In vitro evaluation of three temporary tissue conditioners submitted to penetration tests
Journal Title: RSBO - Year 2009, Vol 6, Issue 1
Abstract
Introduction and objective: The aim of this study was to evaluate resilience changes of four tissue conditioners:Coe Comfort (CC), Ufi-Gel (UG), Sofreliner S (SS) and Sofreliner MS (SMS), associated to their respective surface sealers at different times.Material and methods: A hundred and sixty capsules of acrylic resin were made and then finished prior to the filling with the tissue conditioners.For the CC group the capsules were not treated and were filled with the material.For the conditioners UG, SS and SMS, the capsules were internally treated prior to the material insertion.All the materials were used following the manufacturer’s instructions.The tests were carried out after 1h, 24h, 30 days and 60 days.Results:The effect of time at the materials resilience was evaluated and it was observed that CC loses more resilience than UG, SS and SMS, what proofs that its use is limited only to a short period. UG, SS and SMS, despite having a little resilience deficiency in the first moment, showed better results after 60 days.Conclusion: It was concluded that silicon based materials keep its initial characteristics till 60 days, while acrylic resin based materials progressively lose its viscoelasticity.
