Abstract

Pathological changes in the mouth that lead to the development of dental diseases occur in violation of the normal microflora of the mouth, which provides anticolonization resistance, prevents colonization of the body from other microorganisms. Reduced colonization resistance leads to an increase in the number and range expansion of pathogenic bacteria, increasing the risk of infection.

State of dysbiosis is characterized by a change in the composition of microbiota, which violated the function of normal microflora and reduce colonization resistance contributes to the reproduction of atypical (allochthonous) opportunistic pathogens and engraftment.

Noticed, microbial factor is one of the most important in the event of inflammation. Also in patients with partial loss of teeth, a decrease in the activity of local immune protection factors. In orthopedic treatment of partial loss of teeth prosthesis surface is depom microbial flora of the mouth, and data structures not hygienic.

The aim was to study the microbiota of the oral cavity in patients who are partial dentures depending on the duration of use.

The review of 100 patients who are partial dentures depending on the duration of their use, and formed 4 groups of patients. Among these groups, the first group - the control group comprised 25 patients with partial dentition defects not previously made use of partial dentures. Under the second group (25 patients) - a patient with partial dentures 1 month after prosthesis. The third group (25 patients) - patients with partial dentures 1 year after prosthesis. The fourth group consisted of 25 patients with partial dentures 3-4 years after prosthesis.

We observed that patients for prosthetics was the ІІ highest degree of dysbiosis and almost equal proportions were of I and III degree of dysbiosis.

Patients who used them made partial dentures for 1 month appears that overgrowth and degree characteristic of 37,5% ± 0,15 patients dysbiosis of II degree - 57,5% ± 0,15, dysbiosis of III degree - 5 % ± 0,07.

A small part of the index is not found dysbiosis 10% ± 0,09, almost the same within the ІІІ degree of dysbiosis showed 12,5% ± 0,10. More than 3 times in relation to these indicators was and degree of dysbiosis and at 30% ± 0,14 and was the ІІ highest degree of dysbiosis - 47,5% ± 0,15. These data indicate that there is a stable picture violation of normomicrobiocenosis of mouth that appears as the second degree of dysbiosis and the emergence of a significant third degree dysbiosis.

Most in the 4th group had the ІІ degree of dysbiosis 55% ± 0,22, slightly less than the ІІІ degree dysbiosis - 40% ± 0,21 and only one patient set and degree of dysbiosis - 5% ± 0,10. These data showed that the patient using its reserve forces can not overcome transient microflora low and high virulence, leading to disruption normomicribiocenosis and the pathological process.

With increasing use of the term patients with partial dentures had worse microflora mouth upwards pathogenicity transient microflora of the oral cavity with high virulence.
