ABSTRACT
Therapeutic measures in patients with increased tooth erosion are aimed at restoring teeth, however, after the treatment of such teeth a significant number of complications in the form of chipping and loss of fillings are observed.
The aim of the study. To determine experimentally the mechanical strength of the filling-post connection; to evaluate clinically the effectiveness of the use of hardened parapulpal posts in patients with tooth erosion.
Objects and methods. The resistance of fillings to mechanical impact and bonding strength at the filling-post interface were evaluated on tooth slides. The efficacy of parapulpal restorations for patients with tooth erosion was evaluated on 220 teeth. The integrity of the restorations was determined after 12-18 months of use.
Results and discussion. It was shown that when using filling materials for the fabrication of structures reinforced with parapulpal posts, the highest microhardness of the filling-post interface was obtained for the post-fluid composite connection, and the lowest – for the post-glass ionomer cement connection. Analysis of the results of the study of the clinical condition of restorations showed that the use of parapulpal posts in the fabrication of constructions on teeth with pathologic erasability reduces the number of complications occurring in the long term by 21.75 %.
Conclusion. The obtained results are used to develop recommendations for the fabrication of structures reinforced with posts.
Keywords: microhardness, tooth erasability, parapulpal posts
