“…he digital speckle pattern interferometry (DSPI) is a fullfield optical measurement technology, which has the advantages of being contactless, providing a real-time measurement, and having high precision and sensitivity [1]. Due to its characteristics, it has been widely applied to the fields of non-destructive testing [2,3], biomedical testing [4,5], precision machinery manufacturing [6], vibration measurement [7], and material's mechanical properties evaluation [8]. The final physical quantity is determined by calculating the interferogram of the DSPI.…”

Evaluating the filtering process of the digital speckle pattern interferometry (DSPI) of a single image by the traditional methods can result in under-or over-filtering. To solve this problem, this paper proposes an image-filtering evaluation method based on the Sobel operator and image entropy. First, the Sobel operator is introduced to convolute a filtered image to obtain a gradient image of a DSPI. Then, by analyzing the gradient image, image entropy is calculated according to the characteristics of the gradient map. Finally, the proposed method is verified by experiments. The experimental results show that the proposed method can quantitatively evaluate the filtering process of the DSPI.

“…The efficient diagnosis of periodontal diseases includes the determination of the quantitative and qualitative compositions of the oral cavity microflora. Globally, the following laboratory methods are used for identifying periodontal microorganisms: bacteriological, microscopic, immunological and molecular diagnosis, as well as biochemical determination of microorganism fermentation action markers and tissue destruction and inflammation markers [10][11][12][13][14].…”

Currently, the advanced studies have been justified and implemented in the Republic of Belarus that enable the production and a practical use of a domestic rapid test and allow dentists to apply microbiological diagnosis methods.The objective of the study was to develop a domestic rapid test for periodontology, indicating the procedure for preparatory clinical and laboratory measures using PCR and trypsin-like activity of periopathogenic microflora (Treponema denticola, Porphyromonas gingivalis, Bacteroides forsythus)Dental examination was performed in 60 patients with clinical signs of generalized periodontitis and a 5‒6 mm deep pathological dentogingival pocket (PDGP), aged 35–44 (the main group), and 140 patients without signs of periodontal diseases, aged 20–24 (the control group). These patients were selected among the visitors of Chair No. 3 of the Belarusian State Medical University. The laboratory diagnosis was made using PCR and evaluating the trypsin-like activity of periopathogenic microflora.The algorithm of preparatory clinical and laboratory measures was suggested for diagnosis of periodontal diseases, including material sampling and identification of periopathogenic microorganisms in the sample using a biochemical method; sampling, preservation and storage of material for quantitative PRC testing; and the identification of the genetic material of periopathogenic microorganisms by means of a real-time quantitative PRC method.The basic principles of microbiological diagnosis in periodontology enable making a true diagnosis, planning treatment and assessing the treatment results.We examined the content of the gingival sulcus and/or the periodontal pocket in patients who have periodontal diseases. It was noted that the most rational tools for removing the periodontal pocket content in patients with periodontal diseases was a paper pin.The development of a domestic express test in periodontology demonstrated the need of preparatory clinical and laboratory activities using PCR and trypsin-like activity of periopathogenic microflora (Treponema denticola, Porphyromonas gingivalis, Bacteroides forsythus).

“…Более того, в эстетически значимых зонах этот параметр становится определяющим при реконструкции как альвеолярных, так и периодонтальных дефектов. Однако в настоящее время отсутствует классификация, которая позволила бы учитывать симультанно представительство костного компонента, степень и характер мягкотканного комплекса [16][17][18][19].…”

The efficacy and long-term outcomes of the procedure of guided tissue regeneration depend on the basic morphometric condition of the defect and the choice of the technical supplement and the technical approach to surgery. Hystoarchitectonics of defects can be presented as a simplified four-parameter classification for use in clinical and expert practice in addition to making decisions in the regenerative surgery of defects in the periodontal and alveolar ridge.
