| description | The purpose of the study was to determine the effect of tricalcium silicate cement on the protective process of pulp in the treatment of reversible pulpitis. There was carried out an experiment on 3-month-old male rabbits to study morphofunctional changes in the pulp tissue with modeling of reversible pulpitis followed by vital amputation with coating of the pulp with tricalcium silicate (8 animals, study group) and mineral trioxide aggregate (MTA) (8 animals, comparison group). In 2 and 6 weeks dental tissues were fixed by 10% formalin solution and after decalcification and done routine procedures, histological sections were made, stained with hematoxylin and eosin. After the application of tricalcium silicate cement in 2 weeks, the odontoblast density changed to 3.92±1.03×103/mm2 from 8.3±1.02×103/mm2 of cell density in the intact group. The number of neutrophils also plays a big role in the regeneration of inflamed pulp. Thus, in 2 weeks the number of neutrophils made up 6.39±2.61x102 per 1 mm2, which is 3 times less than after mineral trioxide aggregate usage – 19.49±2.85x102per 1 mm2. It was established that the processes of rheological disorders with impaired lymph circulation are replaced by the restoration of the cellular component. In such a way the proposed vital amputation was examined for reversible pulpitis and it revealed similar clinical and pathological effectiveness with a positive regenerative process with formation of a sufficient number of odontoblasts (7.98±1.51×103/mm2) for the subsequent formation of a hard tissue bridge, which consists of collagen fibers in the form of a frame. The main goal of vital amputation procedure is regeneration (proliferation) of the pulp with a short-term signs of alteration and exudation, which is provided by the choice of material for the pulp covering. Thus, after the vital amputation of the pulp, followed by the use of tricalcium silicate cement 6 weeks after, the number of neutrophils was 1.39±0.72x102per 1 mm2, which is 5 times less than after using mineral trioxide aggregate. |
