Study of saliva pH values in elderly and senile patients with removable plate dentures against the background of xerostomia

The aim of this study was to investigate the pH values of saliva in elderly and senile patients with removable plate dentures against the background of xerostomia.

Materials and methods of the study. To solve the set tasks, the dental clinic of VSMU named after N.N. Burdenko examined and performed orthopedic treatment with removable plate dentures for 80 patients aged 60 to 89 years with missing teeth against the background of xerostomia with the disease coding according to ICD-10 K08.1 Tooth loss due to accident, tooth extraction or localized periodontitis and K11.7 Xerostomia (associated disease). Patients were divided into 4 groups of 20 people, depending on the treatment performed. In all patients of the 4 groups, after the process of collecting mixed saliva, the hydrogen index (pH) was determined using pHSCAN 2.7-10.0 indicator paper with a step of 0.2–0.4.

Results of our own research. Six months after the start of the study, the average pH value of saliva in patients of the 1st group was 6.415±0.023 units, indicating increased acidity. In patients of the 2nd group, the studied value was 7.003±0.023 units, in patients of the 3rd group – 7.100±0.032 (p<0.017) units, and in patients of the 4th group – 7.180±0.026, which corresponded to the normal values. Conclusion. The use of the moisturizing mouth spray «Waterdent» and the immunomodulator «Orvis lysozyme» in elderly and senile patients with xerostomia using removable dentures allowed to increase the pH values of saliva to normal values. However, the best results were obtained in the subjects of the 4th group, whose complex treatment included the cleaning and disinfecting agent for removable dentures «Waterdent».
