Molecular-genetic study of gingival sulcus and periodontal pocket contents in individuals with different degrees of hearing loss

Abstract

   The importance of molecular-oriented and genetically-based analyses aimed at studying gingival sulcus and periodontal pocket is becoming an important direction in science, especially in the context of understanding the relationship between the health of the dental alveolar structure and multiple system-wide pathologies.

   The aim of the study was to identify possible mechanisms of interrelation between severity of hearing loss and oral cavity periodontogenes.

   Material and methods. In the course of the work, the dental status was assessed in 120 participants with varying degrees of hearing loss. Microorganisms identification was performed by polymerase chain reaction (PCR) using Multident-5 reagents with control before the start of prevention, after six and twelve months. Every three months, the patient came for examination and received individual recommendations on oral hygiene.

   Results. Significant improvements were recorded in patients with the first, second, third and fourth degrees of hearing impairment compared to the baseline data.

   Conclusion. In patients with mild and moderate hearing loss (1st and 2nd degrees), there is a slight but noticeable decrease in the number of pathogenic microorganisms in the gingival sulcus compared with patients with severe hearing loss (3^rd and 4^th degrees) due to a higher level of hygiene measures. The control of dental hygiene and individual recommendations help to improve the condition of the oral cavity.
