The dynamic of acetone effects to the superficial layer of acrylic teeth in Time Domain C Scan (En Face) OCT non invasive investigations

摘要

The investigation of the dynamics of acetone effects induced to the superficial layer of acrylic teeth with time domain C Scan OCT is the main reason of this study. Acetone is one of the organic solvents used in order to improve the adhesion of acrylic teeth to denture base resin. The ridge lap area of 20 acrylic second upper molars was milled to flat. Afterwards the molars with the milled ridge lap area were cut in two halves. The artificial teeth were randomly assigned in 2 groups. : Group 1. (control) (without treatment),Group 2.Acetone treatment. The both sample groups were submitted to OCT C Scan (En Face) investigation for 200 seconds. The dynamical changes, induced to the superficial layer of acrylic teeth by acetone, among which the superficial layer hardening, were captured with C Scan OCT, proving the fact that time domain C scan OCT could be used in order to investigate the dynamics of the effects of this organic solvent to the polymeric acrylic teeth substrate.
