Study of adhesion of temporary fixing cements and its change with the addition of the phytocomposition

Abstract

Objective — to study the adhesion of temporary cements and its change with the introduction of phytocomposition in cement composition. Materials and methods. Thirty tear and shear adhesion measurements were carried out for each of 5 temporary cements, with and without phytocomposition. The samples were cemented teeth, cement cuts, teeth with zirconium dioxide, metal or plastic cylinders. Results. The introduction of a phytocomposite into Tempofix non-eugenol reduces the adhesion to break from 14.5 to 18.9%, to shear — from 12.1 to 18.8%. In Temp-Bond NE, a decrease in tensile strength was noted in samples with metal by 13.3%, with plastic by 19.1%, no shear changes were detected. For Repin, a significant decrease in the gap in the tooth-temporary cement-metal was 24.7%, in the shift in the tooth-temporary cement-zirconia — 16.8%. Orthofix-Aqua K and Dentin the Powder in original forms and with the addition of phytocomposite have lower adhesion than the rest of the studied cements. Substitution of water does not lead to a change in adhesion. Conclusion. 1) On devital teeth for long-term fixation Tempofix non-eugenol, Temp-Bond NE and Repin. For short-term — Orthofix-Aqua K and Dentin the Powder. 2) Adding the phytocomposite proposed by us leads to a decrease in the adhesion of temporary cements Tempofix non-eugenol, Temp-Bond NE and Repin, but does not affect the adhesion of cements Dentin the Powder and Orthofix-Aqua K. 3) For prosthodontic treatment on vital teeth for short-term temporary fixation of crowns, Dentin the Powder and Orthofix-Aqua K should be used with their phytocomposite composition, and Tempofix non-eugenol, Temp-Bond NE and Repin with phytocomposition will allow for long-term fixation.
