State of the level of elecrical potentials of orthopedic patients with intolerances-syndrome

 

      The level of electric potentials of oral is significant prognostic criteria. This percentage increases with significant destructive, allergic processes, intolerance syndrome. Our studies have established this criterion increase in the experimental group after prosthesis removable of material “Ftorax”.

    Allergic and autoimmune processes recently is a significant proportion  of human diseases, including prosthetic dentistry. Among the materials commonly used in medicine and in the domestic sphere, widely used plastic. And with plastics that are used in medical practice, including in dentistry greatest popularity belong acrylic plastic and the methods of polymerisation .

       The nubmer of patients, which use dental prosthesis made of acrylic plastic  increases , that testified by increase of life expectancy  and wide development of pathology of hard tissues , and also peridont -  the main cause of teeth loss. The number of people , who used prostheses increased.At the same time increased the number of people, who can not use prostheses because of different causes. Clinically patients have expressive changes in oral cavity tissues, testifed  by allergic  and nonspecific inflammatory processes, burning and other.

     For estimation these reactions developed new structure of   acrylic plastmass increases  and methods of polymerisation .

     The term “intolerance” refers to unpleasant sensations in the mouth, forcing the patient to give up use the plastic prosthesis or use them briefly. Patients   complain of a print phenomenon paresthesia, pain and dryness in the lining of the prosthetic  bed, and its focal and diffuse inflammation.

     The term “intolerance” is term ,  which generalizes clinical symptoms, accompanied with prostheses effect.

      The modern level of our knowledge about this clinical phenomenon allows to make to express the idea, that the it has the appearance of hyperesthesia and allergy as contact stomatitis.

Materials and methods

    Comprehensive evalution  and treatment of patients in need of orthopedic treatment with the use of removable plate dentures , conducted at the Department of Prosthetic  Dentistry Medical Center CSMU.

      Were examined 45 patients(including women 23; men – 22), which were established partial dentures of material “Ftorax”.These patients were treatment group(aged 45-75 years). The composition of the control group consisted of 40 patients between the ages of 25-65 years.

      Comprehensive survey of patients was performed according to the scheme were from the collection pf medical history, oral examination, peridontal examination and alveolar bone in the area of missing teeth, clinical and labarotory examination, diagnosis.

Results of investigation

 Analysis of the electric potentials f the oral cavity in the control group showed that the electrophysiological indices were 156,0 ± 3,7 mV, after the installation of removable plate dentures made of acrylic plastic in the group of patients who developed syndrome of intolerance, it increased by 15,4 % (P<0,05) and amounted to 180,0±4,0 mV. These data support the development of an allergic process that requires corrrection.

 Conclusion

1.      Noticed, that in many cases  after the installation of removable plate dentures made of acrylic plastic developed syndrome of intolerance, that accompanying by inflammatory processes in peridontal tissues.

2.      The analysis of indexes of  elecrical potentials of oral cavity  in orthopedic patients with syndrome of intolerance has showed , that after  removable plate dentures installation , made from the materials”Ftorax” the level of elerical potentials pf the oral cavity increases sharply.
