Introduction. Treatment of chronic periodontitis remains an urgent problem in modern dentistry. This pathology makes up 15–30% of the total number of dental diseases.
Despite the progress made in the treatment of chronic periodontitis, a very large number of complications after treatment of this disease is observed.
Aim. The aim of our study is the comparative evaluation of the antibacterial activity of modern filling materials that are used in modern dentistry in the treatment of chronic periodontitis.
Materials and methods. The study determined the sensitivity of microflora of pathogenic focus of inflammation to filling materials; it was found out that Staphilococcus haemoliticus and Streptococcus haemoliticus were sensitive to the filling material “Endofill” (the area of stunted growth averaged 20–22 mm) and had moderate sensitivity to the filling material “Metapex” (area of stunted growth averaged 10–15 mm) to the filling material “AH Plus” microflora remained stable. Staphilococcus aureus is sensitive to the filling material “Metapex” (area of stunted growth averaged 20–23 mm) and is moderately sensitive to the filling material “Endofill” (area of stunted growth averaged 11–15 mm), resistant to the filling material “AH Plus”.
Conclusion. According to the high pathogenicity and virulence microflora of the odontogenic inflammatory focus, which is represented generally by facultative anaerobes, such as: Streptococcus haemoliticus (80%), Staphilococcus haemoliticus, Staphilococcus aureus, it should be noted that chronic periodontitis of the upper jaw is a great danger for the maxillary sinus. “Endofill” had the highest activity against microorganisms of the periapical focus and the sensitivity to which was identified in the most number of microorganisms.
