Methods for collecting the contents of the gingival groove (review)

Objective: to analyze the methods and characteristics of instruments for sampling the contents of the gingival groove and/or periodontal pocket forthe subsequent improvement of the instruments used. The literature analysis was carried out with a depth of 36 years (from 1985 to 2021) using the following scientometric databases: PubMed, Scopus, Google Academy, Rospatent, RSCI. This article describes the instruments and methods for taking the contents of the gingival groove and/or periodontal pocket and provides links to 30 scientific publications. An analysis of the literature has shown that many devices and techniques have been proposed to study the contents of the periodontal trough or periodontal pocket, but all of them have certain disadvantages, such as the presence of special equipment, which makes its use limited, high cost of equipment, as well as the difficulty of isolating biological material from the instrument, this worsens the quality of the obtained sample and distorts the results of the study.
