Changes in the Oral Microbiocenosis in the Process of Different Adhesive Agents Use for Fixation of Complete Removable Laminar Dentures
The use of adhesives to improve the fixation of complete removable laminar dentures, along with numerous benefits for the patient, creates additional risks of imbalance in some representatives of the oral microflora and, consequently, may cause or maintain the development of prosthetic stomatitis and worsen oral hygiene. Therefore, it is important to study the prevention of disorders of the normobiocenosis of the oral cavity due to the differentiated choice of adhesives based on their antimicrobial activity. The study represents the peculiarities of changes in the oral normomicrobiocenosis in the process of the prescribed adhesives’ use for fixing complete removable laminar dentures.
The aim of the study – is to study the changes in the oral microbiocenosis in the process of adhesives use for fixing complete removable laminar dentures and to assess the effectiveness of their choice based on the results.
Materials and methods of the study. There were examined 120 people, who used full removable laminar dentures, 90 of them used adhesive means prescribed by a dentist for three weeks to improve fixation. All patients were sampled for bacteriological examination. Based on the analysis of culture results for microorganisms in each Group, the constancy index was determined – sowing frequency in percent and population level – colonization mass in lg CFU/ml.
Results of the study. In comparison with persons who did not use adhesives to improve the fixation of removable dentures and data before the study it was determined that the adhesive “Corega” had a preservative effect on the normoflora, reduced the population level of pathogenic coccal microflora, yeasts; adhesive “Laсalut” had an inhibitive effect on all representatives of the normal microflora, reduced sowing frequency and population level of β-hemolytic streptococci, but did not affect the pathogenic activity of Staphylococcus aureus, yeasts and gram-negative bacteria; adhesive “Protefix” had a suppressive effect on the normoflora, did not affect the population level of pathogenic microorganisms and even increased the massiveness of colonization by gram-negative bacteria.
Conclusions. Taking into account the determined changes in the oral microbiocenosis in persons who used adhesives to improve the fixation of complete removable laminar dentures, we can talk about the effectiveness of the adhesive “Сorega” for long-term use in the absence of complications in prosthetic bed tissues and with proper hygienic care of the oral cavity; adhesives “Laсalut” and “Protefix” in patients with existing dysbiotic disorders and with subsequent control of the impact on the resident microflora of the oral cavity.
