scale correspond to 1 point of the second value; 3 points of the Charlson comorbidity index scale are 2 points of the second value; 4 points of the Charlson comorbidity index scale show 3 points of the second value, while 5 points and more of the Charlson comorbidity index scale correspond to 4 points of the second value. The third value is determined by assessing the quality of life as per the scales SF-36; 0-200 points according to the scales SF-36 correspond to 4 points of the third value; 201-400 points of the scale SF-36 show 3 points of the third value; 401-600 points of the scales SF-36 provide 2 points of the third value, and 601-800 points correspond to 1 point of the third value. Total score is deriving by summing up the three values to determine "the orthopaedic index": I - 1-3 points, II - 4-6 points, III - 7-9 points, IV - 10-12 points. The form of treatment is defined: the patients with index I have the endoprosthesis replacement with endoprostheses with a shortened leg of the femoral component, the greater diameter of the head (36 mm or more); the patients with index II have the endoprosthesis replacement with cementless anchored total endoprostheses; the patients with index III have the total hip replacement with cemented endoprostheses; the patients with index IV have the endoprosthesis replacement with cemented anchored bipolar endoprostheses.

EFFECT: through assessing the available factors influencing the postoperative period, prosthesis anchoring in its bed, potential endoprosthesis rejection, functional effect and potential aggravation of comorbidities, the method can improve functional outcomes, reduce the risk of endoprosthesis loosening and the risk of recurrent operations.

SUBSTANCE: device comprises a cleaning head with conductive fibre bristles which are used to feed a potential for the electrochemical activation of the dental bleaching agent, e.g. peroxide nearby the teeth. A complex impedance device system (62) or an optical device system (27) provides the information whether the bristles with the conductive fibres are nearby the dental surface or nearby the gingival surface. The first of the above systems - the complex impedance one - uses an electrical signal through a fibre to determine the complete impedance of a chain comprising a tooth or a gingival surface with the complex impedance supposed to vary in accordance with the fact if the tooth or the gingival surface is involved into the chain. The optical system generates a light beam, which is directed to the oral cavity surface through the conductive fibre with the return light colour showing if the surface is dental or gingival. If it is the tooth that is detected, the dental bleaching agent is activated on the bristle, whereas determining the gingival tissue keeps the dental bleaching agent inactive on the bristle.
