Prevention of the development of pulp pathology in teeth with endo-periodontal lesions: an in vitro study

Abstract

AIM. To increase the effectiveness of prevention of development of pulp pathology in endo-periodontal lesions in patients with chronic periodontitis.MATERIAL AND METHODS. In the course of the study, instrumental treatment of the outer surface of the extruded teeth was performed, which were divided into 3 groups: group 1 – ultrasonic skeleton “DTE D72” (n = 8); group 2 – Gracey curettes (n = 8); group 3 (control) – no treatment of the root surface (n = 8). Histological analysis of the extradited teeth, scanning electron microscopy of the teeth root surfaces treated, as well as energy dispersion X-ray spectroscopy of the examined nano-preparations were conducted.RESULTS. In the coronal pulp, in 80% of cases, the presence of intrapulmonary calcificates was found, mainly in areas where cement integrity was impaired. Fractures and defects of the tooth root cement are 3 times more common in group 1 of the study than in groups 2 and 3, which correlates with the data of pigment penetration depth in the areas of cement destruction. The most effective obturation of the root outer surface was found in the first study group and amounted to 85%, which is 2 and 4 times more than the indicators of groups 2 and 3, respectively.CONCLUSION. It has been shown that the best method of prevention of pulp pathology at endo-periodontal lesions is the use of Gracie curettes for carrying out hand scaling with subsequent impregnation of the treated tooth root surface with a “Dentin-sealing liquid”.
