EFFECT OF DIFFERENT TOOTHPASTES ON SELECTED BIOCHEMICAL PARAMETERS OF ORAL FLUID IN MIDDLE-AGED PATIENTS

Abstract

Purpose of the study was to evaluate biochemical changes in the oral fluid of middle-aged patients following the use of modern toothpastes. Research methods. A total of 61 volunteers aged 40–57 years were examined.Participants used different types of Lacalut toothpaste for one month, after which all groups were switched to Natusana Bio Calendula toothpaste. Examinations were performed at baseline, and after 1, 3, and 6 months. In the oral fluid of middle-aged patients, the degree of microbial contamination (by urease activity), the level of antimicrobial defense (by lysozyme activity), and the inflammatory status of oral tissues (by elastase activity) were assessed. Scientific novelty. It was established that all investigated toothpastes contributed to a significant reduction of urease activity (by 1.4–1.6 times, p < 0.01), which indicates a decrease in bacterial contamination of the oral cavity. The most pronounced and stable effect was observed with Lacalut “Extra sensitive”, which not only ensured more consistent suppression of urease activity over six months but also promoted significant biochemical changes in oral fluid. In particular, an increase in lysozyme activity (1.7-fold) was recorded, indicating enhanced antimicrobial protection, along with an almost twofold reduction in elastase activity, which reflects a decrease in inflammatory processes in oral tissues. Even after discontinuation of toothpaste use, protective indicators remained significantly higher than baseline values, highlighting the importance of regular and continuous application. Conclusions. Thus, the use of modern toothpastes, especially the Lacalut “Extra sensitive” formulation, is an effective means of preventing dental diseases in middle-aged patients. The results confirm the expediency of regular and long-term use of individually selected oral hygiene products.
